Jeanbouillonia maserati is a species of the Hydrozoa (Hydrozoa)living in the North Atlantic. The species is the only species in the genus Jeanbouillonia , which in turn is the only genus in the family Jeanbouillonidae . The genus is named after Prof. Jean Bouillon , an outstanding researcher of the hydrozoans. The specific epithet alludes to the company emblem of the car manufacturer Maserati , as the shape of the medusa tentacle is reminiscent of a trident.
features
No hydroid polyps are known to date. The medusa , about 3 mm in diameter, has a strongly curved, spherical umbrella without an apical projection. The manubrium is cross-shaped, colored orange and about 1 mm high. The ridges are perradial, the deep pits interradial. The mouth has four simple lips that reach the opening of the screen. There are four straight radial channels. The flat, yellowish colored gonads are attached to the manubrium interradially, the perradial backs are spared. There are four marginal pistons, only one piston has a trident-like, approximately 1.5 mm long tentacle. The piston opposite the tentacle-bearing piston has only a small bulge instead of the tentacle. The remaining two marginal pistons are rudimentary without tentacles or bumps. Seven to eight nettle cells sit on each of the marginal bulbs.
Geographical occurrence
The species has so far only been caught from the Georges Basin in the North Atlantic (42 ° 25.3 'N and 67 ° 31.3' W) between 290 m and the sediment surface there at a depth of 297 m.
