Spring breakers heading to Texas beaches this month might encounter a stunning yet potentially hazardous visitor: the blue dragon, scientifically known as Glaucus atlanticus. These vivid blue and silver sea slugs, though small at just one inch long, have been stirring concerns among beachgoers.
Researchers warn that while the blue dragons appear playful, touching them can result in a painful sting. These sea slugs thrive by preying on toxins released by the Portuguese man o' war and other jellyfish-like species. As southeastern winds pick up in spring, these slugs are swept ashore, bringing with them the risk of harmful chemicals that can affect unsuspecting visitors.
\"Warning: Do not touch the blue dragon!\" urged Jace Tunnell, a marine biologist from Texas A&M University-Corpus Christi and Harte's director of community engagement, in a Facebook post. Speaking to BBC, Tunnell explained that blue dragons are pelagic nudibranchs that sail on the ocean's surface. They consume the tentacles of larger species like the Portuguese man o' war, which can have tentacles extending over 30 feet long.
Tunnell added that blue dragons not only eat these tentacles but also remove their stinging cells, storing them in their feather-like appendages. This allows the slugs to use the stingers defensively when they feel threatened.
Despite their beauty, experts advise beach visitors to admire blue dragons from a safe distance. \"Look and don't touch,\" they caution, recommending that visitors photograph these magnificent creatures without direct contact to ensure a safe and enjoyable beach experience.
