Liopluerodon ferox, taking a peek up at the surface in much the same way whales do... considering they and similar species probably occupied a lot of the same niches as whales do today. ^^ Not so much the "Rawrrawrrawr, I have no compulsion to play or make social connections or do anything but kill for I am a scary reptile therefore naught but a scary eating machine water-monster!". Nope, none of that. Just aquatic animoos.
