Tapirus terrestrisBrazilian tapir(Also: South American tapir)

Ge­o­graphic Range

Tapirus ter­restris can be found pre­dom­i­nantly in Brazil, but its range cov­ers much of South Amer­ica’s trop­i­cal forests. It ranges from north­ern Ar­gentina to Venezuela, but is ab­sent from Chile and lo­ca­tions west of the An­dean Cordillera. (Eisen­berg and Hub­bard Red­ford, 1999; Nor­ton and Ash­ley, 2004; Nowak, 1999; Padilla and Dowler, 1994; Wil­son and Reeder, 2005)

Habi­tat

Brazil­ian tapirs pre­fer trop­i­cal mon­tane forests, but are also pre­sent in swamps and low­land forests. It can be found from sea level up to 4500 me­ters in el­e­va­tion. They are adept moun­tain climbers and some­times cre­ate paths to larger bod­ies of water. They pre­fer to live close to water, es­pe­cially rivers, and are com­fort­able swim­mers. The high­est pop­u­la­tion den­si­ties are found in areas with lush veg­e­ta­tion and 2,000 to 4,000 mm of rain­fall per year. (Eisen­berg and Hub­bard Red­ford, 1999; Hus­son, 1978; Padilla and Dowler, 1994)

Phys­i­cal De­scrip­tion

Adult mass of Brazil­ian tapirs ranges from 150 to 250 kg. Shoul­der height varies from 77 cm to 108 cm, while body length can reach 221 cm in fe­males and 204 cm in males. Their skulls have a promi­nent sagit­tal crest that gives the top of the head a hump­like pro­jec­tion ex­tend­ing from the eyes to the neck, and a short mane fol­lows the sagit­tal crest pro­jec­tion. Adults are dark brown to red, and ju­ve­niles are brown with hor­i­zon­tal white stripes, which fade after seven months. Brazil­ian tapirs have hooves and a pro­nounced pro­boscis. The pro­boscis is made up en­tirely of soft tis­sue, and the snout has sig­nif­i­cantly re­duced bone and car­ti­lage com­pared to other un­gu­lates. The mo­lars are lophodont, and the den­tal for­mula is 3/3, 1/1, 4/3, 3/3 = 42. (Eisen­berg and Hub­bard Red­ford, 1999; Nowak, 1999; Padilla and Dowler, 1994; Wit­mer, et al., 1999; Zo­o­log­i­cal So­ci­ety of Lon­don, 1867)

Re­pro­duc­tion

The mat­ing sys­tem of Tapirus ter­restris has not yet been de­ter­mined. When fe­males are sex­u­ally re­cep­tive, males com­pete for the right to mate by bit­ing one an­other on the feet, sug­gest­ing polyg­yny. (Eisen­berg and Hub­bard Red­ford, 1999; Padilla and Dowler, 1994)

Ges­ta­tion in Brazil­ian tapirs typ­i­cally lasts for 380 days, but ranges from 335 to 439 days. Es­trous oc­curs every 50 to 80 days and lasts for 48 hours. Most fe­males be­come sex­u­ally ma­ture be­tween 2 and 3 years of age. The old­est fe­male recorded to have given birth in cap­tiv­ity was 28 years old. Brazil­ian tapirs breed year round. They have 1 off­spring at a time, which weighs from 3.2 to 5.8 kg at birth. Wean­ing is com­plete by 6 to 8 months of age, and most off­spring are in­de­pen­dent by 18 months of age. (Eisen­berg and Hub­bard Red­ford, 1999; Nowak, 1999; Padilla and Dowler, 1994)

Fe­male Brazil­ian tapirs nurse young for 6 to 10 months and con­tinue to live with young for an ad­di­tional 1 to 8 months. Males pro­vide no parental care to off­spring. (Eisen­berg and Hub­bard Red­ford, 1999; Nowak, 1999; Padilla and Dowler, 1994)

Lifes­pan/Longevity

There is lit­tle in­for­ma­tion avail­able con­cern­ing the lifes­pan of Tapirus ter­restris. Typ­i­cally, it lives for 35 years in cap­tiv­ity, and there is no in­for­ma­tion re­gard­ing the lifes­pan of wild in­di­vid­u­als. (Padilla and Dowler, 1994)

Be­hav­ior

Brazil­ian tapirs are typ­i­cally soli­tary, and al­though they are not ex­clu­sively noc­tur­nal, they tend to keep to the shel­ter of the for­est dur­ing the day and come out to feed at night. They are often seen in pairs dur­ing mat­ing sea­son and when fe­males travel with off­spring. Brazil­ian tapirs have lim­ited eye­sight, but strong ol­fac­tory per­cep­tion. Al­though they are usu­ally shy, they are ag­gres­sive while com­pet­ing for mates or de­fend­ing ter­ri­to­ries. (Eisen­berg and Hub­bard Red­ford, 1999; Padilla and Dowler, 1994; Wil­son and Reeder, 2005)

Home Range

There is no in­for­ma­tion avail­able re­gard­ing the home ranges of Brazil­ian tapirs.

