It is about deep sea creaturs fighting for there prey or going head to head.One of my favorite sections is toxic shock and in there is blue for danger trail of death starfish plague which you will have to find out about.my also favorite is feeding frenzy and these fish rip apart other fish and munch on it. Also these fish have big and wide teeth that can pierce though humen skin and bones and fish flesh.also it talks about diffrent parts of the ocean.
