A new paper in Genome Biology and Evolution maps out for the first time how Hydra, which are a group of small aquatic animals, can regenerate their own heads by changing the way that their genes are ...

In ancient Greek myth, the Hydra was a multi-headed monster that grew two more heads for every one that it lost. As it turns out, the real-life animal named after this mythical beast may be even more ...

In the absence of eyes, the fresh water polyp, Hydra magnipapillata, nevertheless reacts to light. They are diurnal, hunting during the day, and are known to move, looping end over end, or contract, ...

The tiny hydra, a freshwater invertebrate related to jellyfish and corals, has an amazing ability to renew its cells and regenerate damaged tissue. Cut a hydra in half, and it will regenerate its body ...

Sleep is one of biology's biggest mysteries. Every species with a nervous system has some form of resting period, and so one theory for why animals sleep is that it helps maintain the brain — allowing ...

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 ...

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 ...
