Abstract
Extracts of eye-stalks from several species of decapods, previously found to contain the chromatophore-activating principle, were injected into frog tadpoles and a variety of marine fishes to determine the range of effectiveness of the hormone and the response of the vertebrate chromatophores. Extracts from eye-stalks of white-adapted Crago vulgaris induced slight melanophore contraction in Anguilla rostrata and Limanda jerruginea, no response in Clupea harengus and Pollachius virens, moderate contraction in Myoxocephalus octodecimspinosus. Eye-stalk extracts from Pagurus longicarpus and Homarus americanus induced extreme melanophore contraction in Fundulus heteroclitus and extreme expansion in liana clamitans tadpoles.This publication has 2 references indexed in Scilit:
