Greetings Infomaniacs,

On Sunday, my godson and I went to the zoo to check out their Holiday Magic exhibits and light displays. The highlight of the evening was the dolphin show. When they asked for volunteers for a segment of the show, my godson was picked to participate!

The chosen volunteers, along with the trainer, demonstrated how dolphins mimic human behavior. The kids waved their hands, twirled around in a circle and jumped up in the air, and the dolphins copied each of their moves!

My godson was so excited to get up close with the dolphins and was amazed by their ability to perfectly imitate movements by humans. It was very cool.

Enjoy!
Melissa

RANDOM TIDBITS
There are 32 species of marine dolphins, four types of river dolphins, and six types of porpoises. The distinction between dolphin and porpoises is often blurred, but generally porpoises have spade-shaped teeth and blunt rounded faces. Dolphins have teeth shaped like rounded cones set in jaws that extend in a snout or beak.

A baby dolphin is born tail-first to prevent drowning. After the mother breaks the umbilical cord by swiftly swimming away, she must immediately return to her baby and take it to the surface to breathe.

A dolphin's body has adapted to avoid the bends (the formation of air bubbles in blood and tissue as a diver returns to the surface of the water) by completely collapsing its ribcage, forcing the air under pressure out of its lungs and into the windpipe and the complex air chambers that lie below the blowhole.

Dolphins don't have a sense of smell, but they do have a sense of taste and, like humans, can distinguish between sweet, sour, bitter, and salty tastes.

Dolphins also "see" with sounds. They emit a series of clicks and pings that travel long distances through water. When the sound hits an object, echoes are bounced back to the dolphin, enabling it to literally hear distance, shape, density, movement, and texture of an object.

A dolphin can produce whistles for communication and clicks for sonar at the same time, which would be like a human speaking in two voices, with two different pitches, holding two different conversations.

A response to a mistake,
That when offered is suspected,
In desperation it is expressed,
The truth is apparently rejected.
