Bilateral symmetry is a type of symmetry found in most animals in which appendages and organs of the body are paired and where the body can be divided into two equal halves by a section passing through midsagittal plane, e.g., Fish, Frog, Rat, Human beings, etc. It is an adaptation of motile life stRead more

Enterocoelom is a true coelom which develops as lateral pouches from the embryonic gut (archenteron), e.g., Echinodermata and Chordata. This. cavity is lined by cells of mesodermal origin.

Cnidoblasts or nematoblasts are stinging cells found in cnidaria or coelenterata. Each of them bears a stinging cell organelle called nematocyst which is used in offence, defense and attachment of the animal.

Choanocyte or collar cell is a unique cell type of porifers which contains a flagellum surrounded at its base by a thin cytoplasmic collar. This cell creates current and ingest food particles from water.
