Top 5 Facts about Jellyfish.

They’re a pretty familiar sight to our Cornish beaches over the summer, and always provide interesting photos, debates and conversations but truthfully how much do you know about jellyfish? Here is myCornwall’s Top facts list about these gelatinous guests, as adapted from our article in the latest myCornwall magazine:

1: Jellyfish are closely related to sea anemones and corals, but instead of living attached to the seabed, they’re at the mercy of the ocean currents.

2: They’re so delicate that even one tiny air bubble caught inside their body will tear it apart.

3: Jellyfish have a two stage lifecycle. The ‘parents’ of the jellies we find in our seas are actually tiny anemone-like creatures called jellyfish polyps.

4: Within a few hours’ millions of baby jellyfish are produced at once, and these hungry little stingers then drift with the currents, and if the conditions are right, a swarm of jellyfish will be created.

5: The most common jellyfish found in Cornish waters only give a mild sting, like a nettle. However, some very rare visitors to our waters (reddish coloured Lion Mane’s jellyfish and the Portugese Man of Water) can give stings that can be very painful and very serious.

A huge thank you to Matt Slater of the Cornwall Wildlife Fund who gave us all this interesting information along with these great photos.
