migration
the movement of an animal from one region or climate to another for a specific period of time
aggressive mimicry
a technique used by some animals to lure prey to them by mimicking something else
nocturnal
asleep during the day and awake at night
diurnal
awake during the day and asleep at night
hibernation
a resting state of some animals during cold weather when their entire metabolism, including digestion, respiration, and heart rate, slows down
estivation
a resting state similar to hibernation that some animals use in hot weather
camouflage
an adaptation of some animals that helps them to hunt or to avoid predators by having a color that is the same as their environment
protective resemblance
an adaptation of some animals that causes them to look like something else in their environment
mimicry
a type of protective resemblance that causes an animal to look like something that it's predators would rather avoid than eat
self-mimicry
an adaptation that helps to protect an animals most vulnerable body parts from predators by having one body part look like a different body part
warning coloration
a protection adaptation used by some animals that uses color to warn other animals to keep away
