Spider Overview

Spiders dominate the invertebrate pet hobby, with tarantulas leading as the most widely kept invertebrate pets worldwide and various true spiders attracting dedicated keeping communities of their own. This popularity reflects genuine suitability for captive life combined with fascinating behaviors, striking appearances, and manageable care requirements for many species. Understanding the broad landscape of spider keeping helps prospective keepers identify which groups align with their interests and capabilities while appreciating the remarkable diversity these animals represent.

Tarantulas account for most spider keeping activity, supported by extensive captive breeding programs, well-established care knowledge, and species ranging from absolute beginner options to challenging specialists that test expert keepers. The tarantula hobby has developed sophisticated infrastructure including dedicated forums, breeding networks, and specialty suppliers that make entering and advancing in the hobby straightforward for those willing to learn. This established foundation makes tarantulas the logical starting point for most people interested in spider keeping, providing resources and community support unavailable for more obscure invertebrate groups.

True spiders beyond tarantulas receive less attention but offer unique keeping experiences unavailable with their larger relatives. Jumping spiders have developed passionate followings based on their apparent intelligence, remarkable vision, and interactive behaviors that set them apart from most invertebrates. Orbweavers, fishing spiders, and various hunting spiders attract keepers interested in observing predatory behaviors and web construction. These alternatives suit keepers seeking something different from the standard tarantula keeping experience, though they require different approaches and often have less documented care information available.

The diversity within spiders means generalizations only go so far before species-specific knowledge becomes essential. A desert tarantula and a rainforest tarantula share fundamental biology but require different environmental conditions. A jumping spider and an orbweaver both belong to true spiders but differ dramatically in behavior, hunting strategy, and keeping approach. Spider keeping rewards specificity over generality, with success following from understanding particular species rather than applying broad assumptions about spiders in general.

This article provides orientation to spider keeping as a whole, helping you understand the major groups, their general characteristics, and which paths might suit your interests. Consider it a map of the territory rather than detailed directions for any specific destination. From this overview, you can identify which directions appeal to you and pursue species-specific knowledge for the animals that capture your interest.

Tarantulas belong to the infraorder Mygalomorphae, distinguished from true spiders by their parallel fangs, generally larger size, and longer lifespans. Female tarantulas of many species live twenty years or more, with some approaching thirty years in captivity. This longevity represents genuine commitment but also means well-chosen tarantulas become long-term companions rather than temporary pets. Males live significantly shorter lives, typically five to ten years depending on species, with maturity marking the beginning of their final phase rather than peak condition.

The tarantula hobby conventionally divides species into Old World and New World categories based on their geographic origin, a distinction carrying practical significance beyond mere taxonomy. New World tarantulas from the Americas typically possess urticating hairs they can kick toward threats, causing irritation but rarely serious harm. Old World tarantulas from Africa, Asia, and Australia lack these hairs but generally compensate with more potent venom and faster defensive responses. This pattern shapes species recommendations, with New World species dominating beginner lists while Old World species typically suit more experienced keepers prepared for faster, more defensive animals.

True spiders in the infraorder Araneomorphae encompass the vast majority of spider species, characterized by opposing fangs that work like pincers rather than the parallel downward-striking fangs of tarantulas. Most true spiders live much shorter lives than tarantulas, typically one to three years, with some larger species extending somewhat longer. This compressed lifespan means faster turnover and different relationship dynamics than the multi-decade commitment some tarantulas represent. For keepers wanting engagement without decades-long obligation, true spiders offer compelling alternatives.

Jumping spiders have emerged as particularly popular true spider pets because of their exceptional vision and seemingly curious personalities. Unlike most spiders that rely primarily on vibration and touch, jumping spiders possess acute vision through their large forward-facing eyes, creating an impression of engagement with their environment and their keepers that other spiders lack. Their hunting strategy involves stalking and leaping rather than web construction, making them active and observable in ways that sit-and-wait predators are not. Many keepers describe jumping spiders as having more apparent personality than other invertebrate pets.

