While vaccine hesitancy remains an ongoing public health issue, claims have begun circulating on social media that the COVID-19 vaccine contains living creatures called hydras – small, tentacled, ...

Hydra, specifically Hydra vulgaris, are unassuming creatures. At their largest, the freshwater cnidarians (relatives of jellyfish) are just about a centimeter long. Their miniscule bodies are simple, ...

Although it may seem counterintuitive, researchers are turning to an animal without a brain to crack the neural code underlying behavior. Hydra vulgaris, a tiny, tentacled, freshwater organism, uses ...

Hydra is a genus of tiny freshwater animals that catch and sting prey using a ring of tentacles. But before a hydra can eat, it has to rip its own skin apart just to open its mouth. Scientists ...

Hydra is a genus of tiny freshwater animals that catch and sting prey using a ring of tentacles. But before a hydra can eat, it has to rip its own skin apart just to open its mouth. Scientists now ...

With lifespans stretching far beyond human comprehension, creatures like the hydra, Greenland shark and Aldabra tortoise don’t experience the urgency of time that fast-living species do. There are ...

The hydra, a small freshwater creature, tears itself apart every time it gets hungry. Rather than have lips, the hydra’s mouth is a sealed piece of intact skin that it tears open to gobble each meal.

From salamander tails to deer antlers, the innate ability of some animals to regenerate lost body parts has captivated scientists for centuries and driven research into the molecular mechanisms of ...

Vol. 237, No. 2, SPECIAL ISSUE: Ecology and Physiology of Dormancy in a Changing World (October 2019), pp. 111-118 (8 pages) Published By: The University of Chicago Press Despite the fact that Hydra ...

Researchers identify redundant neural networks in jellyfish-like, freshwater hydra. The work is a step toward modeling how internal states and external stimuli shape the behavior of an organism with a ...
