British record: 2oz (85g) - This blackish, smooth-bodied, thick-set aggressive little catfish rarely exceeds 12in in length. It has a broad head and a wide mouth sporting eight barbels in all, four on its snout and four beneath the protruding lower jaw. It has a tiny adipose fin and a large, squared-off tail. Bullhead catfish spawn in summer, and the resulting fry, which hatch in 5-6 days, are guarded by one of the parents. It feeds on crustaceans, molluscs, small fish and amphibians, and exists only in very localized waters in England. It is widespread in Europe, especially France.
