We found this little guy (Live Coral) on the beach of Andaman Islands (India). Our local guide told us that we need to whistle to him in order for him to poke his head out. Seems like he was happy to see us.
& Nope he didn’t bite
I took this pic while on a camping trip to Tobermory, Ontario. This guy and his friend had a very good understanding between themselves. He just used to point to the spot he wanted him and he would immediately comply and after taking few pics the guy would walk down to his dog and show him the pics.
