Some species of cicada live as long as 17 years, though most of the time is spent underground. There are two groups of cicadas: annual cicadas and periodical cicadas.

Axolotls (pronounced ACK-suh-LAH-tuhls) are salamanders! Thes amphibians spend their whole lives underwater. They exist in the wild in only one place on Earth—the lake complex of Xochimilco (pronounced SO-chee-MILL-koh), a network of artificial channels, small lakes, and temporary wetlands that help supply water to the millions of residents in nearby Mexico City. Axolotls have long fascinated scientists for their ability to regenerate lost body parts and for their rare trait of neoteny, which means they retain larval features throughout life. Rather than undergoing typical metamorphosis, axolotls keep their youthful appearance, including their tadpolelike dorsal fin and feathery external gills that fan out from the head. As they age, axolotls simply get bigger and bigger, like amphibious Peter Pans. In rare cases, axolotls have matured past the larval stage and emerged onto land as adult salamanders. Neoteny doesn’t affect the axolotl’s ability to breed. Females mate with males and lay eggs underwater. As Mexico City has grown, the lake complex has shrunk and parts have become contaminated, distressing the axolotl population. The introduction of large numbers of carp and tilapia fish, which compete with axolotls for food and also eat axolotl eggs, has further lowered their population. A 2009 survey suggests there are fewer than 1,200 axolotls in the Xochimilco Lake complex. Axolotls feast on a menu of mollusks, worms, insect larvae, crustaceans, and some fish.

Porcupines are lumbering, rotund rodents with needle-like spikes, called quills, covering their back, sides, and tail. A single porcupine can have more than 30,000 quills, which are actually sharp bristles of fused hair. When another animal attacks the porcupine, its quills detach, burrowing into the adversary’s flesh and inflicting painful, potentially deadly wounds. It’s easy to tell when porcupines are mad: They stomp their feet, hiss, and shake their quills, which normally lie flat against the porcupine’s body. While porcupines are rarely aggressive, they’ll defend themselves by charging or swatting their spiked tail at opponents. Porcupines are herbivores, eating leaves, plants, fruit, and the tender layer of tissue beneath the bark of trees. A porcupine can fell a whole tree if it removes too much bark. The head and body of a porcupine is between 25 to 36 inches (60 to 90 centimeters). And the tail can add another 8 to 10 inches (20 to 25 centimeters) to the entire length.
