This strange sea creature is the amazing Portuguese man-of-war (Caravela Portuguesa) –.

Despite its outward appearance, the Portuguese man o’ war is not a jellyfish

A jellyfish-like marine cnidarian of the family Physaliidae. Its venomous tentacles can deliver a powerful sting.

The venomous tentacles can deliver a painful sting.

Despite its outward appearance, the Portuguese man o’ war is not a jellyfish but a siphonophore, which differs from jellyfish in that it is not actually a single multicellular organism but a colonial organism made up of many highly specialized minute individuals called zooids. These zooids are attached to one another and physiologically integrated to the extent that they are incapable of independent survival.

By all accounts, jellyfish are creatures that kill people, eat microbes, grow to tens of meters, filter phytoplankton, take over ecosystems, and live forever. Watch the video…

Because of the immense diversity of gelatinous plankton, jelly-like creatures can individually have each of these properties.However this way of looking at them both overstates and underestimates their true diversity. Taxonomically, they are far more varied than a handful of exemplars that are used to represent jellyfish or especially the so-called “true” jellyfish. Ecologically, they are even more adaptable than one would expect by looking only at the conspicuous bloom forming families and species that draw most of the attention.

In reality, the most abundant and diverse gelatinous groups in the ocean are not the ones that anyone ever sees.

With over 72% of the Earth’s surface covered by salt water, the Earth’s oceans are home to 230,000 known species. And that’s with only 5% of the Earth’s oceans considered explored! In celebration of the vast unknown of the ocean, we present our favorite amazing facts about ocean animals:
