pelvic gridles
An appendicular skeleton is composed of 126 bones of the appendages, and pectoral and pelvic girdles.
the pectoral has a shallow socket while the pelvic has a deep, secure socket. both for limb attachment.
caudal fin-the tail pectoral fin-the tail on the ventral side of the shark just above the pelvic fins pelvic fin- the underside fins that serve as the "arms" of the shark dorsal fin-the top fin that is usually seen on the surface of water in shark attacks
Its main function is to propel itself when swimming. This is different from sharks since they use their caudal fins as its main propulsion force.
I just had this on my homework.The answers for Pectoral are A. Flexibility, C. Lightweight, D. Shallow socket for limb attachment.For Pelvic, B. Massive, E. Deep, secure socket for limb attachment, F. Weight-bearing.Hope that helps!

Flexibility: pectoral girdle is more flexible-less ligaments, ball and socket joint is shallower Security: pelvic girdle is more secure, deeper socket. there are more dislocated shoulders than dislocated hips ability to bear weight: pelvic girdle can bear more weight-the pelvic girdle has bones that are fused (os coxa) and a joint with the sacrum. the pectoral girdle has a little bone called the clavicle connecting it to the body wall.
Massive weight
pectoral deals with either birds or our muscles, pelvic deals with your pelvis on a human
the pectoral has a shallow socket while the pelvic has a deep, secure socket. both for limb attachment.
A fish has several different types of fins. There are the pectoral fins, located beneath the operculum (gills). There is the pelvic fin, located at the bottom of the fish, below the pectoral fin. There is the anal fin, which i located behind the anus, and there is the dorsal fin as well. It is located on top of the fish.
The pectoral girdle is formed by the scapula, the humerus and the clavicle 3 bones in total
The paired fins (pectoral and pelvic) are the nearest things fish have to limbs.
Dorsal fin, pelvic, pectoral, anal and caudal.
