* Convention on International Trade in Endangered Species of Wild Flora and Fauna (CITES): This treaty restricts trade of certain species, including some dolphins, to ensure their survival.
* International Whaling Commission (IWC): While primarily focused on whales, the IWC also plays a role in dolphin conservation.
* International Maritime Organization (IMO): The IMO works to reduce the number of dolphin deaths caused by bycatch in fishing nets.
* United Nations Convention on the Law of the Sea (UNCLOS): This treaty sets out the legal framework for the conservation and management of marine life, including dolphins.
National:
* Marine Mammal Protection Act (MMPA): This US law prohibits the killing, harming, or taking of marine mammals, including dolphins, without a permit.
* Endangered Species Act (ESA): The ESA protects endangered and threatened species, including some dolphin species.
* Similar laws exist in many other countries, such as the European Union's Habitats Directive and the Australian Environment Protection and Biodiversity Conservation Act.
Organizations:
* World Wildlife Fund (WWF): The WWF works to protect dolphins and their habitats through conservation efforts.
* Ocean Conservancy: This organization advocates for policies that protect dolphins and other marine life.

It's important to note that the level of protection for dolphins varies depending on the species and the location. Some species are more vulnerable than others, and some countries have stronger protections than others.
Overall, dolphins are protected by a complex web of international and national laws and organizations. However, they still face many threats, including bycatch, habitat loss, and pollution.
