The Undying Hydra: A Freshwater Mini-Monster That Defies Aging | Deep Look
Could this tiny creature, named after a mythical multiheaded monster, hold the secret to eternal youth? Related to jellyfish and anemones, the hydra has an almost otherworldly ability to heal itself and stave off aging.

What is a Hydra? Amazing creature with remarkable regenerative capability!
Hydra is a genus of tiny fresh-water organisms that are classified under the phylum of Cnidaria. Hydra has a cylindrical, radially symmetric body from 2 to 20 mm in length. It is visible to the naked eyes when fully extended.
Typically, Hydras remain attached to some underwater objects, waving their tentacles slowly with the current. This is why the hydra is often mistaken for a plant or alga. However, it is a bona fide animal!
Hydra is characterized by its tentacles around the mouth opening. These tentacles can greatly extend to catch the prey or use for locomotion. Each tentacle is clothed with many stinging cells. Upon contact with prey, the contents of the stinging cells are explosively discharged, firing stings that can paralyze small animals.
Biologists are especially interested...

Phylum Cnidaria Part 2: Class Hydrozoa
As we now know, there are five major classes within phylum Cnidaria, and we will go through them one at a time. First up is class Hydrozoa. This contains a variety of small predatory polyps, such as hydras. These are fascinating creatures which can undergo morphallaxis, or tissue regeneration. They also do not senesce, making them biologically immortal. We will also cover other fascinating organisms like siphonophores. There's much to learn, let's get started!

Biology Research Project: Stinging Cells in Hydra
This video was made as a final project for a biology course. I plan to make another version that is a bit more produced, with more footage, but in case that never happens, this is my Hydra video for now. These creatures are fun to watch and you only need your eyes and maybe a magnifying glass to enjoy them. Most of the footage comes from my smartphone attached to the eyepiece of my microscope.

Watch: Tiny Hydra Rips Its Mouth Open to Eat | National Geographic
Before a hydra can eat its prey, it has to rip itself apart to form a mouth. Scientists had noticed that its mouth disappears after it eats, but until now they had not seen exactly how the mouth actually forms. See it happen in this eye-opening footage.

Living Hydra (genus) Super Cool!
Hydra (pron.: /ˈhaɪdrə/) is a genus of small simple fresh-water animals possessing radial symmetry. Hydra are predatory animals belonging to the phylum Cnidaria and the class Hydrozoa. They can be found in most unpolluted fresh-water ponds, lakes, and streams in the temperate and tropical regions and can be found by gently sweeping a collecting net through weedy areas. They are multicellular organisms which are usually a few millimetres long and are best studied with a microscope. Biologists are especially interested in Hydra due to their regenerative ability; and that they appear not to age or to die of old age.

The hydra gets its name from the Lernaean Hydra, a monster from Greek mythology that guarded an entrance to the underworld. Chop off one of the beast’s many snake-like heads and two would grow in its place.
While much less formidable in size, the real hydra does have a remarkable ability to heal from injuries. Cut a hydra in half and within a few days the bottom half will grow a new head. The severed head grows a new body.
The secret to the hydra's ability to heal and its seeming ability to not age is the abundance of stem cells that make up the hydra’s tube-shaped body column.
“The reason why hydra lives so long is because it has these continually active stem cells populations which don’t seem to slow down at all,” said Celina Juliano, a molecular and cellular biologist at UC Davis.
“They’re just constantly remaking all of the cells in the animal so every 20 days all of the cells are replaced with new cells.”
--- What does a hydra eat?
Hydra use their tentacles to ensnare swimming prey. Stinging cells in the tentacle paralyze the prey, which the tentacles then move toward the hydra’s mouth. Hydra often eat like Daphnia and other aquatic invertebrates referred to informally as water fleas.
--- How do hydra reproduce?
Hydra can reproduce asexually by cloning themselves. The new clone, called a bud, grows directly from the hydra’s side and eventually detaches. In addition to cloning, different species of hydra have different sexual reproduction strategies.
--- How do hydra recover from injury?
A large amount of the cells in a hydra’s central column are stem cells. These cells can reproduce themselves and can also differentiate into all of the different specialized cells that make up the hydra's body.

Hydra is a genus of tiny fresh-water organisms that are classified under the phylum of Cnidaria. Hydra has a cylindrical, radially symmetric body from 2 to 20 mm in length. It is visible to the naked eyes when fully extended.
Typically, Hydras remain attached to some underwater objects, waving their tentacles slowly with the current. This is why the hydra is often mistaken for a plant or alga. However, it is a bona fide animal!
Hydra is characterized by its tentacles around the mouth opening. These tentacles can greatly extend to catch the prey or use for locomotion. Each tentacle is clothed with many stinging cells. Upon contact with prey, the contents of the stinging cells are explosively discharged, firing stings that can paralyze small animals.
Biologists are especially interested in Hydra because of their remarkable regenerative ability – they do not appear to die of old age, or to age at all.
In this video, you will learn about this fantastic creature in detail. I will show you several interesting behaviors when a hydra feeds or move. Finally, you will also learn where and how to collect a hydra for your microscopic project. Let’s go.

If we were to write a fable to get this moral across, it would have to star the freshwater cnidarian called the hydra. Because in the hydra, the question of butts connects to the ambiguities of immortality, which in turn relates to the befuddling matter of sexual reproduction.

Hydra (pron.: /ˈhaɪdrə/) is a genus of small simple fresh-water animals possessing radial symmetry. Hydra are predatory animals belonging to the phylum Cnidaria and the class Hydrozoa. They can be found in most unpolluted fresh-water ponds, lakes, and streams in the temperate and tropical regions and can be found by gently sweeping a collecting net through weedy areas. They are multicellular organisms which are usually a few millimetres long and are best studied with a microscope. Biologists are especially interested in Hydra due to their regenerative ability; and that they appear not to age or to die of old age.
