The Lancashire Wildlife Trust has issued a warning to anyone heading to the coast this summer after several jellyfish have been spotted.
A spokesperson warned people to stay away as touching them could result in a nasty sting.
Compass jellyfish and the lion’s mane jellyfish are just some that can be found in the Irish Sea.
A spokesperson for the Lancashire Wildlife Trust said: “We are noticing lots of beautiful jellyfish washed ashore on the Fylde coast.
“It is common around the Irish Sea.
“Some have a nasty sting long after being stranded on the shore so avoid touching & keep dogs away.”
North West Living Seas officer, Georgia de Jong Cleyndert, said: “At this time of year we get lots of jellyfish washing up on beaches because they are more abundant in the Irish Sea during summer months.
“Barrel jellyfish, compass jellyfish and moon jelly fish are the most commonly found along our coastline, although other species such as blue jellyfish and the lion's mane jellyfish are sometimes found too.”
Here are some of the jellyfish that have already or could be spotted on the Lancashire coast in the coming weeks:
Barrel Jellyfish
These are the largest jellyfish species.
Their favourite meal is plankton, which can be found in shallow waters. This is what often causes them to wash up.
The sting of the barrel jellyfish is not normally harmful to humans, though if you find one on the beach it's best not to handle it as they can still give a mild sting even when dead.
Compass jellyfish
These are quite distinctive with brown marking reminiscent of a compass. It feeds on small fish, crabs and even other jellyfish. They give a nasty sting, so be careful.
Moon jelly
The moon jelly is the most common jellyfish in UK seas, often washing up on our beaches.
It is recognisable by the four circles visible through the translucent white bell but this jelly fish doesn’t sting humans.
The lion’s mane
Known for its painful sting, this jellyfish has tentacles up to 3m in length which are packed with stinging cells and are used to catch their favourite prey: fish and other smaller jellyfish.
Lion's mane jellyfish give a very nasty sting, so consult a doctor if swelling persists.
In the meantime, scrape the area with a clean stick or remove the tentacle with tweezers if you have them to hand, then rinse the area with warm to hot water to reduce swelling.
