Phages can kill bacteria on or in a multicellular host organism, such as the polyp of the moon jellyfish. Phages specialize ...

Jellyfish start out in a stationary polyp stage and later develop into jellyfish, when environmental conditions are right. The Morbakka virulenta, pictured here, is beginning to develop into a ...

There are some 3,600 species of hydrozoans. These are typically smaller than scyphozoan jellyfish. The polyp stage of their lives is usually more conspicuous than the small adult jellies. However, not ...

This fingernail-sized, unassuming creature possesses the rare ability to revert back to its juvenile polyp stage after reaching maturity, which is an early stage in the life cycle of a jellyfish ...

For the project, scientists studied the polyp stage of the upside-down jellyfish, a juvenile life stage. During the polyp stage, jellyfish can live with or without symbiotic algae, setting up a ...

There are a couple of main reasons. The Peach Blossom Jellyfish spends most of its life cycle as a tiny polyp about one to two millimetres in length. A population of polyps can survive for years ...

So why are we only hearing more about them now? There are a couple of main reasons. The Peach Blossom Jellyfish spends most of its life cycle as a tiny polyp about one to two millimetres in length. A ...

Some species never grow up; they remain branching colonies of polyps. And one hydrozoan, the immortal jellyfish (Turritopsis dohrnii), seen here in a water drop, has a life cycle that skips death ...
