The ankheg is a large and intimidating creature, with a broad, chitinous body that is covered in a hard exoskeleton. Its head is triangular and elongated, with a pair of mandibles that are capable of delivering powerful bites. Its eyes are small and beady, and it has a pair of long, flexible antennae that it uses to sense its surroundings. The ankheg is a burrowing creature and is often found in underground tunnels or caverns. It has a voracious appetite and is known to prey on anything that it can catch, including animals, plants, and even other creatures. Despite its fearsome reputation, the ankheg is not inherently aggressive and will only attack if provoked or threatened.
