Rectum ** This is the short end of the digestive tract between the intestine and the cesspool. The rectum stores solid waste. Spleen ** Located caudal in the stomach and just proximal (in front of) the IUD. This organ does not belong to the digestive tract, but is connected to the circulatory system.
The lectern is the pointed muzzle in front. This tapered tip in the front helps overcome water resistance while swimming. The eyes are prominent in sharks and look very similar to human eyes. A transparent cornea covers and protects the eye.
Definition of the openings of the spiracles just behind the eyes of all rays and some sharks. These are modified gill slits that allow the fish to absorb oxygen-rich water. Spirals help a shark breathe when it is on the ocean floor or even just ■■■■■■ in the sand.
As with humans, the great white shark cerebellum is responsible for muscle coordination, especially in response to sensory input. So when a great white shark leaps in response to a sudden loud noise, or is faced with a new vibration or an attractive electrical signal, it obeys the signals of the cerebellum.
Crustacean pedestal In the case of a crustacean, the lectern is the projection of the animal shield that extends before the eyes. Its function would be to protect the lobster’s eyes, especially when two lobsters come into conflict.
Helps overcome water resistance while swimming. The ability to penetrate water through the gills allows the shark or land fighter to have a greater exchange of oxygen and carbon dioxide.
Shark noses are only used to smell the environment, not to breathe. Sharks breathe through their gills. People use their noses to breathe and smell.
With each movement, the snout absorbs more water so that the shark can analyze it and the shark can tell if it is coming from the right or left nose. It helps them understand how to swim. The shark can work so well because it has nothing else to do. Sharks smell only with their nose.
The liver is rich in oil, which stores energy for the shark. Low specific gravity oils cause shark to have limited buoyancy.
On the back of the pelvic fins are the male reproductive organs, called clamps, which transfer sperm to the female.
Unlike fish, which have a gas-filled swim bladder that keeps them afloat in the water, sharks rely on a large fatty liver for some buoyancy. The oil in the liver is lighter than water and gives the shark some float, but it is still heavier than water and sinks when it is not actively swimming.
The beak (or snout) of a dolphin / whale is called a lectern and can also refer to other unrelated structures in other animal groups. In particular, it is not needed. Simple, it follows the shape of your mouth and holds your teeth in place.
Many call this long nose, formed by the lower and upper jaw, beak or snout, but the real name is actually a lectern, as Dolphin Anatomy Terminology Man pointed out.
Shark skin looks like sandpaper. It is made up of small tooth-like structures called placoid scales, also called dermal denticles. These scales point towards the tail and help reduce friction from the surrounding water as the shark swims.
In front of each dorsal fin are two large pointed and slightly poisonous vertebrae. Spiny Dogfish uses its back defensively by crouching and hitting an enemy. Dogfish’s skin is rough and covered with a scaly, tooth-shaped surface called a cutaneous dent.
Since sharks have no bones, they rely on cuticle teeth covering their skin to help them stay fit. The texture of their skin is rough because it has small, tooth-like scales called dermal denticles.
