Discovering strange creatures without brains, one eye can eat meat

Experts hope, this creature opens new hope in the study of eye evolution in organisms.

Strange creatures have no brain, one eye can eat meat

Scientists at the University of São Paulo in Brazil have recently discovered the world's most exotic predator - a tiny single-celled creature with no brain and only one eye at a depth of 90 meters in one positive in South America.

Researchers have named this tiny creature Erythropsidinium . Along with that, they also discovered that Erythropsidinium's eye has a structure like an eyeball, sensitive to light, like the eyes of vertebrates or humans.

Further research, Dr. Fernando Gómez of São Paulo University discovered, although only one eye but Erythropsidinium has the ability to aim directly at the prey and shoot a very small extremely precise dart .

Sharing with New Scientist, Gómez said: "Erythropsidinium belongs to a group of marine plankton, known as algae. They use a small tail to move around. When they detect prey, they "It will not always be Erythropsidinium, but it is not always possible to aim at the target."

According to experts, it seems that Erythropsidinium is much more subtle. Dr. Gómez believes that this creature can detect prey by a special eye but many other experts believe that Erythropsidinium can hardly see its prey with its " absence". Brain processing information.

However, Gómez argues that the eye part of Erythropsidinium (called ocelloid) can align the size, position, and path of the prey accurately.

Research on ocelloid in this organism, experts believe, they can better understand the evolution of the eye. This made the experts remember Charles Darwin 's theory.

Accordingly, a "perfect and extremely complicated organ " like the eye can be formed by natural selection. Now scientists continue to study the transition of the eye to check the accuracy of this theory.

The study is published in the journal Public Library of Science One.
