From editor or global species database
Remark Hydroids are quite easy to obtain from medusa but they are very small, maximum 0.6 mm high. It makes it almost impossible to find them in nature. On September 13th 2002 I found five reduced hydroids on translucent plastic floating in the marina in Zeebruge. Medusa are present in Zeebrugge from half May until the end of October, sometimes in large quantities. The medusa typically have a pair of club-shaped tentacles in the middle of each tentacle bulbus. It was observed how the club-shaped tentacles developed from normal tentacles. A medusa of 2.5 mm was sampled, it had 4 long tentacles on each bulbus. The next day, the 2 middlemost tentacles contracted to form the club-shaped tentacles. A medusa of 3-4 mm has 6 tentacles, the middlemost already club-shaped, but still able to extend them for a reasonable length. Statistics of measurements in relation to the number of tentacles and branching of the stomach tentacles are made on 120 individuals. [details]

From other sources
Alien species The hydroid Nemopsis bachei occurred naturally only along the Atlantic coast of North America. By attaching their polyps to hulls of ships; the species might have reached Europe in the 19th century. The jellyfish stage in the hydroids reproductive cycle allows it to spread rapidly. The species was first reported along the Belgian coast in 1996 in the port of Zeebrugge. [details]
