How do Sharks identify their prey?

Sharks have electro reception, which is a keen sensitivity to electrical impulses. As fish swim around, their movement sends tiny electrical signals through the water. Sharks pick up on those signals as the water passes over a series of jelly-filled pores, which are sensory organs on their head. This electro reception allows sharks to snag prey with deadly accuracy, even in murky water.

Why do Sharks bite humans and leave them?

Why do Sharks bite humans and leave them?

Most sharks like to test their prey before entirely devouring them and that’s why most attacks on humans are just a bite or two. They are known to perform test biting with many familiar and unfamiliar objects in order to determine what kind of object it might be. Humans in any case are not appropriate prey for them as the sharks digestion is too slow to cope with the humans body high ratio of bone to muscle and fat. Even if they attack humans by mistake, a death occurs by loss of blood from the initial limb injury rather than from devouring.

Scorpions breathe in oxygen through four pairs of book lungs on the underside of their abdomen.

This provides an extensive surface for the exchange of oxygen and carbon dioxide with the surrounding air.

Why are Slugs used for research?

Why are Slugs used for research?

The sea slug Aplysia californica that can grow upto 16 inches long, has the biggest brain cells, or neurons, in the animal kingdom, at up to a millimetre long. These marine snails also have just 20,000 or neurons, compared with the 100 billion in people. The small numbers and large sizes of brain cells in sea slugs make the animals ideal for brain research.

There is a lubricant in the tongue which allows the muscles to slide at a lightning speed.

How can a Cockroach survive without its head?

How can a Cockroach survive without its head?

Cockroaches breathe through spiracles which are small openings on the skin. It is the spiracles and not the blood that carries oxygen to each cell of the body through a set of tubes called trachea. The brain does not c

ontrol the breathing through spiracles. Also, the cockroach does not have blood pressure and so cutting off the head does no lead to uncontrolled bleeding. So a cool temperature could allow a cockroach to last about a month without need for its head, as long as they are not infected by mould, bacteria or virus, which could kill them.
