PBL #1: Evolve a Primate!
Species Name: Crescens ignis
Common Name: Fire Crescent Monkey
Geographic Distribution: Crescens ignis are native to regions in the heart of the Amazon’s tropical rainforests. They live in highly arboreal where there are seasonal changes in rainfall and temperatures. According to Fragaszy (1950), with such a highly arboreal area these monkeys are able to “use all levels from the canopy to the understory, going to the ground to drink, forage or travel” (p. 1). These “New World Monkeys” are part of the Creschini subfamily and are closest related to their ancestors, the White-fronted Capuchins, or Cebus albifrons.
Physical Description: Fire Crescents are smaller primates that range in size between 7-11 lbs. Their name comes from their long and soft dark red-orange fur and a black spot on top of their heads in the shape of a rear-facing crescent. The Crescens ignis have a lighter orange belly that extends to the face with large forward-facing eyes and flat noses. Their heads and brains are large for their body and the ears are small, short and round. Sexual dimorphism occurs …show more content…
What makes this primate unique is that, because of their large sized brain, they are a very intelligent. Their self-defense mechanisms show their abilities to think fast and make good decisions in any situation. Since Crescens ignis are a smaller species, they are easily preyed upon by a variety of Amazonian animals including snakes and crocodiles. Because of this, they have developed an advanced mechanism makes Fire Crescents less fearful of predators while in the lower canopy during the day. When threatened by a predator, they grab something nearby (usually stones, dirt, or branches) then use their strong limbs to jump up to 5 feet in the air to escape predation while throwing what they snatched at their predator for deterrence and
