Thats kind of my point. Collecting is collecting any way u can see it, specially live things. Then ur taking sumthing and putting it to an environment they're not used to. But thats a good reason for licensing, large amount of rock. Collecting sticks? Well, ur not cutting trees, are u? But again, thanx for those who do the dirty, yet fascinating job of going underwater and get those things for us. Would love to see how it really is under there- and get a piece of sumthing, or two.
