Size – Up to 10 inches (25.4 cm) in diameter
Crystal Jellyfish are nearly transparent and bioluminescent, meaning they have the ability to emit light. They are also well known for their Green Fluorescent Protein (GFP) which exhibits a bright green light when exposed light in the range from blue to ultraviolet.
They have up to 150 delicate tentacles, which are covered in nematocysts that are used to capture prey, though harmless to humans, unlike the Box Jellyfish.
These graceful jellyfish can be found both nearshore and offshore in the eastern Pacific Ocean typically ranging from Southern California up to Vancouver.
They eat small crustaceans, but also enjoy comb jellies and other hydromedusae (another class of Jellyfish)
Crystal Jellyfish belong to the genus Aequorea, of the family Aequoreidae, in the order Leptothecata.
There are around 30 species of Aequoreidae and nearly 2,000 species of Leptothecata.
