Most commercially important species are in this family . See below . The species in this suborder tend to be larger than the caridean shrimp species below, and many are commercially important . They are sometimes referred to as prawns . Dendrobranchiata, such as the giant tiger prawn pictured, typically have three pairs of claws, though their claws are less conspicuous than those of other shrimp . They do not brood eggs like the caridean, but shed them directly into the water . Their gills are branching, whereas the gills of caridean shrimp are lamellar . The segments on their abdomens are even - sized, and there is no pronounced bend in the abdomen . </Td> </Tr> <Tr> <Th> Pleocyemata </Th> <Th> Caridea </Th> <Td> </Td> <Td> 3438 </Td> <Td> The numerous species in this infraorder are known as caridean shrimp, though only a few are commercially important . They are usually small, nocturnal, difficult to find (they burrow in the sediment), and of interest mainly to marine biologists . Caridean shrimp, such as the pink shrimp pictured, typically have two pairs of claws . Female carideans attach eggs to their pleopods and brood them there . The second abdominal segment overlaps both the first and the third segment, and the abdomen shows a pronounced caridean bend . </Td> </Tr> <Tr> <Th> Procarididea </Th> <Td> </Td> <Td> 6 </Td> <Td> A minor sister group to the Caridea (immediately above) </Td> </Tr>
