  (#6) Dolphins Torture Their Food Before Eating It

  While the reason can vary, dolphins love to play with their food before they eat it. This idea is cute until you remember that dolphins eat living creatures. So, you might see dolphins throwing fish, squid, and other sea creatures into the air before eating them. 

  The motives of this behavior depend on the situation. In many cases, dolphins torture their food as a safety precaution. Some of their prey, such as octopuses, have defense mechanisms. So, by tossing and ripping their food, it's easier for dolphins to safely consume their meals. Yet, in some instances, dolphins just like to play or show off to other dolphins.

  "A lot of smaller fish that dolphins catch are swallowed quickly underwater," said Whale and Dolphin Conservation field officer Charlie Phillips. "It's only the bigger prey that we tend to see getting this sort of treatment."

  (#7) Dolphins Use Toxic Pufferfish To Get 'High'

  If you thought humans were the only creatures to abuse dangerous substances, think again. Animals like horses, elephants, and monkeys have all been reported to be drawn to toxic substances the way that humans are interested in alcohol. As it turns out, dolphins are guilty of this, too. Of course, animals don't process ideas like "drug abuse" the same way we do, but it seems to be a repeated behavior.

  Dolphins have been seen playing with toxic pufferfish, passing them back and forth like a beach ball. Pufferfish release a foul, dangerous substance when threatened, so the dolphins ingest it as they play with the pufferfish. Large amounts of this toxin can be life-threatening, but small amounts only put creatures in a "trance-like state."

  According to zoologist Rob Pilley, dolphins in a BBC documentary were seen mesmerized at their own reflection on the water's surface after biting a pufferfish.

  (#4) Bottlenose Dolphins Attack Porpoises For Fun

  Dolphins regularly eat fish, which is something most people are comfortable with. Yet, it's a bit more unsettling when they hunt animals closer to their own size. Researchers have witnessed bottlenose dolphins throwing and "attacking" porpoises. Dolphins don't eat porpoises, but they still bite them, toss them, ram into them, and sometimes even kill them. 

  Scientists have observed porpoise carcasses washing up on shore with scars that look like dolphin teeth marks. It's difficult to know the exact reason for these behaviors. These attacks could be related to territorial behaviors, a sense of competition, or just a fun activity. Either way, their body language displays that it's likely something dolphins enjoy doing, despite how much it scares humans.

  (#11) Male Dolphins Form Homosexual Relationships To Pursue Females Better

  Janet Mann, a professor of biology and psychology at Georgetown University, has closely studied bottlenose dolphins and their relationships with each other. She discovered that male dolphins spend most of their lives with each other, forming long-term relationships that differ from the ones they have with females. In fact, before mating with the opposite sex, both male and female dolphins often show homosexual behaviors toward each other. Yet, this doesn't mean they're considered homosexual creatures.

  Instead, male dolphins likely have sexual relationships with other male dolphins for their own personal gain. Those behaviors help the male dolphins form closer bonds with each other. Thus, when they're ready to mate with a female, they can find her and "aggressively herd" her together, since that's a mating ritual that works best with several males involved. The homosexual behaviors of most dolphins ultimately result in offspring with the opposite sex eventually.

  (#9) Dolphins Commonly Carry STDs

  Like many animals, dolphins usually carry sexually transmitted diseases like genital warts. When you think about it, it makes sense considering that dolphins don't know how to use protection like humans do. They don't think about the consequences of intercourse, which leads to STDs being passed frequently in the animal kingdom.

  However, research suggests that some STIs in humans originally came from animals. That's yet another reason to keep your distance from wild dolphins.

  "Two or three of the major STIs [in humans] have come from animals. We know, for example, that gonorrhea came from cattle to humans. Syphilis also came to humans from cattle or sheep many centuries ago, possibly sexually," said Alonso Aguire, a vet and president for conservation medicine at the Wildlife Trust.

  (#2) Wild Dolphins Have Shown Signs Of Sexual Aggression Towards Humans

  Do dolphins sexually attack humans? Many videos, including one posted to YouTube by Michael Maes, have shown that swimming and diving with dolphins might not be as innocent as you'd think. Divers have seen dolphins climb on top of humans, and many even appear aroused. While these behaviors are disturbing to us, they aren't classified as "rape." Since dolphins don't understand the concept of consent like we do, their intent may not be malicious, and we can't assume why they're doing it. Yet, it's a surprisingly common behavior.

  In fact, authorities have warned swimmers of sexually aggressive dolphins in certain bodies of water, including Weymouth Harbor, England. While it's unlikely that these sea creatures are trying to have full-on intercourse with humans, these events can be horrific and could lead to injury or drowning.
