Shark skin denticles (scales) are diverse in morphology both among species and across the
body of single individuals, although the function of this diversity is poorly understood. The …

Sibert and Rubin (Reports, 4 June 2021, p. 1105) claim to have identified a previously
unidentified, major extinction event of open-ocean sharks in the early Miocene. We argue …

Sensory systems allow organisms to sense and respond to stimuli in their environments. As
with most animals, elasmobranchs rely on all of their senses, often in concert, to mediate …

Elasmobranchs are covered in scale‐like structures called dermal denticles, comprising
dentine and enameloid. These structures vary across the body of an individual and between …

Dermal denticles cover the skin of sharks for protection and may have additional functions,
depending on the environment. The aim of the present study was to analyze the …

The aim of this study was to reveal potential relationship between the main flow field around
a shortfin mako shark and the surface morphology of shark skin. Firstly, a numerical …

The taxonomic status and identification of the deep-sea sharks of the genus Deania have
been controversial mainly due to morphological similarities between some of its species …

Oral denticles of sharks are composed by a crown, dentine covered by a layer of enameloid
and pulp cavity, the same structure of the dermal denticles found across the body surface of …

Shark skin is covered by small structures called dermal denticles whose functions are
diverse, such as protection, bioluminescence, hydrodynamics, among other functions. These …

Shark skin is predominantly specialized for swimming and protection, with the dermal
denticle being the main structure associated with these abilities. The dermal denticle is a …
