Chiton anatomy. The decrease in temperature experienced around fall will trigger within a newly settled organism the growth of the gonads. The male releases sperm into the water while the female releases eggs either individually or in a long string. A comparatively simple body plan is found with a straight line arrangement of the visceral organs somewhat like that of the monoplacophoran gastropod neopilina galatheae mentioned earlier see shell classes.
All the living species are in the subclass neoloricata and so may be called loricates. 500 bc through the hellenistic period 32330 bc. Black katy chitons are primarily dioecious diploid organisms.

In most cases fertilization takes place either in the surrounding water or in the mantle cavity of the female. Chitons have separate sexes and fertilization is usually external. The anatomy of chitons is comparatively simple and with no evidence of torsion.
They are found in shallow tropical waters. Inside the aesthetes cuticular eyes can be developed. Usually they are also branched to several micro aesthetes.
In the dorsal shell plates of a chiton there are the so called aesthetes. Chiton seems a small turtle. They have a single shell that sticks to rocks like a limpet.
There are actually 8 shells which are overlaped each other under the muscular tissue. The hatching stage is a trochophore larva but no veliger develops from it. Some species brood the young in the mantle cavity.
Those are mechanical sense organs which can detect water movements. Chiton chitons are primitive marine molluscs in the class polyplacophora formerly the class amphineura.
