![]() "It's a long list of potential species that can be restored, and ReShark is the opportunity to reintroduce these populations. "It doesn't stop with zebra sharks," Hayes said. Yet reintroducing aquatic animals back to ocean environments is much harder because it's simply never been done. Zebra sharks are popular attractions for eco-tourism and public aquariums. Due to the black and white stripes of the pups eventually turning to spotted adults, the two different life stages were thought to be differing species. Scientists have successfully "rewilded" several land animal populations, from pandas to wolves to condors and black-footed ferrets, according to NatGeo. Stegostoma fasciatum This mollusk crunching coastal carpetshark was misidentified for years by taxonomists. ![]() ReShark aims to release 500 zebra sharks over the next 10 years. Scientists are hopeful these zebra sharks will soon repopulate. They live in a "shark daycare" of sorts until biologists certify that juveniles are ready for tagging and releasing in marine-protected areas. These eggs are then transported by air to local hatcheries in Indonesia, where they're cared for by so-called "shark nannies." This global effort is led by ReShark, "an international collective of over 60 conservation organizations, aquariums, government agencies and more, dedicated to threatened sharks and rays around the world."įirst, eggs encased in shell-like cocoons - called mermaid's purses - are bred in scientifically managed populations in aquariums around the world. and in some cases, the only place where we have the genetics and the species left are often aquariums," Hayes said. Browse Getty Images premium collection of high-quality, authentic Shark Egg stock photos, royalty-free images, and pictures. "We have species disappearing off the face of this planet at a rapid rate. Earth's ocean ecosystems need these apex predators in order to thrive. National Geographic photographers Jennifer Hayes and her husband David Doubilet documented this process of "rewilding" from the waters of Raja Ampat, an archipelago in the West Papua province of Indonesia, where these slow-moving sharks have nearly disappeared due to fishing. In an unprecedented effort, 15 aquariums from around the world are teaming up to raise endangered baby zebra sharks and reintroduce them into the wild, where populations have nearly gone extinct. They are kept in aquaria.National Geographic has an inside look at programs helping the threatened species, including a program that reintroduces baby sharks back into the ocean. They are taken in many fisheries and their coral reef habitat is threatened. Vulnerable on the International Union for Conservation of Nature (IUCN) Red List. Tend to be sluggish by day and more active at night. Often seen resting, propped up on their pectoral fins, mouth open, facing the current. ![]() Lays large dark brown to purple-black egg cases anchored to the bottom with tufts of fibers. Prey – Mollusks, crustaceans and small bony fishes. Indo-west Pacific tropical and continental and insular shelves, eastern Africa to Japan, New Caledonia and Palau. ![]() Adults and juveniles rest in coral reef lagoons and channels, but the striped young are rarely seen and may be in deeper water (>50 m). Most of these sharks average slightly more than 8 ft, and maximum size is thought to be just over 11 ft. Males mature between 4.7 to 6 ft, while females mature around 5.5 to 5.75 ft. The shark is approximately 8 to 14 inches when hatched. The zebra female lays fertilized eggs in tough capsules covered with tufts of filaments, which attach the eggs to the seafloor. These saddles break up into spots in sharks 20 to 35 inches in length, and are more uniformly distributed on large sharks. The young are yellowish below, dark brown above with vertical yellow stripes and spots separating dark saddles. Its body has very distinct ridges and spots. A large, slender shark with a large broad tail as long as its body.
