Usually, many kinds of living beings live underwater. There are different types of fish families that survive underwater. Skates and Rays are the kinds of fishes that survive underwater from the Superorder Batoidea family. Although both Skates and Rays are from the same family, the functioning and structure are different.
Skates vs Rays
The main difference between Skates and Rays is that Skates are one of the types of fish that do not consist of projection tails. In contrast, Rays are one of the types of cartilaginous fishes that consists of spout tails. Skates had originated from the Rajidae family, where it refers to the whole order of the Rajiformes and Rays are the member in Superorder Batoidea.
Skates are one of the kinds of cartilaginous fishes that live underwater. Skates are members of Rajidae in the Superorder Batoidea family. These refer to the whole order of Rajiformes in Superorder Batoidea. Skates do not contain a spout tail where its tail is short and smooth without breaks. Skates protect themselves by depending on the sharp projections on the back and having a level tail.
Rays are the kind of cartilaginous fishes that appears rubbery. Rays are from the Superorder Batoidea family, which has interconnections with sharks. Usually, Rays can place with the sharks in the Chondrichthyes group. Rays will appear in kite structures consisting of double stinging spines. Rays can protect themselves with the help of these double stings.

| Difference | The structure is round and, it protects itself with sharp projections. | It appears in kite shape with a cane tail and, rays protect themselves with stinging spines. |
What are Skates?
Skates are one of the kinds of cartilaginous fishes that live underwater. Skates are from Rajidae, which is a sub-group in the Superorder Batoidea family. The skates will refer to the whole order of Rajiformes. Usually, there are 150 species in the Superorder Batoidea family where it mentions the Rajidae group. Skates, having a non-spout tail, and it does not contain spines. It carries a round structure and a sharp nose that connect with projections. These Skates can protect themselves from predators with the help of sharp-projection that consists of the back. The tail that appears without spouts helps in protection.
An individual will find the Skates in the world and, these will appear from tropical regions to Arctic oceans. The Skates live underwater where the depth is above 2700 meters. Skates will pop up in round shapes and triangle shapes with a heavy body. Skates consist of a spout tail with small fins at the end of the body.
Usually, skates live on their bellies in water and, these do not harm others. Many people will like to eat the Skates because they are harmless and contains clean flesh. It will be eatable before the expiration date because it is not good after the expiration. Skates like to eat small fish, crustaceans, and mollusks that are available underwater.
What are Rays?
Rays are the kind of cartilaginous fishes that lives underwater and, these are rubber in nature. Rays are the member of the Superorder Batoidea family. These are in kite-like structure and, it consists of a tail with projections. Rays contain double stinging spines. Usually, Rays had placed with the sharks in the Chondrichthyes group.
Rays will appear in kite structures consisting of double stinging spines. Rays can protect themselves with the help of these double stings. Rays include in the order of 534 species that live underwater. These are dislike bodies with a flattened structure having five openings in gills and, the mouth had placed on the underside of the body.
Rays are known as filter feeders when they consist of diet in oceans. These are the mysterious creatures that usually distinguish from sharks. There are 630 different types of rays that available in the Ocean. These 630 disparate creatures are from 18 families that had divided under scientific reasons. The Ray fishes will take from the Elasmobranch with Superorder rank. Stingrays, Electric Rays, Fiddler Rays, Sawfishes, Torpedo, Maculabatis, are some types of rays.
Stingrays use to eat the small animals which are available underwater. They use to eat clams, shrimp, worms, oysters available at the edge of the sand and water. An individual can eat stingrays and, these are harmless to health. Rays contain stings at the end of tails that are a bit harmful to humans.
Main Differences Between Skates and Rays
- Skates are the member of the Rajidae order in Superorder Batoidea, where Rays are from the Superorder Batoidea family.
- Skates are in round and triangle in a structure where Rays are available in kite shape structure.
- Skates are harmless, where the end-stings of the Rays are harmful.
- Skates protect themselves with sharp projections locate on their back. On the other hand, Rays preserve themselves with the double stinging spine connected with a tail.
- Skates like to eat the crustaceans, mollusks where the stingrays like to eat small creatures, clams, worms.
Conclusion
Skates are one of the kinds of cartilaginous fishes that live underwater. Skates are from Rajidae, which is a sub-group in the Superorder Batoidea family. The structure is round and, it protects itself with sharp projections.
Rays are the kind of cartilaginous fishes that lives underwater and, these are rubber in nature. Rays are the member of the Superorder Batoidea family. These are in kite-like structure and, it consists of a tail with projections.
