Your loving friend,



The Lion’s Mane Jellyfish is the largest jelly species in the world. With tentacles up to 37 metres (120 feet) long, some individuals even rival in size the Blue Whale, the largest animal in the world! Most Lion’s Mane Jellyfish live in the Arctic and North Pacific Ocean, where the waters are cool. This jellyfish harbours a powerful sting that it uses to catch its prey but which can be very painful to humans, and also possesses bioluminescent abilities, meaning it’s able to produce its own light and glow in the dark underwater.
