New chromosome-scale genomes provide insights into marine adaptations of sea snakes (Hydrophis: Elapidae)

open access: yesBMC Biology, 2023
Background Sea snakes underwent a complete transition from land to sea within the last ~ 15 million years, yet they remain a conspicuous gap in molecular studies of marine adaptation in vertebrates.

Trophic specialization drives morphological evolution in sea snakes [PDF]

open access: yesRoyal Society Open Science, 2018
Viviparous sea snakes are the most rapidly speciating reptiles known, yet the ecological factors underlying this radiation are poorly understood. Here, we reconstructed dated trees for 75% of sea snake species and quantified body shape (forebody relative

Hydrodynamics of a twisting slender swimmer [PDF]

open access: yesRoyal Society Open Science, 2020
Sea snakes propel themselves by lateral deformation waves moving backwards along their bodies faster than they swim. In contrast to typical anguilliform swimmers, however, their swimming is characterized by exaggerated torsional waves that lead the ...

Ultrastructural evidence of a mechanosensory function of scale organs (sensilla) in sea snakes (Hydrophiinae) [PDF]

open access: yesRoyal Society Open Science, 2019
The evolution of epidermal scales was a major innovation in lepidosaurs, providing a barrier to dehydration and physical stress, while functioning as a sensitive interface for detecting mechanical stimuli in the environment.

Identification and Characterization of a Novel Cathelicidin from Hydrophis cyanocinctus with Antimicrobial and Anti-Inflammatory Activity

open access: yesMolecules, 2023
The abuse of antibiotics and lack of new antibacterial drugs has led to the emergence of superbugs that raise fears of untreatable infections. The Cathelicidin family of antimicrobial peptide (AMP) with varying antibacterial activities and safety is ...

First Record of Laticauda semifasciata (Reptilia: Squamata: Elapidae: Laticaudinae) from Korea [PDF]

open access: yesAnimal Systematics, Evolution and Diversity, 2016
The Chinese sea snake Laticauda semifasciata (Reinwardt in Schlegel, 1837) is newly reported from Korean waters based on three specimens collected from Jeju Island, Korea, in August, September, and November 2015.

Biogeographic origins of the viviparous sea snake assemblage (Elapidae) of the Indian Ocean

open access: yesCeylon Journal of Science, 2017
One of the primary goals in biogeography is to understand how different biotas have been assembled in different regions of the world. The presence of the viviparous sea snakes in the Indian Ocean (IO) poses a unique question in this regard due to their ...

Macroevolution in axial morphospace: innovations accompanying the transition to marine environments in elapid snakes

open access: yesRoyal Society Open Science, 2022
Sea snakes in the Hydrophis-Microcephalophis clade (Elapidae) show exceptional body shape variation along a continuum from similar forebody and hindbody girths, to dramatically reduced girths of the forebody relative to hindbody. The latter is associated
