Thanks I was hoping you wouldn't mind. Your Feynman post reminded me how much he rocked.

Incidentally, it's always fun to see when a video (my video! ) hits the top 15, many people hitch on and start posting similar videos. Also my mantis shrimp videos a few days ago. I'm not complaining though as long as it enriches the Sift..

What an awesome person.

Your video, Mantis Shrimp bludgeons crab apart, has made it into the Top 15 New Videos listing. Congratulations on your achievement. For your contribution you have been awarded 1 Power Point.

^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 could take it.


Actually, I'm not so sure. You see that other video where the Mantis Shrimp goes for the fiddler crab and the first thing he does is BANG: big claw amputated?

I'm thinking if this thing has strategies for humans, it's going for the nutsack first.

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

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.

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

Shelia Patek can tell you how it works...

I was expecting some awesome killer strike footage or somethin'. What a tease.

Woo! Cheers.

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

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

Also take a look at Crustacean Wars I where this Mantis casually batters a snail.

We had one of these in our salt-water fish-tank growing up. It is exactly as described. We had some rock that we had gotten in the ocean and it came along for the ride. The one we had was MUCH smaller and never bothered the other fish because once my father saw it, he started feeding it on a stick exactly like the lady is showing.

At night, we would hear this loud clacking coming from the tank, it was the mantis shrimp burrowing through the rock to make his home larger...
