Jenni's Beach Adventure Journal

Tuesday the 1st of February, 2022 . . . Main Beach, Iluka, Northern NSW
I was stunned to stumble across one of the worlds largest jellyfish on a beach near me! I honestly did not know what it was, so I did some research and found out it is a Lion's Mane Jellyfish - meaning that it "has all the beauty and bite of a lion"!
They can grow up to a massive 1m across with its trailing tentacles reaching more than 10m in length. Wow!! I found out that their tentacles are very fine (sort of like feathers) and are very difficult to see and will definitely pack a punch if you touch them...so don't!!
Their tentacles can extend outwards in a fan-like trap through which only the smallest of animals can pass without being caught. Some of the larger jellyfish have small fish that live near their bell so they can avoid the stinging tentacles and gives them protection from predators. Smart fish!
Apparently there very few creatures that would approach a Lion's Mane Jellyfish underwater...I know I wouldn't!
They are colourful but can deliver a painful sting, so it's best to stay clear of them both in the water and on the beach.

Here is my photo of the Lion's Mane Jellyfish. It looks soft and blubbery, but they can deliver a painful sting, so no way was I going to touch it!

They live in the marine waters around Australia and northern areas of the world.

Jenni’s Adventures

I love being outdoors in nature and I love exploring our beautiful beaches and coastlines. I find lot's of amazing things on my daily walks along the beach. Come and join me as we explore the beach together!

Numb-Ray

I came across this odd looking sea creature washed up on the beach today. It was stuck in the sand and a long way from the water…so what to do?

Green Sea Turtle

On my morning walk today I found this gorgeous sea turtle on the beach. It looked unwell…so what should I do?

Is there anything cuter than a lamb yawning?.. nope I didn’t think so either until I met this baby Joey and its mum.