Web-building spiders including orbweavers and various comb-footed spiders attract keepers interested in observing construction behaviors and the remarkable engineering of spider silk structures. These species require enclosure designs that accommodate web building, often meaning taller vertical spaces with anchor points for attachment. Watching web construction from initial framework through completed spiral provides engaging observation unavailable with hunting spiders or tarantulas. The structures themselves demonstrate sophisticated engineering evolved over hundreds of millions of years.

Hunting spiders beyond jumping spiders include wolf spiders, fishing spiders, and various other groups that pursue prey actively rather than trapping it passively. These spiders display different behaviors than either web builders or ambush predators, and their keeping approaches reflect these differences. Some hunting spiders tolerate communal keeping while most require individual housing to prevent cannibalism. Understanding the specific behavioral patterns of your chosen hunting spider guides appropriate enclosure design and husbandry approach.

Beginner tarantulas share characteristics that make them forgiving for new keepers learning fundamental skills. Species like Brachypelma hamorii, Grammostola pulchripes, and Tliltocatl albopilosus tolerate condition variations, eat readily, display calm temperaments, and survive the mistakes inevitable while someone develops husbandry competence. These species appear on recommendation lists repeatedly because generations of keepers have learned successfully with them, not merely because they're widely available. Their forgiving nature teaches skills without punishing the learning process with dead animals.

Intermediate tarantulas require more precise conditions or display faster defensive responses but remain manageable for keepers who have developed solid fundamentals with easier species. Moving from beginner to intermediate species represents natural progression as competence develops, though the transition should follow demonstrated success rather than arbitrary timelines. Keepers who rush this progression often discover they lack skills intermediate species demand. The jump should feel like reasonable next step rather than dramatic leap.

Advanced tarantulas include species with challenging humidity requirements, defensive temperaments that complicate routine care, medical significance from venom, or specialized needs beyond typical husbandry approaches. Old World species often fall into this category not because they're inherently more difficult to maintain but because their defensive speed and venom potency raise consequences for keeper errors. Success with advanced species typically requires years of accumulated experience across multiple easier species.

Jumping spider species commonly kept include bold jumping spiders native to North America and various Phidippus species with striking colors and relatively robust care tolerance. These species suit beginners to the true spider side of the hobby, offering engaging behaviors in compact enclosures without demanding precise environmental control. Their shorter lifespans mean faster cycles but also lower long-term commitment than tarantulas. The engaging behaviors compensate for briefer keeping relationships.

Other true spider groups attract more specialized keeping interest with varying levels of established husbandry knowledge. Orbweavers fascinate those interested in web construction behavior, though keeping approaches vary by species and available documentation remains less comprehensive than for tarantulas. Wolf spiders appeal to keepers wanting active hunters. Fishing spiders offer unusual semi-aquatic keeping opportunities. Each group requires specific approaches, and keepers interested in these alternatives benefit from seeking species-specific guidance rather than applying general spider care assumptions.

Before acquiring any spider, research the specific species thoroughly to understand its particular requirements rather than relying on general spider care information. A tarantula from humid forests needs different conditions than one from arid scrubland. A web-building spider needs different enclosure design than a hunting spider. Species-specific knowledge prevents the assumption errors that harm animals and frustrate keepers who believe they're providing appropriate care.

Enclosure design varies significantly across spider groups. Terrestrial tarantulas need horizontal floor space with appropriate substrate depth for burrowing species. Arboreal tarantulas require vertical space with climbing surfaces and elevated retreat options. Web-building true spiders need anchor points for web attachment and usually vertical orientation. Jumping spiders thrive in well-ventilated enclosures with visual complexity and hunting opportunities. Matching enclosure to species represents fundamental keeping practice.

Feeding approaches differ based on spider size, species preferences, and life stage. Most tarantulas accept appropriately sized crickets, roaches, or other feeder insects offered weekly to bi-weekly depending on size and species. Smaller true spiders may need fruit flies or other tiny prey, graduating to larger feeders as they grow. Overfeeding causes problems as serious as underfeeding, with excessive prey items stressing spiders and creating enclosure hygiene issues.

