The zebra shark feeds primarily on shelled molluscs, though it also takes crabs, lobster,crayfish shrimps, small fish.
This is a zebra shark, in Thailand also known as leopard shark. During the day, zebra sharks are sluggish and usually found resting on the sea bottom, sometimes using their pectoral fins to prop up the front part of their bodies and facing into the current with their mouths open to facilitate respration. Reef channels are favored resting spots, since the tightened space yields faster, more oxygenated water. They become more active at night or when food becomes available. Zebra sharks are strong and agile swimmers, propelling themselves with pronounced anguilliform (eel-like) undulations of the body and tail. In a steady current, they have been seen hovering in place with sinuous waves of their tails.

Simple Tips for Preventing Seasickness (Divers Alert Network)Seasickness is a condition individuals may experience when on a moving platform. It involves a general feeling of illness, dizziness, nausea and vomiting. It is also called motion sickness. Passive motions disturb fluid movement within the labyrinth and affects one’s sense of balance and equilibrium. It is exaggerated when the brain receives conflicting messages delivered from the eyes, muscles and joint sensors (proprioceptors). In a closed room, the view indicates that the surroundings are still, while the signals from the labyrinth indicate that the body is moving. Motion sickness can occur when traveling on a ship, plane, train, bus or car. Some people are more sensitive than others, but if the motion stimuli are strong and the exposure lasts long enough, nearly all individuals will experience it. Symptoms The symptoms of motion sickness include dizziness, sweating, nausea, vomiting and a general feeling of discomfort or illness. Symptoms can strike suddenly and progress from simply not feeling well to cold sweats, dizziness and vomiting. Motion sickness is more common in women and in children 2-12 years old. Individuals who suffer from migraine headaches are also more prone to motion sickness. Motion sickness lasts as long as the motion lasts. Once the motion stops, symptoms quickly subside. Some people feel “sea legs” after a long sojourn at sea. Prevention and Management If you know you have motion sickness or might be prone to it, consider this advice:
Treatment
Motion sickness can be treated with over-the-counter and prescription drug products.
