What is the significance of the tremendous diversity of #shark skin #denticles? Presenting our experimental approach to understanding this at the Atlanta #SICB2025 meetings. Come to the session for all things shark skin!
Toothy skin! Perfectly uniform skin denticles of the juvenile Nurse Shark (Ginglymostoma cirratum). These flat 'skin-teeth' give these sharks a super smooth surface, for drag reduction or relaxing in tropical warm waters? @Ella_Nicklin @FloridaMuseum #shark #skinteeth #denticles
First author paper is out, ft. some pretty uCT scans I've been sitting on! Excited to see this one through with our team. Where do "odontodes" come from? What are they made of? How do they develop and regenerate in #sharks? #teeth #denticles #odontodes #evodevo
New Paper Alert. @Ella_Nicklin leads our new paper in @Dev_Bio_Journal Evolution, development, and regeneration of tooth-like epithelial appendages in sharks. What do all 'odontodes' have in common? Is a tooth, just a tooth? #sharks #teeth #skinteeth

@garethjfraser @NSF @WHOI @MCZHarvard @Ella_Nicklin @aquatic_isa @gigimitchell28 @MarBioMoll @elizabethsibert @UF_CLAS Happy to host such a great meeting @harvard and then to have a second day @WHOI in the lab of @elizabethsibert. So many #shark #denticles, so little time!

With a name like 'Amalgam'....we had to be involved in this project!!!! Working with @aardman we brought to life the 'Denticle' characters they designed in the form of five sculptures for the new @BristolUni Dental School. #wearemakers #bristol #university #denticles #aardman

Hv u ever heard abt “SAWFISH” ??
Here r some amazing facts abt it

Here are some of my favorite SEM (scanning electron microscopy) images I've taken this summer while looking at the denticles of the Pacific spiny dogfish

Beautiful rainbow scan of a spiky Little Skate (Leucoraja erinacea) hatchling imaged with the @KeyenceUSA VR6000 3D-Optical Profilometer, showing the pattern of skin #denticles and large dorsal thorns (aka #skinteeth)! 🌈 🦈 🛼 @UFBiology #flatshark #thornyskate #devbio #evodevo
#Shark #scales (#denticles) accumulating in #sediments can reveal ancient shark communities. Dillon et al. show that denticle shedding rates differ between shark species and shape how denticle accumulation reflects shark abundance
So why is this important? A key reason: #denticles on branchial pouch skin are amenable to experimental measurement in the laboratory. We can measure flow over these denticles in live sharks to understand the relationship between denticle shape and flow.
The amazing skin of sharks: a (longish) thread! For some time we’ve been studying the structure and function of #shark #skin and #biomimetic models of shark surfaces. Covered with amazing dermal #denticles (#scales) sharks have skin with a rough texture composed of tiny teeth.
I wonder if a walking stick bug still cares to flow? 🤔proventriculus denticles #walkingstickbug #vetpath #denticles #entomology
Interested in @cookedillustra's process when creating the graphical abstract to visualize the main points of our recent paper? @IanCookeTapia and I collaborated on a blog post to accompany the graphic: https://t.co/UhyHpRBK2m #scicomm #sharks #denticles #historical #ecology

Many congratulations to @elizabethsibert and @SoundsFishyLeah for the publication of their outstanding paper in @ScienceMagazine on #shark diversity through time using #denticles in deep-sea sediments (https://t.co/frEjpBmRvv). Such weird denticles in extinct species!
Have you ever seen a developing #shark skin denticle (aka skin tooth)? This histological section shows the cellular detail of a denticle still forming under the surface of the embryonic catshark (Scyliorhinus canicula) epidermis. #skinteeth #denticles #devbiol #evodevo 🦈🦷🔬
#Shark skin #denticles are remarkably diverse, but the external skin between gill slits shows a new pattern. @molly_gabler shows a dramatic transition in denticle shape within a few mm in her #SICB2021 talk. #fishsci #sharks #SharkScience @SICB_DCB_DVM
