MANTIS MURDER SHRIMP (Slow Motion)

Octopus Plays With Coconut

Thanks for the article. It kinda reads like an add for Jennifer Mathers' 'octopuses are smart' book. Her 2008 Consciousness and Cognition paper does a better job at laying out the most cephalopod behaviors impressive behaviors:
http://www.sciencedirect.com/science/article/pii/S1053810006001504
. Don't get me wrong; I think cephaolopods totally awesome, but I don't see the case for them being cognitive leaps and bounds above other invertebrates. The behaviors that they are capable of are found elsewhere among inverts, yet people (often encouraged by Mathers or her coauthors on that book) seem to imply they are basically eight armed dogs of the sea:

Behavioral conditioning in the lab (which Mathers likes to call "learning") - Bees, butterflies
Moving objects to close off burrows - mantis shrimp
Carrying objects as temporary refuges - crabs
Individual recognition - wasps, lobsters?, mantis shrimp.
Complex spatial navigation - ants, bees.
Learning via observation - I'm not aware of other inverts that do this, but the cephalopod evidence is also pretty weak.

Maybe there are some more recent, and more convincing results?

How Animals See The World

Hmm. This could have been done better. I was hoping to see visualizations of:
* Birds' extremely high-speed vision; fast enough to fly through trees' foliage.
* Jumping spiders with 2 focusable main eyes and 6 other eyes.
* Mantis shrimp with their 6+ receptors, including UV, IR and polarization.

True Facts About The Mantis Shrimp

Turning Sound Into Light - Minute Physics

grinter says...

To clarify, mantis shrimp don't create sonoluminescence in the same way that pistol shrimp do, by "squeezing their claws together". They create it when the smack things, like snails, really hard with their raptorial appendages.

Another interesting angle to think about: We have all of this scientific interest in sonoluminescence, and the host of cool hypotheses mentioned, not just because it's cool. ..but because, among other things, the Navy REALLY wants to understand the process of cavitation, and throws money at research on the subject. Why? because ship and submarine propellers also create cavitation, and they want to create war machines that are not loud and whose propellers last longer.

World's Deadliest - Mantis Shrimp

Mimic Octopus and Jawfish

Rad.
Lembeh is great! When you first go down, you don't see anything.. just "muck".. but then you notice that everything you do see is a cryptic animal. Every leaf floating by is a fish.. every pebble is the eye of a mantis shrimp. Oh, and there are pygmy seahorses!

"How the mantis shrimp generates the force to do this has baffled scientists for years."

No, it hasn't. They don't need a high speed camera to study the musculature of the club.

Now, who wonders why so many people hold science in such low regard?

Richard Feynman Discusses Science Religion and Fear

What an awesome person.

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..
