Moreover, what do Hydroids do?

A hydroid is a type of vascular cell that occurs in certain bryophytes. In some mosses such as members of the Polytrichaceae family, hydroids form the innermost layer of cells in the stem. Collectively, hydroids function as a conducting tissue, known as the hydrome, transporting water and minerals drawn from the soil.

One may also ask, what is a Marine Hydroid? Hydroids are a life stage for most animals of the class Hydrozoa, small predators related to jellyfish. Some hydroids such as the freshwater Hydra are solitary, with the polyp attached directly to the substrate. When these produce buds, they become detached and grow on as new individuals.

Hereof, where do Hydroids live?

They are commonly found in the Atlantic, Pacific, and Indian oceans and they are located both inshore and offshore. Hydroids and jellyfish live mostly in warm and tropical waters but, in reality, can withstand temperatures as low as –6 degrees Celsius (Rodriguez, 1996).

How do you treat hydroid stings?

First aid treatment for most fire coral, hydroid and jellyfish stings is the same. Rinse the affected area with seawater (do not use fresh water as this will cause the nematocyst to 'fire' again). Soak the area in 5 per cent acetic acid (vinegar) for 15-30 minutes to further de-activate the nematocysts.
