Cool video, but what an annoying watermark.

^I know, right? Couldn't they have put it in the corner or along the bottom, at the very least?

Christ! Three mantis shrimp vids in 24 hours? Do we need a *mantisshrip channel now?

and yes... I'm upvoting because mantis shrimp > everything else (except bacon)

Awesome boxer, but he's got nothing on Pistol Shrimp.

...but the Mantis Shrimp is pretty amazing. Something about a Hyperbolic Paraboloid Spring or something...

Shelia Patek can tell you how it works...

Actually, that Patek talk mentions the cavitation generated in mantis shrimp strikes.... this is the same phenomenon that gives the pistol shrimp it's power.

Even though the punch of the Mantis Shrimp is very impressive and most talked about, I think its eyes are most impressive.

http://en.wikipedia.org/wiki/Mantis_shrimp#The_eyes
Mantis shrimp possess hyperspectral colour vision, allowing up to 12 colour channels extending in the ultraviolet. Their eyes (both mounted on mobile stalks and constantly moving about independently of each other) are similarly variably coloured, and are considered to be the most complex eyes in the animal kingdom. They permit both serial and parallel analysis of visual stimuli.

Rows 1-4 of the midband are specialised for colour vision, from ultra-violet to infra-red. The optical elements in these rows have eight different classes of visual pigments and the rhabdom is divided into three different pigmented layers (tiers), each adapted for different wavelengths. The three tiers in rows 2 and 3 are separated by colour filters (intrarhabdomal filters) that can be divided into four distinct classes, two classes in each row. It is organised like a sandwich; a tier, a colour filter of one class, a tier again, a colour filter of another class, and then a last tier. Rows 5-6 are segregated into different tiers too, but have only one class of visual pigment (a ninth class) and are specialised for polarisation vision. They can detect different planes of polarised light. A tenth class of visual pigment is found in the dorsal and ventral hemispheres of the eye

Yes, but how does it taste?

^excellent actually! Like pre-buttered lobster.

..or, if you are wondering about their chemosensory abilities, those are excellent as well. Mantis shrimp can actually
identify the specific 'odor' of other individual mantis shrimp . They are aversive in the presence of the odor of animals to which they have lost conflicts, and bold in the presence of the odor of an individual they have defeated in the past.

I love how they added the cork-gun sound effect!
