White Shark vs Orca – Who’s the Top Predator

When orcas and white sharks cross paths, only one can prevail as the true apex predator. New research from the Monterey Bay Aquarium published in Nature Scientific Reports details these rare, sometimes brutal encounters—and their ecological implications.It’s a study decades in the making because observations of the two creatures interacting is a rarity. • Read the Aquarium's blog: https://mbayaq.co/2KSkiMq • Read the paper: https://mbayaq.co/2Zm2uwH • _ • Sharks may well be the most fascinating and misunderstood animals in the ocean. Their ancestors swam the seas when dinosaurs roamed the shores, and sharks have survived eons of change on Earth. Today, their future is uncertain. • Despite their powerful presence in the human imagination, sharks remain creatures of mystery. We know little about their lives, including where and how they live, and where their young are born. They're identified internationally as vulnerable to extinction, and protected in many parts of the world. • Since 2002, we and our research colleagues at Stanford University, California State University, Long Beach, and other institutions have worked to expand our understanding of white sharks. We're making significant contributions to knowledge about where white sharks in the eastern Pacific Ocean travel, where they live and about their basic physiology. The new data are generated from electronic tracking tags, photo identification and genetic analyses using tissue and blood samples collected from adult and juvenile sharks. • We're combining field tagging with laboratory studies—and working to advance policies that will identify and protect critical habitat for sharks and other species. We also promote policies in the U.S. and internationally to end practices that threaten all shark species: the targeting of sharks for their lucrative fins, and the use of indiscriminate fishing practices that catch and kill sharks in gear intended for other species. • The Aquarium is promoting innovative study, awareness and conservation of white sharks. Through our work we can promote public understanding and protection of this ecologically important and threatened species. • Our research involves: • Juvenile White Shark Research: Juvenile young of the year white sharks are found each summer in the Southern California Bight and as bycatch in the fisheries of Mexico and California. Yet we don't know where they're born, who the parents are, where breeding occurs or how they join adult populations. We're studying their movement, habitats, diet, population size and how they're affected by environmental toxins. • Adult White Shark Research: We're learning how to protect adult white sharks from overfishing and the effects of bycatch by studying their movement, population size and foraging patterns. • White Shark Genetics: To conserve white sharks, we need to know more about the movement between our coastal white sharks and those of Mexico, Australia, New Zealand and South Africa. Genetic (DNA) studies provide clues about population structure, parentage and the origins of white shark products found in global fish markets. • Donate to help out white shark research: http://mbayaq.co/1LBB9fQ
