There are 88 species of whales, dolphins and porpoises, called “cetaceans” [si-tey-shuh n] which means marine mammal. There are two types of baleen and toothed whales. Mysticetes are whales that have no teeth but a kind of strainer hanging from the roof of their mouths. It lets water through but traps tasty things like krill and other small shrimp like fish.

The average age of killer whales is around 29 years, humpback whales are 45-50 years old, sperm whales are 60-70 years old, but blue whales can live 80-110 years! This is great considering the average for humans is around 82 years old. What could you do in 90 minutes? Well, the sperm whale stays underwater for 90 minutes, but for other whales that's too long, other whales can only stay underwater for 19-20 minutes. They can also dive to 1,000 feet (304.8 m). Oh my God, it's far away! Whaling The industrial practice of hunting and killing whales for their oil, meat, or whale bones. Before whaling became widespread in most of the world, three species of whales were nearly driven to extinction. Blue whales were listed as protected species in 1966, but were subsequently listed as endangered in 1986. Since then, blue whales have grown significantly. Scientists say there are around 10,000-25,000 left in the wild today. Humpback whales are also on the endangered list, with only 1,500 individuals. Humpback whales have slowly increased to around 15,000, meaning they are still endangered. The most endangered whale species is the North Atlantic right whale, there were only 500 of them left before the ban, these whales also mature very slowly and only give birth every 3 -5 years. Places like Japan, Norway and Iceland still haven't stopped hunting whales, killing 1,500 a year. Whaling was banned in late 1986. Feeding whales can eat up to 1.5 tons (1500 kg), or 8000 cheeseburgers. Food for whales can vary, depending on the type of whale: baleen whales or toothed whales. Mysticetes eat things like: Small fish Shrimp Plankton Crab Krill Toothed whales eat things like: Squid Sea lions Walruses Earless seals Seabirds Shark Most whales feed individually, but they can also sometimes use teamwork to get food. food, such as group feeding with a bubble net. , whales love to catch small fish. The collective feeding with the bubble net begins with a synchronized dive, some whales pass under the school of fish, in order to bring them back to the surface. Then the bubble specialist blows a large wall of bubbles that surrounds the fish like a net. Then the designated vocalizer begins to emit an almost definite sound, terrifying the fish and causing them to rise to the surface. Then, after all this, they have an absolute party! Reproduction Female whales remain pregnant for a year and when they give birth the calf is approximately 3.75-4.5 meters long. After the calf is born, they stay with the mother for about a year, the mothers teach the calves about the world, how to migrate thousands of miles, who to trust and who to fear, what.
