Hydra is a genus of small, simple, fresh-water animals that possess 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.Hydra has a tubular body up to 10 mm (0.39 in) long when extended, secured by a simple adhesive foot called the basal disc. Gland cells in the basal disc secrete a sticky fluid that accounts for its adhesive properties.At the free end of the body is a mouth opening surrounded by one to twelve thin, mobile tentacles. Each tentacle, or cnida (plural: cnidae), is clothed with highly specialised stinging cells called cnidocytes. Cnidocytes contain specialized structures called nematocysts, which look like miniature light bulbs with a coiled thread inside. At the narrow outer edge of the cnidocyte is a short trigger hair called a cnidocil. Upon contact with prey, the contents of the nematocyst are explosively discharged, firing a dart-like thread containing neurotoxins into whatever triggered the release which can paralyse the prey, especially if many hundreds of nematocysts are fired.Hydra has two main body layers, which makes it “diploblastic”. The layers are separated by mesoglea, a gel-like substance. The outer layer is the epidermis, and the inner layer is called the gastrodermis, because it lines the stomach. The cells making up these two body layers are relatively simple. Hydramacin is a bactericide recently discovered in Hydra; it protects the outer layer against infection.The nervous system of Hydra is a nerve net, which is structurally simple compared to mammalian nervous systems. Hydra does not have a recognizable brain or true muscles. Nerve nets connect sensory photoreceptors and touch-sensitive nerve cells located in the body wall and tentacles.

“You just might not understand it yet. But it’s cool. Family is super cool. Going home to one girl every night is super cool. Just going home and getting on the floor and playing with your child is super cool. Not wearing a red leather jacket, and just looking like a dad and shit, is like super cool. Having someone that I can call Mom again. That shit is super cool.” — Kanye West (via coffeekaling)

Fact of the Day:The giant squid, or Architeuthis dux as it’s scientifically known, has a complex yet small donut-shaped brain. The squid’s oesophagus runs through the ‘donut-hole’ of the brain making it essential for food to be ground into small pieces by it’s notorious beak.Read more about this fascinating creature herewww.ocean.si.edu/giant-squid (Graphic via funnyjunk.com)
