A rare sky blue lobster has been rescued by an aquarium after being discovered at a fish market.

It was spotted by staff at Viviers Fish Market in Portsmouth, Hampshire, who realised its rarity and contacted the Blue Reef aquarium in Southsea.

The colouration is believed to come from a genetic defect that causes the lobster to produce an excessive amount of a particular protein that turns the crustacean light blue.
