Excellent climbers found in upper parts of clean and unaltered streams, often in fast water, clinging to boulders and rocks. Catches plant and animal matter in the running water with hairy modified pincers. Fed on by native and introduced fish species as well as crayfish and Tahitian prawns, as well as birds (black crowned night heron and wandering tattler). Lay eggs that hatch and flow down to the ocean. Larvae stays in the ocean for a few months and migrate to streams where they become adults. May travel as far upstream reaching 3,000 feet of elevation (Ref. 84067).
