Origin And Natural Habitat
The Tapajós region of Brazil — specifically the lowland rainforest along the Tapajós River in the Tapajós National Forest in the state of Pará — is the confirmed home of Bumba tapajos. This is one of the Amazon’s most significant river systems, flowing north through central Brazil before joining the Amazon River near Santarém, and the forest along its banks represents some of the most biodiverse and ecologically intact lowland Amazon rainforest remaining in Brazil. Average annual rainfall at the type locality is 1,820 millimetres, with temperatures ranging from 21 to 31°C — consistently warm, continuously humid lowland tropical rainforest conditions that sustain one of the richest ecosystems on Earth. The forest along the Tapajós river banks sits at approximately 100 metres above sea level, with the terrain rising slightly to the Tapajós-Xingu plateau at 120 to 170 metres further from the river.
As a terrestrial fossorial species living in the rich, moist soils of this rainforest, B. tapajos constructs and occupies burrows in the Amazon forest floor — the same fossorial lifestyle shared with its close relative the Brazilian Redhead (B. horrida), applied in an environment of even higher rainfall and more consistently humid conditions than the more seasonal Amazon habitats further south. The species is a fantastic burrower that will reconstruct its enclosure to its liking given appropriate substrate depth — a quality that makes the enclosure design choices around substrate depth more important than any other single element of care.
An important note on naming: the hobby circulates this species under both Bumba tapajos and Bumba cf. tapajos — the cf. designation indicating some uncertainty about whether all specimens in captivity represent the formally described species or a closely related form from the same region. The formal description from Lucas, Passanha, and Brescovit in 2020 is the scientific anchor, and both names in the hobby refer to the same vivid pink-headed Brazilian tarantula.
Scientific Classification
Formally described by Lucas, Passanha, and Brescovit in 2020, Bumba tapajos is one of the most recently described tarantula species to have entered the hobby with any meaningful keeper following — the speed at which it went from formal description to available captive-bred specimens reflecting both the high collector demand its appearance generated and the practical challenge that Brazil’s strict wildlife exportation ban creates for sourcing. The species name tapajos directly honours the Tapajós region and river of the type locality — a straightforward geographic naming consistent with the Bumba genus tradition of locality-based names. The World Spider Catalog confirms B. tapajos Lucas, Passanha & Brescovit, 2020 as the current valid name. Full classification: Kingdom Animalia, Phylum Arthropoda, Class Arachnida, Order Araneae, Infraorder Mygalomorphae, Family Theraphosidae, Genus Bumba, Species B. tapajos Lucas, Passanha & Brescovit, 2020.
Species Overview
The most immediate way to understand Bumba tapajos in the hobby context is as the Brazilian Redhead taken to a higher level of visual intensity. Where B. horrida carries a deep crimson-red carapace against a jet-black body, B. tapajos carries a blindingly bright metallic pink-red carapace that is so saturated it genuinely looks synthetic — almost as if the colour was applied rather than evolved. This escalation in colour intensity, combined with the same beginner-friendly temperament profile of the Bumba genus, has made it one of the most sought-after new species in the hobby since its description. The challenge is sourcing — Brazil’s strict wildlife exportation ban means no new specimens can legally be brought into the hobby, making every captive-bred specimen from US and European breeders genuinely significant for maintaining the hobby population of this recently described species.
Appearance And Size
The carapace is the entire visual story of this species and it deserves careful description. The metallic pink-red carapace against the velvety black body and legs creates a contrast so intense that photographs routinely look colour-corrected even when they are not. The pink quality is more vivid and more metallic than the deep crimson-red of B. horrida — where the Brazilian Redhead’s carapace has a warm, saturated red quality, the Tapajos Pink Head’s carapace has a bright, almost iridescent pink-red metallic sheen that catches the light differently as the spider moves. The formal description from the type specimen — cephalothorax and legs red brown, abdomen dorsally black and ventrally grayish — was made from specimens preserved in ethanol, and the living animal’s colouration in captive keeper photographs is far more vivid than this preserved description suggests. The legs carry the same velvety black quality as B. horrida, and the contrast between the metallic pink carapace and the matte black body is one of the more dramatic colour contrasts in any terrestrial tarantula available in the hobby.
Adult size reaches approximately 5 inches — slightly larger than B. horrida according to most keeper documentation. The exact lifespan is not established from captive records given the species’ extremely recent formal description, but based on B. horrida‘s documented 12 to 15 year female lifespan a similar range is a reasonable working estimate.
Housing
A terrestrial enclosure with floor space and substrate depth as joint priorities. A footprint of 20 by 20 to 25 by 25 centimetres suits adult females at 5 inches legspan, with 4 to 5 inches of substrate and height kept to twice the legspan maximum. The burrowing character of the genus is strong — slings can be housed in a simple deli cup with adequate substrate, while adults need a proper terrestrial enclosure with sufficient depth for the burrow construction that defines this genus’s lifestyle. A latching lid is standard. Our best tarantula enclosure guide covers terrestrial formats appropriate for medium to large Amazonian Brazilian fossorial species, and our best tarantula sling enclosure guide covers the smaller containers appropriate for early juvenile stages.
