(left) broods many thousands of planula larvae that make up the white-edging of her oral arms. According to numerous scientists, these blooms suggest that all is not well within the ocean, perhaps something to do with climate change, pollution, overfishing, or a combination of all three. In recent years, there have been reports from all over the world of uncommonly large blooms of jellyfish driving people out of the water, suffocating commercial fish farms and clogging up fishing nets and the intakes of ships and power plants. And while hundreds of people will turn up to rescue a beached whale, few of us would stop to re-float a stranded jellyfish.Īnd yet humans are probably responsible for what seems to be an international jellyfish explosion.

They have a pouch for a stomach that doubles as the reproductive system, a mouth that doubles as an anus, and the rest is mostly water and a bundle of nerves.ĭuring the Renaissance, jellyfish were thought to be plants, and while 18th century naturalists allowed them entry into the animal kingdom, they were initially classified as zoophytes, something between plants and animals. Jellyfish keep things simple: no heart, no brain, no circulatory system and no bones. For shrimps and small fish, pelagic jellyfish of this sort act both as a floating cafe and a predator fence as they drift in open seas. capillata), or-if there are raised gelatinous warts on the (unseen) surface of its bell-the recently-described endemic species of Cyanea.
