OMSI’s new feature exhibit, Monsters of the Abyss, opens on Saturday, October 4 and will be on view through February 16, 2026.
Dive back in time to explore what lurked beneath the surface at the newest exhibit in Portland—Monsters of the Abyss: Aquatic Predators Past + Present. Meet massive mosasaurs, a spine-chilling Spinosaurus, and bizarre creatures as you travel through millions of years, witnessing the rise and fall of Earth’s most awe-inspiring aquatic creatures as well as their present-day descendants. Highlighted by amazing fossils, daily educational programming, and some unbelievable live animals, this exhibit brings guests face-to-face with the real-life monsters who defy imagination and have inspired myths and legends. You’ll have to see them to believe them.
Most guests can anticipate spending roughly 45 minutes viewing the exhibit, but guests may enjoy it for as long as the museum is open.
