Mistaken identity may explain why male sea snakes (Aipysurus laevis, Elapidae, Hydrophiinae) "attack" scuba divers. [PDF]
Sci Rep, 2021 Scuba-divers on tropical coral-reefs often report unprovoked “attacks” by highly venomous Olive sea snakes (Aipysurus laevis). Snakes swim directly towards divers, sometimes wrapping coils around the diver’s limbs and biting.

Sexual dimorphism in aipysurine sea snakes (Elapidae, Hydrophiinae). [PDF]
R Soc Open Sci, 2023 The transition from terrestrial to aquatic life by hydrophiine elapid snakes modified targets of natural selection and likely affected sexual selection also. Thus, the shift to marine life also might have affected sexual dimorphism.

Horizontal Transposon Transfer and Its Implications for the Ancestral Ecology of Hydrophiine Snakes. [PDF]
Genes (Basel), 2022 Transposable elements (TEs), also known as jumping genes, are sequences able to move or copy themselves within a genome. As TEs move throughout genomes they often act as a source of genetic novelty, hence understanding TE evolution within lineages may ...

Sexual dimorphism and skull size and shape in the highly specialized snake species, Aipysurus eydouxii (Elapidae: Hydrophiinae). [PDF]
PeerJ, 2021 Background Snakes exhibit sexual dimorphism in both head size and shape. Such differences are often attributed to different reproductive roles and feeding habits. We aim to investigate how sexual dimorphism is displayed in the highly specialised fish-egg-

Using a null hypothesis framework to test expectations of disparity in an adaptive radiation. [PDF]
R Soc Open SciAdaptive radiations are expected to generate striking differences in species and morphological diversity between closely related groups. Not all hypotheses in evolutionary biology, including these observed disparities, are amenable to experimental ...

Population dynamics of the sea snake Emydocephalus annulatus (Elapidae, Hydrophiinae). [PDF]
Sci Rep, 2021 For sea snakes as for many types of animals, long-term studies on population biology are rare and hence, we do not understand the degree to which annual variation in population sizes is driven by density-dependent regulation versus by stochastic abiotic ...

The Unusual Metalloprotease-Rich Venom Proteome of the Australian Elapid Snake Hoplocephalus stephensii. [PDF]
Toxins (Basel), 2022 The Australasian region is home to the most diverse elapid snake radiation on the planet (Hydrophiinae). Many of these snakes have evolved into unique ecomorphs compared to elapids on other continents; however, their venom compositions are poorly known ...

The adaptive significance of large size at birth in marine snakes. [PDF]
R Soc Open Sci, 2023 Evolutionary shifts from one habitat type to another can clarify selective forces that affect life-history attributes. Four lineages of snakes (acrochordids and three clades within the Elapidae) have invaded marine habitats, and all have larger offspring
