Male Pufferfish Make Cool Looking Underwater Circular Structures to Attract Females

Posted on August 15, 2013

A species of pufferfish make cool looking underwater circular structures 80 feet below sea level. The story was first reported last September. Earthsky.org has the story here. It recently resurfaced again on National Geographic and Japanese news sites.

These circular structures are created by male pufferfish trying to create an attractive space for a female pufferfish to lay her eggs. EarthSky says the male pufferfish will even line the grooves of the sculpture with pieces of shells. The male pufferfish guards the perimeter of the circular structure after the eggs are laid.

Here is a video of the male pufferfish in action:
