Thousands of Jellyfish Are Dying Worldwide, And ‘The Blob’ Could Play a Role


Like a tourist on a cruise ship, the by-the-wind sailor jellyfish (Velella velella) spends its days drifting aimlessly through the open sea, gorging itself on an endless buffet of complementary morsels.

 

The jelly straddles the ocean’s surface with a rigid sail poking just above the water and an array of purple tentacles dangling just underneath. As the sail catches wind, the jelly floats from place to place, capturing tiny fish and plankton wherever it roams.

Thriving Velella colonies can include millions of individuals, all just partying and chowing down together in the open water. Life is good.
