Why can you find, say, sharks teeth on some beaches but not others or sand dollars or conches etc?

Sharks only like to fight on certain beaches. It%26#039;s part of the Shark code.

Tides and Water Currents.





Each beach has different tides and currents, and so some beaches will have some things, while others wont.
Reply:The animals that populate the oceans have their own territories, just as land animals do. So, for the same reason you don%26#039;t find tigers wild in America, you won%26#039;t find certain shells in the water off certain beaches. The water may be too hot, too cold, too salty, not enough, etc. Even the ocean currents aren%26#039;t enough to move these shells from one beach to another without destroying the shells in the process, so you usually will only find local shells on your beach.
