Selachii to be a class or subclass that contains all the modern sharks and rays
Gina described a manta ray
Answer:
The correct answer is B. Batoidea
Explanation:
Batoidea is an order of cartilaginous fish which are commonly known as rays. Rays are morphologically different from sharks as their body is flattened and disk-like with very large pectoral fins.
In rays, mouth and gills are present on the underside of the body. They have five gills that are used for the diffusion of gases and are present on its ventral side but in sharks, gills are present on the side of their head.
Their flattened body helps them to hide in the sand of the ocean floor which prevents them to become prey to large predators like sharks and killer whales. Therefore the right answer is B. Batoidea
