Megaphobema robustum
A large terrestrial tarantula from Colombia with a jet-black body and vivid orange legs, reaching a leg span of 20cm. Its hind legs carry heavy spines, and when alarmed it spins its whole body and lashes out with them, a defence seen in no other genus.
Megaphobema robustum is a large terrestrial tarantula of the Colombian tropical rainforest, reaching a leg span of 15-20 cm. Against a deep black carapace and abdomen, the legs apart from the femora are clothed in bright orange setae, making it one of the most strikingly coloured species in the genus. It shelters in burrows dug beneath fallen logs to escape daytime heat and is active at night. Rows of large spines arm the hind legs, and when threatened it extends all its legs, rotates its whole body and strikes at the aggressor with them, a defence not seen in related genera. It also kicks urticating setae. Room temperature is sufficient in captivity and supplementary heating or lighting is generally unnecessary. It burrows readily, so give deep substrate and maintain humidity with a water dish and occasional misting. It is nervous and tends to stay hidden, but rarely bites. Exports from its home country are closed, so it is seldom traded and rarely bred.

Live insects such as crickets and roaches; large individuals also take small lizards and mice
Room temperature of 20-26 C is adequate and extra heating is generally unnecessary. Aim for 70-80% humidity using a permanent water dish and occasional watering of the substrate, while keeping ventilation good.
A large, enthusiastic burrower: use a spacious horizontal enclosure with deep substrate. Add cork bark as a log-like hide and leave any burrow it digs undisturbed.
Offer live insects such as crickets and roaches; large individuals also take small lizards and mice. Spiderlings feed well and grow fast.
Nervous and secretive, but it rarely bites. Besides kicking urticating setae it performs its distinctive spinning defence, striking with the spined hind legs. The venom is weak and no serious effects on humans are known.
The urticating setae are painful if they reach the eyes or nasal membranes, so keep your face away during maintenance. Exports from its home country are closed, so availability is limited.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
The ideal temperature for Colombian Giant Redleg is 20〜26℃. Recommended humidity is 70〜80%. Avoid sudden temperature changes and maintain a stable environment.
The average lifespan of Colombian Giant Redleg is Females up to about 20 years. With proper care and nutrition, they can live a long and healthy life.
Colombian Giant Redleg typically reaches 15-20cm leg span as an adult. Size may vary depending on care conditions and individual genetics.
Colombian Giant Redleg feeds on: Live insects such as crickets and roaches; large individuals also take small lizards and mice. Aim for a balanced diet with appropriate feeding frequency.
