For years scientists told us what we wanted to believe - that fish have short memories only lasting one lap of the fish bowl. Now the truth has got out. They are intelligent creatures who can learn to do things and can even deceive other animals. Once attacked, if they escape, they remember which predator tried to kill them. Unlike humans, however, there is a cost when they use their intelligence. If they are given one fish for food they are very efficient in catching it, but if given two types of prey they apparently become confused and their effectiveness declines. Fish interact in a social way. They recognize familiar others and modify their behavior accordingly. Siamese fighting fish will take advantage of a weak fighter by observing fish fights and readily attacking the weaker fish. Fish that clean others act busy when potential "customers' are watching. In a way they advertise. The myth about fish having no memory or even intelligence is most likely promulgated to ju...

Hunting animals don't just eat what they "bump into". They select "who" they need to eat to maintain a healthy diet. This gives them a better chance of growing strong and big so they can reproduce and pass on their genes. A team from the University of Sydney, Oxford University, Aarhus University (Denmark) and Exeter University researched the ground beetle (Anchomenus dorsalis). Beetles were divided into three groups: one had a selection of bugs offered to them; the second group had high-protein food; and the third had high-fat offerings. The latter two groups did not fair very well. Those in the first group did very well. They chose ants, slugs, moths, aphids and beetle larvae as they wanted and produced more eggs than the other two. It was known that herbivore and omnivore insects ate varied diets. This study confirms the view that all animals select their food due to inner craving created by the body based on the body's immediate needs. The pr...
