Have you ever seen a mollusk like this?

In the vast family of mollusks, there is a suborder that includes the nudibranchs, which are unique marine animals (carnivores) that can be found all over the world and at different depths.

Among them is the species called Melibe, the only one to be considered an active predator. This seemingly harmless carnivore is, in fact, equipped with a sort of expandable membrane that grabs everything that its digestive system can absorb!
