Angelfish (Pterophylum scalare) will learn and remember who feeds them. They can even be trained to come to their names and have been known to recognise (hide from) people who have frightened them. They can learn to do many other things too. So I guess the memory 'span' of an Angel fish is probably as good as and spans a time as good as its' lifetime which can be around 10 to 15 years. (I have heard of Angels living for 20 years)
It depends on the human's memory strength.
They have an extremely long memory span. Donkeys can remember things for their entire lifetimes and often show this by behaving in specific ways.
A finch's memory span is within a couple of months.
456 years
the normal memory span for a person is about 30 years
Sharks have been shown to exhibit long-term memory capabilities, with some studies suggesting they can remember information up to several years. However, the exact duration of a shark's memory span can vary depending on the species and the specific context.
It actually has a memory span of a month. I read this in a book. Don't blame me if it is wrong. This is because a goldfish always recognizes it's owner, knows when it should be fed. It only has the attention span of 3 seconds.
A cat's memory span is typically around 16 hours, which is relatively short compared to other animals. Some animals, like elephants and dolphins, have much longer memory spans that can last for years.
They might. The normal life span of an angelfish is 10-15 years. So it mostly depends on how well you take care of it. :-) hope I helped.
Giraffes really have a very short Memory Span ..so short that it would be difficult to say.
about 6 in
A monkey's memory span varies between the different types of monkeys, so there is no single answer to this question. In general, a monkey's memory span is comparable to that of a child of about 7 or 8 years old. It can remember things for months, even years, and a monkey's short-term memory is usually very good.
