Description.
(in part after
Schuchert, 2001
)Adult medusa is5~
7 mm
in height, 5~
6 mm
in width, jelly moderately thick, much thickened at apex which gives a conical shape to the upper of the bell. Interradial exumbrellar furrows shallow. Manubrium is about two times as long as height of bell cavity, with a conical to rounded apical knob. The manubrium has no distinct short proximal part of manubrium and thin serpentine part and a swollen spindle or cylindrical shaped stomach at distal end, the thickness tapers towards distal end (about 1/3 of manubrium). The gonad encircles the manubrium from nearly its origin along the proximal 2/3 of its length, only a short basal portion and stomach is gonad-free. Four radial canals of variable breadth enter gastrodermal chambers of bulbs at their tops. Gastrodermal chambers with concave abaxial sides. Tentacles with spirally arranged nematocyst clusters along nearly their whole length, ending in slightly enlarged, globular clusters. Colors: apical knob and gastrodermal chamber of bulbs orange or scarlet, ocelli black.
Distribution
. The Bohai Sea of
China
; Near Oban, Argyll,
Scotland
.
Remarks.
The medusa of
Sarsia piriforma
has been found in plankton from the Bohai Sea, which is more similar to
Sarsia occulta
Edwards 1978
. For its distinguishing characteristics, see
