Skeleton Tarantula
Ephebopus murinus
The Ephebopus murinus, legendary as the 'Skeleton Tarantula'. Cousin of the 'Blue Fang', it is an extreme fossorial burrower (4.7-5.9 inches legspan) very famous for the iconic 'skeleton' pattern on the front legs: vivid creamy-white (or golden) parallel stripes that stand out on the dark brown body. Similar to its cousin, it launches urticating hairs from the pedipalps (and not from the abdomen) and is equally neurotic and lightning fast in defensive bites. It has an absolute need for humid and very deep substrate, living sealed in intricate tubes of silk and mud. A defensive and unforgiving creature, recommended only to veterans.

Descrição da espécie
Geographic Origin and Habitat: World Spider Catalog lists Ephebopus murinus from French Guiana, Suriname and Brazil. This taxonomic distribution entry does not characterize habitat conditions.
Taxonomy and Genetics: World Spider Catalog lists Ephebopus murinus (Walckenaer, 1837) as an accepted type species in the genus Ephebopus, family Theraphosidae. The 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 does not provide a morphological description or sexual-dimorphism measurements; none are inferred here.
Cuidado, criação e companheiros de tanque
Terrarium Setup: In a field study in French Guiana, Marshall and West (2008) observed early-instar Ephebopus murinus constructing above-ground silken tubular retreats among low vegetation, then shifting to a fossorial lifestyle when subadult. This is an ontogenetic field observation, not an enclosure design or substrate prescription.
Lighting and Heating: The cited field study does not provide a captive lighting or heating schedule.
Humidity and Hydration: The cited study does not quantify a captive humidity or hydration target.
Feeding and Supplementation: The cited study does not document a captive feeding or supplementation protocol.
Compatibility and Coexistence: The cited study does not evaluate captive cohabitation.
Health and Common Diseases: The cited study does not provide disease, treatment, or veterinary-management evidence. In its French Guiana sample, terrestrial Bromelia predicted the placement of above-ground retreats and leaf litter predicted burrow placement; these associations are not husbandry instructions.

Perfil de invertebrados terrestres
- Dieta
- Carnivore
- The diet of Ephebopus murinus primarily consists of appropriately sized live insects, such as crickets, roaches, and mealworms. In the wild, they are opportunistic ambush predators that will take down any prey they can overpower. Feeding should occur once or twice a week depending on the size and age of the individual. It is important to remove any uneaten prey after 24 hours to prevent stress or injury to the tarantula. Fresh water must also be available at all times in a shallow dish.
- Tamanho adulto
- 15 cm
- Estilo de vida/Microhabitat
- Fossorial
- The lifestyle of Ephebopus murinus revolves around creating and maintaining a suitable retreat, whether that be a deep burrow or an intricate web structure. Terrestrial species will spend significant time digging and moving substrate to form a comfortable living space. Arboreal types, on the other hand, will construct silken tubes hidden among foliage or bark. They lead highly solitary lives and will generally not tolerate the presence of other individuals in their territory outside of mating. A well-designed enclosure that mimics their specific natural habitat is essential for their overall well-being.
- Ciclo de atividades
- Nocturnal
- The activity pattern of Ephebopus murinus is predominantly nocturnal, meaning they are most active during the night. As dusk approaches, they typically emerge from their retreats to actively forage for food or wait in ambush. During the daylight hours, they prefer to remain hidden in dark, secure hiding spots to avoid predators and extreme temperatures. Maintaining a proper day-night light cycle in the enclosure helps regulate their natural circadian rhythms. Observing them under a dim red light at night can provide fascinating insights into their natural habits.
- Socialidade
- Solitary
- They exhibit extremely solitary behavior and are notorious for being highly cannibalistic toward conspecifics if forced into close proximity. Cohabitation is strictly impossible; therefore, individual housing is an absolute necessity from the earliest stages of life to prevent fatal encounters and ensure the survival of every specimen.
- Reprodução
- Oviparous
- Reproduction in Ephebopus murinus typically involves a delicate courtship process where the male drums on the ground to signal his presence to the female. Once the female accepts, the male carefully approaches to transfer sperm using his pedipalps. After a successful mating, the female will construct an egg sac containing anywhere from fifty to several hundred eggs, depending on the species size. Incubation lasts for several weeks, during which the female fiercely guards the sac. Eventually, the spiderlings emerge and will soon disperse to begin their solitary lives.
- Venenoso
- Yes
- Tolerância de tratamento
- With caution
- Handling Ephebopus murinus should generally be kept to an absolute minimum to avoid causing unnecessary stress to the animal. Tarantulas are fragile creatures that can suffer fatal injuries from even a short fall. If manipulation is required for enclosure maintenance or rehousing, using a catch cup or the soft paintbrush method is highly recommended. Direct handling carries the risk of getting bitten or exposed to irritating urticating hairs. Prioritizing observation over interaction ensures the safety of both the keeper and the spider.
- Brumação
- Não obrigatório
- True brumation is not typically observed in Ephebopus murinus, but they may experience a period of reduced activity during cooler winter months. During this time, they might retreat deeper into their burrows and significantly decrease their food intake. It is important to avoid overfeeding and to carefully monitor the temperature and humidity levels to ensure they remain within safe parameters. Keepers should refrain from disturbing the spider to allow it to rest naturally. Normal activity and appetite will usually resume once ambient temperatures begin to rise again in the spring.
- Muda
- Regular
- The molting process is a critical and vulnerable time for Ephebopus murinus as it allows them to grow and regenerate lost appendages. Prior to a molt, the tarantula will often refuse food, become lethargic, and develop a dark patch on its abdomen. When the time comes, they will construct a molting mat of silk and flip onto their backs to begin extracting themselves from their old exoskeleton. Under no circumstances should they be disturbed or fed during this exhausting process. After molting, they need several days to weeks to fully harden their new fangs and body before they can eat again.
