Got some of these on an uncured piece of live rock collected in the Atlantic. At first I thought they were larval mantis shrimp but their behavior was all wrong for mantis shrimp even in larval stage and despite looking like mantids they turned out to be an Amphipod-Caperellid, in the Mayerella genus. I have not been able to pin down the species and likely will not be able to as most of the literature states that a microscope is required to identify the species along with some expertise. Usually a deep water species or at least deeper than the average reef environment most live rock comes from. They can feed on the gills of some tube worms or gorgonians but can also eat diatoms and other benthic plankton. My camera can't do them justice so I include an image taken from the internet. They seem to be feeding and breeding and I suspect that the moment I add the first fish to my little reef they will all be eaten.
Does anyone out there have any of this "pod"???
