Do shark brains differ between different species? Does one species' brain change over its lifespan? How does changing environment change brain development? These are questions @ProfSharkBrain and @YopakZoMBiELab are trying to answer!

#DidYouKnow that @ProfSharkBrain and @YopakZoMBiELab have seen 180 species of skates, rays, sharks, and chimera brains? Learn about what she and her Zombie Lab are learning about these brain specimens on the Gills Talk podcast!
Had such a great time on the @GillsClub podcast talking all things 🦈 🧠
We have a new episode of Gills Talk with @ProfSharkBrain herself! Learn if sharks are smart and if that is truly a term we should use to describe their brains! @YopakZoMBiELab

Great to be visiting @ProfSharkBrain of @YopakZoMBiELab at the Centre for Marine Science in Wilmington, North Carolina, talking shark brains & endocasts 🦈 🧠

Understanding repro mode evolution in sharks and rays we can test different theories about how these traits relate to diversification dynamics (i.e. rates of speciation and extinction): the Viviparity Driven Conflict Hypothesis and the Novel Ecological Opportunity hypothesis.
Kara Yopak retweeted
Live-bearing and matrotrophy co-evolved with increasing body size, shallower depth, and more tropical distributions. Larger maternal body size accommodates retained embryos, and increased foraging efficiency with reduced predation risk may allow for more maternal investment
Kara Yopak retweeted
Egg-laying is ancestral and live-bearing and matrotrophy (additional maternal nourishment beyond the initial yolk) have evolved multiple times. While some groups are invariant (all skates lay eggs), groups like the requiem sharks exhibit diverse reproductive modes and habitats
Kara Yopak retweeted
The sequence and drivers of the evolution of live-bearing and matrotrophy are fundamental questions in vertebrate macroecology, and sharks and rays with their reproductive diversity (everything from egg-laying to placentas) are an ideal group for addressing these questions.

Hot off the press! Out now in @CurrentBiology "Maternal investment evolves with larger body size
and higher diversification rate in sharks and rays"

I am today's Roer seminar speaker @UNCW_BaMB, at 3 PM excited to see you all there!

Do sharks have ears? Unlike us, sharks have no need for external ears. Instead, they feel the sound with their whole bodies! In this episode, Dr Lucille Chapuis talks to us about the fascinating topic of shark hearing!

We really can't. Sounds fantastic!

Interspecific Variation in the Inner #Ear Maculae of #Sharks

ALT Fig. 2. Tracings of the saccular maculae from three representative shark species, M. lenticulatus (A), I. oxyrinchus (B), and S . g riffini (C), demon- strating the similar shape of the saccule and similar HC orientations (arrows indicate orientation) between species. Note that length and width should not be directly compared, as scales differ. Scale bars = 1000 μm. D = dorsal, R = rostral.
Can you imagine a better weekend than dissecting shark noses with @OceanExplauren and Aubrey?? Yeah, I can’t either… 🦈🧠

A great 2 days of #SharkSnootScience with Aubrey and @ProfSharkBrain in the @YopakZoMBiELab 🦈🧠
Sampled 18 shark noses including 7 new species for me: bronze whaler, Australian swell shark, school shark, smooth hammerhead, blue shark, shortfin mako, and a FREAKING SEVENGILL!!!

So honored and excited to be interviewed by @isla_hodgson for the @saveourseas #worldofsharks podcast! We had so much fun discussing all things brain - come visit our lab soon Isla!!

So excited to see this work in print! PHD student @derek_sauer looked at variation in the inner ear hair cells across species. Awesome collab with #craigradford @YopakZoMBiELab @UNCW_BaMB
Because every week should be #SharkWeek 👍

Hot off the press! @derek_sauer quantifies variation in elasmo inner ears. Considerable variation with habitat and prey type. Presented @ElasmoSociety last week and published this week! @ProfSharkBrain #craigratford
