Shane Ahyong Australian Museum Academia Lobsters are a ubiquitous and economically important group of decapod crustaceans that include the infraorders Polychelida, Glypheidea, Astacidea and Achelata. Caridea Shrimp of the infraorder Caridea are closely related to lobsters and crabs than they are to the members of the sub order Dendrobranchiata prawns Biologists distinguish these two groups based on differences in their gill structures The gill structure is lamellar in carideans but branching in dendrobranchiates The easiest practical way to separate true shrimp from dendrobranchiates is Crustacean larva History of the study of crustacean larva Antonie van Leeuwenhoek was the first person to observe the difference between larval crustaceans and the adults when he watched the eggs of Cyclops hatching in Despite this, and other observations over the following decades, there was controversy among scientists about whether or not metamorphosis occurred in crustaceans, with conflicting Staff National University of Singapore The Department of Biological Sciences evolved from the merger of two of the oldest departments in the Faculty of Science the Department of Botany and the Department of Zoology Botany, founded in , turned in and Zoology, founded in .

Hummerartige Die Hummerartigen Nephropidae sind eine Familie aus der Ordnung der Zehnfukrebse Decapoda Alle Hummerartigen leben marin, sind Teil des Benthos, weltweit verbreitet und sowohl im Schelf als auch in der Tiefsee zu finden Bekannteste Vertreter dieser Arten umfassenden Krebsfamilie sind wohl die Hummer sowie der Kaisergranat.Gemeinsames Merkmal sind die Scheren an den ersten drei _ Cambaroides japonicus Procambarus clarkii Krepsdyr Krepsdyrene Crustacea er en stor gruppe av leddyr.Krepsdyrene er dominerende i havet og omfatter viktige dyregrupper som krabber, reker, kreps, krill, tanglopper, raudte og tallrike andre arter av dyreplankton.De er den mest tallrike av alle grupper av marine leddyr og finnes nr sagt overalt i hav og ferskvann.Enkelte arter lever ogs p land
