Among marine life, there are about 90 species of cetaceans in existence, many of which are large cetaceans, but they also have a more docile personality, and they also interact with humans very friendly, generally not attacking humans. On foreign social networking sites, some people shared how small the kayak looked in the contrast of a huge whale, and the whale was very friendly to push the kayak, which made people surprised and scared.
When you see the giant whale using its wings to push the small kayak, very kind to help the kayakers, but netizens feel that the giant whale is so interactive, where do the people on the kayak dare to move. In fact, kayakers are not afraid of these giant whales, these whales do not attack people, because they are deliberately kayaking out, can see the giant whales closer, which is also a way to watch whales.
From the appearance of these giant whales, it should belong to a kind of southern right whale, the southern right whale is indeed a huge cetacean, these cetaceans are generally 15-18 meters long, weighing 47-80 tons, while the southern right whale personality is also relatively docile, and will not show aggression, plus their swimming speed is also relatively slow, generally slow swimming in the water, so it is often found that this whale and whale watching tourists interaction.
In the marine food chain, southern right whales feed mainly on plankton, small plankton crustaceans, small molluscs, etc., so where the plankton population is more abundant, the southern right whale population will also migrate with food, migrate north in winter and spring, and migrate to the southern latitudes of the southern hemisphere in the summer months.
Cetaceans do not belong to fish, but belong to aquatic mammals, but the shape and habits of cetaceans have been significantly different from other mammals, this is because cetaceans in order to adapt to the underwater environment, their forelimbs evolved into fins, hindlimbs degenerated, and gave birth to horizontal tail fins, but also need to surface to breathe air, can not live in the water all the time, so the nostrils of cetaceans moved to the top of the head, every once in a while the nostrils are exposed to the surface of the water to replace oxygen.
Right whales usually refer to the North Atlantic backless whale, north Pacific backless whale and south back whale three types of large whale collective, right whale members are basically not afraid of people, of which the south right whale is large, slow swimming, fat thick, but also curious, often take the initiative to approach the boat, unsuspecting, if you encounter a whaling boat, it is easy to let the south right whale be fished and killed.
