Common names for turtle feet: Buddha's Hand Shell, Stone Snail, Dog Claw Snail, Turtle Feet, Chicken Crown Shell, Chicken Feet, Chicken Feet, Guanyin Palm. The body is divided into a head and a handle, generally 2-3 centimeters wide and 3-5 centimeters high. The head is light yellow and green in color. The handle is soft and brown or yellow brown in color, with small calcareous scales arranged tightly on the surface. The largest individual has a head width of up to 44 millimeters, a height of 27 millimeters, a handle width of 25 millimeters, and a length of 15 millimeters. The head is flattened on the side, and the shell chamber is formed by 8 shell plates including the rib plate, back plate, upper side plate, peak plate, and kiss plate. The base has a row (21-31) of small side plates that rotate.

Trilobites are arthropods belonging to the order Tetraodontiformes in the phylum Arthropoda. The body is divided into three parts: head, chest, and abdomen; There is a carapace on the back, which is longitudinally divided into three pieces. The head is covered with a hard shell, called a cephalothorax; The central raised part of the head armor is called the head saddle, and the shape and size of the head saddle vary greatly depending on the type; The anterior part of the head saddle is the skull, on which there are eyes; There are also shells wrapped around the abdomen and tail. Named after the longitudinal division of the carapace on the back into three pieces. Widely distributed in ancient oceans, fossils are found on all continents today. I like to live in warm shallow sea areas and feed on algae, protozoa, and other organisms.
