What is Aposematism in Biology?

  • Also known as warning colouration, this refers to how animals change colour or adapt physically to counter threats from various predators.
  • Such features warn predators to refrain from attacking an animal as it is either poisonous or possesses other self-defence mechanisms to harm the predator.
  • In contrast to other protective mechanisms, which usually try to hide the creature from potential predators, aposematic warning mechanisms try to grab the attention of predators by advertising their dangerous characteristics.