Enclosure’s Decorations
A pre-formed starter burrow angled into the substrate gives the spider an immediate starting point, with the understanding that the spider will likely rearrange the substrate to its preference once established — a species described as reconstructing its enclosure to its liking. Cork bark or additional surface decoration gives retreat options for the above-ground periods. A shallow water dish at the opposite end provides hydration access. Our best tarantula hide and best tarantula cork bark guides cover appropriate pieces for Amazonian fossorial terrestrial species.
Substrate
Four to five inches of moisture-retaining substrate with good structural integrity for burrow construction. ABG mix, coconut coir, and organic soil blends all work well — the priority is a substrate that holds burrow shape and retains appropriate moisture through its depth without becoming waterlogged at the surface. The 1,820mm annual rainfall of the Tapajós National Forest habitat means consistently moist substrate conditions are appropriate — more moisture-retaining than the seasonally drier conditions of B. horrida‘s range. Our best tarantula substrate guide covers moisture-retaining blends appropriate for continuously humid Amazonian lowland terrestrial species.
Water And Humidity
A shallow water dish at all times, refreshed every two to three days. Moderate humidity with proper ventilation is the consistent care recommendation — 65 to 75 percent ambient, achieved through a lightly damp substrate section and water dish evaporation rather than mechanical humidification. The high annual rainfall of the Tapajós lowlands means this species requires more consistent moisture than drier-habitat relatives, but proper ventilation remains essential to prevent the stagnant air that harms all tarantulas regardless of humidity requirements. A hygrometer confirms actual conditions, and a misting bottle handles targeted moisture additions to the substrate sides without surface saturation.
Heating And Temperature
The Tapajós National Forest maintains temperatures between 21 and 31°C year-round — a warm tropical range with the coolest period in June and July and the warmest period from September through November. A captive range of 72 to 82°F suits this species well. Most temperate indoor environments are appropriate without supplemental heat for much of the year. A side-mounted heat mat controlled by a thermostat handles periods when ambient temperatures drop consistently below 70°F. A thermometer at substrate level confirms actual enclosure conditions rather than ambient room readings.
Diet And Nutrition
Crickets, dubia roaches, and other appropriately sized invertebrates weekly for adults, with juveniles every five to seven days. The species is described as a slow grower relative to some Amazonian species — consistent feeding through the juvenile phase supports development without the overfeeding risk that a very slow-growing species with a robust appetite creates. Remove uneaten prey within 24 hours. Our best tarantula food guide covers feeder options and sizing for medium-sized Amazonian lowland fossorial species.
Compatibility
Solitary only. Given Brazil’s strict wildlife exportation ban meaning no new legal imports can supplement captive populations, every successful captive breeding pairing is genuinely significant for maintaining hobby access to this recently described species. A well-fed female and supervised introduction are essential.
Behavior And Temperament
Calm, slow-moving, and confident describes the adult temperament consistently across keeper accounts — the same gentle Bumba disposition that makes its close relative the Brazilian Redhead so approachable, present in full in this more visually dramatic relative. One keeper describes the personality as a perfect choice for both novice and experienced keepers — the combination of handleable temperament and extraordinary adult display colouration making it rewarding at every experience level. Urticating hairs are present as the standard New World defensive tool. The shift from reclusive sling to visible, open-display adult is documented for this species as for B. horrida, making the adult keeper experience significantly more visually engaging than the juvenile phase.
Handling
Described as very handleable for a confident, calm species whose adult temperament makes it one of the more manageable medium-sized South American terrestrials available. Standard floor-level protocol with slow movements. The metallic pink carapace at close range is one of the more visually striking handling experiences available in the hobby’s Amazonian species, and the contrast between the pink head and black legs is even more dramatic at close quarters than through enclosure glass. Venom is medically insignificant to healthy humans.
Health And Lifespan
Precise lifespan data is not yet established from captive records given the species was only described in 2020 and the captive history is extremely short. Based on the close relationship to B. horrida and the comparable adult size, females likely live 10 to 15 or more years. The species is described as hardy within appropriate warm, moderately humid Amazonian conditions. Primary health considerations are adequate substrate depth for the burrowing behaviour, appropriate moisture management, and the warm temperatures of the lowland Amazon habitat. Our tarantula dehydration article covers identification and recovery for dehydration concerns in continuously humid Amazonian lowland species.
Price
Genuinely rare in captive-bred form given Brazil’s exportation ban making new imports impossible and the very short captive history since the 2020 description. Westside Tarantulas has produced US captive-bred batches and describes them as among only a few produced in the USA. Urban Tarantulas lists slings from $76 USD. Slings typically sell for $60 to $120 USD when available from reputable captive breeders. Juveniles range from $100 to $200. Confirmed adult females, being extraordinarily rare at this stage of the species’ captive history, command $200 to $400 or more. Source captive-bred specimens only without exception — Brazil’s exportation ban makes wild-caught specimens both illegal and ethically unjustifiable, and supporting the small number of breeders working to establish this species in captivity is the only responsible approach.
