SCRIPT Every day all around us we can see examples of adaptations, within our own species within species of other animals and within members of other kingdoms. Put simply an adaptation is a feature of an organism that gives it some sort of benefit or advantage. They could help it build a shelter find and hunt food protect itself or compete against others for mates, food and resources. Adaptations can help it in a range of aspects relating to its survival. Adaptations can be categorized into three main groups structural or physical, behavioral and physiological. Let's now look at the differences between these groups by looking at some examples. Structural adaptations also known as physical adaptations are physical features of the body that assist in some way with survival or reproduction. Some obvious examples include having horns to defend against predators and to compete against others. Having fins for aquatic animals who need to swim efficiently and having armor to defend against predators, having camouflage that helps you blend in with your environment is also a very useful adaptation to have it can help you hide from predators who might be looking for a quick snack it can also make your braid/ prey harder to see you which allows you to get in close and get a sneak attack. A structural adaptation of a lot of plants is to have brightly colored flowers which attracts insects and assists with the pollination process. Behavioral adaptations are things that the organism does which gives it some sort of benefit and for the most part these are innate behaviors which means they are born with the ability and the drive to do them. Herding is a great example of the behavioral adaptation not only does it help you find food easier as a group but it also helps you spot predators and raise the alarm. Socialization is another important behavior that's observed in a lot of species it allows behaviors to be taught to other members of the same species it allows opportunities for relationships to develop and it promotes cooperation. Setting a trap like a spider spinning a web is a great strategy to try and catch some food. Being the most intelligent invertebrate the octopus is capable of mimicking other animals in order to get closer to its prey . Physiological adaptations are things that the organisms body does without necessarily having to consciously tell it to do so. For example, a distinctive feature of mammals is that the females produce milk which is a nutrient-rich food source for their offspring, it doesn't choose to produce the milk but it just does and in doing so that's helping the survival of the next generation. Producing poison or venom is another example of a physiological adaptation. A snake or a stingray producing venom in being able to inject that into its prey will help it catch it and a toads body producing poison will help deter its predators. In order to summarize what we've covered today have a look at this snail I want you to think of a structural adaptation a behavioral adaptation and a physiological adaptation here are some examples that you could have had and that's it for today I find this topic really fascinating and I hope you did too thanks for watching and I'll see you next time.
