Whales

Whales are found in all the oceans of the world. Whales prefer cooler and deeper waters so they are most numerous in the Arctic and the Antarctica.

Whales are the largest predator known, they eat nearly 3 to 4 percent of their body weight. Not only every aquatic life is a prey, they are known to eat polar bears, reptiles and even a moose.

Whales hunt as a team in pods for food. They are classfied as Resident pods, transient pods and Offshore pods

Resident pods are the most commonly sighted of the three populations in the coastal waters of the northeast Pacific. Residents' diet consists primarily of fish and sometimes squid, and they live in complex and cohesive family groups called pods.

Transient pods consists almost exclusively of marine mammals and they do not eat fish.Transients generally travel in small groups, usually of two to six animals, and have less persistent family bonds than residents.

Offshore pods as their name suggests, they travel far from shore and feed primarily on schooling fish. Offshores typically congregate in groups of 20–75, with occasional sightings of larger groups of up to 200.

Whales are mammals and not a fish, classified under Cetaceans; split in two groups depending on whether they have teeth or not viz. Odontoceti and Mysticeti. They breath air like mammals and to do so, they return to the surface at regular intervals.

Whales give birth to their young ones, who stay with the mother for over a year and feed on milk produced by the mother. They are also warm blooded and have a skeleton structure, though modified to suit the aquatic life, similar to us.
