On January 22 from 2:30 pm until 4:00 pm, visitors aged 55 or older are invited to @uamnh's Grand Gallery for a free event to learn how to recognize local birds through size, shape, and color and how to use bird watching tools! REGISTER: ➡️ bit.ly/40ilGeTamnh

The Alabama Museum of Natural History is thrilled to partner with @kulturecity to enhance our ability to assist and accommodate guests with sensory needs. Our goal is to provide an inclusive experience for all guests during all events.

More groundwater biodiversity…. I am thankful for the world's blindcats, here are three species: The Mexican Blindcat (Prietella phreatophila) -top, the Brazilian Blindcat (Rhamdiopsis species) –middle, the Chinese Blindcat (Xiurenbagrus dorsalis) –bottom.

Welcome back to #Fossilfriday Here is the partial calyx of the crinoid Platycrinites huntsvillea. This specimen comes from the Lower Carboniferous (Upper Mississippian) Lower Monteagle Limestone Formation in Alabama. The arms and pinnules are decently preserved.

Happy fossil Friday everyone! Here is a bony head plate of a giant catfish from the Miocene Pebas wetland system of Peru. Believed to be roughly 13 million years old, recovered from the Napo River.

Big news everyone! After a few months undergoing an extensive renovation, the @calacademy Twilight Zone exhibit reopened today! And it looks fantastic! Some amazing new stars were added, and our old friends are doing great. Come check it out if you are in San Francisco!

🥳Exciting News! We've just described 8 new catfish species from central and southern Africa's rivers 🐟 @ZoolJLinnSoc @NRF_SAIAB doi.org/10.1093/zoolin… saiab.ac.za/revealing-hidd…

Paper alert 🐠!!! We investigated the evolutionary patterns of seahorses, goatfishes, dragonets, flying gurnards (Syngnatharia) across different oceans. journals.uchicago.edu/doi/10.1086/73…

The final version of our paper is out: Phylogenomic and anatomical evidence for the Late Cretaceous diversification of African characiform fishes, including a new family, under the influence of the Trans-Saharan Seaway: doi.org/10.1093/evolin…

I'm hiring a coordinator for our #mesophotic Autonomous Reef Monitoring Structures (ARMS) program! This exciting new project will generate unprecedented amounts of information about the biodiversity of deep reefs in the Pacific. Spread the word! us242.dayforcehcm.com/CandidatePorta…

Very pleased that my new paper on darter cranial musculature is out now in the Zoological Journal of the Linnean Society. Some surprises compared to Perca, and more anatomical diversity than I was expecting! #teamfish #diceCT

Ghost shark, chimaera, spookfish, ratfish, this group goes by many names! This is the subclass holocephali, the sister class to elasmobranchii, which is the group of sharks, skates, and rays. Specimens in this video collected with permits

Excited to share our newly published study in @SpringerCORE following fish and coral richness and composition across a year using #eDNA on a model coral reef at Lizard Island, only possible with generous funding from @lirrf. In short, summer is where it's at on the reef!

From a very common Anthias that is often seen by divers to another common one that is rarely seen. The One-Stripe Anthias (Pseudanthias fasciatus) is widely distributed and common, but rarely seen shallower than 50m depth. I photographed these two beautiful females at about 80m.
