Lion's Mane Jellyfish
(Cyanea capillata)

The color of these jellies varies with their age, ranging from dark reddish-brown to pinkish-yellow. In southern New England, they are usually 6-12" (15-30 cm) in diameter but further north they can grow to 8' (2.5 m) in diameter. They have long yellowish-orange tentacles and lobes surrounding the mouth (called oral arms) that are attached to the underside of the umbrella and resemble a lion's mane. They have stinging cells (nematocysts) that are mildly toxic. This jellyfish is very common in local waters in the summer.
