hydroid

It was first isolated and reproduced in 2008 from cells of the freshwater hydroid Hydra.

This is a red or pink hydroid growing to 15 cm tall but usually only half this size.

A hydroid is a type of vascular cell that occurs in certain bryophytes.

The form of the hydroid is very variable and this was one of the reasons for the taxonomical confusion.

The hydroid looks superficially like fronds of seaweed.

The small freshwater hydroid, hydra, has a glove-like form, its tentacles being used to capture prey.

The hydroid grows rapidly and may starts to produce medusae when as little as seven weeks old.

B. muscus is a colonial hydroid forming irregular, straggling branched bushes.

This is a many-branched rose-coloured hydroid, up to 15 cm tall with distinctive ringed stems and branches.

Hydroid may refer to:

Hydroid (zoology)

Hydroid (botany)

The B. muscus hydroid buds and forms medusae by asexual reproduction.

Clava multicornis, a species of marine hydroid.

These polyps develop over a few days into tiny 1 mm medusae, which are liberated and swim free from the parent hydroid colony.

Hydra vulgaris the fresh-water polyp is a small animal (12mm) freshwater hydroid.

Bougainvillia frondosa is a marine invertebrate, a species of hydroid in the suborder Anthomedusae.

William James Rees (1913 - 1967) was a British hydroid and cephalopod researcher at the Natural History Museum in London.

Huxley united the Hydroid and Sertularian polyps with the Medusae to form a class to which he subsequently gave the name of 'Hydrozoa'.
