Nature Foundation posted this warning.
"Late yesterday afternoon and today the Nature Foundation has received calls from beachgoers experiencing stinging sensations in the water. Yesterday the area of Mullet Bay was affected and today Great Bay has experienced the same.
Beachgoers were complaining about a fiberglass-like irritants in the water. Upon investigation, they were found to be a Pteropod called 𝑪𝒓𝒆𝒔𝒆𝒊𝒔 𝒂𝒄𝒊𝒄𝒖𝒍𝒂, more widely known as Sea Butterflies.
These marine animals are a type of snail can usually be found in warm tropical waters drifting with the current. Though not dangerous to humans, being in contact with these tiny creatures may feel like small shards of glass puncturing the skin (which may cause small reddish bumps). Not to worry though, as these unique creatures tend to hunt at the surface during the night and migrate in the morning. Seawater temperature has been suggested as an important factor influencing such occurrences in other parts of the world.
Those with more sensitive skin should avoid swimming in the mentioned area for the time being. If you are in the water with Sea Butterflies be sure to thoroughly wash any swimming gear after exiting the water. When dry these shells become sharp and cling to clothes making them harder to remove."
