      When did hydrozoans first appear?
      The earliest hydrozoans may be from the Vendian (late Precambrian), more than 540 million years ago. Hydrozoan systematics are highly complex. Several approaches for expressing their interrelationships were proposed and heavily contested since the late 19th century, but in more recent times a consensus seems to be emerging.

      How do Hydrozoa reproduce?
      Many members of the Hydrozoa go through a body change from a polyp to an adult form called a medusa, which is usually the life stage where sexual reproduction occurs, but Hydra do not progress beyond the polyp phase. Hydra mainly feed on aquatic invertebrates such as Daphnia and Cyclops .

      How many tentacles does a hydrozoan medusae have?
      Most hydrozoan medusae have just four tentacles, although a number of exceptions exist. Stinging cells are found on the tentacles and around the mouth. The mouth leads into a central stomach cavity. Four radial canals connect the stomach to an additional, circular canal running around the base of the bell, just above the tentacles.

      Los hidrozoos (Hydrozoa, del griego hydra, serpiente acuática, y zoon, animal) son una clase del filo Cnidarios que presentan especies marinas y dulceacuícolas.

En la mayor parte de casos…
