Friendly Or Frightening? 11 Creepy Facts About Dolphins

Dolphins are praised for their intelligence and apparent friendliness. They are loved worldwide because they are playful and have a certain thing that makes them stand out. And while they can do a lot of interesting things and have a lot of good qualities to them, dolphins also have a dark side to them. A very dark side. And while not all dolphins do these bad things, some of them do especially male dolphins.

BEWARE: you’ll never look at dolphins the same way again after you read this. You’ve been warned! Dolphins might seem like happy, loveable creatures that like to play with humans but the reality is something from the land of nightmares.

1. Dolphins can get sexually frustrated and if this happens they go wild

dolphinsDolphins have been known to go on killing sprees (usually attacking porpoises) when they are frustrated sexually. In most cases, the attackers are young dolphins that will ram the poor porpoises until they are dead. Why do they do this? It seems because dolphins don’t have thumbs so they can’t, well, get rid of their sexual frustrations like we humans do. So, instead, they ram porpoises which seems to have a similar effect? They have also been observed to play with the corpses of their kills (porpoises) so there’s that. If you thought dolphins are nice and cuddly, think again.

2. When they’re not out killing poises they might try groping humans

3. Dolphins often kill their own offspring just so they can mate with their mother!

From what we know, dolphins are among the few animals that kill for fun. Male dolphins kill their babies in an attempt to get their females to once again want to mate with them. It’s an ingenious (although deadly) strategy.

4. Dolphins have been observed killing baby porpoises

5. Sometimes dolphins just attack or kill for fun

They’ve been observed picking on smaller creatures with no apparent reason. You might not have expected the loveable dolphins to do such things but they do.

6. Dolphins can be very aggressive sexual-wise

Yes, you might have heard this before but Dolphin Attacks on Woman is a real and serious thing!

7. Dolphins can stay awake for days or even weeks on end

8. Dolphins hunt both for food and for the hunt

They like to hunt in pairs and find new and inventive ways to catch their prey. It seems they really like hunting, just like hunters who hunt for pleasure not because they need to.

9. Dolphins have STDs and lots of them

Other interesting facts about dolphins

Dolphins can use tools

They have been seen picking up sponges and adding them to their snouts in an effort to (probably) protect themselves when going into hard to reach places or places that could hurt them otherwise. And we’re sure they use other tools as well but we just haven’t noticed it.

Each dolphin has his own personal whistle that others can recognize!

And dolphins recognize one another using these whistles. Scientists are studying and recording all the whistles and sounds dolphins make in an attempt to figure out their language. Could we one day learn to speak to dolphins and understand them?

We hope you’ve learned a few things about dolphins and that it wasn’t too upsetting to learn they do have a dark side to them. They have been positively portrayed by the media but it would have been better to know the full story, the good, the bad and the ugly. And again, there are plenty of videos online to show their dark instincts if you’d like to see for yourself.
