Sharks use mental maps to find locations
Interesting article. There appears to be a lot of things we don't know about animals.
I find information like this, that is contained in this link fascinating.

I, too, am fascinated by this - but in humans. I recall a story of some years ago. An old polynesian naviagator was told of an islands location (by his contrempories)where he had never been and a scientific type group asked if he could take them there. He agreed and they set out. I do not recall the time required for trip or how far it was ( I want to say 2500 miles, but that seems awfully long), maybe a 1000 miles. At one point they were under thick clouds for about ten days with no stars or sun visible. The most they got off course was about 40 miles ( according to the GPS that the team carried). Never-the-less, the old navigator nailed the micro-dot within a few miles.

OK so how does a homing pigeon know the way home? Also We have a pair of Canadian Geese that nest every year by a small pond where I work how do they know the way back?

There is an older book I had Called ( i'm pretty sure) East is a Big Bird,, and as best as my memory can recall it is about the polynesians and how they navigated and found the other islands, oft times not evening knowing the name of that island.

I was thinking about getting a new GPS. Maybe I'll just get a shark instead. Programming might be a little tricky, but when he says turn, I'll turn!

like hikenhunter, what about homing pigeons.
When I was a lad (many, many many years ago  ) our next door neighbor raise homing pigeons. Each year he would compete in contests with his birds. They would take them miles away and release them by the clock, time them to when he could record the band on their leg.
How do they know?
I am a believer that everyone has an internal compass, some stronger than others, but that is really limited to direction rather than a specific point.

Does it ever make you wonder what the animals know about us?
My wife used to give me $1.00 each workday for lunch. After a long argument, I won. Now she gives me $5.00 every Monday.

The real problem with that is finding a mounting bracket.

Even with pea sized brains, what do they have to remember? Eat. Swim.
Retired and visiting as much of this beautiful country as I can.
