Advertisement I'm adding my account to the general knowledge regarding United States domestic Scolopendra in captivity. I almost didn't purchase the polymorpha, thinking it somehow wasn't as sexy or interesting as my Scolopendra heros. So glad I did! The polymorpha is out so much more than the heros, who is almost always curled up below the soil under the water dish. I also rarely get to see the heros eat, whereas the polymorpha only rarely refuses a meal. Also, the difference in price is considerable, with the polymorpha being a budget-friendly purchase at $24 and heros hovering around the $80 - $100 mark. Eventually the heros, at 7 inches, will grow larger; but the polymorpha, pretty slow growing at 6 inches, has been an active and charming edition to my collection. For anyone considering it, I would highly recommend the polymorpha.
