    Ep. 132 Crustaceans Pt 2: Everybody Wants to Be a Crab

    Ep. 132 Crustaceans Pt 2: Everybody Wants to Be a Crab

    Hi everyone! In part 1 of crustaceans we laid down a lot of groundwork on what crustaceans even *are*. But here in part 2 we wanted to spend some time talking about a hot topic in crustacean-world: "carcinization" aka "stuff keeps evolving into crabs"! But not *all* crustaceans are yearning for crabdom -- there is a specific group called anomurans that really dig that crab vibe. Learn about them and what it takes to be a crab on this episode of Petri Dish!

    Ep. 131 Crustaceans Pt 1: What the F*** is a Shrimp?

    Ep. 131 Crustaceans Pt 1: What the F*** is a Shrimp?

    Hey everyone! On this episode of Petri Dish we ask the question everyone has been asking since time immemorial -- what the f**k is a shrimp? Like seriously, what is that shit? No, I mean, I ask because there are so many things called shrimp -- fairy shrimp, mantis shrimp, seed shrimp, and so on... And while they look kind of similar to one another, they really aren't all that related, separated by hundreds of millions of years of evolution.

    But they all belong in the big group of animals called 'Crustaceans', along with crabs and lobsters! And insects. Wait, what? Yeah, this group of animals is a total mess, so let's talk about it!

    Ep. 129 Kelp Pt 2: Fixing, Farming, and Filtering

    Ep. 129 Kelp Pt 2: Fixing, Farming, and Filtering

    Part 2 of 3 of our series on Kelp! Part 1 was all about natural kelp forests and how cool they are, but part 2 is focused on how humans can EXPLOIT kelp for our own purposes, muahahaha! Can we use kelp to fix all that carbon we've been releasing into the atmosphere to help us reverse climate change? What about farming kelp for food and products? What about using kelp as a fancy filtration system to clean up water supplies? Find out about all that this week!

    Ep. 128 Kelp Pt 1: Forests Au Naturale

    Hey everyone! This next series of Petri Dish is about Kelp, due to strong demand from Nathan. Kelp are those big floaty plant-looking things (but they aren't plants, technically)! This episode, we dive into natural kelp forests and how they're both environmentally great and also at risk of shrinkage. In future episodes we'll cover kelp farming and the fun uses of kelp!

Kedmoomoo ,

Smart and funny

I trust Sean more than Google. There, I said it. I mean it. But for real, I enjoy science, and I was a scientist for a whole three months (lab assistant) before realize I wasn’t good at it. The podcast explains complex concepts in an easy to follow way without talking down to the listener and making it fun. Thanks guys!

Learn stuff and laugh

These guys do a great job explaining topics in a way that’s entertaining. The digressions and references make the conversation more fun than a lecture. Subscribe now!
