The world we know of is a peaceful under water world. But it's not. Just as there are enemies on Earth there are little blood-sucking mosquitoes down there. These mosquitoes are called isopods.Scientist also found out that to protect them selves, the coral reef fish wrap into mucus before going to sleep. Some reasons that they cover in mucus are that they want to be safe, not attract the moray eels and the isopods. To have more clues of what is happening, scientist from the University of Queensland in Austria have done some work and experiments. First of all, they gathered some of the coral reef fish and put them in a tube. They waited until midnight so the fish could make their cocoons. After all the fish were sleeping the scientists removed the cocoon from some of the fish and left the other ones alone. Finally they placed some isopods into the tubes and 94 percent of the fish without the cocoon got bitten. 10 percent of the fish weren't bitten because they were covered in cocoon and that was the challenge for the enemies.The fish produce the cocoon from their mouth and it takes one hour to make it go on their whole body. This process take up 2.5 of their body energy. Once the fish have started this cycle they will be more safe and will have a better underwater life.
I choose to write about this article because I like to know about what is new about animals. I also thought it was interesting reading this article because I never knew that there existed underwater mosquitoes and that fish have to protect their selves.
Some interesting words that I found were:
Snot: mucus from the nose
Isopods: marine mosquitoes
