Both U.S. and Soviet militaries have trained dolphins. They can be used for rescuing lost naval swimmers and locating underwater mines.
100 Mind-Blowing Dolphins Facts
The closest living relatives of hippopotamuses are whales, dolphins, and porpoises.
Bottlenose dolphins are the only other species to have names for themselves.
Sloths can hold their breath longer than dolphins can. By slowing their heart rates, sloths can hold their breath for up to 40 minutes. Dolphins need to come up for air after about ten minutes.
Dolphins have names for one another. According to National Geographic, dolphins use a unique whistle to distinguish between different members of their pods.
Cows have “best friends” and will get stressed when separated. If a cow is taken away from her “best friend,” her stress levels will decrease her milk yields. Surprisingly, cows are not the only species that form attachments to certain companions. The “best friend” preference is also observed in certain bats, elephants, chimps, and dolphins.
Dolphins have names. Research has found that dolphins use their unique vocal whistles to identify and differentiate one another. When a specific call was played back to the dolphins, they would respond differently each time.
Sloths hold their breaths longer than dolphins. On the rare occasions that sloths leave their trees to go for a swim, they hold their breath underwater for up to 40 minutes. This is 30 minutes longer than the average dolphin’s record.
A rare pink dolphin resides in Louisiana. This rare dolphin was first discovered in 2007. Its pink colour is said to come from a rare genetic mutation and no other pink dolphins have been discovered since.
Sloths can hold their breath longer than dolphins. Sloths can slow their heart rates. When they do, sloths can hold their breath for up to 40 minutes. On the other hand, dolphins need to come up to the surface to breathe after 10 minutes.
Trained dolphins protect nuclear weapons. One of the world’s biggest stockpiles of nuclear weapons (a U.S. Navy base near Seattle) is defended by trained dolphins.
Sloths can hold their breath longer than dolphins. Dolphins need to come up for air every 10 minutes, but by slowing their heart rate, sloths can hold their breath for 40 minutes!
Dolphins give each other names. A unique whistle is used to distinguish members in their pod.
Sloths can hold their breath longer than dolphins.
Every 10 minutes dolphins need to come up for air, but sloths can hold their breath for 40 minutes.
Dolphins name each other. Dolphins use unique whistles to distinguish each other in a pod.
Wild dolphins call each other by name. They let out a unique whistle to identify each other and will respond if they hear their call played back.
Dolphins have been seen wrapping sea sponges around their long snouts to protect them from cuts while forageing for food.
Sharks do not hunt humans or consider humans food. Shark incidents occur when sharks are hunting for seals, dolphins, or other “human-sized” prey. It’s a case of mistaken identity!

Dolphins only shut half their brain off when sleeping. The other half stays at a low level of alertness to protect against predators, obstacles, or other animals.
Dolphins are highly trainable creatures. During the Vietnam War, both America and the Soviet Union trained dolphins. These animals could detect mines, deliver needed equipment to divers, retrieve lost items, and protect submarines. Dolphins are very intelligent and emotional. The dolphin who portrayed Flipper chose not to return to the surface for air and died with her trainer, essentially committing suicide.
KILLER WHALES ARE DOLPHINS. Orcas, also known as “killer whales”, are the largest members of the dolphin family. They are one of the ocean’s top predators, preying on a diverse range of marine species, which include many fish species, penguins, seabirds, sea turtles, cephalopods and marine mammals such as seals and even whales larger than themselves.
Hippos’ closest living relatives are the aquatic mammals: whales, dolphins and porpoises.
When humans take a breath, they replace only 15% of the air in their lungs with fresh air. When dolphins take a breath, they replace 90% of the air in their lungs with fresh air.
Orcas are dolphins, not whales.
