Massive Central American Tarantula – A Calm Giant

​Sericopelma angustum, native to Panama, is a large and massive terrestrial tarantula, valued by breeders for its impressive size and generally calm temperament. Known as the Panamanian Brown Tarantula, it stands out with its dark, velvety coloration and robust body. This species has a relatively gentle disposition, making it a good choice for intermediate keepers.

​Natural Habitat and Geographical Origin

​S. angustum inhabits dry and semi-dry areas of Panama. It leads a terrestrial lifestyle, digging deep burrows in the ground or using natural crevices under rocks and roots as shelter.

​Morphology and Size

​Adult Sericopelma angustum specimens reach a leg span of up to 18-20 cm (7-8 inches). Their body is very massive and sturdily built, covered with dense, velvety black or dark brown hairs. The carapace is often slightly lighter, brown. The entire spider has a uniform, dark color, giving it a classic yet impressive appearance.

​Behavior and Character

​S. angustum is a species with a generally calm and stable temperament, although it is larger and more dynamic than typical Brachypelma. When threatened, it rarely shows aggression, preferring to flee or kick urticating hairs from its abdomen. These hairs can cause significant irritation and itching on human skin. Bites are rare, and their venom is mild and does not pose a serious medical threat to humans, comparable to a bee sting.

​Feeding Habits

​In nature, their diet consists of insects and other small invertebrates. In home captivity, they should be fed appropriately sized feeder insects, such as large crickets, cockroaches (e.g., Argentinian roaches), or locusts. Adults can be fed once a week or once every two weeks, and their appetite is impressive.

​Lifespan

​Female Sericopelma angustum are long-lived and can live for 15 to 20 years under optimal breeding conditions. Males have a significantly shorter lifespan, typically 3 to 5 years.

​Husbandry Requirements

​Terrarium: For an adult specimen, a spacious terrarium of at least 35x25x25 cm is required. Good ventilation is crucial.

​Substrate: A layer of substrate about 10-15 cm deep should be placed at the bottom of the terrarium, e.g., coconut fiber or a mixture of peat and vermiculite, which retains moisture well and allows for burrowing.

​Hide: A permanent, large hide should be provided (e.g., a piece of bark, a large coconut half, a ceramic pot).

​Temperature: The ideal temperature ranges from 24 to 28°C.

​Humidity: The recommended humidity is 70-80%. This can be maintained by misting part of the substrate every few days.

​Water: A shallow water dish should always be available and refilled regularly.

​Suitable for Hobbyists

​Sericopelma angustum is a species intended for intermediate keepers. Its impressive size, gentle nature, and resilience make it a satisfying and spectacular species to observe.
