Carapede

The carapede split from its ancestors. Because of competition with other krillpede species, it has became a scavenger; feeding on both dead flora and fauna. They have evolved a tough, bivalved carapace on its back to protect it from predators like the anomalogill. Meanwhile, its silver-colored body acts as a secondary defense, as it is somewhat reflective. The light glinting off of the shell is able to make it hard for predators with eyes to see them. While the first two segments behind the head now have three legs, the rest of the segments' legs have atrophied away. The segments with the legs are hidden under the carapede's large shell, protecting them from predators. In order to fit the extra legs, the carapede's segments have grown longer. It now uses both its legs and tail to swim. It never swims far from the sea floor, as that is the where corpses and dead flora are most common. Their beak has lost its baleen and has became sharper to aid it in biting into its new food. Those that swim too far up into the water column often fall prey to the necroeel; as it has no problem biting through their tough carapiece. In addition, the necroeel has no eyes, making it immune to the carapede's reflective shell.
