This is it - the last of our Jellyfish Overlords series. Today we're featuring Salps, Larvaceans, and Pyrosomes AKA your long lost pelagic cousins.

This week, we're introducing Polyorchis penicillatus (a.k.a. the bell jelly). This gorgeous jelly was once common, but now its medusae are as elusive as the mystery of its polyp stage.⁣

Season 1 may be over on the main feed, but we've got a few more overlords for you yet! If you're familiar with your ocean fauna, you may have already heard of the order Siphonophorae, the Portuguese Man 'O War being the most famous member. Listen to learn more about this big, weird, stingy, stringy gang of sea goop.

We're back with more Cubozoans! Presenting the infamous Irukandji, which is a complex of similar species. These tiny box jellyfish pack a punch like no other, but you're not likely to see them coming. Listen and find out why you should take beach closures seriously.

Ctenophora! A diverse group of otherworldly beauty. These are the comb jellies, named after the rows of cilia they use to hum through the water. Today's mini-episode is a dive into the phylum Ctenophora.

We're back into our species dives with one jellyfish that opened the door to new era of genetic engineering, at its own peril. Meet Aequorea victoria, and its very special protein - GFP.

Meet a surprising little jelly: Bazinga reiki. Take a few minutes to learn about the strange and beautiful food strategy of this little trickster.
