Microcotyle centropristis

Microcotyle centropristis has the general morphology of all species of Microcotyle, with a symmetrical body, comprising an anterior part which contains most organs and a posterior part called the haptor. The short haptor is symmetrical, and bears clamps, arranged as two rows, one on each side. The clamps of the haptor attach the animal to the gill of the fish. There are also two relatively large and round buccal suckers provided with a row of minute teeth and located at the anterior extremity. The digestive organs include an anterior, terminal mouth, a muscular pharynx, a long oesophagus and a posterior intestine with two lateral branches provided with numerous secondary branches. Each adult contains male and female reproductive organs. The reproductive organs include an anterior genital atrium, armed with numerous fine sharply pointed spines directed inward and upward, a medio-dorsal vagina, a single ovary indistinctly outlined and a number of testes which are posterior to the ovary. The eggs have a very short spur-like processes at each end, instead of filaments, or are rounded at the ends.^[3]

The host-type is the black seabass Centropristis striata (Serranidae). The type-locality is the New York fish market.^[3]
