Nurse Shark- Predators and Threats, Behavior, Habitat…other information

Nurse Shark 

The nurse shark is a sizeable sized fish. The nurse shark’s scientific name seems like something Bilbo Baggins could have said to rally elves to his rescue: Ginglymostoma cirratum. The title is a mixture of Latin and Greek and means”curled, hinged mouth” to explain this shark’s slightly puckered look. It is easy to recognize due to its brownish color and round head. Since they’re inactive during the day, stay perfectly still, and aren’t targeted at fisheries throughout their range,  sharks are the most frequent shark species that SCUBA divers or snorkelers encounter reefs in their content. Historically, other sharks have been more prevalent, but significant fishing pressure has altered the community in several locations. Even though they seem benign while they sleep through the daytime, it’s unwise to pet sharks or tugs their tails. Some people are known to snack divers or swimmers who snore them alert, indeed as a method of self-defense. International nurse shark population trends are unknown; however, they’ve been depleted in certain areas due to overfishing. Nurse sharks are extremely simple to recognize. They reach quite large dimensions (10 feet/3 m), but they aren’t grayish in coloration, unlike many large shark species. Instead, they’re yellowish-brown.

Additionally, they have characteristically rounded heads, barbels they utilize to look for prey, and relatively tiny eyes. Throughout the daylight hours and during the night, they get far more lively and feed on seeds, beams, and invertebrates. They’re suction feeders and may create enough pressure to suck on the queen conch from its casing.
