Shearing Tooth Morphology May Allow Sharks to Access Higher Trophic Levels at Smaller Sizes
Ecology and Evolution, Volume 15, Issue 8, August 2025.Predator morphology imposes limitations on prey selection due to biomechanical constraints, making some prey functionally inaccessible and thereby constraining predator trophic niches. We assessed how two key components of trophic morphology—tooth shape and body size—affect prey selectivity and trophic niche in two sympatric sharks with contrasting ...

Slippery and Smooth Shark Skin: How Mucus Transforms Surface Texture
Journal of Morphology, Volume 286, Issue 4, April 2025.Shark surfaces consist of denticles and a mucus layer, yet mucus is an understudied aspect of shark surfaces. Using gel‐based surface profilometry to visualize and quantify surface texture changes, we found that mucus covered denticles on the dorsal fin tip and tip of the tail's trailing edge.

reproductive biology and seasonal distribution of mustelus schmitti (elasmobranchii: triakidae) in the rio de la plata oceanic front, south-western atlantic [PDF]
Journal of the Marine Biological Association of the United Kingdom, 2005 the population structure and reproductive biology of mustelus schmitti was analysed during autumn (1994, 1995) and spring (1994) in the rio de la plata oceanic front. the samples consisted mainly of adult males and immature females, indicating that nursery areas are situated elsewhere.

, 2019 The environment of the Bahía Blanca estuary is considered a hot spot in terms of pollution. Bioindicators should have the ability to react relatively fast to certain pollutants and environmental disturbances. Therefore, an exploratory study was carried out determining and quantifying the concentrations of cadmium (Cd), chromium (Cr), copper (Cu), lead (
