<div class="tree_txt_unlinked"><p>The subfamily Atelinae contains the three largest platyrrhine genera, well-known for their long prehensile tails: <em>Ateles</em>, <em>Brachyteles</em>, and <em>Lagothrix</em>.
Their prehensile tails have tactile pads with friction ridges similar
to finger prints on the ventral surface. Species of this subfamily
differ in their tail use for foraging and locomotor activities.
Anatomically, the Atelinae show many similarities to extant apes in
their axial skeleton, likely related to their use of suspensory
behaviors. Also related to suspensory behaviors, members of Ateline
often have reduced, poorly defined thumbs, which in turn allow the other
four digits to form a "hook" for efficient arm-swinging during
brachiation.</p>
