Video: Giant jellyfish at Portsmouth beach

LETTER OF THE DAY: Hats off to two top firms

Have your say

SEEING a jellyfish in the sea is not that uncommon - but not many people see one the size of a dustbin.

So when Kyle Chamberlain spotted the huge beast when he was fishing with his family on the beach at Eastney he grabbed his camera and filmed it.

The 27-year-old, of Romsey Avenue, Milton, said: ‘We were out fishing for the day along Eastney when my boyfriend Danny said he saw something in the water.

‘I took a look and we saw this massive jellyfish bobbing around. We thought it was a plastic bag at first.

‘Danny thinks he may have snagged it with his line when he reeled it in and pulled it into the shallows.

‘It bopped along the shore for a bit before moving back into the deep.’

It was identified as a barrel jellyfish, which are not dangerous to humans.

Lindsay Holloway, the general manager at Blue Reef aquarium in Portsmouth, said: ‘All jellyfish can sting.

‘Their stings vary widely from species to species but this one won’t harm humans.

‘They rely on their stings to catch prey.

Mr Holloway said their barrel is usually 60-70cm in diameter but in exceptional circumstances can be 90cm.

‘They are different to other jellyfish as they have a cauliflower-shaped mass underneath them which is distinctive and makes them more identifiable.’

It is unusual to see this species close to the shore as they are usually in the open waters of the Irish sea.

Dr Peter Richardson from the Marine Conservation Society said: ‘What is different this year is there are many more around the south than there usually are which we think is because they are the only species that can survive all the seasons in the UK.’

There are eight types of jellyfish in British waters but only five of them are known as ‘true jellyfish’.

The MCS recommends not touching any jellyfish but instead you can record any sightings on their website.

Jellyfish congregate where the food concentration is greatest but they aren’t dependant on each other.

This type of jellyfish live on a diet of planktonic animals.
