How do nurse sharks eat?
Before we discuss what nurse sharks eat we need to learn how the nurse sharks eat, it is very unique. These sharks are kind of like vacuum cleaners, they have a powerful suction system that allows them to suck up their food. The food passes through several rows of teeth and then is fully digested in the stomach.
How do nurse sharks hunt?
Nurse sharks live in the Western Atlantic Ocean and the Eastern Pacific Ocean where they can be found near the shoreline hunting. Since they are nocturnal they often prey on small fish that are resting. They will also sometimes lay very still with their snout up to create a seemingly safe place for other sea life to hide, like crabs and clams. Then they surprise them with their powerful suction for dinner. Another hunting technique is to flip conch shells over, and with their suction and teeth, suck a snail out from its shell.
What do nurse sharks eat?
Besides snails, crabs, clams and small fish, nurse sharks also eat stingrays, squid, octopi, and sea urchins. Scientists have found algae and ground coral in their stomachs as well, but it is thought these were a part of the process of sucking up other nutritional food. Because they often hunt near the shoreline they sometimes get lucky and find a stash of fisherman’s bait (lucky for the sharks, not the fishermen!). In short, nurse sharks are opportunistic hunters that eat meat. Their primary meals are snails, crabs, clams, and small fish.
