Strange creatures, flexible sex, capturing males in a lifelong body!

The deep sea floor always contains unexpected stories and this worm is one of them.

Although only living at depths of more than 20m, this worm has shocked scientists to discover, when diving in the Mediterranean, it is the green spoonworm Bonellia viridis .

The reason is that this worm belongs to the Echiura class, a very difficult class to collect and difficult to distinguish, so many of them have not been thoroughly studied. Check out the video below to see their strange features!

Bonellia viridis worms will survive as larvae at a young age, yet they have no sex and no color. Only when they mature, new sex is formed based on where they live.

Deep sea ecologist Andrew Thaler wrote in Southern Fried Science: " If Bonellia viridis larvae live on the seabed, it will begin to produce toxins called bonellin and become females. The female's green color is by bonellin, which plays an important role in the existence of genes, males will be formed when another larvae come into contact with the carbonellin toxin the female secretes, at which point the male will suffer from the female. sucking on people through long taps, males will live inside females and have a duty as a sperm bank ".

At this time, the male will live the rest of his life in the genital sac of the female to fertilize according to needs and it will be nurtured by the female. With long taps that can reach 10 times the length of your body, the female will get food in the sediment layer.
