Whale shark on a white shark’s menu

Marine Biodiversity, 2015
As the world’s largest fish, whale sharks Rhincodon typus could be assumed to be predator-free. Juvenile whale sharks are known to be preyed upon by sharks, marlin and orcas, and, although unconfirmed, bite marks on a sub-adult whale shark were attributed to white sharks Carcharodon carcharias (Department of the Environment and Heritage, DEH 2005 ...

Expanded niche for white sharks

Nature, 2002
Until the advent of electronic tagging technology, the inherent difficulty of studying swift and powerful marine animals made ecological information about sharks of the family Lamnidae difficult to obtain. Here we report the tracking of movements of white sharks by using pop-up satellite archival tags, which reveal that their migratory movements, depth

Mode of uterine milk secretion in the white shark

The Anatomical Record, 2022
AbstractExamination of the uterus of a dead female white shark (Carcharodon carcharias), which contained the earliest known white shark embryos, revealed that the uterine wall produces lipid‐rich secretion (histotroph or “uterine milk”) for embryonic nutrition.

Dental ontogeny of a white shark embryo

Journal of Morphology, 2016
ABSTRACTUnlike most viviparous vertebrates, lamniform sharks develop functional teeth during early gestation. This feature is considered to be related to their unique reproductive mode where the embryo grows to a large size via feeding on nutritive eggs in utero. However, the developmental process of embryonic teeth is largely uninvestigated.

On Security of a White-Box Implementation of SHARK

2015
In a white-box attack context, an attacker has full visibility of the implementation of a cipher and full control over its execution environment. As a countermeasure against the threat of a key exposure in this context, a white-box implementation of the block cipher SHARK, i.e., the white-box SHARK, was proposed in a piece of prior work in 2013 ...

Mechanics of biting in great white and sandtiger sharks

Journal of Biomechanics, 2011
Although a strong correlation between jaw mechanics and prey selection has been demonstrated in bony fishes (Osteichthyes), how jaw mechanics influence feeding performance in cartilaginous fishes (Chondrichthyes) remains unknown. Hence, tooth shape has been regarded as a primary predictor of feeding behavior in sharks.

Effect of fear and representations of great white sharks on great white shark conservation behavior

Great white sharks are listed as a vulnerable species under the International Union for Conservation of Nature (IUCN) red list. This study uses the theory of planned behavior (TPB) to test how different factors such as attitudes, subjective norms, perceived behavioral control along with representations and fear of great white sharks affect great white ...
