The Ocean Wanderer That Is Not A Jellyfish

The Portuguese man o' war is not a single animal, but a floating colony of four distinct organisms working together. These tiny individuals are so specialized they cannot survive on their own.

What looks like one creature is actually a complex team of polyps living in a symbiotic union. Some handle digestion, others focus on reproduction, and some act as long, stinging tentacles for defense. Because they are physically fused, they rely on each other to eat, move, and reproduce. If you separated them, the entire colony would fail to function.
