This video shows how tangs, and fish in general, travel in schools of several hundred(s) of fish. We believe this may be the Caribbean Blue tang but this is not certain. The video was taken near Roatan, Honduras so it is definetly a Caribbean Ocean fish but the Caribbean Blue tang is seldom seen in groups of more than 10 or so individuals. Although the species of fish is uncertain, it is still a great showcase for the schooling behaviour of fish.
A video filmed by Vollie Ray near the island of Roatan near Honduras. You can see more dive videos at Vollie's site (http://www.vollieray.com). The video is what I believe to be a Green Sea Turtle, Chelonia mydas. Along for the ride is what looks to be a remora. Another interesting story is the remora, apparently they have been used to capture turtles by tying a rope around their tail and releasing them near a swimming turtle. The remora will then attach itself to the turtle's back at which point both the remora and the turtle can be hauled into the boat. You can read more about this on Wikipedia at http://en.wikipedia.org/wiki/Remora.
Clownfish, with their clown-like markings and waddle-like swimming motion are truly the clowns of the sea! This video contains many different kinds of clownfish as well as general aquarium care information for the "clown" in all of us.
