Shark Senses |
| Sharks and rays have evolved a range of extraordinary senses to detect their prey: |
- They have an acute sense of hearing - using an inner ear and lateral-line system to detect vibrations.
- Their nostrils are used for smelling only, not breathing - 'Lemon sharks can detect a concentration of one part tuna in 25 million parts of seawater.'
- Some sharks have acute eyesight and can almost certainly see in colour - The lemon shark can see in the dark ten times better than humans.
- Sharks have a unique bio-electrical sensory system - sharks and rays can detect the weak electric fields produced by all live animals, even if they are buried in sand.
