Mediterranean jellyfish venoms: A review on scyphomedusae
Being a report on the scyphomedusae
collected by the U.
A total of 27 species of jellyfish were identified: 25 hydromedusae and 2 scyphomedusae
in surface waters near the Oregon coast, May-August, 1981.

Organization of the ectodermal nervous structures in jellyfish: scyphomedusae
2001); but in the case reported here it may be explained by environmental factors such as winds and currents -like described for scyphomedusae
in Uruguay by Olague et al.
, sensory information has to be conducted in a similar non-polarized manner since receptors are distributed around the margin of the bell, either via marginal tentacles or other marginal structures.
Diet and prey selectivity of scyphomedusae

In comparison, scyphomedusae
possess rhopalia but without the connecting tracts of a nerve ring, while hydromedusae have a pair of complex nerve rings representing their centralized nervous systems (see Satterlie, 2011).
