Bahia hairy dwarf porcupines use their quills to deter predators. The quills are barbed, making them painful and potentially dangerous when they enter the flesh of a predator. Predators include snakes, raptors, cats, and humans.
Known Predators:
Bahia hairy dwarf porcupines are small porcupines, from 1.2 to 1.5 kg and 70 cm from tail to nose. The tail is prehensile, which allows greater stability in trees. Individually barbed quills and soft hair protect them from predators. All white variants of this species are sometimes observed.
Range mass: 1.2 to 1.5 kg.
Range length: 60 to 80 cm.
Other Physical Features: endothermic ; homoiothermic; bilateral symmetry ; polymorphic
Sexual Dimorphism: sexes alike
There is little information on longevity in S. insidiosus. Bahia hairy dwarf porcupines are expected to live to around 15 years in the wild before natural causes or predation limits their life.
Average lifespan
Status: wild: 15 years.
Average lifespan
Status: captivity: 21 years.
The Caatinga region of Brazil receives powerful winds from each direction which influences rainfall. The climate is hot and arid, with a summer rainfall pattern. Caatinga consists of a mosaic of vegetation communities, from cerrado (savanna) to humid montane forest in high areas.
Range elevation: 0 to 1000 m.
Average depth: 0 m.
Habitat Regions: tropical ; terrestrial
Terrestrial Biomes: savanna or grassland ; forest
Sphiggurus insidiosus can be found in evergreen forests in the Caatinga region of Brazil. This region extends from northeastern to east-central Brazil, where it is bordered by semi-arid desert.
Biogeographic Regions: neotropical (Native )
Bahia hairy dwarf porcupines are mainly herbivorous, although they will also eat ant pupae. They eat mostly fruit, seeds, roots, and bark while foraging at night.
Animal Foods: insects
Plant Foods: leaves; roots and tubers; wood, bark, or stems; seeds, grains, and nuts; fruit; flowers
Primary Diet: herbivore (Folivore , Lignivore)
Bahia hairy dwarf porcupines benefit many plants by eating and dispersing their seeds. They also negatively affect some tree species by eating the roots and bark of trees, causing them to die. Some ant species are also preyed on by S. insidiosus. They destroy ant communities by eating the pupae and digging through the nests.
Ecosystem Impact: disperses seeds
Bahia hairy dwarf porcupines are usually quiet, except during the mating season when they use a series of whines, grunts, barks, and screams to attract mates. They also have vocalizations that they use between mothers and young. Like most mammals, it is likely that chemical cues are important in communicating.
Communication Channels: visual ; acoustic ; chemical
Perception Channels: visual ; tactile ; acoustic ; chemical
Bahia hairy dwarf porcupine populations are considered stable currently.
US Federal List: no special status
CITES: no special status
State of Michigan List: no special status
IUCN Red List of Threatened Species: least concern
There are no known adverse effects of S. insidiosus on humans.
Humans hunt Bahia hairy dwarf porcupines for their quills and meat. The quills may be used for artwork, weapons, or medical reasons.
Positive Impacts: food ; body parts are source of valuable material
The mating system for S. insidiosus is not well documented. Screaming, barking, and grunting are used to attract females in heat.
Female Bahia hairy dwarf porcupines are pregnant or lactating for much of their lives. They usually produce one precocial offspring with each pregnancy. The gestation period is about 200 days, with young reaching independence at about 8 to 12 weeks old. Males and females reach sexual maturity at 1.5 to 2.5 years of age.
Breeding interval: Bahia hairy dwarf porcupines breed once each year.
Breeding season: Bahia hairy dwarf porcupines breed throughout the year.
Range number of offspring: 1 to 1.
Average gestation period: 200 days.
Average weaning age: 0 minutes.
Range time to independence: 8 to 12 weeks.
Range age at sexual or reproductive maturity (female): 1.5 to 2.5 years.
Range age at sexual or reproductive maturity (male): 1.5 to 2.5 years.
Key Reproductive Features: iteroparous ; year-round breeding ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; viviparous
Parental care in Bahia hairy dwarf porcupines is rather short. The young are born with hair and quills, and capable of walking within the first few minutes of birth. The juvenile reaches independence within 8 to 12 weeks.
Parental Investment: precocial ; pre-fertilization (Provisioning, Protecting: Female); pre-hatching/birth (Provisioning: Female, Protecting: Female); pre-weaning/fledging (Provisioning: Female)
The Bahia porcupine (Coendou insidiosus), is a New World porcupine species in the family Erethizontidae endemic to the Atlantic Forest of southeastern Brazil.[2] It was formerly sometimes assigned to Sphiggurus,[2] a genus no longer recognized since genetic studies showed it to be polyphyletic.[3] Sphiggurus pallidus, formerly considered a separate species but known from two young specimens only, is a synonym of this species.[1]

Porc-épic laineux, Porc-épic des Antilles
Sphiggurus insidiosus est une espèce qui fait partie des rongeurs de la famille des Erethizontidae appelés porcs-épics préhensiles. Ces porcs-épics sont endémiques du Brésil. Ce sont des animaux terrestres nocturnes et arboricoles qui fréquentent essentiellement la canopée des forêts de la côte Atlantique. Cet animal végétarien à tendance omnivore se nourrit aussi bien de fruits que de pupes de fourmis. Il s'approche parfois des habitations pour y chaparder les légumes cultivés au potager[1]. En français, il est appelé Porc-épic laineux ou Porc-épic des Antilles[2].
Cette espèce a été décrite pour la première fois en 1818 par le naturaliste allemand Ignaz von Olfers (1793-1871).

Sphiggurus insidiosus[2] är en däggdjursart som först beskrevs av Lichtenstein[1] eller Olfers[2] 1818. Sphiggurus insidiosus ingår i släktet Sphiggurus och familjen trädpiggsvin.[3][4] IUCN kategoriserar arten globalt som livskraftig.[1] Inga underarter finns listade i Catalogue of Life.[3]
Enligt omstridda uppgifter fångades två ungdjur på västindiska öar. De listades tidvis som självständig art, Sphiggurus pallidus. Enligt nyare studier tillhör dessa exemplar arten Sphiggurus insidiosus.[1]
Detta trädpiggsvin förekommer i östra Brasilien från Amazonflodens mynning till delstaten São Paulo. Habitatet utgörs av olika slags skogar. Individerna vistas ganska ofta nära människans samhällen. De är aktiva på natten och klättrar främst i växtligheten. Sphiggurus insidiosus äter frukter, rötter, grönsaker och myrornas larver.[1]

Мешкає в Атлантичному прибережних районах східної Бразилії. Зустрічається в приатлантичному первинному лісі, але частіше у вторинному лісі й на межі лісу й безлісся. Деколи виявляється й поблизу міст.
Веде нічний і деревний спосіб життя; харчується плодами, личинками комах, культивованими овочами й корінням.
Не відомо, щоб на нього велося полювання. Жодних заходів щодо охорони даного виду не вживається, бо вважається, що зараз у цьому немає потреби.
