We have moved all content for this concept to for better organization. A chiton’s shell consists of eight separate plates that overlap to form a shell like a coat of armour along the upper surface of its flat oval body. The name comes from the characteristic presence of 8plates called valves that are overlapping and attached to a part of the mantle called girdle.

The Solenogastres (less often referred to as Neomeniomorpha), common name the solenogasters, are one subclass of small, worm-like, shell-less molluscs (Aplacophora), the other subclass being the Caudofoveata (Chaetodermomorpha). Since that first recent species (Neopilina galathaea) was discovered, around 20 other species have been identified.One reason for having evaded detection for so long is that they are generally found in the deep ocean. POPPE-IMAGES™ has the aim to document the Marine Life in the Philippines. Animal: The animal body is composed of a head, a mantle and a large flattened foot. With the exception of a ventral groove, the mantle covers the entire body.
