THE DEVELOPMENT OF THE ANDROGENIC GLANDS OF A PROTANDRIC SHRIMP

Abstract

1. The androgenic glands of the protandric shrimp, Pandalus platyceros, are shown to originate from a region of the sperm duct epithelium that will later differentiate into the ejaculatory bulbs.2. The disappearance of the androgenic glands at the time of sex transformation appear to be related to gonadal function and the secretory activity of the sperm duct epithelium.3. A developmental scheme is presented for the androgenic gland cells of P. platyceros. The cells are classified into six developmental stages.
