Whales
and dolphins
Whales
are large, aquatic mammals that breathe air through either one or
two blowholes into their lungs. Toothed whales such as Killer Whales,
Sperm Whales, and Beluga Whales prey on fish, squid, or marine mammals
using echolocation. Baleen whales such as Humpback Whales, Gray
Whales and Minke Whales feed on tiny crustaceans, small fish and
plankton. They use their baleen to filter the food from the water
and are generally larger than toothed whales.
Belonging to the odontoceti or toothed whale cetacea, and family
Delphinidae, the largest family of the cetacean order, there are
26 living species of dolphins. Most species of dolphins feed mainly
on small schooling fish and squid although some species prey on
crabs, shrimps, and lobsters. Dolphins can be found in all oceans
and major seas around the world. Each species of dolphin has adapted
to life in their particular marine environment, allowing them to
specialize in catching and eating food specific to that area. |
