Study Notes
Shark Characteristics
- Sharks are set apart from other fish by their cartilaginous skeleton, which makes them lighter and more flexible.
Locating Prey
- The adaptation that helps sharks locate prey even in murky waters is the ampullae of Lorenzini, which are specialized electroreceptors that can detect the electrical signals produced by other animals.
Sensory System
- Sharks have a unique sensory system called the "lateral line" that allows them to detect changes in pressure and vibrations in the water.
Shark Traits
- One true statement about sharks is that they are apex predators, which means they have no natural predators in the wild.
Agility and Hunting
- The adaptation that makes sharks more agile hunters is their streamlined, torpedo-shaped bodies, which enable them to swim quickly and make sharp turns.
