Previous studies suggest that the site of decapod crustacean vitellogenin synthesis is the ovary, the hepatopancreas or both. |
These steroid hormones are produced by the crustacean Y-organs and the insect prothoracic glands. |
The artificial fly represents a food item be it insect, crustacean or smaller fish. |
In some crustacean groups appendages have large, flattened exopods, endopods, epipodites, and endites. |
With a center core, the darker core areas appear like fish egg vitellus and crustacean inner organs. |
If this protein evolved with the faster crustacean rate, the estimated time of divergence is even more recent. |
