Did u know that a shrimps heart is located on its head ? Yeah, it is true fact. Accually the heart is located on its thorax, its just after the head. The head & thorax is totally covered with a single exoskeleton only. Its because the shrimps thorax can be mistaken as still part of the shrimps head. Normally we see the shrimp divided only into 2 parts, the head and the tail, we see no thorax in it.

Every shrimp's heart has in its head
