Eudendrium cochleatum is a hydrozoan marine animal in the Eudendriidae family.

"Hydrozoon is a name given to the great class of the sub-kingdom Cœlenterata, of which hydra is the type. They exhibit a definite histological structure, their tissues having a cellular organization. These tissues are two, an outer or ectoderm, and an inner or endoderm. In most the prey is seized by tentacles surrounding the mouth and furnished with offensive weapons called thread cells, The hydrozoa are all aquatic, and nearly all marine. Their distribution is world-wide. [Pictured] Hydra fusca, with a young bud at b, and a more advanced bud at c."—(Charles Leonard-Stuart, 1911)
