Seals

»   Seals can sleep underwater and surface for air without even waking.

»   Lungless salamanders are the largest group of salamanders. They have no lungs or gills and breathe through their skin, which must be kept damp to allow oxygen in. If they dry out, they will die of suffocation.

»   Seals can withstand water pressure of up to 850 pounds per square inch.

»   Macaws are the largest and most colorful species of the parrot family.

»   Seals have back flippers that can’t bend under the body in order to walk on land, while sea lions use their leg-like hind flippers to “walk” on land.

»   Made of mud, small stones, straw, and feathers, flamingos build nest mounds that can be as high as 12 inches (30 cm).

»   Mahimahi is dolphin, but not the mammal with the big brain and the need to surface to breath (like Flipper). The mahimahi is a fish, but the United Nations dubbed it “dolphinfish” to end the confusion.

»   Male and female sea turtles are about the same size.
