bream, dogfish, ling, rockfish, wrasse, conger eel, porpoises ("sea pig" and "sea bonham" – the meat being described as "pork"), seals, crab, lobster, crayfish, limpets, winkles and mussels, as well as seaweeds such as dulse, sea lettuce, sea belt, and murlins. Many on the island relished seal meat much more than pork. One night Ó Criomhthain and colleagues caught a "huge creature" in their nets with great danger and difficulty. Perhaps it was a whale or basking shark. Oil from the liver of this unidentified "great beast" fuelled all the lamps on the island for five years (there were about 150 people in fewer than 30 households).
