Appearance: Has a reddish-orange bell with white oral arms and 24 thin red-maroon tentacles
Range: Primarily the U.S. West Coast during summer and early autumn
Habitat:
Near-shore waters
Diet: Zooplankton (small organisms that drift in the ocean), crustaceans, pelagic snails, comb jellies, fish eggs/larvae, other jellies

Crystal jellyfish

Size: Bell grows up to about 10 inches in diameter
Appearance: Clear bell which can give off a green-blue glow around the rim. Long, thin tentacles.
Range: Bering Sea and Pacific Ocean along the West Coast of the U.S. and Canada from Alaska to California
Habitat:
Coastal bays
Diet: Crustaceans, zooplankton, other jellies, and larvaceans.

Fun fact: Crystal jellies' green fluorescent protein, or GFP, is used as a biological marker that's instrumental in medical research. For example, it allows scientists to see how cancer spreads in living cells.

Size: Bell grows up to 12 inches, with tentacles up to 10 feet long.
Appearance: Light-colored bell with dark orange lines radiating in a sunburst pattern from the center.

Diet: Small plankton, like molluscs, crustaceans, fish eggs and other small jellies
