The Anatomical Record, EarlyView.Abstract Fishes of the genus Enchodus were abundant and cosmopolitan in the Late Cretaceous, but are primarily known from isolated remains in Canada. Four well‐preserved fish skulls were recovered in recent years from ammolite mines sampling the Bearpaw Formation of Southern Alberta, and are here referred to Enchodus petrosus Cope, 1874.

Environmental influences on the abundance and sexual composition of white sharks Carcharodon carcharias in Gansbaai, South Africa. [PDF]
PLoS ONE, 2013 The seasonal occurrence of white sharks visiting Gansbaai, South Africa was investigated from 2007 to 2011 using sightings from white shark cage diving boats. Generalized linear models were used to investigate the number of great white sharks sighted per

How wildlife respond to tropical cyclones: short‐term tactics and long‐term impacts
Biological Reviews, EarlyView.ABSTRACT From butterflies to lizards and from sharks to seabirds, wildlife exhibit tactics to survive the impacts of tropical cyclones, also known as hurricanes, cyclones, or typhoons depending on where they occur. Some species seek refuge during the storm by moving, some remain in place and ride it out, and others move longer distances, avoiding the ...

Fish Scales: A Multifunctional Biomaterial from Nature
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Fish scales demonstrate nature's solution to impact protection through overlapping multilayered architecture. This biological design combines mineralized surfaces with collagen networks to achieve both flexibility and fracture resistance. The structural principles inspire advanced protective materials and biomedical implants, where damage tolerance ...

White sharks under threats in South Africa: a call for precautionary management action
Endangered Species ResearchSouth Africa was the first country to protect white sharks Carcharodon carcharias—an important decision taken despite limited data on population status, but guided by a precautionary approach in recognition of the species’ ecological and economic value ...

Ontogenetic and among-individual variation in foraging strategies of northeast Pacific white sharks based on stable isotope analysis. [PDF]
PLoS ONE, 2012 There is growing evidence for individuality in dietary preferences and foraging behaviors within populations of various species. This is especially important for apex predators, since they can potentially have wide dietary niches and a large impact on ...

Disappearance of white sharks leads to the novel emergence of an allopatric apex predator, the sevengill shark [PDF]
Scientific Reports, 2019 AbstractDespite global declines of apex predatory sharks, evidence for ecosystem consequences remains limited and debated. This is likely a result of both the logistical difficulties of measuring such processes in marine systems and also due to shifting baselines, whereby the ecosystem changes have occurred prior to monitoring.

Drivers of change in human–wildlife relationships: Southern Africa as an example
People and Nature, EarlyView.Abstract Human–wildlife relationships (HWRs) are changing globally in response to shifts in ecological dynamics and societal values, often resulting in contestation. With an increasing need to enable human–wildlife coexistence, it is essential to better understand the drivers of change in HWRs.

White Sharks Exploit the Sun during Predatory Approaches [PDF]
The American Naturalist, 2015 There is no conclusive evidence of any nonhuman animal using the sun as part of its predation strategy. Here, we show that the world's largest predatory fish-the white shark (Carcharodon carcharias)-exploits the sun when approaching baits by positioning the sun directly behind them.
