Vicious Sauceback

The vicious sauceback replaced the golden sauceback. Its hearing has enhanced and its carapace has formed around it to mimic ears, which also protects a much larger brain. Its mouth has greatly improved and now has 4 jaws. This greatly improved its hunting by being able to grab on and hold struggling prey. It has no eyes but can see using its echolocation. It is getting so sensitive, it can "see" around it based upon sound and air pressure. The endoskeleton has improved as well to allow better movement while running. The one micro lung has increased a lot to breathe in more air to fuel the ever increasing brain.
