The rather grandly named leopard-spotted goby, Thorogobius ephippiatus, is a very distinctive blue/grey colour becoming a faint reddish or pale orange colour towards the head. The body has a number of large dark spots. All of these features combine to make this fish easy to distinguish from all other gobies. It lives in rock crannies and seems in some locations to prefer those in silty areas. It can be found just below low tide mark where it feeds on small worms and crustaceans. It can be seen all round the rocky coasts of the UK where it grows to a length of about 13cms.
