Long Island Sound Fun Fact

Long Island Sound is 113 miles long, 21 miles wide (at its widest) and holds about 18 trillion gallons of water. Its average depth is 63 feet – which is just a little deeper than the height of our IMAX screen! Can you fathom that?!

gray tree frog

Common Name:  Gray Tree Frog

Latin Name:  Hyla veriscolor

Size/weight:  Small (1.5 to 2 inches)

Range:  Most of the eastern half of the U.S., and north into Canada.

Habitat:  Woods near swamps, ponds and rivers.

Diet:  They are nocturnal hunters of flies, moths, caterpillars, beetles, ants, spiders, crickets and other invertebrates.

Predators:  Birds, snakes, other larger frogs. (Fish eat the tadpoles.)

Description:  Usually blotchy gray but also shades of brown and green. They can change their color to match their surroundings. Few frogs can do this.  Whatever color a gray tree frog is at the moment, its inner thighs will always be yellowish-orange.  Backs are warty in appearance, although of course those aren't warts.

Conservation Note:  Not considered to be threatened or endangered. However, habitat destruction and human pollutants are contributing to the overall decline of amphibians.
