Season 3

The Mola mola, aka Ocean sunfish, breaks every fishy rule – it has no tail fin, can grow to two tons, and survives on a diet of jellyfish. Sarika unpacks how this massive, odd fish pulls it all off.

The ultimate climbing showdown: human versus mountain goat. Anthony and Sarika team up with pro climber Yves Gravelle and a mountain goat expert to find a champion.

Madison McKay (aka Nudibranch Nerd) joins Sarika and Anthony to nerd out over what might be the greatest thieves in the animal kingdom: sea slugs.

Anthony and Sarika dig into the chemistry (and pain) of spice, discovering how garlic, wasabi and the world’s hottest pepper all play tricks with your senses.

They might not look it, but sea stars are some of the ocean’s most efficient and voracious predators. Sarika tries to convince Anthony to watch out for these slow-moving killers of the sea.

Anthony asks Sarika his favourite hypothetical questions about relationships and shared bacteria (the messier and more unhinged the better) to see if real science can change their minds.

From the Egg yolk jellyfish, to the Chocolate Chip sea star, the ocean is full of animals named after food. Sarika reveals the wild biology behind these culinary creatures.

Anthony and Sarika pit some of the animal kingdom's hardest hitters against an arcade punching machine to see what kind of score they'd rack up.
