Sharks have been part of the seas for more than 400 million years. They inhabit every ocean and play a vital role in maintaining the health of marine ecosystems.
- Sharks range from the world’s largest fish, the whale shark, to the 15cm spined pygmy shark.
- Sharks have 7 senses: hearing, sight, smell (several miles in range), touch, taste, electrosense, and the lateral line and pit organs that pick up weak vibrations.
- Sharks are capable of learning and display social behavior. Their brain to body ratio is within the range of birds and mammals.
- Sharks migrate long distances to find food and to reproduce.
- Shark skin is covered with “denticles”, tiny tooth-like projections. This is now copied for swim suits by Speedo, for submarines by the US Navy and for the space shuttle by NASA.
- Sharks are utilized for meat, cartilage and fins and are a critical food source for many developing countries.
- Sharks are slow growing and long lived. Females reproduce late in life, and have few offspring making it slow from them to recover from declines.
