456 years for most sharks
A finch's memory span is within a couple of months.
The goldfish is often said to have a very short memory span, lasting only a few seconds to a few minutes. However, recent studies suggest their memory could be longer than previously thought.
Contrary to the myth that goldfish have a 3-second memory, research suggests that goldfish can actually remember things for months. They have a memory span of about three to five months and can be trained to recognize different signals and cues.
A Short haired hamster has a memory span of a few days to a few weeks. They may remember familiar scents, sounds, and routes within their habitat, but they do not have long-term memory like humans. It is important to provide a consistent environment and routine to help them feel safe and secure.
A chicken usually has a very long memory for it's "mother" (the one it see's for the first time), and enviornment. SO.. I would say up til' the day they die, but if you abandon for a while they're memory might be fuzzy so do a routine you used to do with them and they will probably pull through. (: Hope i helped?

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.
20 to 30 years
A finch's memory span is within a couple of months.
the normal memory span for a person is about 30 years
The average life span of a shark is between 20 and 30 years. This lifespan applies to the sharks in the world. Domesticated sharks ave got a different life span.
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.
20 to 30 years
Giraffes really have a very short Memory Span ..so short that it would be difficult to say.
