Costa Rican Zebra Tarantula
Aphonopelma seemanni
The Aphonopelma seemanni, famous as 'Costa Rican Zebra'. It is an unmistakable terrestrial/burrowing tarantula: dark black or chocolate brown body (4.7-5.5 inches legspan) broken by bright creamy-white (or yellow) longitudinal stripes on all legs, resembling those of a zebra. Unlike the docile North American cousins (chalcodes), the seemanni is fast, nervous, a formidable digger and requires a very deep and humid substrate, typical of tropical climates.

Descrição da espécie
Geographic Origin and Habitat: World Spider Catalog lists Aphonopelma seemanni from El Salvador, Honduras, Nicaragua, and Costa Rica. This taxonomic distribution entry does not characterize habitat conditions.
Taxonomy and Genetics: World Spider Catalog lists Aphonopelma seemanni (F. O. Pickard-Cambridge, 1897) as an accepted species in Theraphosidae. Its edit history records the 2023 synonymy of Aphonopelma latens with A. seemanni; the catalog entry does not provide genetic results.
Behaviour and Habits: The cited taxonomic catalog does not provide behavioural observations for this species.
Morphology and Sexual Dimorphism: The cited taxonomic catalog entry does not provide a morphological description or sexual-dimorphism measurements; none are inferred here.
Cuidado, criação e companheiros de tanque
Terrarium Setup: The cited study observed female tunnel entrances in a rocky grassland with isolated trees at Pozo Azul, Abangares, Guanacaste, Costa Rica. It is a field observation, not a captive enclosure protocol; it does not provide enclosure dimensions or a substrate specification.
Lighting and Heating: In the Guanacaste rainy-season observations, females were predominantly nocturnal, with greatest activity between 6:30 p.m. and 6:30 a.m. and low daytime activity. This field pattern is not a prescribed lighting or heating schedule.
Humidity and Hydration: The source reports observations in the rainy season and does not quantify humidity or state a captive humidity target. Seasonal field context must not be converted into a terrarium requirement.
Feeding and Supplementation: This study does not report diet, prey quantities, supplementation, or a feeding schedule; no feeding recommendation is added here.
Compatibility and Coexistence: The study monitored female activity at individual tunnel entrances and does not assess cohabitation; it provides no compatibility recommendation.
Health and Common Diseases: No disease, treatment, or veterinary-management data are reported in this field-activity study.

Perfil de invertebrados terrestres
- Dieta
- Carnivore
- Aphonopelma seemanni is an opportunistic ambush predator that thrives on a diet of appropriately sized live insects. Crickets, roaches, and mealworms make excellent staple feeders for this species. Prey should be gut-loaded and occasionally dusted with supplements to ensure optimal nutrition. It is important not to overfeed, as a highly distended abdomen can increase the risk of fatal injuries from falls. Remove any uneaten live prey after 24 hours to prevent them from stressing or injuring the spider.
- Tamanho adulto
- 15 cm
- Estilo de vida/Microhabitat
- Fossorial
- Aphonopelma seemanni is perfectly adapted to its specific ecological niche, requiring a setup that closely mimics its natural environment. Terrestrial species need deep, specialized substrate for burrowing, while arboreal species require vertical cork bark tubes and elevated hides. They are generally solitary creatures that should be housed individually to prevent predation. A proper water dish and an appropriate microclimate are essential components of their enclosure. They lead a sedentary lifestyle, meaning they do not require excessively large enclosures compared to active reptiles.
- Ciclo de atividades
- Nocturnal
- Like most tarantulas, Aphonopelma seemanni is primarily nocturnal, showing the highest levels of activity during the night. They generally remain hidden in their burrows or web tubes during daylight hours to avoid heat and predators. Once the lights go out, they often emerge to sit at the entrance of their hide, waiting to ambush passing prey. Despite being mostly inactive during the day, they may occasionally venture out for water or to adjust their webbing. Maintaining a natural photoperiod is recommended to support this internal circadian rhythm.
- Socialidade
- Solitary
- It is a fiercely solitary and aggressively cannibalistic species. Specimen should never be cohabitated under any circumstances. They view any other tarantula, even of the same species, as either a territorial threat or a potential meal. Interaction is strictly limited to dangerous, brief mating encounters.
- Reprodução
- Oviparous
- Breeding Aphonopelma seemanni requires careful introduction of the mature male to the female's enclosure to minimize the risk of cannibalism. The male will drum on the substrate to announce his presence and gauge the female's receptivity. After a successful mating, the female will construct an egg sac containing hundreds of eggs. She will guard this sac fiercely for several weeks until the spiderlings emerge. Providing optimal temperature and humidity during this incubation period is critical for the success of the clutch.
- Venenoso
- Yes
- Tolerância de tratamento
- With caution
- Handling Aphonopelma seemanni is generally discouraged by experienced keepers, as it provides no benefit to the spider and introduces significant risks. A fall from even a minor height can rupture their delicate abdomen, resulting in fatal injury. Additionally, they can deliver a painful bite or release irritating urticating hairs if they become stressed or defensive. If they must be moved for enclosure maintenance, the "catch cup" method is the safest and most stress-free approach. Always prioritize the safety and well-being of the animal over the desire to interact physically.
- Brumação
- Não obrigatório
- Tarantulas like Aphonopelma seemanni do not undergo true brumation, but their metabolism may slow down considerably if exposed to cooler winter temperatures. In captivity, it is best to maintain a stable, warm temperature year-round to ensure healthy growth and digestion. If temperatures do drop slightly, you may notice a decrease in appetite and activity levels. Never allow the enclosure to reach freezing temperatures, as this will quickly prove fatal. Heating should always be provided via a thermostat-controlled heat mat applied to the side, never the bottom, of the tank.
- Muda
- Regular
- Molting is a critical and vulnerable process for Aphonopelma seemanni, allowing it to grow and regenerate lost appendages. Before molting, they often refuse food for weeks, become sluggish, and may spin a molting mat of webbing. They will typically flip onto their back to shed their old exoskeleton—never mistake a spider in this position for a dead one. It is crucial to maintain adequate humidity during this time and strictly avoid feeding them until their fangs have fully hardened. Disturbing a tarantula mid-molt can be fatal, so they must be left completely alone.
