1| Cute amphibian: sea lion
The sea lion looks fat, fat and very cute. A male California sea lion weighs an average of about 300 kg (660 lb) while a female sea lion weighs 100 kg (220 lb). The largest sea lion is the Steller sea lion, which weighs 1,000 kg (2,200 lb) and can grow up to 3 m in length. Sea lions eat 5-8% of their body weight with a single meal.
California sea lions are very sociable animals – they often gather in groups in their favorite spots on land or swim in groups on the ocean and are called “rafts”. Sometimes they see dolphins or jump out of the water, presumably to speed up the swim. Some people also saw sea lions surf and the waves break. California sea lions are very sociable creatures. In a large social group made up of hundreds of sea lions, they can often be heard barking like dogs. When not wandering beaches and rocky shores, California sea lions hunt at sea for several days.
2| Habits of sea lions
The special body design enables them to live an amphibious life. In the water, the sea lion’s body is streamlined like a torpedo. The front fins, like wings, can reach speeds of 25 km / h. When diving, the sea lion’s heart rate can slow down by 80% and direct blood to the heart and central nervous system. And sea lions can store oxygen in their muscles better than any land mammal. Sea lions have two cute “little ears”. Although the sea lion’s ear flaps are small, they can hear very well above and below the surface of the water. His ears are also valves that close underwater. Sea lions often make noises underwater and can easily locate the source of the sound. On land, its front and rear fins can rotate under its body, allowing it to walk on all fours. Twisting a thick body on land makes people laugh very easily.
When they’re in groups on the beach, people get very jealous. They are lazy and easy-going, and the whole group has similar habits. Sleeping on the beach is not blamed. If you want to eat fish, all you have to do is go into the water and catch the fish easily.
They are all-rounders, eat herring, grouper, anchovies and other fish, krill and invertebrates such as cuttlefish and squid. If necessary, they can dive to a depth of 1,000 feet. In recent years, many sea lions have died from the destruction of the marine environment from pollution, eating plastic, or non-degradable products. The natural habitat of the sea lions has also been destroyed. It is the responsibility of humans to protect the sea lions’ living environment.
