Essay / Local Shark Movements - 2340
The ability to move is one of the defining characteristics of animals. This motor skill act can be accomplished in a variety of ways, such as swimming, flying, or walking, and for a variety of purposes. These goals include foraging, mating, finding suitable habitat, or evading predators. More precisely, the types of movements can be classified into two broad categories: local movements and migrations. The great white shark, Carcharodon carcharias, is a species of shark that exhibits both of these movement behaviors and often results in shark-human interaction. The objectives and environmental implications of local movements and migration patterns of white sharks are being researched and understood. Local movements are defined as the movement of an organism from one place to another, usually over a short distance and for short periods of time. For some animals, this involves predation or herbivory, mating, or foraging for resources. The local movements of white sharks have been studied by many people, and their research findings have detailed the purposes of their movements. One of the goals of their movements is sexual segregation. A study which showed this was carried out by Kock, O'Rain, Mauff, Meyer, Kotze and Griffiths at False Bay, located at the southwestern tip of South Africa, where it opens into the Atlantic Ocean. There is an island in this bay that is home to the second largest island breeding colony of Cape fur seals. All these conditions make it an excellent gathering place for white sharks. Researchers lured the sharks to the boat using a dense foam seal lure to mark 56 sharks and determine their sex (39 females, 17 males). The sharks were monitored middle of paper overtime. Some of these long-term effects have been observed in other wildlife attracted for the viewing pleasure of humans and include "provisioning dependence, overeating, malnutrition, increased aggression, altered behavior, ecological relationships disrupted and an imbalance in energy budgets” (Huveeneers et al. 2013). Sharks reside in almost all ocean waters around the world, and the great white shark in particular inhabits a wide range of areas. Although many studies have been carried out on this species, local movements, migratory patterns and their purposes are not yet fully known. More investigation and research needs to be done in order to implement coordinated global conservation of these top predators, as increasing interaction between sharks and humans begins to negatively impact populations..
