Once the little puffer has attracted a mate, the sand ridges serve as protection from ocean currents that can dislocate newly laid eggs and future young. via colossal.

The fact that they found this out that the puffer was the culprit of making these designs! It just blows me away.. how can they be so straight and perfect like that. People are talking of these being related to aliens and crap but that’s bogus talk HAHA this is just a fish doing what it likes to do. Cool video.