Com­mu­ni­ca­tion and Per­cep­tion

Brazil­ian tapirs pro­duce sev­eral vo­cal­iza­tions. A shriek­ing sound is used to ex­press fear, dis­tress, or pain. Click­ing noises may be used to iden­tify them­selves to con­specifics, par­tic­u­larly dur­ing mat­ing sea­son. They show ag­gres­sion with a nasal snort, and when ir­ri­tated, it makes a puff­ing noise. Brazil­ian tapirs also use meth­ods of chem­i­cal com­mu­ni­ca­tion, as they uri­nate and use fa­cial glands to de­mar­cate ter­ri­to­r­ial bound­aries. (Hun­saker and Hahn, 1965; Padilla and Dowler, 1994)

Food Habits

Brazil­ian tapirs browse at night, eat­ing fruit, leaves, and other plant ma­te­r­ial. Pre­ferred for­age plants in­clude mom­bins, which pro­duces fruit sim­i­lar to large plums; huito, which pro­duces large berry-like fruit; and moriche palm, which pro­duces palm fruit. (Nowak, 1999)

  • Plant Foods
  • leaves
  • wood, bark, or stems
  • seeds, grains, and nuts
  • fruit

Pre­da­tion

Other than hu­mans, the tapir’s main preda­tor is the jaguar. They are some­times taken by croc­o­dylians. When alarmed by preda­tors, tapirs flee to water or the near­est brush. If cor­nered, how­ever, a tapir runs di­rectly at its preda­tor. Its semi-noc­tur­nal ten­den­cies may help de­crease risk of pre­da­tion. (Padilla and Dowler, 1994)

Ecosys­tem Roles

Brazil­ian tapirs are browsers and graz­ers. They are ex­cep­tion­ally com­mon in cer­tain area of their ge­o­graphic range and make up a sig­nif­i­cant por­tion of the total bio­mass in these com­mu­ni­ties. They are fru­giv­o­rous and are po­ten­tial seed dis­persers of many im­por­tant fruit trees through­out their ge­o­graphic range. Their di­ges­tion gen­er­ally leaves in­gested seeds un­dam­aged, as is the case with fruit from assai palms and epena. Brazil­ian tapirs are host to a num­ber of par­a­sites in­clud­ing sev­eral species of ticks (Haemo­physalis jux­takochi and Am­bly­omma ovale), nu­mer­ous species of cil­i­ated pro­to­zoa (Buisonella tapiri, Ble­pharo­co­rys car­dionu­cle­ata, Bal­an­tid­ium coli, and Pro­to­tapirella in­testi­nalis), and round­worms (Neo­mur­shidia mono­stichia and Physocepha­las ni­tidu­lans). Bur­row­ing mites some­times cause sar­cop­tic mange. (Eisen­berg and Hub­bard Red­ford, 1999; Padilla and Dowler, 1994)

Eco­nomic Im­por­tance for Hu­mans: Pos­i­tive

Brazil­ian tapirs are hunted for hide and meat, pro­vid­ing a sig­nif­i­cant amount of pro­tein to the diets of var­i­ous rural pop­u­la­tions. They have been do­mes­ti­cated in Brazil and taught to pull plows and allow chil­dren to ride them. They are also kept in nu­mer­ous zoos across the globe. (Padilla and Dowler, 1994)

  • Positive Impacts
  • food
  • body parts are source of valuable material

Eco­nomic Im­por­tance for Hu­mans: Neg­a­tive

There are no known ad­verse ef­fects of Tapirus ter­restris on hu­mans.

Con­ser­va­tion Sta­tus

Tapirus ter­restris is clas­si­fied as Vul­ner­a­ble by the IUCN's Red List of Threat­ened Species. Al­though more stud­ies are needed to de­ter­mine cur­rent pop­u­la­tion den­si­ties and trends, it is widely thought that T. ter­restris is de­clin­ing through­out its ge­o­graphic range. Major threats in­clude over hunt­ing, com­pe­ti­tion with live­stock, and habi­tat loss through de­for­esta­tion. It oc­curs in nu­mer­ous pro­tected areas through­out its range, and al­though it is legally pro­tected from hunt­ing, these laws are rarely en­forced and have proven in­ef­fec­tive. The Con­ven­tion on In­ter­na­tional Trade in En­dan­gered Species of Wild Fauna and Flora (CITES) lists T. ter­restris under Ap­pen­dix II, and the species is listed as En­dan­gered by the United States Fish & Wildlife Ser­vice.

Glossary

Neotropical

living in the southern part of the New World. In other words, Central and South America.

World Map

chemical

uses smells or other chemicals to communicate

endothermic

animals that use metabolically generated heat to regulate body temperature independently of ambient temperature. Endothermy is a synapomorphy of the Mammalia, although it may have arisen in a (now extinct) synapsid ancestor; the fossil record does not distinguish these possibilities. Convergent in birds.
