(Order Anostraca):

Noncellular, multilayered structure forming outer layer of body and lining esophagus and hindgut; relatively thin and not calcified. Secreted by epidermis [Stachowitsch, 1992].

(Order Decapoda):

Noncellular, multilayered, relatively thick layer forming exoskeleton and endoskeleton and lining foregut and hindgut. Secreted by epidermis [Stachowitsch, 1992].

(Order Amphipoda):

Noncellular, multilayered layer forming exoskeleton and lining foregut and hindgut. (smooth, spinose, with plate-like projections) [Stachowitsch, 1992].

(Subclass Copepoda):

Noncellular, multilayered, relatively thick layer forming exoskeleton and lining both foregut and hindgut. Secreted by epidermis. Forms plate-like structures (cephalic shield, sternites, tergites) [Stachowitsch, 1992].

(Subclass Mystacocarida):

Noncellular, multilayered structure forming outer layer of body and lining foregut (stomodeum) and hindgut (proctodeum); relatively thin and pigment-free. Secreted by epidermis [Stachowitsch, 1992].

(Class Ostracoda):

Noncellular, multilayered, relatively thick layer forming valved, endoskeleton, and exoskeleton, and lining foregut and hindgut. Secreted by epidermis [Stachowitsch, 1992].

(Class Remipedia):

Noncellular, multilayered outer layer of body; secreted by epidermis and equipped with numerous pores and sensory organs. Also lines foregut and joining dorsal brain to ventral nerve cords [Stachowitsch, 1992].
