Today, on October 8, animal rights activists and all fans of the fauna of the sea and ocean depths can join the events on the occasion of World Octopus Day, UNN writes.
According to zoologists, the ancestors of octopuses appeared on our planet more than 300 million years ago. At the moment, scientists have described and classified about 100 species of octopuses.
A characteristic feature of these cephalopods is their three hearts. The main heart, which consists of two atria and a ventricle, drives the blue blood through the body. The other two push blood through the gills.
Octopuses are considered to be among the most intelligent invertebrates - their brains have some gray matter. Each octopus tentacle has up to 10 thousand taste buds.
The maximum length of octopuses known to science is 1.3 meters, and the maximum weight is 10 kilograms.
