This infographic provides information on how to determine the gender of crayfish. It’s divided into sections with visual aids and text descriptions.

Male vs Female Crayfish:

  • Male Crayfish:
    1. Larger in size when sexually matured.
    2. The claw is larger in female crayfish.
    3. Narrow abdomen.
    4. Strong and fully developed Gonopod.
  • Female Crayfish:
    1. Not as large as the male.
    2. The claw remains comparatively shorter.
    3. Wider abdomen for storing eggs.
    4. Gonopod is not as developed as the males.

Anatomy of Crayfish: A detailed diagram of crayfish anatomy is provided, labeling various parts such as the walking legs, antennae, swimmerets, and more.

How to tell if a crayfish is male or female:

  1. Inspect the Gonopod:
    • Male: The Gonopod is very developed and large.
    • Female: You’ll barely be able to see the Gonopod.
  2. Male Crayfish Have Claspers, Females Have Holes:
    • In the male crayfish, the fourth set of pereopods (walking legs) has a nodule at the base, known as Claspers. Females don’t have these claspers.
    • In female crayfishes, the third set of pereopods will have two holes at each side of the pereopod’s base. Eggs come out from these holes.
  3. Male Crayfish Are Larger:
    • The infographic shows images of a male and female crayfish, pointing out that males are typically larger when sexually matured.
  4. Claws Are More Prominent in Male Crayfish:
    • Male: Claws are larger and more prominent.
    • Female: Claws are smaller and less prominent.
