Revista Latinoamericana de HerpetologíaWe report the first record for the diet of the Cauca Coralsnake Micrurus multiscutatus, preying on a caecilian of the genus Caecilia in the pacific lowlands of Colombia. In addition, we describe a new hunting maneuver used by the coralsnake to subdue the

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-

Don't You Know That I'm Toxic? Wild Birds Learn to Avoid a Novel Aposematic Warning Signal
Ecology and Evolution, Volume 15, Issue 12, December 2025.The foraging behaviours of predators towards aposematic prey have been studied extensively and there is much empirical evidence to support this theory. Often, studies involving wild species are relatively short‐term and so there is a possibility that any aversive behaviours exhibited by predators are merely neophobic. In this study, we ensure predators

Population dynamics of the sea snake Emydocephalus annulatus (Elapidae, Hydrophiinae)
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 ...

Journal of Morphology, Volume 286, Issue 11, November 2025.Snake head shape is weakly constrained by phylogeny but strongly influenced by ecology. Significant convergence was detected in fossorial and aquatic snakes, while diet mainly drove morphological variation without convergence. ABSTRACT Morphological convergence—where distantly related species evolve similar traits in response to shared ecological ...

Oral microbiota of Brazilian captive snakes
Journal of Venomous Animals and Toxins including Tropical Diseases, 2009 The present work aimed to determine the oral microbiotic composition of snakes from São José do Rio Preto city, São Paulo State, Brazil. Ten snake species, comprising the families Boidae, Colubridae, Elapidae and Viperidae, were submitted to ...

Revista Latinoamericana de Herpetología, 2021 Las cecilias y las serpientes de coral son sin duda unos de los vertebrados más fascinantes. Ambos comparten algunas similitudes evolutivas (convergencias) como respuesta a la necesidad de adaptarse a la vida subterránea, donde la vista es relegada a un ...

Ecological Research, Volume 40, Issue 6, November 2025.We developed the CUSCO pipeline. It enables rapid construction of a phylogenetic tree using whole genome sequences and identifies useful marker genes for additional samples. It can handle polyploid genomes. ABSTRACT Single‐copy orthologs are often used to reconstruct phylogenetic trees of life. A set of single‐copy orthologs can be prepared by building

Journal of Comparative Neurology, Volume 533, Issue 10, October 2025.In snakes, profound differences in retinal architecture are observed between diurnal and nocturnal species. Additionally, in the rod‐dominated retinas of nocturnal snakes, coexpression of the cone opsins SWS1 and LWS in individual cones is common, while rhodopsin (RH1) is restricted to typical rods.

INVENTARISASI JENIS – JENIS ULAR YANG DITEMUKAN DI SEKITAR PANTAI MERTA SARI DAN PADANG GALAK
Simbiosis: Journal of Biological Sciences, 2017 Sea snakes have a strong venom and when they bite can be fatal for humans, whereas snakes found in mangrove areas are weak venomous snakes and non-venomous snakes (McKay, 2006).
