Question

would not be found in sharks.

	A.	sacral vertebrae
	B.	splanchnocranium
	C.	vertebrae
	D.	both pectoral and pelvic girdles
	E.	chondrocranium

Answer 1

Sacral vertebrae is not present in sharks.

The splanchnocranium represents the visceral skeleton of the shark and consists of the seven visceral arches.

In the White Shark, the total number of vertebrae ranges from 170 to 187.

the pectoral girdle of sharks is a single rigid element covered entirely by muscles and skin. The pelvic girdle of the elasmobranch fishes (e.g., sharks,) consists of either a curved cartilaginous structure called the puboischial bar or a pair of bars lying transversely in the ventral part of the body anterior to the cloaca; projecting dorsally on each side is a so-called iliac process.

Chondrocranium is present in sharks.