Temperament assessment matters practically for routine maintenance. Calm species allow enclosure opening, substrate changes, and other care activities without defensive responses. Defensive species require more careful handling of maintenance tasks, using tools rather than hands near the animal and moving slowly to avoid triggering threat responses. Understanding your specific spider's temperament through observation guides how you approach necessary care activities.

Long-term planning differs dramatically between tarantula keeping and true spider keeping. A female tarantula may live two decades or more, representing commitment comparable to a dog or cat. True spiders typically live one to three years, meaning faster turnover and different relationship expectations. Both timeframes suit different keeper preferences, and honest assessment of what you want from the keeping experience helps guide appropriate species selection.

Treating all spiders identically ignores the diversity that makes spider keeping interesting but also demanding. Care sheets for one species don't transfer directly to another, even closely related species may require different approaches, and assumptions based on general spider biology miss species-specific needs. The keeper who learns appropriate care for their specific species succeeds where those applying generic spider husbandry fail.

Underestimating tarantula lifespan leads to commitment mismatches that harm animals when keepers' circumstances change. A twenty-year-old will approach forty by the time their female tarantula approaches natural lifespan limits. Housing changes, family formation, career moves, and shifting interests all occur across tarantula lifespans. Acquiring these animals without considering decades of care represents poor planning that sometimes ends with abandoned or rehomed animals.

Mishandling defensive species produces negative outcomes ranging from escaped spiders to painful bites to urticating hair reactions. Species descriptions as defensive or fast exist to guide keeper approach, not to describe personality flaws requiring correction. Attempting to handle species that tolerate handling poorly, or approaching any spider when it displays threat postures, invites exactly the consequences experienced keepers warn against.

Inadequate ventilation particularly harms true spiders kept in containers designed for humidity retention rather than air exchange. While some species require elevated humidity, stagnant air promotes mold growth and respiratory issues. Enclosure design must balance humidity maintenance with air circulation, which often means more ventilation than beginners expect necessary. Stuffy enclosures kill spiders even when temperature and humidity parameters appear appropriate.

Overfeeding creates stress and health issues while wasting resources on prey that spiders don't need. Tarantulas and other spiders can fast for extended periods without harm, and feeding more frequently than necessary doesn't benefit animals. Weekly or bi-weekly feeding suits most species, with many doing fine on even less frequent schedules. The impulse to feed more often reflects keeper psychology rather than spider nutritional needs.

Spider keeping offers remarkable diversity from the extensively documented world of tarantula keeping through the emerging communities around jumping spiders and various true spider groups. This diversity means opportunities exist for nearly any keeper interest, but also means general spider knowledge only provides foundation for species-specific study. Successful spider keeping follows from understanding particular species rather than applying broad assumptions across fundamentally different animals. The investment in species-specific research pays dividends through healthy animals and enjoyable keeping experiences.

Tarantulas provide the most accessible entry into spider keeping because of their established hobby infrastructure, extensive breeding programs, and species ranging from extremely forgiving to genuinely challenging. New keepers benefit from starting with recommended beginner species rather than selecting based on appearance, building competence through success with easier animals before progressing to more demanding species. This systematic approach protects animals while developing keeper capability and establishes the skills that serve throughout keeping careers.

True spiders offer alternatives to tarantula keeping for those seeking different experiences with shorter commitment timeframes. Jumping spiders provide engaging interactive behaviors uncommon among invertebrates, appearing to watch and respond to their environment in ways that create surprisingly personal keeping relationships. Web builders display construction engineering remarkable in its sophistication. Various hunting spiders offer active predatory observation. These alternatives typically involve shorter lifespans and different care approaches than tarantula keeping, suiting different keeper preferences and commitment levels.

Species-specific research before acquisition prevents the assumption errors that harm animals and frustrate keepers regardless of which spider group interests you. What works for one spider species may fail completely for another, even within the same genus. The time invested in understanding particular species before bringing them home pays dividends through successful keeping experiences rather than struggling with animals whose needs you don't actually understand. The hobby rewards preparation over impulse at every experience level.
