3.1.27. Sex Change

In some shrimp species, it is common for the shrimp to change sexes as they age. The Aesop Shrimp (Pandalus montagui) start as males and change to female after 13 months. They are found in the Atlantic Ocean. The Oregon Pill bug (Gnorimosphaeroma oregonense) is one of the only crustaceans to hatch as females and after maturity, become males. It is advantageous for males to mate when at a larger size to fend off competition from other males. The mature males mate with the less developed females.
