fish cant remember anything longer than a few seconds...does this mean they have 2 learn 2 swim over and over?

Answer 1

Swimming is an involuntary action just as breathing and your heat pumping blood is to a human. There was a program a few years back about sharks. A small sharks brain was removed and it remained swimming for over a week it died of starvation. A bundle of nerves in the lower back of the shark controlled swimming (not enough tissue to qualify as a brain). This show also show how sharks use body magnetism to bite prey at the last second when its mouth is open an eyes blocked. The sharks turn their head at the last second away from the bait and bite the idling engine.

if a fishes memory is no longer than a few seconds, why do my fish go mad at 6 o'clock every night, just before i feed them.

Answer 4

Fish CAN remember things!! Fish are more intelligent than they appear. In many areas, such as memory, their cognitive powers match or exceed those of 'higher' vertebrates, including non-human primates." Their long-term memories help fish keep track of complex social relationships. Their spatial memory—"equal in all respects to any other vertebrate"—allows them to create cognitive maps that guide them through their watery homes, using cues such as polarized light, sounds, smells, and visual landmarks.
Dr. Phil Gee, a psychologist from the University of Plymouth, says that fish can tell what time of day it is, and he trained fish to collect food by pressing a lever at specific times. He says "fish have a memory span of at least three months," and they "are probably able to adapt to changes in their circumstances, like any other small animals and birds."
"We're now finding that [fish] are very capable of learning and remembering, and possess a range of cognitive skills that would surprise many people." So no,fish do not have to learn to swim over,and over!!!
