LISBON, Portugal, June 14 (UPI) -- A diver off the coast of Portugal captured footage of two octopuses giving each other an underwater high five -- or high tentacle.

The video, recorded June 1, shows the pair of octo-bros engaging in the cephalopod version of the typically human greeting by touching the tips of their tentacles.


The octopuses then pull away from each other and return to their preferred spots on an underwater rock formation.

The diver filming the spectacle can be heard giggling at the display.
