DID YOU KNOW Madagascar hissing cockroaches are ovoviviparous? This means that the young develop in eggs which are hatched within the mother's body. As you can see in this video, nymphs are white initially before their exoskeletons harden. 🎥: Senior keeper Erin #CreatureFeature | California Science Center

Instead of using vocal cords, they are able to make this sound by forcing air through holes or spiracles, found on the side of their abdomen. #tennesseeaquarium #chattanooga #spookyseason #Madagascar #halloween #hissers #insects | Tennessee Aquarium
