Do sharks sleep in caves?

Different sharks breathe in different ways, and this influences how they rest. Some species are thought to 'sleep swim', others lie stationary on the seafloor, and some snuggle up in groups or someplace out of sight where it's safe to rest such as in a cave or in the sand.

Do blind sharks live in caves?

Habitat. The Blind Shark lives in shallow coastal waters. Juveniles are often seen in high-energy surge zones, whereas adults are usually seen during the day in caves and under ledges.

Do tiger sharks live in caves?

What would happen if sharks disappeared?

Without sharks as apex predators, the entire ocean ecosystem could fall out of balance. They not only maintain the species below them in the food chain, but also indirectly maintain seagrass and coral reef habitats.

Do sharks ever stop swimming and sleep?

While some species of sharks do need to swim constantly, this is not true for all sharks. Some sharks such as the nurse shark have spiracles that force water across their gills allowing for stationary rest. Sharks do not sleep like humans do, but instead have active and restful periods.

What's the deepest a shark can go?

Sharks can be found on the shallow waters and dive deep until around 10,000 feet, as concluded by many scientists. This is confirmed by the study done by Dr. Priede et al. in 2006 when they studied the deep oceans for over 20 years.

What kind of shark was found in Kentucky cave?

Experts believe that the fossils are from a range of shark species (probably over 40 species) including one that was bigger than the great white shark of today.
