Tarantula - Trinidad Chevron
The Trinidad chevron tarantula, is an arboreal species of spider in the family Theraphosidae, endemic to Trinidad. Its venom is the source of psalmotoxin and vanillotoxin which are classified as inhibitor cystine knot proteins. Psalmotoxin may be of therapeutic use in patients suffering from a stroke. The female has chevron-shaped dark markings on the abdomen and her color varies through shades of green and brown with characteristic red or orange flashes on the legs. The mature male is sexually dimorphic, colored a more uniform grey or brown, the body appearing smaller in comparison to the diagonal leg span, reaching five inches on average. Males can reach maturity in as short as one years time. The female is very large and fast growing, reaching seven inches in leg span. It feeds readily and makes an attractive display animal, being fairly active when given correct housing conditions. Spiderlings of this species are very opportunistic and will usually create a home in a small crevice hidden with a silken blanket covered in soil.
