gains the Sprint ability at 180K XP, where text comes up saying, "Whoa! You have become a Dangerous Shark. Now you can swim faster to chase your prey down. (Tip: Double-tap Boost button (space bar or left-click) to stop running!)"
Sharks are large, bluish-gray animals, featuring two side fins and a dorsal fin on top, as well as an extended snout with small white teeth. They also have a thin, vertical oval for a tail.
Use your Jaws Bite to attack your prey. Press them against a hill; this will force the animal to take extra damage from your bite. They should die within seconds. Another strategy is to force your prey out of the Ocean, where they should thirst to death.
Since your at 180k XP, you can swim fast now, you can hunt prey easier and escape predators easier, Try looking for Pufferfish, Swordfish, Octopus, and etc. You can also swim faster in ink too. (while you use the fast swim) But if you run or escape near a Krakens whirlpool, you wont escape that easily, because the whirlpool lasts for a long time. Bigger whirlpools last even longer.
An easy way to catch prey is using the boost ability to damage prey, then the bite to finish them off if they don't die. It's near impossible to escape.
