Hi, I have a few questions about mantis shrimps.

Where can you find them in Hawaii?

How many species live in Hawaii? Also, can you name some of them and give us some information about them.

How can you catch them safely?

There are some videos of Dr Roy Caldwell catching them at low tide on YouTube. These were mostly Pseudosquilla Ciliata, an active spearer type mantis. You can also find O. Brevirostris at greater depths (below 10m). Gonodactylaceus Falcatus are also a cavity dwelling species in Hawaii. They were introduced though, not native. I'm sure there are other species, check Roy's List for Stomatopods for more information on that.

There are different techniques for catching different species of mantis shrimp. O. Brevirostris would have to be caught on a SCUBA dive and would probably be pretty difficult. This is why you don't often see them in the hobby.

You might be able to wade out and inspect various rocks for cavity dwelling species. Just be careful not to put your hand over the burrow entrance. The use of a small net is sometimes effective on reef flats at low tide. Just get creative!

Are there any DIY mantis shrimp traps? If so, can you show me how to make them.
