BUXTON, N.C. (WAVY) — Venomous sea slugs have been spotted in the Outer Banks, according to Cape Hatteras National Seashore. Known as blue sea dragons, these slugs live in the ocean and occasionally get washed ashore by strong winds. Cleanup continues on 2 collapsed homes on the Outer Banks Seashore advises visitors to admire the creatures from a safe distance and to be cautious that more could be nearby because they can travel in groups. The slugs are only one inch long and primarily feed on the highly-venomous, Portuguese man o' war jellyfish. They are capable of storing the jellyfish's venom for their own defense. It should be noted that blue sea dragons remain venomous even after they are dead. If you've spotted these creatures on Outer Banks beaches recently, please let us know.
