Chitin, a white horny substance found in the exoskeleton of several invertebrate animals.
It would be soft but for the chitin, as the horny substance is called.
The whole outer shell of the insect is made of the horny chitin.
They are worked by powerful muscles, and are supported, like a fan, by ribs of chitin, which may be accompanied by air-tubes, blood-channels, and nerves.
The protein elements may be derived from reticulate granules and chitin from the glycogen reserves of the oocyte.
Alvinellids make complex chitin tube colonies on the flanks of black smoker chimneys.
Within marine chitin-containing organisms, the -type is abundant and chitosan can also be found.
