From little things ..big things grow….On a recent discovery walk at Spencer Park we saw a Lion’s mane jellyfish floating in very shallow water .
They are reputedly the largest jellyfish in our oceans& can grow to 2-3m across with tentacles that may stretch for 30m in length [our specimen was only about 12cms in diameter !!] They start life as a small larva feeding on plankton in cold ocean waters.The jellyfish uses its tentacles spread out as a net to capture food in its poisonous stingers.
The venom stuns its victims and smaller tentacles guide food into the jellyfish’s mouth .
The stingers stay venomous for a few days after being detached from the body .
