To date, there are more than a hundred reported mtDNAs from crustaceans, including 86 from Malacostracans, which is the largest of the six classes of crustaceans and includes extinct and living species, such as shrimp, lobsters, crabs, krill.

Some believe that insects evolved from the an ancestor that gave rise to the malacostracans, a group of crustaceans that include crabs and shrimp, while others point to a lineage of less commonly known crustaceans called branchiopods, which include, for example, brine shrimp.

Similarly, for malacostracan species, the analysis revealed the existence of two main groupings, one consisting of the three Patagonian zones plus Central Chile, and the other comprising Northern and North-Central Chile (Fig.

This phenomenon applies to most malacostracan Crustacea, which begin reproduction before somatic growth is completed (Hartnoll, 1985), similar to apterygote insects and myriapods.

We found that crab antennules, like those of other malacostracan crustaceans, take a discrete water sample during each flick by having a rapid downstroke, during which water flows into the aesthetasc array, and a slow recovery stroke, when water is trapped in the array and odorants have time to diffuse to aesthetascs.

The zooplankton comprised the copepods Temora longicornis, Paracalanus parvus, Pseudocalanus elongates, Centropages typicus, Calanus finmarchicus, and Oithona nana; and the malacostracan crustaceans Crangon crangon, Corophium volutator, N.
