Good sources for underwater monsters?

[Vraille Darkfang]

Both Creatures of Freeport by Green Ronin

and

Monsters of the Boundless Blue by Goodman Games (Wanderer's Guild)

Are pretty much Marine/Coastal in regards to their monsters.

Both I have & Think are good. (I'm not sure if they are 3.0 or 3.5)
