At first glance, the translucent creatures might seem fragile with their boneless body structure. However, did you know Moon Sea Jellies are hardy creatures that have been around even before the dinosaur age?
Newborns, also known as ephyrae are as tiny as 3mm and can grow up to 400mm in diameter. Their life span ranges from 10 months to a year.
Belonging to the most widely distributed range of sea jelly species, and commonly found on the shores of North America and Europe, the Moon Jellies are identifiable by four horseshoe-shaped reproductive organs, also known as gonads which are visible through its colourless bell-shaped figure.
Beyond the multiple small tentacles on the Moon Jelly’s body surface are four ‘arms’ located near its mouth, used to catch food like plankton such as crustaceans and young worms. When its prey swims near, the Moon Jelly shoots them with thousands of poisonous stinging cells called nematocysts, paralysing their victims.
The Moon Jelly’s tentacles might be venomous to small marine animals but are not harmful to human beings, as its sting cannot penetrate our skin.
Head to Zone 4 in S.E.A. Aquarium for your chance to admire these sea jellies.
