Question: how to tell the difference between male and female yabbies?
Answer: Males have small bumps that look like pimples near the fifth pair of legs. Inspect the yabby's third pair of legs if you don't see any bumps on the fifth pair of legs. Females have transparent, oval-shaped openings at the base of the third pair of legs. Look for eggs on your yabby if you are unsure of the gender.
