Members of the science community are having a blast this week on Twitter as they participated in the #CuteOff challenge. Last week, the same community initiated the #JunkOff trend that showed the best and worst of animal genitalia, but this new photo challenge is a lot easier on the eyes.

Scientists shared photos of some of the cutest creatures they have encountered in their line of work, and having access to some of the world's most unusual species, they also got to share a different version of what "cute" means in their world.

The National Science Foundation presented the most adorable loris, and there are, apparently about 25 species of this cuteness!

This scientist showed off a tiny cuttlefish called the Sepiola atlantica. Look at how small it measures!

Spiders are cute? This entomologist thinks so!

She shared another one photo of a cute bug who thinks it's a reindeer.

Aww, this Pteromys momonga! Don't you just wanna keep it warm with a blanket?

This guy easily wins the cuteness crown hands down...

But this guy may steal the crown from him!

What about this gecko? It's as if its waiting for someone to adopt him. Look at that smile!

The Smithsonian also joined in the fun and shared a couple of rays from Chesapeake Bay

Check out the rest of what these scientists have shared by following the #CuteOff hashtag on Twitter.

Scientists have also participated in other Twitter photo challenges in the past, such as the #FieldWorkFail challenge and the #DistractinglySexy challenge, as reported by HNGN.
