[12:11.68]Disguise
[12:13.16]Many species of animal practise tactics to disguise their appearance,
[12:18.17]usually by blending in with their environment.
[12:21.78]Such tactics mainly depend on the physical characteristics
[12:26.23]or behavior of a species and its enemies.
[12:30.10]Usually environmental and behavioral factors can cause species
[12:35.08]to employ a variety of tactics.
[12:38.00]And the most common one is background matching,
[12:41.17]in which a species conceals itself by resembling its environment.
[12:46.30]In its simplest form, animals such as deer and squirrels
[12:50.49]resemble the earth tones of their environment.
[12:53.94]Another important tactic is to have disruptive color and pattern.
[12:58.67]This form of disruption causes attackers to misidentify what they are looking at.
[13:05.13]Many butterflies have large patterns on their wings,
[13:09.39]which may misdirect attackers from the soft, vulnerable part of their body.
[13:15.22]Actually disguise can be practised by both prey and their enemies.
[13:20.66]So it may help prey to avoid their enemies
[13:23.74]while the latter may also sneak up on their prey with this tactic.
