It is often amazing to see such a large creature move about with such grace. There are two types of whales toothed whales odontoceti and baleen whales mysticeti.
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.
Anatomy of whales. Toothed whales are predators that use their teeth to catch squid fish marine mammals etc. The plates are made out of fingernail like material called keratin. The holes on top of the whales head used for breathing.
It makes the baleen strong but still flexible. On the throat the gray whale has two to seven grooves of excess skin. The physical structures of organisms.
Baleen whales are the other suborder of the toothed whale species. Comparative anatomy of whales. 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. Baleen whales have a sieve like structure called baleen that catches huge amounts of tiny krill for nourishment. Its vertebral column undulates up and down in waves as it moves forward.
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. The front limbs of a whale are called flippers. The blue whale is the largest known animal to have ever lived far bigger than any of the dinosaurs.
The anatomy of a whale. Whales do the same thing as they swim showing their ancient terrestrial heritage. Whales have very good hearing and they are able to pass sound through the outer ear to the middle ear.
Whales consist of eight extant families. The thick insulating layer of fat of most marine mammals. Whales porpoises and dolphins are marine mammals and like all mammals they require oxygen.
Baleen whales dont have teeth. Comparative anatomy is the study of the similarities and differences in the anatomy of difference species. Toothed whales do feature teeth and this includes the sperm whale.
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. 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. Overlapping plates that hang from the sides of a humpback whales upper jaw.
They have rows of plates on the upper part of the jaw that look like the teeth on a comb. 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.
