[Coral-List] Strange predatory snail question

[Sarah Frias-Torres]

This might sound a bit strange question for the Coral List forum but....some time ago I saw in the Blue Planet Series (or was it Planet Earth Series?), a short video of a marine predatory snail chasing after another snail in a coral reef.The video was quite striking showing how a fast moving (in snail speed limits) predatory marine snail run after another much smaller unsuspecting snail, then launches an attack basically engulfing the unlucky snail  (shell included) with a "mouth" a tube-like proboscis No escape possible. Does anyone know what I'm talking about or point me in the right direction to locate the video clip? Is this behavior also possible in predatory nudibranchs?
