It appears as a floating corpse such as a human skeleton or decaying fish. When you realize something is off- a mailed skeleton shouldn't be floating, or the carcass is encased in a crystal clear coffin of gelatin- it disgorges its contents at you along with a sticky fluid. They are impossible to spot from underwater, as they hold their contents above the surface. Rarely, a malformed, 'tall' coffin jellyfish will hold its contents upright, giving the appearance of a ghastly levitating body, drifting ever closer over the surface of dark waters. This horse-sized jellyfish thrives in freshwater or seawater. Capable of tipping over fishing vessels, it often succeeds in dumping victims directly into its maw. Prey in the water is captured in a forest of tendrils. Both suffer the same fate. Held beneath the water, air-breathers drown quickly, to be digested later. Fish and their ilk are little better off, as gelatinous flesh suffocates them. Satisfied with a single man-sized meal, a coffin jellyfish will likely try to slowly flee after engulfing one person. Instinct: To feed slowly on drowned flesh

• Appear as a floating corpse
• Vomit corpses at them
• Rock or capsize small boats
• Engulf living flesh into its gelatinous body
