What is the common name of the species Santamartamys rufodorsalis?
Colombian bush rat
Golden tree mouse
Red crested tree rat
Spiny rat
The species Santamartamys rufodorsalis is commonly known as the red crested tree rat due to the distinct reddish crest of fur on its back. Its common name reflects this unique physical characteristic and its arboreal habits. The name was officially adopted when the species was described. Wikipedia
In which country is the red crested tree rat primarily found?
Ecuador
Colombia
Brazil
Peru
The red crested tree rat is endemic to the Sierra Nevada de Santa Marta in northern Colombia. It has not been reliably recorded in any other country. Conservation efforts in Colombia focus on its restricted range in high-altitude forests. IUCN Red List
To which family of rodents does the red crested tree rat belong?
Sciuridae
Cricetidae
Muridae
Echimyidae
The red crested tree rat is a member of the Echimyidae family, also known as spiny rats. This family is native to Central and South America. Members have stiffened hairs or spines intermixed with their fur. Wikipedia
In which year was the red crested tree rat rediscovered after decades without confirmed sightings?
2005
2018
1995
2011
After being thought possibly extinct, the red crested tree rat was rediscovered in 2011 by researchers surveying cloud forests in the Sierra Nevada de Santa Marta. This find renewed conservation interest in the species. Prior to that, there had been no confirmed records since the original description in 1921. National Geographic
What type of habitat does the red crested tree rat primarily occupy?
Mangrove swamp
Montane cloud forest
Dry savanna
Lowland rainforest
The red crested tree rat is found in high-elevation montane cloud forests of the Sierra Nevada de Santa Marta. These wet, misty forests provide dense canopy cover and abundant epiphytes. Their restricted habitat makes them vulnerable to deforestation. IUCN Red List
Which distinctive physical feature gives the red crested tree rat its name?
Red-tinted whiskers
Bright red tail tip
Red patches around the eyes
Reddish crest of fur on its back
This species sports a crest of reddish-orange fur along the midline of its back, giving rise to both its common and scientific names. The crest is more prominent in adults. It may serve in visual signaling or camouflage among bromeliads. Wikipedia
Approximately how long is the body of an adult red crested tree rat, excluding its tail?
20 cm
35 cm
10 cm
50 cm
Adult red crested tree rats have a head-and-body length of around 20 centimeters. Their tails can be as long or longer than their bodies, aiding in arboreal balance. This moderate size is typical for tree-dwelling echimyid rodents. Zootaxa
What is the primary diet of the red crested tree rat?
Carnivorous - small mammals
Piscivorous - fish
Omnivorous - seeds, fruits and insects
Strictly herbivorous - only leaves
The red crested tree rat is omnivorous, feeding on a variety of seeds, fruits, and insects found in the canopy. This diet supports their energy requirements for climbing and foraging in trees. They may also consume fungi and small vertebrates opportunistically. IUCN Red List
What is the current IUCN Red List status of the red crested tree rat?
Endangered
Vulnerable
Least Concern
Critically Endangered
The red crested tree rat is classified as Critically Endangered due to its extremely restricted range and ongoing habitat loss. Fewer than 50 mature individuals are estimated to remain in the wild. Conservation measures are urgently needed to prevent extinction. IUCN Red List
Under which genus is the red crested tree rat currently classified?
Proechimys
Echimys
Isothrix
Santamartamys
The red crested tree rat is placed in the monotypic genus Santamartamys. It was previously confused with other Echimyidae genera, but molecular studies confirmed its distinct lineage. Its genus name honors the Sierra Nevada de Santa Marta region. Journal of Mammalogy
What is a major threat driving the decline of the red crested tree rat?
Deforestation and habitat fragmentation
Commercial trapping for fur
Invasive pathogens
Climate cooling
Deforestation for agriculture and logging in the Sierra Nevada de Santa Marta has destroyed much of the red crested tree rat's cloud forest habitat. Fragmentation isolates populations and reduces genetic diversity. Conservation plans focus on habitat protection and restoration. IUCN Red List
Which institution led the research team that rediscovered the red crested tree rat in 2011?
Alexander von Humboldt Biological Resources Research Institute
Colombian Ministry of Environment
Smithsonian Institution
World Wildlife Fund
Researchers from the Alexander von Humboldt Biological Resources Research Institute led the 2011 expedition that confirmed the red crested tree rat's existence. Their work involved mist-netting and camera trapping in remote cloud forests. The discovery was published in a peer-reviewed journal later that year. Instituto Humboldt
What is the dental formula of the red crested tree rat?
1.0.1.3/1.0.1.3
1.0.0.3/1.0.0.3
1.0.0.2/1.0.0.2
0.0.0.3/0.0.0.3
The red crested tree rat has the rodent-typical dental formula of 1.0.0.3/1.0.0.3, giving a total of 20 teeth. This formula reflects one pair of incisors and three pairs of molars in each jaw. No canines or premolars are present, as is common in Echimyidae. Journal of Mammalogy

Cheat Sheet

  1. Taxonomic Profile & Classification -

    The red crested tree rat, Santamartamys rufodorsalis, belongs to Kingdom Animalia, Phylum Chordata, Class Mammalia, Order Rodentia, and Family Echimyidae. Use the mnemonic "King Philip Catches Other Fine Great Snails" (KPCOFGS) to recall taxonomic ranks easily. This genus was clarified in the 2011 reclassification in the Journal of Mammalian Evolution.

  2. Specialized Cloud Forest Habitat -

    Restricted to the Sierra Nevada de Santa Marta cloud forests in Colombia at elevations of 2,000 - 2,500 meters, red crested rats rely on high-humidity canopies and bromeliad-rich trees. Studies from the Colombian Institute of Natural Sciences highlight that canopy fragmentation threatens their microhabitat niches. Remember "High Rain = Happy Rats" to associate elevation, humidity, and species persistence.

  3. Nocturnal Arboreal Adaptations -

    This elusive rodent is strictly nocturnal and arboreal, using its long prehensile tail and curved claws to navigate the canopy at night. Analogous to tree squirrels, it exhibits strong grasping abilities - critical for foraging and predator evasion. A simple mnemonic, "Nocturnal Red Rascals Are Amazing" (NRRAA), helps recall its nocturnal and arboreal traits.

  4. Omnivorous Diet & Ecological Role -

    Feeding on seeds, fruits, leaves, and insects, the red crested tree rat is a key seed disperser in cloud forests, promoting plant diversity. Research in the Journal of Tropical Ecology documents its role in regenerating endangered tree species by caching seeds. Think "Seed, Fruit, Insect, Repeat" to remember its varied diet and ecosystem services.

  5. Conservation Status & Threats -

    Classified as Endangered on the IUCN Red List due to habitat loss, agricultural expansion, and limited distribution. Conservationists use the acronym "HELP" (Habitat loss, Encroachment, Low numbers, Predation) to outline the four main threat categories. Ongoing habitat restoration programs in Colombia aim to protect remaining populations.
