# Marine life

Marine life comes in a vast array of different forms, from the more or less familiar to the otherworldly and fascinating.
You can see marine life with activities like scuba diving, snorkeling, snuba, swimming, boating, or visiting an aquarium.

## Understand

According to salt content, the types of water are freshwater, brackish, and salt water.
Some marine species are unique to a region or a climate zone. But as the oceans are connected, many of them have cosmopolitan distribution, meaning they can be found all around the world.

## Species
### Manatees

    Main article: Natural springs in Florida
These large aquatic creatures live in tropical waters in several places worldwide.
One prime location to see manatees is in Florida, in places like 28.5175-82.57251 Weeki Wachee Springs , where the water is very clear and you can go kayaking with manatees. 28.9481-81.342 Blue Spring State Park is another location known for its manatees. The 21st century has seen a decline in Florida's manatee population due to habitat loss, global warming, and recreational activities (boats, jetskis).
The marshes and mangrove swamps of Mexico's Yucatan Peninsula are home to many manatee populations. Manatee watching tours are available in popular resort areas like Tulum and Playa del Carmen, particularly in the 19.383333-87.7916673 Sian Ka'an Biosphere Reserve. The town of 17.723-92.01294 Catazajá in Chiapas has a large lagoon that is famous for its manatees.
The closely related dugong lives in the waters of Southeast Asia, East Africa, and Australia.

### Sharks

Large sharks such as great whites and hammerheads can be found in oceans worldwide, except in the polar regions. However, they are low in numbers. They tend to concentrate in certain coastal regions where prey is easy to find.
"Shark dives" are popular in shark concentration spots worldwide. If the sharks are dangerous like great whites, you'll see them from inside a metal cage ("cage diving") to stay safe. For most other species, no cage is needed.

* New England. Off the coast of New England, near New York City and Boston, species like the mako and blue sharks can be seen. Despite the northern latitude, waters are relatively warm here due to the Gulf Stream. Tours depart from Montauk, Cape Cod, and other locations. (updated Jun 2017)

* 37.7389-123.066712 Farallon Islands. Off the coast of San Francisco. Great white sharks often visit here, and "cage diving" is possible. However, many visitors report not seeing any sharks, due to low underwater visibility, and because the operators are not allowed to "chum" (use bloody fish as shark bait). (updated Jun 2017)
* The -22.739113.62813 Ningaloo Coast near Exmouth and Coral Bay in Western Australia is a world heritage site and various sharks can be seen here. As it's a subtropical area, the waters are fairly warm
* The -19.42101154.97178714 Coral Sea Marine Park just to the east of the GBR has plenty. Unfortunately, getting here is a little difficult
Generally, large sharks do not do well in captivity. It appears that no great white sharks or hammerhead sharks can be viewed in captivity. However, smaller sharks can be seen in some aquariums, as well as the whale shark.
