A taxonomic framework for typhlopid snakes from the Caribbean and other regions (Reptilia, Squamata)
, 2014 The evolutionary history and taxonomy of worm-like snakes (scolecophidians) continues to be refined as new molecular data are gathered and analyzed. Here we present additional evidence on the phylogeny of these snakes, from morphological data and 489 new

The Anatomical Record, EarlyView.Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.

The Anatomical Record, EarlyView.Abstract The pygmy sperm whale (Kogia breviceps) possesses an exocrine gland associated with its false gill slit pigmentation pattern. The cervical gill slit gland is a compound tubuloalveolar gland that produces a holocrine secretion and displays maturational changes in size and secretory histology. While the morphology of the cervical gill slit gland

Globally centered discrete snakes [PDF]
arXiv, 2006 We consider branching random walks built on Galton-Watson trees with offspring distribution having a bounded support, conditioned to have $n$ nodes, and their rescaled convergences to the Brownian snake. We exhibit a notion of "globally centered discrete snake'' that extends the usual settings in which the displacements are supposed centered.

The Anatomical Record, EarlyView.Abstract Neuroanatomy studies in vertebrates have garnered significant attention in recent years, particularly driven by advancements in computerized tomography imaging techniques. Nonetheless, these advancements remain largely constrained to specific vertebrate groups, notably mammals, birds, and fish, leaving studies in reptiles at an incipient stage.

Report on occurrence of Yellow Sea Snake Hydrophis spiralis off Kerala coast [PDF]
, 2015 Sea snakes play an important role in the marine food web and studies on their diversity and distribution are very limited in India. Globally, 70 species of sea snakes have been reported under the family Elapidae which is divided into two subfamilies

Sharpening our understanding of saber‐tooth biomechanics
The Anatomical Record, EarlyView.Abstract Saber‐teeth are a striking example of convergent evolution in vertebrate predators, having evolved multiple times in mammals and their early ancestors. While there is broad consensus that saber‐toothed taxa employed a distinct biting strategy compared to conical‐toothed carnivores, like the lion, the precise mechanics and variability of this ...
