Hemogoblin Shark

The Hemogoblin Shark is a Hardmode enemy that can be spawned by fishing during a Blood Moon event. When the bobber dips and the player attempts to reel in a fish, a Hemogoblin Shark, among other enemies, has a chance to spawn within a few blocks of the bobber in place of a fish. The Hemogoblin Shark can move incredibly fast on land, swim quickly in water, jump very high, and can use a ranged blood vomit attack. This makes it a dangerous enemy for those starting out in Hardmode.

Tips

 * Building a platform high above your fishing spot allows you to dodge the Hemogoblin Shark's lunging attacks, though it can still hit you with its blood spit attack.
 * The Flying Knife is an effective weapon if the Hemogoblin Shark gets stuck in a crevice.

Trivia

 * The name 'Hemogoblin Shark' is a portmanteau of "hemoglobin," an oxygen-carrying protein found in vertebrates which is responsible for giving blood its red color, and "goblin shark," a rare and ancient species of shark native to the deep waters of the Eastern Atlantic.
 * The Hemogoblin Shark's Bestiary entry — "Half-shark, half-goblin, completely murderous!" — references the Minishark's tooltip.
 * Although it is not part of the Old One's Army event it still has Attacker AI.
 * It is the only non Old One's Army event enemy to have Attacker AI
