Dolphins can be drowned by becoming entangled in fishing nets.
They are mammals and have to rise to the surface regularly to breath air.
the biggest threat dolphins are tuna nets that dolphins are gettting caught in fishing nets when catching fish such as tuna
sharks and we hurt them because they get trapped in tuna nets;[ also pollution
One thing that we can do to help all the dolphins, is to stop pollution to the ocean. If a plastic water bottle is in the water, a dolphin could mistaken it for a fish. We could also use nets (to catch fish) safe for dolphins, by having little gates at different parts of the nets, and 3-4 divers could be there to make sure no dolphins get caught, and if any do, to help them through the gates.

Dolphins are mammals, they Breathe air. If trapped underwater they eventually suffocate or drown.
Dolphins are endangered. They are caught by fishermen and used in tuna. They also get stuck in nets and suffocate.
Many dolphins are killed in the process of tuna catching. Yellow Fin Tuna follow dolphins and the companies that catch tuna watch for the dolphins because they know that tuna is in the area. They spread miles of huge nets out to catch the tuna in, but they also get dolphins in the net. Because the dolphins are mammals they often drown in the nets, some jump over the nets, and others are pulled into the tuna boats. The tuna companies also set off bombs in the water that confuse the dolphins and this drives them into the nets as well. Today, companies state that they are "dolphin free" on their cans, but the dolphin still die.
