Anyone see the mark on the shark in the 2nd season of Lost?

on the tail when sawyer and michael are in the water like on the small part of the raft and theres a shark in the water...if you see it on DVD or like with Tivo slow it down when it shows the shark underwater looking up and it has The Dharma Initiative mark on the underside towards the tail...anyone else notice this? Secondly, any speculations as to what this could mean?

i saw it. they probably branded all the animals in their experiments. stranger than the shark is that it appears on the plane-maybe the plane is owned by dharma

yeh i also noticed the Dharma Initiative mark on the shark. yeh the Dharma sybol was also on the plane, and an ad over here in australia for the third series shows about 2 seconds of footage of ben aka henry gayle as a person who checks your bags in at the airport, so it coud be likely that Dharma did bring the survivors to the island
