Sexual dimorphism in aipysurine sea snakes (Elapidae, Hydrophiinae) [PDF]
Royal Society Open Science, 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.

Mistaken identity may explain why male sea snakes (Aipysurus laevis, Elapidae, Hydrophiinae) “attack” scuba divers [PDF]
Scientific Reports, 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.

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

Population dynamics of the sea snake Emydocephalus annulatus (Elapidae, Hydrophiinae) [PDF]
Scientific Reports, 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 ...

Characterization and phylogenetic analysis of the complete mitochondrial genome of Aipysurus eydouxii Gray 1849 (Elapidae: Hydrophiinae) [PDF]
Mitochondrial DNA. Part B. ResourcesHydrophiine sea snakes represent ecologically significant and species-rich marine predatory reptiles, many of which inhabit marine environments throughout their entire lifecycles.

Divergence in life-history traits among three adjoining populations of the sea snake Emydocephalus annulatus (Hydrophiinae, Elapidae) [PDF]
Scientific Reports, 2022 Life-history traits such as rates of growth, survival and reproduction can vary though time within a single population, or through space among populations, due to abiotically-driven changes in resource availability.

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-

Sexual dimorphism in size and shape of the head in the sea snake Emydocephalus annulatus (Hydrophiinae, Elapidae) [PDF]
Scientific Reports, 2021 In snakes, divergence in head size between the sexes has been interpreted as an adaptation to intersexual niche divergence. By overcoming gape-limitation, a larger head enables snakes of one sex to ingest larger prey items.

Using a null hypothesis framework to test expectations of disparity in an adaptive radiation [PDF]
Royal Society Open ScienceAdaptive 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 ...
