Twins! Microsatellite analysis of two embryos within one egg case in oviparous elasmobranchs.
PLoS ONE, 2019 Elasmobranchs display various reproductive modes, which have been key to their evolutionary success. In recent decades there has been a rise in the number of reported cases of foetal abnormalities including fertilised, double-embryos held within one egg ...

Distinct Responses of Elasmobranchs and Ray-Finned Fishes to Long-Term Global Change
Frontiers in Ecology and Evolution, 2020 Both biotic and abiotic factors likely played a role in influencing the diversification patterns of clades. Although the role of environmental forcing on the long-term evolution of biodiversity has been explored for invertebrate clades, little is known ...

Osmoregulation in Elasmobranchs [PDF]
American Zoologist, 1977 Osmoregulatory mechanisms were examined in major groups of fishes including hagfish, holocephalans, elasmobranchs, the coelacanth, and ray-fin fishes. Four main patterns of body fluid composition emerged. These represent the three main osmoregulatory processes in the marine environment and the one in fresh water.

Elasmobranch bycatch in the Italian Adriatic pelagic trawl fishery.
PLoS ONE, 2018 Elasmobranchs are among the most threatened long-lived marine species worldwide, and incidental capture is a major source of mortality. The northern central Adriatic Sea, though one of the most overfished basins of the Mediterranean Sea, supports a very ...

First reports of Megamouth Shark, Megachasma pelagios Taylor, Compagno & Struhsaker, 1983 (Lamniformes, Megachasmidae), in Peru [PDF]
Check List, 2020 Megamouth Shark, Megachasma pelagios Taylor, Compagno & Struhsaker, 1983, is one of the least-known shark species worldwide. We report the encounters of four megamouth sharks: one caught in a driftnet off Piura (November 2016; sex indeterminate),

The impact of the Pull of the Recent on extant elasmobranchs
Palaeontology, 2020 Modern elasmobranchs have a long evolutionary history and an abundant fossil record that consists mainly of teeth. Many fossil taxa have living representatives. However, the representation of extant taxa in the fossil record is unknown.
