Glow-in-the-Dark Sharks

February 22, 2011 Many deep-water marine creatures sport some sort of luminescent or light-emitting organ.  These structures function to distract predators, or serve as lures to draw prey.  The lure of the anglerfish, for example, can be retracted towards the mouth, bringing prey in close … Read more about Glow-in-the-Dark Sharks

Whales Eat Sharks

January 31, 2011 Killer whales (Orcinus orca) are common off the northwestern coast of the US and Canada.  Decades ago researchers learned that there were two separate populations of these animals - “resident” whales who remain in the area for long periods of time, and “transient” whales who … Read more about Whales Eat Sharks

Bigmouth Strikes Again

Different animals eat different diets, in part because they have different types of teeth. The piercing and tearing teeth of a carnivore, for example, in comparison to the flat chewing teeth of a plant-eater. Think tigers versus cows, for terrestrial animals. Among sharks, contrast the thousands of … Read more about Bigmouth Strikes Again

Shark Cartilage Trials

December 16, 2010 People suffering from terminal diseases often grasp at unproven therapies.  For several decades one of these has been shark cartilage, claimed by some to be a cure for cancer.  This idea came originally from the mistaken belief that sharks themselves do not get … Read more about Shark Cartilage Trials

Whale Sharks are BIG Eaters!

December 4, 2010 Whale sharks are one of the three living species of filter-feeding shark, along with the basking shark and the megamouth shark.  Despite their size - whale sharks can reach 40 feet in length - they subsist on some of the smallest organisms in the sea.  These animals must … Read more about Whale Sharks are BIG Eaters!

Parthenogenesis in sharks

Parthenogenesis, from the Greek meaning “virgin birth” is an odd quirk of embryonic development that allows female animals of some species to give rise to offspring without a male genetic contribution - usually by a doubling of the egg genome to generate a new embryo with the proper number of … Read more about Parthenogenesis in sharks

Dr. Jennifer Schmidt received her PhD from Northwestern University in Chicago, and did postdoctoral work at Princeton University. She is a geneticist and molecular biologist by training, with a long-standing interest in conservation genetics, and in the use of genetic tools to characterize wild populations. In 2001 she partnered with the Shark Research Institute to use genetics to understand the migration and reproduction of whale sharks. Her global whale shark genetic study includes animals from nearly 20 different countries, and has taken her to field sites in places like Mexico, Djibouti and the Philippines. In 2005 she became Director of Genetic Studies for the Shark Research Institute, and since 2016 has served as SRI Director of Science & Research.
