Lifeguards have issued a warning following "several reports" of Portuguese man o' war being washed up along Gower beaches.
It comes after an "unusual amount" of smaller and "baby" marine creatures have been reported to volunteer group - Langland Bay Lifeguards - with sightings also made in Oxwich, Llangennith and Crofty.
Often mistaken for jellyfish, but actually a colony of organisms all working together, known as a siphonophore, the beings have also washed up along North Wales beaches where they have been labelled as a 'floating terror' often being mistaken for plastic.
