Spiracles on stick insect
Référence de la vidéo 11933061
| Close up of the abdomen of an Annam stick insect (Medauroidea extradentata) featuring a spiracle, a fraction of a millimeter in diameter, located near the joint of one of the abdominal segments. Spiracles are holes which connect to an insect's tracheal, or reathing, "" system that consists of tubes that carry oxygen to all parts of an insect's body. The spiracles open and close by way of valves that are controlled by muscles. Spiracles are lined with hairs that filter out dust as air enters. In this view, the abdomen throbs as the insect pumps fluid and air through its body." | |
