|| All About The Pygmy Marmoset ||
Common Name: Pygmy Marmoset
Binomial Nomenclature (Scientific Name): Cebuella Pygmaea: "smallest monkey"
Threat Level: Critically Endangered according to IUCN Red List
|| Habitat Information ||
Biome: Dense, tropical rainforests and areas that get a lot of rainfall
Habitat: Pygmy marmosets live mostly in the trees within these rainforests
Geographical Region: Brazil, Peru, Columbia & Ecuador (South American countries)
|| Community Interactions ||
Mutualistic: Pygmy marmosets & the fruit they eat (pollenating the flowers on fruits)
Commenalistic: Pygmy marmosets & humans (kept as pets)
Predator: Pygmy marmosets & ocelots, margays, birds and snakes (predation)
|| Feeding Relationships ||
Pygmy marmosets are omnivores. They eat mostly sap from trees (this is their favorite treat), fruits and leaves but will occasionally eat a small insect/invertebrates.
|| Niche ||
The pygmy marmoset has the job of pollination. Since the marmoset eats the sap from trees and nectar from flowers, when it goes to eat those foods, the pollen from the plants get stuck to its fur and feet. Then, as it goes from tree to tree, it's spreading that pollen so that other flowers and plants can grow.
|| Population Dynamics ||
The Colombian, Peruvian, Brazilian & Ecuadorian rainforests have all been effected by density dependant variables. There are all kinds of diseases that fly around in the rainforests and since the rainforests are so poulated by species, many of those animals and plants are more succeptible to the diseases and can/will die off. Right now, this has not had an affect on the pygmy marmoset population but it still poses a large threat to the species today, especially since the rainforest population is only getting larger. This has most definitely changed the carrying capacity over the years. Since certain species have died off, other species who relied on those species for food now have to quickly adapt to finding a new food source or they will have a smaller carrying capacity because there will be too much of a demand for food and resources that aren't there/avaliable.
|| Human Impact ||
As of right now, humans have not had a large affect on the pygmy marmoset population because most of the pollution that occurs in/near the rainforests are in the bodies of water and the pygmy marmosets spend their time in the tree canopies. Pygmy marmosets have been shown to have a very high tolerance for disturbed and tainted habitats since they acutally prefer flooded areas to call their home. I can infer though, that if we keep throwing out our trash wherever, dumping waste wherever and just not caring about the environment, that could easily and quickly change and humans could easily become the highest threat to the pygmy marmoset population.
|| Cells ||
The pygmy marmoset goes through cellular respiration like any other animal or human
The pygmy marmoset does not go through photosynthesis but depends on it because almost all of its food supply goes through photosythesis and depends on it for life.
Pygmy marmosets do not need any specialized organelles to perform cellular respiration. To perform cellular respiration you need to have mitochondrion which then inside, have thylakoid disks & stroma that are required for cellular respiration.
Pygmy marmosets carry out cellular respiration because that process turns glucose into ATP which creates energy for the cells in the marmoset's body so that it can carry out daily, bodily functions it needs to for survival.
Pygmy marmosets do not carry out photosynthesis because they do not contain chloroplast or therefore chlorophyll, and can find their own food in the environment they are in to support themselves.
|| DNA & Cell Reproduction ||
Pygmy marmosets reproduce sexually like most other mammals. Their cells go through both mitosis & meiosis just like special cells in humans! Females breed a few times a year to ensure that there will be great offspring that will keep the species going for generations but only the dominant female in each group/family will breed. Most commonly, the female gives birth to fraternal twins. One intersting thing I found about mating & raising young was that not only will the mom & dad raise the young but the whole group of marmosets will assist in raising, carrying & feeding the young.

|| Adaptations ||
- Pygmy marmosets can turn their heads 180 degrees to scan the environment for predators and to help them with cracking into the bark of trees to get to the sap
- Pygmy marmosets have adapted narrow and elongated teeth so that it makes it easier to get into the barks of trees to get to their favorite food, the sap. The elongated teeth make it easier to cut into the wood and get a straight flow of sap from the tree to the marmo
