I hate these guys so much . They are an EVIL and most Annoying creature on the ocean . Yesterday there are pack of these guys came to my underwater zone . My tames came ti attack it , but they are fully tranquilized . I use my Pike trying to kill them . I kill 2 of them but there is 1 of these guys that has high level . It killed My Megalodon and Crocodilie (Sarco) . I died too , I was really sad and ride My Bronto to the water and attack this Jellyfish monster . I recommend if you see these guys , Bait them near the Surface and kill them with Ranged weapons . Rip Megalodon and Crocodilie
