The rise of jellyfish populations in many of the world's oceans may be more than just an inconvenience for swimmers who want to take a dip.
The rapid growth over the last few decades of these creatures is a sign of the planet's deteriorating marine health, according to expert Lisa-ann Gershwin.
In her new book Stung! On Jellyfish Blooms and the Future of the Ocean, Gershwin says that these "enchanting and lovely" invertebrates are in fact harbingers of the health of the oceans.
"They're an indicator that something is out of balance,” she told Bob McDonald, host of CBC Radio's Quirks & Quarks. “So they’re kind of the canaries in the coal mine, if you will. Except whereas a canary dies when something’s wrong, jellyfish flourish when something’s wrong.”Read the whole article about the ocean's ecosystem being unbalanced by following the link below
