Natural  Organic  Captive Born/Bred             10+, 20+ count             ~all our isopods are packed over-counted by at least 10% (mixed size juveniles, of breeding age)            Shop with confidence from the very same invertebrates supplied to stores, rescues and zoos!       Porcellio scaber Calico isopods are a popular color morph originating from the USA, known for their eye-catching hues of pale brown to brilliant orange. In this sex-linked variation, just like in cats, only the females exhibit the orange Calico patterns, while the males remain grey in color. This is due to the gene for the Calico expression being carried only by the X chromosome. So while all males carry the gene, they cannot express it! This makes them one of the easiest isopod species to sex by far! Great for educational purposes!                 Porcellio scaber - Calico Isopods (sex-linked) Difficulty: Moderate Size: .68 inches.
