Japanese jellyfish

Japanese sea nettle:
Jellyfish, which have inhabited the world’s oceans in one form or another for over one billion years, come in a dizzying array of shapes, sizes and colors. One species commonly found in Japanese coastal waters in spring and summer is the Japanese sea nettle (Chrysaora melanaster). When full grown, this jelly can reach up to 1 meter (3 ft) in length with an umbrella measuring 20 centimeters (8 in) in diameter.

The Pacific sea nettle (Chrysaora fuscescens)
is one of the world’s largest jellyfish, with an umbrella that typically measures up to 50 centimeters wide and tentacles that stretch up to 2 meters (6.5 ft) in length. It has a moderate to severe sting that can cause welts to form.

The moon jelly (Aurelia aurita)
is probably the world’s most widely distributed jellyfish. It is quite commonly found along the shores of Japan. Although it is composed of more than 95% water, it has an amazing ability to quickly heal itself, even after severe injuries. The moon jelly typically grows to a length of 15 centimeters (6 in) from the top of the umbrella to tip of the tentacles, with a diameter of 30 centimeters.

Spotted jellyfish:
Though mainly found in the southern Pacific Ocean, the spotted jellyfish is active in Japanese waters from summer to autumn. When full grown, this jellyfish measures about 50 centimeters (1 ft 8 in) from top to bottom and 15 centimeters (6 in) wide.
