Neogene Caribbean elasmobranchs: diversity, paleoecology and paleoenvironmental significance of the Cocinetas Basin assemblage (Guajira Peninsula, Colombia) [PDF]

Biogeosciences, 2019
The Cocinetas Basin is located on the eastern flank of the Guajira Peninsula, northern Colombia (southern Caribbean). During the late Oligocene through the Pliocene, much of the basin was submerged.

Shedding light on the parasite communities and diet of the deep‐sea shark Deania profundorum (Smith & Radcliffe, 1912) (Squaliform: Centrophoridae) from the Avilés Canyon (southern Bay of Biscay)

Journal of Fish Biology, EarlyView.
Abstract Deep‐sea elasmobranchs are less resilient to the increasing scale of anthropogenic impacts such as fisheries, owing to their life‐history traits. The necessity for proper management measures is hampered by the scant knowledge on these taxa and their biology. Here we provide the first comprehensive insight into the parasite infracommunities and

Insights into the structure of grey reef shark aggregation, Carcharhinus amblyrhynchos (Bleeker, 1856), in two distinct channels of the Maldivian archipelago, Indian Ocean

Journal of Fish Biology, EarlyView.
Abstract The grey reef shark Carcharhinus amblyrhynchos is one of the most frequently encountered reef‐associated shark species in the Maldives, yet very little is known about its local size structure or population dynamics. This study provides new insights into two aggregations of C.

Unravelling the skin of the nurse shark: A morphological description of the placoid scales of Ginglymostoma cirratum

Journal of Fish Biology, EarlyView.
Abstract Ginglymostoma cirratum, commonly known as the nurse shark, is a nocturnally active benthic shark, often found in western and eastern Atlantic waters. Although this shark has been well explored in many biological aspects, few studies have thoroughly examined the morphology of its dermal denticles (or placoid scales).

The role of two anatomically separate olfactory bulbs in shark food odor tracking [PDF]

, 2017
Most sharks have well-developed olfactory systems and depend to a large degree on odor information to locate food, home and navigate, and possibly detect predators and mates.

Dental Morphology, Palaeoecology and Palaeobiogeographic Significance of a New Species of Requiem Shark (Genus Carcharhinus) from the Lower Miocene of Peru (East Pisco Basin, Chilcatay Formation)

Journal of Marine Science and Engineering, 2022
Nowadays, the requiem sharks comprise one of the most diverse and widespread families of selachians, i.e., Carcharhinidae. Among the carcharhinids, the genus Carcharhinus has the largest number of living species, namely, at least 35.
