What is the similarity between sharks and ray-finned fishes?

The question is incomplete as it does not have the options which are:

A) The skin is typically covered by flattened bony scales.

B) They are equally able to exchange gases with the environment while stationary.

C) They are highly maneuverable due to their flexibility.

D) They have a lateral line that is sensitive to changes in water pressure.

E) A swim bladder helps control buoyancy.

D) They have a lateral line that is sensitive to changes in water pressure.

Explanation:

Both rays and sharks are the groups of fishes which are considered together in the category of the cartilaginous bones.

The rays are flattened fishes with the presence of the pectoral fins which are not found in the Sharks.

But the rays are considered the most closely related group of fish to the sharks as they both possess a unique sense organ called lateral line which detects the vibrations and the movement of water in the body.

Thus, Option-D is correct.

[ answer ]

foliated

[ explanation ]

foliation forms in a rock when pressure squeezes the rock together. the rock then has a design of many different color little lines. there are three types of foliated rock. the types are slate, schist, and gneiss. each type of foliated rock is different based on grain size and foliation characteristics. the lines appear when the rock has been under pressure.
