Northern sea nettle

Northern Sea Nettle. The jelly's bell can be white to dark purple/red, with dark lines radiating from the top of the bell. Their sting can cause an allergic reaction in some people. Their stinging cells are capable of causing serious skin irritation and burning sensations. Diet consists of plankton, including small crustaceans and other jellies. Bell can be up to 12 inches wide; tentacles can extend as long as 10 feet on giant specimens. Their range is Pacific Ocean, from Japan north to the Bering Sea. Sea turtles and other jelly-eating animals, such as tuna, sunfish, butterfish, and spiny dogfish, keep the jelly populations in balance.
