Reef Mantas in the Red Sea - Paper!

Reef Mantas or Giant Mantas? Source.

Very Cool.

Reef Mantas are shown to engage in deep dives during the night.

Apparently, they are mostly targeting Plankton that ascends from the deep at night - but the authors speculate that occasional very deep dives to up to 400m are not for foraging but instead, a more efficient way of traveling.

Synopsis here, open access paper here.

Enjoy!
