Natural Camouflage
|
||||||||
| We are not the only ones that can easily recognize a fish from its silhouette. Most fish predators are very good at this as well, which led several species of fish to develop ways to camouflage their shape. This fact suggests that shape information is extremely useful for recognizing certain objects. |  |

Since we know that the predators of camouflaged fish are still able to catch their pray -- although probably not at the rate they would like -- we can imagine that they either recognize their prey using other sources of information, or that their mechanism for inferring shape only works well under certain favorable conditions (e.g., simple backgrounds). |
