Oktlantis: city octopus
• Oktlantis: city octopus
The Jervis Bay off the coast of eastern Australia, researchers noticed a small "town" octopus. Scientists have named this place Oktlantis.
Cephalopods species Octopus tetricus, which translated to English called "gloomy octopus," live in "houses" of the sea sand and shells, closely communicate with each other, quarrel with their neighbors and do other things that are typical for urban residents. Population Oktlantisa - 15 individuals. This is surprising since O. tetricus were previously known for their separate way of life, reports Quartz.
The study conducted an international team of marine biologists led by Professor David Scheel from Alaska Pacific University.
"This behavior is a product of natural selection and may be remarkably similar to the social behavior of vertebrates. It says that under the right conditions, evolution can produce very similar results in different groups of organisms, "- he explains.
What exactly led to the appearance of the city is not yet clear.
In fact, this is not the first case. Oktopolis - back in 2009 in the same area, another octopus city was found. Then it is considered a complete anomaly. Community based on an overgrown coral unidentified subject is clearly man-made, there is still, at any given time there are between two and 16 octopus.
