Tompot blenny (Parablennius gattorugine), Arrábida National Park, Portugal. Note: no FP of this species. It can be found in shallow, coastal waters off western Europe, the Mediterranean and North Africa. The tompot blenny is a relatively large blenny that can grow up to 30 centimetres (12 in) in length. There is a single branched tentacle over each of its eyes. It's very territorial and their territories are centred around a crevice in the rocky reef which the fish uses for shelter. They occur in shallow seas at depths of 3–32 metres (9.8–105.0 ft). It has sharp, comb-like teeth which they use to scrape food from the substrate. They feed on sea anemones[ and on other invertebrates such as prawns and other crustaceans. They are crepuscular, being active mainly at dawn and at dusk.
