Symbiotic Relationships - Mutualism Commensal

So we're in the ocean of Southeast Asia and getting ready to search for fish that lives in a place so dangerous. The most artificial won't even come here. Ready? Let's go diving. And after a bit of searching, I finally found it, the clownfish, or anemone fish, as is also called. The beautiful tentacles of the anemone are actually deadly to most fish. The tentacles have stinging organs called nematocysts which fire tiny darts into fish to brush by. This thing ability protects an enemies from predators and help them capture prey for food, but how can clownfish hide in such a dangerous place? Well, that's because clownfish. Have a symbiotic relationship with a nominee that is so important that clownfish are almost always found among anemones. Symbiotic relationships are interactions between two species that can benefit either one or both species. Symbiotic relationships are divided up into three major categories. Parasitism benefits one species, while the other is harmed. Like ticks, for example. There are many examples here in the ocean. Take Pacific fish lights, for example, that cling to a host fish and feed on its body fluids. Amazingly fish will sometimes find a cleaner fish or clean a shrimp to help remove the parasites from their scales. Mouth and gills. When this happens, a mutualistic relationship is formed between the fish and the cleaner organism. Mutualism is a symbiotic relationship in which both species benefit from the relationship. This bird here needs to tick which benefits the cow. In our fish example, the host fish is clean off as parasites and the cleaner fish gets a free meal. Both species benefit, but not the sea lice anymore. Hey, I already brushed my teeth today. The third symbiotic relationship is commensalism. Commensalism benefits one organism, but the other one is neither harm nor helped. You might have a bug hitchhiking on you at some point without knowing it. An example here in the ocean is when remoras had to ride on sharks, big race or turtles. The remora attaches itself with the disc on its head and then hitch a ride and feed off the food scraps of the host animal leave behind. The show actually not affected by the remorse being there, but the memorials get a free ride. And free meal sounds good to me. So back to our clownfish, clownfish are protected from ProRes by living among anemones and in exchange to clownfish chase boy fish and other animals that could harm the anemone. What kind of symbiotic relationship is this? That's right, mutualistic. Okay, but we still have one important question to answer. How can the clownfish be immune to the anemone sting? Well, a clownfish must first get used to this whole cinema by developing a protective mucus coating. Kind of like when we use sunscreen. And there are two possible explanations for how this happens. The first explanation is that the clownfish secretes his own mucus which lacks a substance that makes the anemone fire is stinging the Mattis. Is as if the clownfish had a protected force field or invisible cape. And the second explanation is that the clownfish uses mucus produced by the anemone. The unprotected clownfish initially touches the nominee with its fins, even getting stung slightly at first, but over time gains the protective mucus coating. The symbiotic relationships happen everywhere, even in our own bodies. Did you know that every time you eat yogurt, you actually are filling up your digestive tract with symbiotic bacteria. That's right, you become the host of these natural bacteria, and they help you process and digest the food that you eat every day. All right, so next time you go outside, stop and look around and see how many symbiotic relationships you can spot around here. Of course what they are. And remember, never stop exploring your world.
