Here's a fun bit of trivia about dolphins. Have you heard this before?

Haha. Dolphins are incredibly smart. Who knows? Maybe that's what they're thinking. "oh, we get free food for swimming around" What if we got free food just for walking around? I wish I was a dolphin.

But really... dolphins are really intelligent. They can recognize themselves in a mirror, which few other animals can do. Also, they create their own entertainment by blowing air rings.

that's not true about a cats urine and i believe dogs,monkey,etc. have sex for pleasure. Have you never been to the zoo the monkeys masturbate lol. I also feel that this is contradicting itself because you claim earlier that pigs have an orgasm for 30 minuets. Now an orgasm is the physical and emotional sensation experienced at the peak of sexual excitation, usually resulting from stimulation of the sexual organ and usually accompanied in the male by ejaculation. This is very well an enjoyable and pleasurable experience. Now you later on say humans and dolphins are the only species that have sex for pleasure. Although there are many humans out there that act like pigs, they are still classified as humans.

wow

thats cool

i knew they where smart but not that smart
