How does a Python eat?

How does a Python eat? 

The jaws of a python are not like a human’s jaws. Humans cannot open their mouth very wide, but a python can.

The jaws of a python are extremely flexible because they are not fused together and they are not connected to the back of its mouth. 

A python can open its jaws so wide that it can eat a medium-sized animal whole – such as a deer, antelope, pig, cat, or dog.

Common Marine Hermit Crab

The Common Marine Hermit Crab (Pagurus bernhardus) is a saltwater aquatic decapod (10-armed) crustacean. It is also known as the Soldier Crab.

Hermit crabs include the Marine Hermit Crab, which lives in saltwater, and the Land Hermit Crab, which is terrestrial in tropical regions.

The Common Marine Hermit Crab is a crab inside a shell – its mobile home. It finds empty mollusc shells to live in. It has a long soft body – not like land crabs which have a hard exo-skeleton – which is why it looks for a hard shell to protect it. It can put its whole body inside the shell. As it grows, it looks for larger shells.

The Common Marine Hermit Crab has a spirally-curved soft body (abdomen) with a columella on the tip, which is used to hold onto the shell it occupies. It has 10 appendages (legs, called pereiopods), but two of them are claws, called nippers, pinchers, or chelipeds. Its large black compound eyes are at the end of an eyestalk. It has gills to breathe (like fish).

The Undulate Ray has a flat disc-shape body, with a triangle-shaped front part (head) and nearly-round body. It is not perfectly round because it has elongated sides. It has a long tapering tail with two small dorsal fins at the end with two thorns between them. They are barbless.

It has bulging eyes that are close together and face the front. Its mouth is on its underside and is small. It has five pairs of small gills which enable it to breath underwater. It is light-brown or grey with dark bands on its tail and dark spots on its body. Its has a creamy-white underbelly.

Oryx Teeth

The Oryx (Oryx sp) is an antelope, which is a hoofed ruminant mammal.

Ruminants have well-developed molar teeth, which grind plant-based food – called the cud – into food balls.

The Oryx, like all antelopes, has no upper incisors. Instead, it has a hard, upper gum pad. The lower incisors use the gum pad to bite and tear grass stems and leaves.

Carnivore Teeth and Herbivore Teeth

f&m Leave a comment

What’s the difference between the teeth of carnivores and the teeth of herbivores?

 

Carnivores – or carnivorous animals – eat the flesh (meat) of other animals.

Carnivores have specialized teeth for killing an animal and tearing its raw flesh. These long, sharp teeth are called canine teeth or carnassial teeth. Some carnassial teeth are so strong that they can cut through bone.

Carnivores also have powerful jaws, a short nose, a strong neck, and powerful legs. This is because carnivores need to actively hunt and catch their prey, so they must be fast and strong.
