Nemo have symbiotic mutualisms with sea anemones. Who is sea anemone? Sea anemone is a frilly pipe-shaped sea creature, much like swaying hair/tentacles. It looks like colorful flowers under the sea, but anemones are actually animals, not plants. Where there are anemones, there usually lives a nemo. Where there is nemo fish, there is high probability anemone lives nearby. Anemones is poisonous sea creatures. Nobody dared to touch, except nemo.
A theory states why Nemo can live in anemone, while others can’t. The first theory states that nemo skin mucus containing sugar, while anemones recognize their prey by stimulation of protein. Thus, Nemo is safe to stay around anemones because anemone do not recognize Nemo as prey. The second theory states Nemo has evolved to become resistant to the poisonous tentacles of the anemone.
They have a mutually beneficial relationship known as symbiotic mutualism. Anemone food scraps will become food for Nemo. Instead, Nemo fish waste into a source of nutrition for anemone. Anemones also become a nest for Nemo, the juvenile, and eggs. Meanwhile, Nemo is also protecting anemone from predators. No wonder if we approached nemo, he would hide behind the anemone to cover or the other way around will be going to attack us. Nemo movement also helps the circulation of water and air around anemone, thus helping anemone to grow.
2. No Nemo in the Atlantic Ocean

While growing up, those who have a dominant position in the group will turn into a female. If the female dies, the male will eat other Nemo. Those who have a dominant role will turn into a female.
4. Nemo fertilize outside the body
Male spread sperm and females release an egg outside the body. If the sperm and the egg is met, there will be a fertilization. This is in contrast with the conception of animals in general that fertilization occurs in the female’s uterus. The male will guard the eggs that have been fertilized until hatching.
5. Nemo’s black and white stripes size on the body is affected by the type of anemone
There are various types of anemones. Reportedly, different types of anemones also affect the body color nemo. Nemo who lives in Stichodactyla gigantea anemones has a darker black color than those who live in other types of anemones.
