First 30 seconds sets it up. Next 3 minutes is just a basic recap of starfish and lizards breaking off their limbs in response to predators. Final 60 seconds literally just says, "Oh yeah, back to the zombie star fish. It's a virus. We don't know anything else. Bye!"
As Nominal has already pointed out, this documentary is pretty trashy and dumb. Also, I'm not so sure "spitting out your own stomach to digest prey" qualifies as a "super-power". I would think that being able to eat food whole, then digest it safely within the confines of your own body, is the real super-power.
