Meet the spiny lumpsucker, an unusual new animal at the Newport Aquarium. Their strange name is pretty spot-on as the small fish use a suction cup on their belly to attach to solid surfaces like rocks and seaweeds. That helps to make up for the weak swimming you might expect from a creature that looks to be equal parts golf ball and fish.The spiny lumpsucker is the newest resident at the aquarium, and one of the creatures visitors can stumble upon as part of the aquarium's new scavenger hunt. Starting Friday, the aquarium is challenging guests to an underwater scavenger hunt around the world, searching above and below water for hidden globes. Along the way, you’ll encounter some fascinating new animals recently added to the aquarium.The Underwater Scavenger Hunt is meant to help guests to relax and change their perspective so they don’t miss out on any of the aquarium’s fascinating creatures, aquarium officials say. While searching through the underwater environments for the hidden globes, you’re sure to see everything. “The magic is in slowing down and looking just a little bit closer,” said Rebecca Foster, Newport Aquarium’s Executive Director. “When you do, you’re always rewarded with something special that you may have overlooked before.”The scavenger hunt is free with aquarium admission.
