Unlike all other mammals, seals can hear both in the air and underwater. How do they do this? @Blogozoic @Palaeo_JRule @ian_g_brennan @OurANU @MonashUni theconversation.com/seals-ha…

Seals have a unique superpower in their ears, and we finally know how it evolved

Very happy to have worked with @Palaeo_JRule and all our coauthors in this huge effort of a paper! He’s done an amazing job pulling this together over the last few years.

Seals have a superpower: they are the only mammals with amphibious hearing! They hear well both in-air and underwater. My collagues and I have a new study in Proceedings B on the origins and evolution of amphibious hearing in pinnipeds 🦭🔊🧪 doi.org/10.1098/rspb.2026.01…

The origin and evolution of amphibious hearing in pinnipeds

Abstract. Pinnipeds (true seals, eared seals and walruses) are the only mammals that can hear effectively in both air and water. How and when they achieved

New paper out today, led by my PhD student @Inxcetus, naming a new species of toothed baleen whale. Fantastic work (including the artwork) from Ruairidh, a lot of effort has went into this one! Find out more in the thread below.

1/ A few years in the making, but I can finally share my first PhD paper and my first ever first-authored whale paper. In it, we name a new species of toothed baleen whale: Janjucetus dullardi. You can find our conversation article here: tinyurl.com/dullardi

For this #FossilFriday I'm happy to present my latest paper, written with @MaryViglino. We wanted to know if the convergent evolution that river dolphins display in their external morphology extends to their inner ears. Turns out, it doesn't! royalsocietypublishing.org/d…

River dolphin cochlea has not evolved convergently

Abstract. Convergence is often invoked to explain some common morphological features in the crania and postcrania of river dolphins (Cetacea, Odontoceti).

Cochlear analysis of Kekenodon onamata, a late Oligocene stem whale, suggests they specialised in low-frequency hearing, a trait of raptorial feeding in fossil whales. Low-frequency hearing may be characteristic of raptorial macrophagous fossil cetaceans @joshcorrie @Blogozoic
