The Candelabridae are a family of hydrozoa (Hydrozoa) from the tribe of the cnidarians (Cnidaria) that live exclusively in the sea . It is a small family of currently 18 species in three genera .
features
The representatives of this family do not develop a free medusa stage , only polyps . The hydroid polyps are solitary or form pseudocolonies. The hydrocaulus (stem) is relatively short with tubular or root-shaped appendages. A perisarc can be present or absent. The hydrants are large and elongated. They are covered in the upper part of the body with irregularly distributed capitate tentacles. The fixed gonophores develop below the region of the body, which are covered with tentacles. They develop directly on the hydrant or on spindle-shaped blastostyles . The gonophores are tight sacs of spores.
Geographical occurrence
The representatives of the family occur in the North Atlantic, North Pacific, in the waters around Antarctica and off South Africa.
Systematics
Currently 19 species in three genera are assigned to the family
