They’re Here… Portuguese Man-o-War

Last weekend, the first Portuguese Man-o-War of the season were spotted off of Cisco and Ladies Beaches. By the time this article is printed, I expect there will have been more sightings.

Known for its vibrant blue and pink colors, Portuguese Man-o-War has a gasfilled bag on top with tentacles that can extend up to 30 feet in length. During the day, the Man-o-War tentacles coil up, and appear thicker and shorter, but when they fish for prey at night, the tentacles extend out further, difficult to avoid for a swimmer.
