Sudden yelping in the distance sends a terrified plover into the sky. The chaos grows louder, eventually appearing as frenzied movement among the bushes. A low creature scurries through the brush, pursued by miniature, barking canines with enormous ears. Bat-eared foxes, and they've discovered a mongoose. The foxes spin wildly around the animal as it rushes, growling, through the prickled maze. Adults and young alike dodge and weave as the mongoose attempts to flee through their ranks. Their curiosity is relentless, but they dare not get too close. Finding an opening, the mongoose makes a ...

The spadefoot toad is a relatively moist, smooth-skinned amphibian. It has a horny, broad black "spade" on its webbed hind feet, which it uses for burrowing. Approximately 11/2 to 3 inches long, the spadefoot has large, bulgy eyes with vertical pupils. It is usually olive to brown in color with a pair of yellow stripes that extend from the eyes down the middle of the back.

The wrinkled-lipped bat has a relatively small skull, with an extra-small upper premolar. The upper part of its body is covered with short brown fur, and its underparts are paler with gray tips to the fur. Its upper lip is heavily wrinkled, and it has large, round, forward-pointing ears that are joined across the top of its head by a narrow flap of skin. This species has piglike nostrils. Known as a free-tailed bat, the wrinkled-lipped bat is distinguished by a thick tail that protrudes from the membrane stretching between its legs. The bat's wings are an evolutionary modification of t...

The manta ray is flat and wide, with fleshy enlarged pectoral fins that resemble wings. Rough and scaly, the manta has a short, whip-like tail, and gills on the underside of its body. Two cephalic lobes extend from the front of the manta ray's head. Broad and rectangular, its mouth contains small teeth exclusively in the lower jaw. The manta ray varies in color from black to gray-blue along its back. It has a white underside with gray blotches. Manta rays measure up to 29 feet long and 22 feet wide; they can weigh 3,00 pounds.

The Steller sea lion is the largest of five species of seals belonging to the family Otariidae (eared seals). Its yellowish-buff fur is made up of short coarse hair lacking a distinct undercoat. The sea lion's flippers are longer than those of true or earless seals. Sea lions can rotate their hind flippers forward in order to have full use of all four limbs on land. Male Steller sea lions are much larger than females, with males averaging 9 1/4 feet long and females 7 1/2 feet. The average male weighs 1,250 pounds, while the average female is only 580 pounds. Males have a mane ...
