Eudendrium racemosum

Eudendrium racemosum is a marine species of cnidaria, a hydroid in the family Eudendriidae. It was described by Cavolini in 1785. Hydroids are one of the most abundant organisms in hard-substratum benthic communities, more specifically in temperate seas, such as the Mediterranean. Similar to most modular organisms, they have high growth rates. In fact, E racemosum has been frequently found in northeastern Spain, specifically in Medes Islands, showing a maximum population density in summer with a minimal density during the winter. Their rapid growth coupled with their ability to store the necessary material to survive the winter is due to their efficient feeding and digestive methods.
