Characteristics and Behavior:

The nurse shark is a medium-sized, bottom-dwelling shark with a rounded snout and barbels (whisker-like sensory organs) on their nasal flaps. They have a uniform, brownish-gray or yellowish-brown coloration and lack prominent markings or spots. Nurse Sharks are nocturnal, meaning they are most active at night, but can often be seen resting on the ocean floor or cuddling with other nurse sharks during the day.

Fun Facts:

  1. Peaceful Predators: Nurse sharks are generally considered docile and non-aggressive toward humans. They are opportunistic feeders, primarily consuming small fish, crustaceans, and invertebrates.
  2. Nursing Behavior: The name "nurse shark" is derived from their feeding behavior. They create a strong suction by opening and closing their mouths to draw in prey from crevices and the sea floor, resembling a nursing action.
  3. Rasping Teeth: Nurse sharks have small, numerous teeth used for grasping and grinding prey. Their teeth are adapted for crushing the shells of crustaceans, making them proficient scavengers.
