Interactions of Mucus Monosaccharides and the Epidermal Microbiome in Four Benthic Elasmobranchs. [PDF]
Environ Microbiol RepHere we collected mucus and microbes from the skin of Elasmobranchs to identify interactions between mucus and the microbial community. We identified key microbial genes involved in the metabolism of mucus carbohydrates in Elasmobranchs. ABSTRACT Epidermal mucus is a complicated mixture of macromolecules which acts as the first line of defence for ...

Sexual Size Dimorphism in Rays and Skates (Elasmobranchii: Batoidea). [PDF]
Ecol EvolABSTRACTSexual size dimorphism (SSD) is a widely observed but poorly understood phenomenon in which male and female animals differ in body size (e.g., length or mass). Despite extensive research on the interspecific distribution of SSD across various lineages, the evolutionary drivers behind male‐biased and female‐biased SSD remain contentious.

A new chondrichthyan fauna from the Late Jurassic of the Swiss Jura (Kimmeridgian) dominated by hybodonts, chimaeroids and guitarfishes [PDF]
, 2017 The fossil record of chondrichthyans (sharks, rays and chimaeroids) principally consists of isolated teeth, spines and dermal denticles, their cartilaginous skeleton being rarely preserved.

Bransonelliformes – a new order of the Xenacanthimorpha (Chondrichthyes, Elasmobranchii) [PDF]
Fossil Record – Mitteilungen aus dem Museum für Naturkunde, 2007 The order Bransonelliformes is erected for the genera <i>Bransonella</i> Harlton, 1933 and <i>Barbclabornia</i> Johnson, 2003 based on the distinct characters of an inverted "V"-nested pattern of ornamentation preliminary on the labial aspect at the tooth cusps, the presence of labial foramina, and the occasional occurrence of a
