Ichthyology is not easy to say, but fish are easy to love. Dr. Chris Thacker will get you so thrilled to stare into a pond or look up pictures of silvery sea serpent-looking fish friends.

Hilariously charming fish expert and LA County Natural History Museum Curator of Ichthyology, Dr. Thacker took Alie to a basement full of several million jars of fish to chat about the worst fish husbands, the weirdest mating behaviors, the scariest fish, the nicest fish, the tiniest fish, how they breathe, how you can help reverse global warming, and whether you should pee in wetsuits. I love her so much and so will you.

Glaciers: Where are they? What are they made of? What happens when chunks splinter off into the sea? There are ICEQUAKES? CalTech Cryoseismologist Celeste Labedz sometimes wears a cape with her snowpants and spends part of her career shooting explosions into giant chunks of ice and recording the seismic activity, analyzing the rivers that flow through glaciers, and keeping tabs on glacial melt.

Alligators! Crocodiles! The excitement never ends when you’re Laura Kojima, an Alligator Ecotoxicologist. A longtime reptile cheerleader, Laura has passion to match some truly bananas stories about field work, what an alligator will do for its favorite snack, crocodilian evolution, overbites, crocodile tears, locomotion and so much more.
