What are these things!!

Just found two of these under a coral. Any ideas?

I am guessing not nice Polyclad flatworms but the image is too blue for details.

Video or photo under white light would help

Agree

Not the most educated on polyclads so take with salt but I would evict in case it is a leopard.

It is certainly creepy.

Certainly creepy. Gray in color. Could stretch out to 2 inches or more. Looked between a giant flat worm and nudibranch (sp)
