Anatomy Of Whales

Whales porpoises and dolphins are marine mammals and like all mammals they require oxygen. As whales began to swim by undulating the whole body other changes in the skeleton allowed their limbs to be used more for steering than for paddling.

Anatomy of whales. The plates are made out of fingernail like material called keratin. It makes the baleen strong but still flexible. The physical structures of organisms.

Baleen whales dont have teeth instead they have 130 to 180 baleen plates that hang down each side of their upper jaws like a fringy curtain. Baleen whales have a sieve like structure called baleen that catches huge amounts of tiny krill for nourishment. The front limbs of a whale are called flippers.

On the throat the gray whale has two to seven grooves of excess skin. It has long served as one of the main evidences for evolution due to the fact that it is very concrete and does not require extensive technology. Whales have very good hearing and they are able to pass sound through the outer ear to the middle ear.

It is often amazing to see such a large creature move about with such grace. The holes on top of the whales head used for breathing. Toothed whales are predators that use their teeth to catch squid fish marine mammals etc.

The blue whale is the largest known animal to have ever lived far bigger than any of the dinosaurs. Whales consist of eight extant families. The anatomy of a whale is designed to allow it to easily move through the water.

There are two primary whale suborders that are divided based on their physical. The largest creature ever to have lived with a tongue alone that can weigh as much as an elephant the blue whale rules the ocean. Baleen whales dont have teeth.

Whales do the same thing as they swim showing their ancient terrestrial heritage. Toothed whales do feature teeth and this includes the sperm whale. There are two types of whales toothed whales odontoceti and baleen whales mysticeti.

Baleen whales are the other suborder of the toothed whale species. Balaenopteridae the rorquals balaenidae right whales cetotheriidae the pygmy right whale eschrichtiidae the grey whale monodontidae belugas and narwhals physeteridae the sperm whale kogiidae the dwarf and pygmy sperm whale and ziphiidae the beaked whales. Comparative anatomy of whales.

They have rows of plates on the upper part of the jaw that look like the teeth on a comb. Comparative anatomy is the study of the similarities and differences in the anatomy of difference species.
