Even brightly colored animals are hard to see in certain environments. Others look like their surroundings. Armor, bad smells, and bad tastes protect goliath beetles, skunks, and butterflies. Insect eaters prey as efficiently as leopards and sharks. Starfish wait for their prey, but piranha attack in schools.
Spiders keep the fly and mosquito populations down.
Kookaburras, crickets, gibbons, and rattlesnakes communicate with sound. Deer, eagles, and hawks give visual signals. Ferrets leave their scent. Bees dance to tell the hive where to find flowers. Snapping turtles, fish, pelicans, and vampire bats catch prey with their specialized mouths.
