How are sharks and rays different?

Body shape:

- Sharks have a more streamlined body shape, while rays have a flattened, wing-like body shape.

Dorsal fins:

- Sharks typically have a single dorsal fin, while rays may have multiple dorsal fins.

Tail fins:

- Sharks have a caudal (tail) fin that is divided into two lobes, with the upper lobe being larger than the lower lobe. Rays have a caudal fin that is not divided into lobes and often has a whip-like shape.

Spiracle:

- Sharks have a spiracle, which is a small opening behind each eye that helps to bring water to the gills. Rays lack spiracles.

Teeth:

-Sharks have multiple rows of sharp, pointed teeth, while rays have small, blunt teeth that are used for crushing prey.

Skin:

- Sharks have tough, rough skin due to the presence of dermal denticles, which are small, tooth-like scales. Rays have smooth skin that lacks dermal denticles.

Habitat:

- Sharks can be found in a wide range of habitats, including the open ocean, coastal waters, and even freshwater environments. Rays are mostly marine and are commonly found in shallow coastal waters.
