This creature, called the "sea rabbit," is actually a type of sea slug, but the sea slugs are just a common name for the post-gill suborder, and their morphological differences are no less than the difference between you and your distant relatives of 18,000 miles.
Such fancy-looking gills belong to the nudibranch, and these flower-like things on the back are its bare gills, and these gorgeous colors also indicate their toxicity, and when in danger, they will spray purple juice to kill small animals or avoid predators. Here's the point: it's poisonous and can't be eaten.
The other is the order dùn, where the two rabbit ears are actually their antennae, which govern the senses of touch and smell. They are close relatives of snail conchs, but the shell has degenerated into a small inner shell that grows into flesh, and the gastropods are turned upwards. Like snails, they are hermaphrodite and are quite stimulating to reproduce, usually calling three or five friends, or directly coming to a dozen in a string for mating.
The sea hare sandwiched in the middle is male to the front and female to the back. After a few hours, or even days of fighting, all but the last one was pregnant. So pedaling two boats is a thing, people directly step on the fleet, the next protagonist of the Sea King is not a sea hare, I will not watch.
What's more, some sea slugs have male organs that are "used and lost", which automatically fall off after completing multi-person exercise, and then grow a new one within a day like squeezed toothpaste for the next time.
Although sea slugs cannot be eaten, the eggs they lay are edible, which is what coastal residents call "sea noodles", which is called "haisuo noodles" in Japan. Usually, what color they eat seaweed, the egg band they lay is what color. China usually eats the egg bands laid by the blue-spotted sea rabbits cultivated by Fujian people, and it is said that it has a smell of kelp when eaten.

This cute little cute who paces slowly on the bottom of the sea is called "sea pig" (scientific name: scotoplanes), in fact it is neither a fish nor a pig, but a member of the echinoderm sea cucumber family, that is, it also has a cloaca, and it has to do everything you can imagine with the only hole in the whole body... It usually survives by ingesting organic matter and whale carcasses from deep-sea mud.
The legs on both sides of the sea pig's body are actually liquid filter tubes that can crawl forward by controlling the pressure of body fluids, and the tentacle-like things in front of the circle are actually tube feet, which can both crawl and detect food.
If you see a small toy hanging from the crotch of a sea pig, it should be the cub of the king crab, and when the surrounding seabed is relatively barren, they can only hang there to avoid predators.
3. This seemingly headless little guy is actually a gloster canary selected by an Old British Lady in 1920.
Look at this fluffy hair volume, retro style, melancholy British temperament, the style is like the beatles official launch of peripheral products. In addition to the pot lid of one water, their voices are slightly larger than other canaries, and they should be able to make a british band when they put together four of them.
Compared to other pet birds, it is also very worry-free to raise: it is not destructive, it does not need too much toy food, and it does not need to be cared for and soothed, and it is an artist throughout the day. It's no wonder it's become Britain's most popular canary, and I don't dare say I've heard of the Beatles without raising one. At the same time, it is also a meme that Americans love to use every day, and I have to say that this untamed head shape is indeed similar to Teacher Chuan.
It seems to be very different from the image of the canary we remember, but in fact, the current caged canary was originally artificially bred from wild canaries. They were first brought back to Europe by Spanish sailors of the Age of Discovery, when merchants deliberately created shortages in order to speculate in prices, and only male birds were sold, which were generally only affordable to European royalty and nobility.
However, now the canary has become a very popular caged bird, which can be roughly divided into three categories from the perspective of ornamental purposes:
One is the "color class", such as the most common golden canary bred by inhibiting the melanin gene, and the others are cardinal, white and colored woolly goldfinch;
The other is the "form class", such as the Chuan teacher just now, and this kind of northern dutch curled canary like a feather duster; the third is the "singing class", which as the name suggests is a very good sound.

This colorful ass is a mountain fish, and The Rafich who lifts Simba in "The Lion King" is a mountain fish. Originally, the mountain fish is a genus of baboons, but in recent years it has become independent, and there are currently two kinds of animals in the genus: mountain fish and ghost baboons, which are basically the difference between color and black and white in appearance.
Many children who grew up in mountainous areas have heard the legend of mountain fish since they were young, what mountain monkeys, mountain gods, and mountain spirits. There is also a cry-stopping artifact called "Legend of the Mountain Fish Ghost", which says that the mountain ghost will follow the cries of children to the house, and then take them away and eat them.
There is also a folk saying that "it is better to meet the jackal than to meet the mountain fish", that is, the mountain fish is the mountain king, dare to fight with the beast, can scare off the lion and leopard. This also corresponds to the record in the Classic of Mountains and Seas, saying that it is "infinitely powerful, capable of fighting tigers and leopards, the most ferocious things." The mountain fish is indeed the largest surviving monkey primate. Some people say no, shouldn't the biggest one be a gorilla? Here, the gorilla is indeed the largest of all primates, but it is a human family, and the largest of the monkey family is the mountain fish. The leading old male monkeys are more brave and belligerent, and can lead the team to fight hard with the leopard, but the leopard is also a chicken thief, and will pick females and cubs to sneak attack.
In general, the brighter the color of the face and buttocks of males, the higher the status and the more popular they are with females. They can secrete a higher testosterone than other males, making themselves extraordinarily eye-catching, a phenomenon also known as "alpha males". I don't know if the same primates will have this phenomenon, it is worth pondering.
