|
Maximum diametre: approx. 20 cm.
Appearance: The compass jellyfish has a yellow-whitish colour
with characteristic brown V-shaped lines on top of the "umbrella". The
relatively large tentacles are few (24), and the four mouth
arms are wrinkled and noticiably long.
Compare the compass jellyfish with the
lion´s
mane jellyfish.
Depth: From sea-level to unkown depth.
Environment: Pelagic.
Misc: Compass jellyfish change sex: first they are male, followed
after by female. The medusae
live mainly off other medusae, comb jellyfish and arrow worms. This
species is a rarity in scandinavian waters, but medusae occasionally
drift into nordic
waters from the south during the summer and autumn.
