use available evidence to suggest reasons for the differences in range of electromagnetic radiation detected by humans and other animals
Here is an example of available evidence.
Color and Acuity Differences between Dogs and Humans
Dr P’s Dog Training .
Type of animal | Name of animal | Electromagnetic spectrum used | Reasons |
---|---|---|---|
Vertebrate | Human |
visible
|
Active during the day uses colour for perception of objects |
Rattlesnake |
infra-red and visible
|
Active at night hunts in dark burrows | |
Hummingbird |
visible
|
Can detect flowers from over a kilometre away | |
Invertebrate |
Honeybee
|
ultraviolet and visible
|
Can detect ultraviolet markings on flowers and uses polarised light for navigation |
Mantis shrimp |
ultraviolet and visible
|
Can perceive many more colours and escape predation in the well lit waters were it lives |
