Quick Facts About Sharks

Sharks are critical apex predators contributing to a balanced marine ecosystem. Seagrass beds provide important habitat for many fish and invertebrate species as they mature, before moving onto coral reefs and other ecosystems. Coral reefs, kelp forests, and seagrass beds are reliant on sharks’ existence in the food chain to keep these beautiful and important habitats stable.
The National Wildlife Federation (NWF) is committed to wildlife conservation and education, and as part of our work, we spotlight vulnerable wildlife species needing extra support to ensure their populations thrive in an ever-changing world. The International Union for the Conservation of Nature (IUCN) Red List, which has identified that more than 47,000 wildlife species worldwide are threatened with extinction, including 37 percent of sharks and rays.
An endangered species is a plant or animal facing extinction if its population numbers do not increase. In the U.S., individual states and the federal government can list a species as threatened, endangered, or a number of other designations. The U.S. Endangered Species Act (ESA) protections are enforced at the federal level by the U.S. Fish and Wildlife Service (USFWS) and the National Marine Fisheries Service (NMFS) for certain marine species. The IUCN Red List provides conservation status assessments for species globally used by governments internationally to determine protections.

The National Aquarium in Baltimore
If you are in the neighborhood, visit The National Aquarium in Baltimore, Maryland.
The National Aquarium, NWF’s Maryland affiliate partner, connects people with nature to inspire compassion and care for our ocean planet. They house 10 shark species including the sand tiger and sandbar sharks.
One of their most popular exhibits is Shark Alley, however only six of the 10 shark species can easily be found, which makes the other four a fun challenge!
The Aquarium also has their Blacktip Reef exhibit that hosts daily educational opportunities for visitors to learn more about sharks including the behind-the-scenes shark tours, and “shark talks.”
