Study Notes
Shark Adaptations and Habitats
- Sharks are adaptable and powerful predators, feeding on a wide variety of ocean organisms.
- Their adaptability allows for frequent movement, unlike animals with fixed homes. Sharks constantly swim to breathe.
- Sharks do not take care of their eggs; the young are independent upon hatching.
- Human activities are the greatest threat to sharks and their habitats.
Shark Habitats
- Sharks are marine fish, needing water to survive (mostly ocean water).
- Different shark species prefer different water types (temperature, depth, etc.).
- Sharks are found in many locations globally across various ocean conditions.
- Tropical waters (near the equator) have the most sharks due to consistently warm temperatures.
Shark Types in Different Habitats
- Whale sharks, nurse sharks, hammerhead sharks, and tiger sharks are common in tropical waters.
- Greenland sleeper sharks and black dogfish sharks are found in polar regions (despite cold temperatures).
- Polar sharks prey on fish in the winter and hunt seals/porpoises in warmer months when breaking through the ice.
- Bull sharks are an example of a species adaptable to both saltwater and freshwater.
- Glyphis sharks are a family that live mainly in freshwater rivers (in areas like Australia and New Guinea).
General Shark Characteristics
- Most sharks live in saltwater environments.
- A few species have been found in freshwater systems.
