TL;DR
Only two teleosts (milkfish and rainbow trout) showed hydrosmotic activity comparable with that of Gillichthys; the other species showed essentially no detectable activity on the isolated urinary bladder of the Hawaiian toad Budo marinus.
Abstract
Sixteen species of fishes were examined for urophysial hydrosomotic activity comparable to that present in the caudal neurosecretory system of the globiid teleost Gillichthys mirabilis. Only two teleosts (milkfish and rainbow trout) showed hydrosmotic activity comparable with that of Gillichthys; the other species showed essentially no detectable activity on the isolated urinary bladder of the Hawaiian toad Budo marinus.
