Nature, 1959
IN June of this year a small medusa appeared in a salt-water aquarium tank at Aberdour, Fife. Stones placed in this tank had been gathered on the shore and dredged from below low-water mark at Aberdour. These stones had unidentified hydroids attached. Other medusae appeared during June and July.

Notes on hydromedusae (Cnidaria) from the Adriatic Sea
Journal of the Marine Biological Association of the United Kingdom, 1977Earlier studies on the problems of the Adriatic Sea and the knowledge of its hydromedusae are restricted to the northern part. Will (1844) mentioned six species of hydromedusae found in the Bay of Trieste. Several studies ensued from the northern part of this sea, until Neppi (1912, 1915, 1922), Pell (1911, 1938), Kramp (1924), Babnik (1948) and ...

Hydrobiologia, 1991Mediterranean hydromedusae can be classified in several categories: common species, widely distributed throughout the Mediterranean and rare species reported from the Pacific, Indian or Atlantic Oceans; seasonal species comprising cold-season species with a boreal affinity and warm-season species with a hot to temperate affinity; neritic and mid-ocean ...

Gastrovascular System of Small Hydromedusae: Mechanisms of Circulation
Science, 1967Small medusae possess a circulatory system of narrow tubes subdivided into several compartments by functional "sphincters." Flow is activated by gastrodermal flagella twice as long as the diameter of the tubes. The flow may be reversed in any part of the system through pressure waves generated by muscular action of the gastric pouches.

Development and Medusa-Bud Formation in the Hydromedusae
The Quarterly Review of Biology, 1950T H HE Hydromedusae or Hydrozoa are usually conceived as coelenterate organisms alternating between a sessile hydroid phase which reproduces asexually to form medusae, and free-swimming medusae which reproduce by means of fertilized eggs, the eggs developing into planula larvae which settle and grow into hydroids. This is true enough of the majority of
