3D Glasses Work On Cuttlefish And It's Adorable:
Every so often, scientists grace the undeserving public with an experiment seemingly designed solely to make us giggle in delight. Without any further ado, Cuttlefish Wearing 3D Glasses: [YouTube Link]
[...] Initial attempts to glue the glasses straight on the cuttlefish (yikes!) led to skin damage, and the scientists solved this by instead gluing little velcro strips (double yikes!) to both their heads and the glasses, so that they could strap them on.
Cuttlefish love to snack on shrimp, and the way they catch them is by swimming forward and backward to adjust for distance, then launching their tentacles at prey from just the right spot. Scientists weren't sure if the cuttlefish would do this for the 3D animated shrimp in their little movie, but they totally did. [...] The cuttlefish adjusted their distance, they launched their tentacles, and even though they came up empty-handed, they proved that scientists were at least on the right track.

have assured me that catfish don't need glasses. It's just the cuttlefish, which apparently aren't good eating anyway.
