Scientific title: Glaucus atlanticus
What does it seem like? Glaucus is a really odd wanting animal. The sides of the tapering physique bear six appendages, which department out into skinny, tentacle-like projections often called cerata. These include skinny saclike outgrowths of the animal’s digestive canal. The mollusk is boldly coloured with a blue or blue-and-white again and a silvery underside, making it look as if it’s carrying sportswear. Fully grown, they’re round 5-eight cm in size.
Where does it stay? Glaucus is an animal of the open water. It is discovered all over the world in temperate and tropical seas.
We have already been launched to the Portuguese man-of-struggle and have seen the means by which this ﬂoating colony of animals catches food and protects itself. As with many defenses within the animal kingdom, they don’t supply full safety. The nemesis of the Portuguese man-of-struggle is Glaucus. Like the colonial cnidarian, this sea slug additionally ﬂ oats round, however in a really novel fashion. The animal sucks air into its abdomen, which acts like a buoyancy assist to preserve it on the floor. Also, utilizing its muscular foot, it could possibly cling to the underside of the floor muvie created when air meets water (the meniscus). Here, on the very floor of the water, it’s on the mercy of the winds and currents and is pushed and pulled across the seas. Obviously, when the ocean is calm and it’s now not buffeted by winds and tugged by currents, the ocean slug can consider looking. Using very delicate organs, the ocean slug can detect the slight taint within the water indicating the presence of a close-by Portuguese man-of-struggle or one in all it shut relations. Glaucus slowly makes for the supply of this scent, which ultimately leads to its favourite food. If the prey in query is a small specimen, a big Glaucus might merely swallow it in a single mouthful, utilizing its capacious cavern of a mouth to envelope the colonial creature. Should the prey be on the bigger facet, Glaucus will merely nibble its fishing tentacles, those that carry probably the most potent nematocysts, the stinging cells which are able to delivering very painful and even deadly stings to a lot bigger animals. The sea slug is unperturbed and eats the tentacles with gusto till they’re little greater than stubs. Eating a really venomous creature is spectacular sufficient, however Glaucus goes one step additional and turns the tables utterly on its prey. It eats the tentacles containing the stinging cells and digests every little thing however the stinging cells themselves. Exactly how its digestive system can discern between the 2 just isn’t identified, however the full, undischarged stinging cells are carried away from the abdomen and digestive sacs on conveyor belts of minute cilia. After feeding, the ocean slug will groom its appendages, distributing its new stinging cells. Eventually, these cells discover their method to the fingerlike tentacles of the ocean slug (the cerata), which every include a skinny outgrowth of the intestine. Slowly, they’re edged to the tips of the cerata, right into a saclike construction the place they are going to be nourished and primed to defend the ocean slug from its personal predators.
