HYBRID SPIDER MONKEY:  Most Hybrid Spider Monkeys grow to a length of about two feet, not including their tail.  They usually weigh between ten to fifteen pounds when full grown.  The Hybrid Spider Monkey is classified as extremely endangered due to a continuing decline in their overall population.  Spider Monkeys have adapted to their treetop environment by using their tail as an extra limb, this makes them extremely agile when swinging through the trees.
 
 

    GORILLA:  Male gorillas grow to about 6 feet tall and can weigh up to 600 pounds.  The smaller females can reach a height of 5 feet and a weight of 200 pounds.  Gorillas are social and peaceful animals.  But unfortunately, gorillas are losing their habitat to farms and are being poached.  The gorilla population has declined by 50% due to these two factors.
