Trechalea
Trechalea is a genus of semi-aquatic spiders in the family Trechaleidae, distributed from the southern United States through Central and South America to northern Argentina. The genus was established by Thorell in 1869, replacing the preoccupied name Triclaria. At least one species, T. extensa, exhibits specialized diving behavior as an antipredator tactic, using plastron respiration to remain submerged for over 30 minutes.
