Welcome to brain stuff from how stuff works. Hey, brain stuff learned vocal bomb. Here you probably have a favorite seek cucumber. And don't even know it. There are over one thousand two hundred species in the world's oceans, so many that scientists are even confused about exactly how many there are. So there's probably one you'd like a lot. Some of them are decked out with the colors of your favorite sports team. Others look like somebody crocheted an oversized zucchini out of Brown acrylic yarn. Even if you weren't particularly interested in a living sea cucumber, you might want to eat a dead one or even take one as medicine, but if you don't know already had to guess, would you bet a sea cucumber is an animal or vegetable they tend to come in to form like a sweet potato of the C. They look vegetable ish, but they are in fact animals the thing where we refer to them as cucumbers doesn't help. But they're Aquino terms, a file of marine animals that also includes starfish and sea urchins everybody in this violence has what's called Penn. Tomorrow symmetry? They have five arms arranged around a center point. Of course, the kindest thing you can say about a CQ Cumbria's physique is that it looks like a large hoagie bun that you wouldn't want to eat. But though it more closely resembles a slug than a star the five rows of tube feet that extend from its mouth to its anus give it the same basically out as say a very elongated sea urchin that fell over on its side seat. You have a different approach to reproduction than we do. They are usually born either male or female, but can change from one to the other during their lives. They communicate with each other by releasing hormones into the water, which is very similar to their style of reproduction. They expelled their gimmes. Those are the egg and sperm cells out into the water column. And just assume that they'll find each other just as they assume that their friend got the hormone message that they left sea cucumbers, eat tiny animals particles of algae and general see junk out of the water using frilly tentacles that between meals they keep hidden in their mouths what they have in the way of a brain is a ring. Of nerve cells around their mouth that tells them when it's time to eat burrow into the sand walk somewhere or attack and even though they look like tube, socks filled with modeling clay, a sea, cucumbers defense mechanism is pretty terrifying. Imagine you're roughhousing with a friend or sibling or maybe taking a martial arts class. I'm willing to bet that your opponents defense mechanism would not be to shoot out some of his respiratory organs at you out of his rear, but that's what seek you cover combat looks. Like, they have the amazing ability to regenerate the organs that they lose this way. Some species spit out sticky string like spider webs to trip up or in snare their enemies, while others heavy special toxin that kills or stunned small animals don't mess with sea cucumbers, but we do mess with sea cucumbers all the time some species are at risk of extinction because in some Asian countries sea cucumbers are the ultimate luxury snack. Some tropical species can go for between ten dollars and six hundred dollars per kilogram. Dried in mainland, China and one type. Tails for three thousand dollars per kilo sea cucumbers are also used in Chinese medicine to treat a variety of elements like muscle, aging compromised immune system, fatigue and arthritis. Some even suggested they could be used in cancer treatments. The variety is that are used in food or medicine are becoming increasingly rare due to overfishing or over cucumber ring as a result there around three hundred and seventy seven species of sea cucumbers on the red list of threatened species put out by the international union for conservation of nature seven of these are classified as endangered and nine as vulnerable, but we need sea cucumbers, not only are they economically important as a seafood they are essential to ocean ecosystems, they're important filtration systems for watery habitats. All over the world in some places in the deep ocean vast herds of sea, cucumbers, roam the ocean floor gobbling up detritus that drifted down from above. Plus, some species provide vital services for other marine life, the Pearl. Fish, for instance, takes refuge. Wjr innoc-, cucumbers anus sometimes entire schools of Pearl. Fish can find shelter in the rear end of a single seat. Cucumber? They usually don't mind much in less. They're trying to use their anus to breathe at the moment. Oh, yeah. Seat you numbers breathe through their Amos's. I forgot to mention that part.
