Description of a blue shark

Biology
1 answer:
Westkost [7]3 years ago
5 0

The aerodynamic shape and lightness of the blue shark body allow it to move “elegantly” across the oceans. It exhibits countershading like many other sharks. The upper part is an indigo blue tone while the ventral and the sides are white.

It has a long caudal heterocercal fin. The second dorsal fin measures almost half the size of the first and its pectoral fins are unusually long compared to other sharks. Its eyes are large, its teeth are triangular, and it has a conical snout.

It reaches a length ranging from 3.8 to 4 meters and weighs about 240 kilograms. This species presents slight sexual dimorphism since the female tends to measure little more than 1 meter in comparison with the male.

How do plants regulate water loss due to transpiration?
olga nikolaevna [1]
Stomata are tiny pores present in the leaf that allows gas exchange and is where water vapour leaves plants and carbon dioxide enters. Special cells called guard cells present in the stomata, control each pore's opening or closing. When stomata are open, transpiration rates increase; when they are closed, transpiration rates decrease.

It is composed of two main layers,

  • epicuticle ⇒ outermost layer
  • procuticle ⇒ inner layer

The cuticle is mainly made of chitin, and its function is to protect the organism's body and avoid dehydration.

Because it avoids dehydration it is believed that arthropods had such an evolutive and adaptative successful in their transition from water to the land.

The cuticle also provides support to the body and a muscle attachment surface.
