This is a trick question. Because hydras are only two cell layers thick, they do not have a true circulatory system. The inner cell layer absorbs materials directly from their gastrovascular cavity. So a hydra doesn't have blood!
All animals respire, but some simple animals, such as cnidarians (anemones, jellyfish, and relatives), and sponges don't have blood.
It's red - the same colour as human blood (and that of most other animals)
The blood of a lizard is typically red, just like the blood of other vertebrates. The red color comes from the presence of hemoglobin, a protein that carries oxygen in the blood.
the colour of bees blood is pale amber.
Spiders have blue blood. In human blood oxygen is bound to hemoglobin which contains iron, giving it the blood a red color. In spiders, as well as other Arthropods and Molluscs, oxygen is bound to hemocyanin which contains copper, giving its blood a blue color. The same interaction that causes oxygenated blood to color, also causes iron rust to appear reddish and the oxidized copper to appear green. However, I have noticed no color in spider blood before.
No, a hydra doesn't have blood. It is a single-cellular animal.
Pink
A hydra depending on the species can be a multitude of colors, green is just the most common.
Alphard
no it doesn't because it is extremely small and has no blood
a hydra depending on the species can be a multitude of colors, green is just the most common. Hydra is actually a genus of many species.
Yes there is because my friend showed me it then i looked in the bakugan official handbook and there it was Hydra exept when my friend showed me it the color was green but it's attribute was darkes somehow so yes there is a bakugan Hydra in this world.
Hydra appear green due to the presence of symbiotic green algae called zooxanthellae or other chlorophyll-containing organisms within their cells. These algae perform photosynthesis, producing food for the hydra while also imparting a green color. The relationship benefits both organisms, as the hydra gains nutrients and the algae receive protection and access to sunlight. This symbiotic relationship is a key factor in the hydra's vibrant coloration and ecological success.
Hydra, one of Pluto's moons, has a reddish color. This coloration is likely due to organic material on its surface, which has been created through the interaction of cosmic rays with methane and other molecules.

Hydra or Hydra
A Hydra, being a Greek word for "water serpent", does not fly. It is said to be gigantic, nine-headed: and to have blood/gall/venom that injures the Greek gods and goddesses.
