Yesterday, I posted a photo of Glaucus atlanticus — a strange little creature, related to mollusks, which floats through the ocean and eats (among other things) the jellyfish-like Portuguese Man-Of-War.
In response, marine biologist Christopher Mah sent over this video, in which two specimens of Glaucilla marginata — a smaller relative of Glaucus atlanticus — nibble on the still-living flesh of a colonial organism called a blue button. This proves to be cuter than it sounds.
Part of what makes the video so mesmerizing is watching the Glaucilla marginata move around. These creatures travel in a very laid-back way. Inflating a gas bubble in their stomachs, they float around on their backs, wherever the waves will take them. That bubble seems to lead to some endearing, baby-sloth-like flips and turns as they try to position themselves to take bites out of the blue button. OM NOM NOM.
