sillago,

Mantis shrimp do NOT have binocular vision, they have TRINOCULAR vision. They see MORE colors than we do. The reason and scope of their vision is still unknown. This is from the FAQ

The stomatopod eye contains 16 different types of photoreceptors (12 for color analysis, compared to humanity's 3 cones). Mantis shrimps can thus see polarized light and 4 colors of UV (ultraviolet) light, and they may also be able to distinguish up to 100,000 colors (compared to the 10,000 seen by human beings).

Netdoc,

Try this from the FAQ

How big can they get?

Stomatopods range in size from 1-2 cm to more than 30 cm in the case of some deeper-water lysiosquillids. Smasher types tend be smaller than spearers.

One correction to your post. Mantis shrimp is NOT a 'pistol shrimp'. Mantis shrimp is Stomatopod (fitting name) while 'pistol shrimp is Alpheus.

Both will make snaping noises, pistol's is similar to a cricket (well not technical but you get the idea) and mantis as it attacks it's prey. However if the mantis shrimp has spears you will likely hear NO noise at all.

Pistol shrimp looks like a normal shrimp/crayfish while mantis shrimp is distinctly different.

Thanks Ed for the correction. I should have been more clear and done my research! What I meant is that some folks get the two shrimps, Mantis and Pistol, confused. I didn't know about the spear thing!

Hello,

Not a problem! I had to go back and edit several of my posts due to inaccuracies.

Both pistol and mantis are preditors. Pistol shrimp will click their claws and stun the victims with sound. Both are highly sought in the aquarium industry as both are interesting reef creatures.

Thanks for the info Blacknet
Another thing about them is that they are apparently marketed as a food source and are supposed to taste like lobster (that's what I hear! Never tried them myself personally...not sure if I'd want to at the moment) :mute:
