Stalking Murkworm

The Stalking Murkworm is a descendant of the Giant Murkworm. It lives at the ground of the water body from the swamps. It gulps the mud and filters all organic matter out of it. Its front fins evolved into stilts, which it uses to stalk on the ground. The microlungs right behind the first armor merged into one air hole, which is elongated and protected by a long spike, so the Stalking Murkworm does not have to swim to the surface of the water. Because of its way of living, it can't swim as well as its ancestor. When their body of water is drying up, they can get onto land to find the next body of water. But if they do not find one, they will dry up. Because they live in the water and their body is too large to hold its weight on land, they have to crawl by pushing themselves over the land with their stilts.
