Irritator

Flash
When Irritator enters the battlefield, it explores. (Reveal the top card of your library. Put that card into your hand if it's a land. Otherwise put a +1/+1 counter on this creature, then put the card back or put it into your graveyard.)

The nostrils of Irritator were shifted far to the rear of the skull, and the secondary palate make respiration possible even if the majority of the jaw was under water or held prey.
