| These steroid hormones are produced by the crustacean Y-organs and the insect prothoracic glands. |
| In some crustacean groups appendages have large, flattened exopods, endopods, epipodites, and endites. |
| These differences in number of segments and function of appendages are used to distinguish between crustacean groups. |
| Previous studies suggest that the site of decapod crustacean vitellogenin synthesis is the ovary, the hepatopancreas or both. |
| Don Hoi Lord's namesake crustacean is about four centimetres long and looks like a section of bamboo shoot. |
| Detailed work on a series of isolated crustacean limb muscle preparations showed a consistent pattern of innervation among decapod crustaceans. |
