A sea nettle is a type of stinging jellyfish found in both the Pacific and Atlantic oceans. Translated, Chrysaor means "he who has a golden armament." Each sea nettle tentacle is coated with thousands of microscopic cnidocytes; in turn, every individual cnidocyte has a "trigger" (cnidocil) paired with a capsule containing a coiled stinging filament. If the sexual reproduction happens a phase called strobilation will occur. Sea nettles are also able to consume minnows, bay anchovy eggs, worms, and mosquito larvae. This keeps unfired nematocysts from firing and adding to the discomfort.[3]. APPEARANCE: The Atlantic sea nettle is a translucent white and can sport brown, red, or purple stripes.
