英语百科

Sclerite

The exoskeleton of a spiny lobster is made of a series of sclerites, connected by flexible joints.
Sclerites in clamps in Polyopisthocotylean monogeneans; various sclerites are in grey and black
The fossilized scleritome of Wiwaxia corrugata

A sclerite (Greek σκληρός, sklēros, meaning "hard") is a hardened body part. In various branches of biology the term is applied to various structures, but not as a rule to vertebrate anatomical features such as bones and teeth. Instead it refers most commonly to the hardened parts of arthropod exoskeletons and the internal spicules of invertebrates such as certain sponges and soft corals. In paleontology, a scleritome is the complete set of sclerites of an organism, often all that is known from fossil invertebrates.
