Jellyfish populations are on the rise and marine expert Lisa-ann Gershwin says that is really bad news for oceans and their inhabitants.
The invertebrates thrive in dire ecological situations, and overfishing, warming temps, and acidification are giving them an increasingly ideal environment for proliferation.
A remarkable thing about jellyfish is that even though they’re brainless, they manage to make a meal of far more advanced life forms.
Even whales have to be on the lookout. They may not be under threat of direct attack, but they and the jellies share a lot of food sources.
Says Gershwin, “So jellyfish can wipe out a whole food chain by eating down at the bottom, and they’re doing this.”
An aggressive jelly species was accidently introduced to the Black Sea in the 1980s, and within a couple of years constituted 95 percent of the body of water’s population.
Clearly, that happening to the oceans would be really, really bad.
About 3 and a half billion people rely on food from the oceans.
Only a small number of jellyfish are edible. Reportedly they’re labor intensive to prepare and not all that tasty otherwise.
