Ponyfishes in the Family Leiognathidae uniquely possess a complex bioluminescent system with an esophageal light-producing organ containing bioluminescent bacterial symbionts, a reflective gas bladder...

Chimaeras (Holocephali) are an understudied group of mostly deep-ocean cartilaginous fishes (Chondrichthyes) with unique characteristics that disti...

Teeth have been a prominent feature of most vertebrates for 400 million years, and the core regulatory network underlying embryonic tooth formation is deeply conserved. In frogs, however, odontogenesi...

Sharks are masters of tooth regeneration with a rapid and unlimited tooth supply. We present a comprehensive transcriptomic analysis across five distinct compartments from the embryonic shark mouth, c...

A fluid preserved Sandbar Shark, Carcharhinus plumbeus, from the Florida Museum of Natural History Ichthyology Collection (UF 108719). This specimen is a fetus that has a spinal column deformity. O...

In the half a century since Jaws was released we know so much more about sharks’ amazing biology.

A shark expert, whose own curiosity about these fascinating fish was sparked by the movie "Jaws," explains some of their unique features and the many discoveries made in the decades after its release.

Whenever Yara Haridy, a paleontologist at the University of Chicago, shows off the fossils she works with, people are often disappointed. Unlike the statuesque bones of dinosaurs or even the small spi...

Teeth are good for chewing and biting, but they are also sensitive – and that may have been their original function hundreds of millions of years ago

The tooth, the whole tooth and nothing but the… frog? – the not-so bite-sized mystery of frog tooth re-evolution 🐸🦷

Teeth have been a prominent feature of most vertebrates for 400 million years, and the core regulatory network underlying embryonic tooth formation is deeply conserved from fishes to amniotes. In frog...

Abstract. Neotropical leaf-nosed bats (family Phyllostomidae) underwent an impressive adaptive radiation characterized primarily by the diversification of

Crocodile head scales self-organize through purely mechanical compressive skin folding rather than a patterning process controlled by gene interactions.
