Hi again. It’s been a while since I’ve done one of these, but now that I’ve got internet, I’m back here on a Saturday to bother you with all of the environmental news I found interesting this week. There was a lot that went on this week, what with it being World Environment Day on Monday, Canadian Environment Week, and World Oceans Day on Thursday. Outside of all of that, there were ancient birds, Macron trolling Trump, and whales in NYC. So let’s dive in! Continue reading
What?!?!?!? A new Weekly Round Up? But we haven’t had one of these in weeks??? After dropping the ball for a few weeks, it’s back baby, in all its glory. I’ve scoured the internet and grabbed for you a group of environmental news stories that I think you’ll enjoy. I’m talking fish eyeball parasites, CRISPR-HIV research, and a pretty damn cool cuttlefish battle. So let’s dive in! Continue reading
Cephalopods (aka octopuses, squid, and cuttlefish) are some pretty interesting creatures. Essentially called head-feet (cephalo mean head in greek, pod means feet), cephalopods are some of the smartest invertebrate species out there, and definitely some of weirdest. Ignoring the fact that they have feet where you’d expect their noses to be (which is weird in its own right), their ability to rapidly change the colour and -in octupuses and cuttlefish- the texture of their skin is even weirder (especially considering that they’re mostly colourblind).

Cuttlefish are one of the coolest marine creatures out there! And they aren’t actually even a fish at all, but a mollusc. There closest relatives include squids and octopuses; and they are found in mostly-shallow tropical waters off almost all coasts except the Americas.
The first cool thing about cuttlefish, though, is that they have a unique body part, the cuttlebone. The cuttlebone is an internal structure made from aragonite, a natural crystalized version of calcium carbonate. The cuttlebone keeps the cuttlefish buoyant, by changing the gas-to-liquid ratio within the cuttlebone. So let’s talk about them. Continue reading
