What the Heck is Sexual Dimorphism?
Summary
TLDRIn this educational video, John and Jesse, the red-collared brown lemurs at the Tennessee Aquarium, are introduced. These lemurs are unique among their species for exhibiting sexual dimorphism, allowing easy differentiation between males and females based on their appearance. While the female has a bright red collar, light gray face, and orangish-red fur, the male is characterized by dark brown fur, a jet black head, and fluffy white cheeks. This feature distinguishes them from other lemur species like ringtails and red ruffs, where gender identification isn't as straightforward.

this is John and Jesse they are our red

collared brown lemur and Jesse is our
female red collared Brown lemurs are one

it's very common in some bird species
and you can tell males from females
based on the color of the male's
feathers for these guys the female has
the bright red collar the light gray
face pretty orangish red fur while as
the males are a lot more dark brown with
their jet black head hair and the big
fluffy white mutton chops so it's very
easy to tell males from females in this
species which actually makes them
different from the other two species of
lemurs we have here our ringtails and
our red Ruffs there is no way to tell if
