Hydroidolina

Also known as Hydroid subclass

Hydroidolina is a subclass of Hydrozoa and makes up 90% of the class. Controversy surrounds who the sister groups of Hydroidolina are, but research has shown that three orders remain consistent as direct relatives: Siphonophorae, Anthoathecata, and Leptothecata.

Los hidroidolinos (Hydroidolina) son una subclase de cnidarios hidrozoos que incluye las hidras, hidromedusas, y varios organismos marinos afines, muchos de los cuales crecen en grandes y elegantes colonias de pólipos. En los hidroidolinos suele predominar la fase de pólipo, y las colonias acostumbran a ser polimórficas y dioicas; todos los zooides de una colonia provienen, por reproducción asexual, de un solo progenitor zooide. En muchos casos, las medusas no llegan a separarse de la colonia, quedando reducidas a esporosacos o gonóforos.
