Sharks and rays are in the same group of fish. Both have skeletons made out of cartilage instead of bone. Rays are flattened fish that look sort of like Frisbees. Sharks are more typically "fish-shape" with a large dorsal fin that sticks up above the water when they hunt. Sharks have rows of very sharp teeth. Rays have flat plates of crushing teeth because they eat clams and other mollusks that live in the sand.
yes
Dolphins are mammals. Sharks are fish. They are very different, though both are vertebrates.
There not really similar to each other because there both different sharks.
Stingrays primarily communicate through body language and behavior, such as using their pectoral fins and tails to signal aggression, submission, or courtship. They also emit electrical signals through specialized cells in their skin called electroreceptors, which can help them detect prey or predators in their environment. Additionally, some stingrays may use vocalizations or vibrations to communicate with each other.
No, sharks do not eat each other in their mother's stomachs.
Of course they can kill each other. Humans and sharks are enemies.
There are about 400 sharks in the ocean, and each shark has a different diet. Some sharks have eaten license plates, old tires, other sharks, and dogs. Since sharks have poor eyesight, they have swallowed very awkward objects.
Hammerhead Sharks are carnivorous predators. Their diet includes fish, squid, Octopus, Crustaceans and Sting Rays. Sting Rays are one of the hammerheads favorite prey species. Large Hammerhead species esp. the "Great Hammerhead" is known to feed on other hammerhead species as well. Hammerheads are also cannibalistic, they eat their own young ones.
There are many different species of sharks in our oceans. Each breed has a different expected length of life.
It is possible that sharks and orcas can be a mile from each other. Most of the time they will fight.
Stingrays primarily communicate through body language, such as changing their posture or movements. They also use special color patterns and bioelectrical signals emitted from their bodies to convey information to other stingrays. Additionally, they may use vocalizations, such as grunts and squeaks, to communicate with each other.
Depends. There are predatory sharks like the Great White, Tiger, and Bull Sharks which actively hunt and eat other varieties of shark. There are other species which will not actively hunt other species of sharks, but will feed on an already dead shark. However, there are sharks, like the Whale Shark which do not consume shark meat in any form, because their diet is entirely different.
