mantis shrimp brain

[Opcn]

If learned components came into the test I would imagine that they would invalidate the test. IQ tests for humans are based on learned behavior, which in a sense invalidates them, since two individuals of equal brain power can have been exposed to different sets of information, thus preparing one individual more than the other for a subjective measure of intelligence.

So giving a stomatopod an "IQ" test would have to include not exposing the animal to HOW to accomplish the test. That is in octopus do not do the same IQ test twice or let another octopus see the first octopus open the jar.

I imagine on would have to start with a mantis shrimp egg to eliminate this invalidity.

my peacock i think uses tools. i put cubes of food in front of the powerhead, he used to have to swim after them daily to eat. after a few weeks of this he made a wall out of rubble and the cube hits that and he just walks over to it.

 

[Bubbashrimp]

Thats awsome, do you have any photos or videos of this wall he made?

Do you think if you take the wall down that he will build it up again?

 

[rekn]

no i dont but ill try taking apart his wall.

Wall-building is a typical behavior for an Odontodactylus (several species) attempting to construct a burrow. THey will build a wall next to another object, or two walls parallel to one another. In the process they wil deepen the trench at the base of the wall and then roof over the top creating a burrow. It often appears that evolution has selected for behavior that utilizes the concept of a Keystone.

well chuck the wall building idea to the scrap heap it appears to be instinctual. I would still like to see video of this behavior if you have it

hes never slept behind it or on it. his burrow is actually on the other side of the tank.



i took down his wall and this morning it was back up.

he was very upset it seemed. was putting a few rocks back in place and when he saw that i was looking he would set it down, turn his body and then use the ....appendages under his tail to kick up dust and shoot the rock against the glass

The fanning behaviour using the pleopods to shift sand is the trenching behavior I mentioned. Bigger material that can't be fanned away is then picked up using the maxillipeds.
