Another view of the male M. mars.  This image is a frame from a film sequence in which the female has just walked down to the base of the tree trunk, and the male is proceeding to follow.  Rhinoceros beetles are heavy and rather slow, but they have very energy efficient muscles, and can keep moving for long periods without becoming exhausted.

A close-up of the male's head.  The left eye is visible here as the large, dark sphere located just under the cephalic horn's base end.  Using its sensitive antennae, smell is perhaps the adult rhinoceros beetle's most powerful sense.

A frontal view of the male's head.  Here, you can see the ring of brown setae that surrounds the head where it joins the thorax, a feature common to all dynastinae.

An M. mars perched on a log.  Rhinoceros beetles are the strongest animals in the world in relation to their size, and one of this bulk can push a 2 lb. log out of its path with ease.
