Then, of course, there was the stone fish. I’m telling you, if I hadn’t been paying attention, I would have swum right past it. This fish was perfectly camouflaged against the seabed, blending in so well with the surrounding rocks that it took me a moment to even realize it was there. Stone fish are known for being highly venomous, but as long as you leave them alone, they won’t bother you.
That's a fish ? I thought, those small fishes (boxfish) are playing with that stone. The size of that stone (fish) seems big, how dangerous it is in terms of attack ? Does it move fast ?
Can anyone dive or it needs some skills ? You seem to be very knowledgeable about under the sea. And that sea urchin looks scary, like a snake.
