combining form of Gr. ἐχῖνος, used (either in its original sense of ‘hedgehog’, denoting something prickly, or in that of ‘sea-urchin’, echinus) to form compounds in scientific use. eˈchinochrome, a brown or yellowish brown pigment found in some echinoderms; eˌchinocoˈccosis Path., disease caused by infection with tapeworms of the genus Echinococcus; hydatid disease; echinococcus |-ˈkɒkəs| Zool. [Gr. κόκκος seed-grain], a former genus of acephalocysts or hydatids, now known to be the scolex or higher larval form of a species of tapeworm, hence called Tænia Echinococcus (formerly T. nana); † eˈchinod, Obs., in 8 ekinod [Gr. ὀδ-ούς tooth], (see quot.); eˌchino-ˈencrinite: see encrinite; eˌchinoˈpluteus Zool., the free-swimming larval form of an echinoid.
1883C. A. MacMunn in Proc. Birmingham Philos. Soc. III. 380 *Echinochrome.—It is unfortunate that as one meets with new colouring-matters long names have to be invented to distinguish them from other colouring matters. This has been the case with the pigment which I have now to mention, and for which I propose the name of echinochrome. 1886Jrnl. R. Microsc. Soc. 48 Dr. C. A. MacMunn describes the spectroscopic or chemical characters of the blood of various worms and molluscs; one of the most interesting pigments which he has detected is that which he calls echinochrome..obtained from the perivisceral cavity of Strongylocentrotus lividus. 1912Jrnl. Chem. Soc. CII. i. 520 Echinochrome is probably held in the same way as chlorophyll is held in the plant cell. 1959Chambers's Encycl. III. 763/1 They [sc. naphthoquinones]..are apparently limited to sea-urchins. Many such species display conspicuous amounts of naphthoquinoid echinochromes in their thin skin and in the calcareous material of spines and shells, which thus assume red, purple, pink or greenish colours.
