3. Jellyfish are soft because they are 95% water and are mostly made of a translucent gel-like substance called mesoglea. With such delicate bodies, jellyfish rely on thousands of venom-containing stinging cells called cnidocytes for protection and prey capture.

4. Plastics & litter that make their way into our oceans are swiftly carried by currents, ultimately winding up in huge circulating ocean systems called gyres. The earth has five gyres that act as gathering points, but the largest of all is known as the ‘Great Pacific Garbage Patch’ and has grown so immense that the oceanic garbage patch can shift from around the size of Texas, to something the size of the United States.

5. The 200 or so species of octopuses are mollusks belonging to the order Cephalopoda, Greek for ‘head-feet’. Those heads contain impressively large brains, with a brain to body ratio similar to that of other intelligent animals, and a complex nervous system with about as many neurons as that of a dog.

6. Some lucky animals are naturally endowed with bioluminescence, or the ability to create light. The firefly, the anglerfish, and a few more surprising creatures use this ability in many ways, including survival, hunting, and mating.

7. Sea turtles ultimately grow from the size of a dinner plate to that of a dinner table. In the case of the leatherback sea turtle, this can take up to a decade. Happy World Turtle Day!

‘It’s 3.23 in the morning and I’m awake, because my great-great-grandchildren won’t let me sleep.
My great-great-grandchildren ask me in dreams
“What did you do while the Planet was plundered?
What did you do when the Earth was unravelling?
Surely you did *something* when the Seasons started failing?
As the mammals, reptiles, birds were all dying?
Did you fill the streets with protest when Democracy was stolen?
What did you *do* once you knew?”
