Science Trek
Science Trek is a place where parents, kids, and educators can watch short, educational videos on a variety of science topics. Every Monday Science Trek releases a new video that introduces children to math, science, technology, engineering, and math (STEM) career potentials in a fun, informative way.[MUSIC] JOAN CARTAN-HANSEN, Host: Not all creature share human's five senses.
Whales and dolphins have lost most of their sense of taste.
Scientists think they can only taste salt.
But, considering where they live, that's probably good enough.
Dolphins also have one of the worst sense of smell.
They lack the nerves that send smell information to the brain.
Rhinoceroses have a poor sense of sight.
They can't tell the difference between a human and a tree from 15 feet away.
Sloths have a decent sense of touch but don't ever pick one up.
They are solitary animals and don't like to be touched.
Touch a sloth and you may feel its razor-sharp teeth or claws instead.
Praying mantis were once thought to be deaf.
But scientists have since found a one-millimeter-long slit in its chest that acts as its ear.
The ear is apparently designed for one thing: to pick up the ultrasonic sounds that come from a bat.
It's how a praying mantis avoids becoming a bat's dinner.
