The lobster is found in some medieval encyclopedias. They fight with each other, using their claws like rams use their horns to batter their opponent. When they must defend themselves from enemies, they do so in groups. They are seen in such numbers that it it seems they walk in herds. They will eat anything, but live mostly on dung and mud. They have broad tails so they must turn slightly when they fight. They are so terrified of the octopus that they die on just seeing one.
