Sea jelly
Cnidaria – Scyphozoa
Sometimes referred to
as jellyfi sh, the sea jelly is not a
fi sh at all as it lacks vertebrae. Sea jellies
have a bowl or bell-shaped body, fringed
with tentacles and oral arms. Largely at the
mercy of the oceans currents, sea jellies
drift in the oceans, feeding on plankton and
small fi sh. There are many different kinds
of sea jellies; some more common ones
include the moon jelly and
spotted jelly.
Did you know?
Sea jellies have specialised
stinging cells called nematocysts
that aid in defence and the
capture of prey.
