The unusual-looking fish, which has a giant head and sharp spines on its fins and gills, was caught by Josh Dearing just inside St Brelade’s Bay.
The 24-year-old said: ‘I’ve seen a few of them while diving, but they are quite rare.’
Mr Dearing, who owns The Jersey Catch, a local company which uses ethical and sustainable fishing methods, returned the colourful creature to the sea.
Short-spined sea scorpions are fairly common in British seas but, as they usually live in deep waters, are rarely caught.
They have a very large mouth and head compared to the size of their body and can grow up to 3lbs.
Sea scorpions are aggressive feeders, often devouring fish similar size to itself.
