gill cleft

[ gil ]

Phonetic (Standard)IPA

noun

First recorded in 1885–90

These outgrowths are formed both by the lining of the gill-cleft and by the adjoining mesoblast.

An embryonic gill cleft behind the last present in the adult is found (Wyman, No. 54) in the embryo of Raja batis.

A gill-cleft has been noticed in Epicrium glutinosum (Mller), and in Cœcilia oxyura.

It is possible that the respiratory significance of the wall of the gill cleft has been secondarily acquired.
