"Stings from Portuguese Man o' War can be very painful and potentially harmful to humans and dogs alike."

Offshore reefs at the Écréhous and Minquiers are now protected by Jersey law, after five years of negotiations with French authorities.
The States has passed the ban on disturbing the reefs by dredging and trawling unanimously today.
The ban protects two large marine areas, totalling 62 sq km (23.9 square miles), of important and sensitive habitats in the shallow seabeds around Les Minquiers and Les Écréhous.
Environment Minister Steve Luce said the "complex" agreement with French authorities was under the Granville Bay agreement on shared fishing rights.
He said the reefs were home to "extensive areas of seagrass, maerl and kelp", which were important "nursery grounds" for fish and shellfish.
He added that the new law was a "crucial step" to protecting the island's marine environment.
