Ynghylch

Britain’s largest goby, this giant of the rocky shore spends most of its time hiding in crevices and very little is known about their behaviour. It is thought that females can lay up to 12,000 eggs in small crevice ‘nests’, which males will then guard attentively. Giant gobies can change colour depending on mood and surroundings.

What to look for

Giant gobies are very large fish to find on the shore and have a large head and chunky body. Characteristically they are salt and pepper speckled colouration with small and well spaced eyes. Dark blotches appear along the mid-line of the body.

Where to find

South West England only, from Wembury in Devon to the Isles of Scilly. Also found in the Eastern Atlantic, Mediterranean and Black Sea.
