Dromalia is a monotypic genus of rhodaliid siphonophore, containing the single species Dromalia alexandri.[2] It is one of several siphonophores commonly referred to as deep-sea dandelions.
Description
D. alexandri is characterized by a distinctive pneumatophore compared to other rhodaliids. The pneumatophore has a flattened shape with several processes extending from its rim. Its walls are also notably thick and rigid compared to other genera.[3]
Its zooids have a salmon pink or orange colour.
Distribution
Specimens of D. alexandri have been collected in the Pacific ocean at depths ranging from 100 to 800 meters (330 to 2,620 ft).[3]
