Caribena versicolor

Antilles pinktoe tarantula

An arboreal tarantula endemic to Martinique, famous for changing from electric blue as a juvenile to a layered green, magenta, and red adult palette. These photographs come from my former collection.

In the wild

Natural history.

Habitat & lifestyle

An arboreal Martinique endemic. It constructs silk retreats in elevated cavities and among vegetation rather than living as a ground-level burrower.

What to notice

Ontogenetic colour change is dramatic: vivid blue juveniles mature into green, purple, magenta, and red adults with pink-tipped feet.

Archive status

The image is mine and the animal was once in my care. It is not a current resident; the profile is a species resource, not a live collection record.

Taxonomy and range

The World Spider Catalog recognises Caribena versicolor (Walckenaer, 1837) as an accepted species endemic to Martinique. It was long known as Avicularia versicolor and was transferred to the newly established genus Caribena in a major 2017 revision.

Retreats, shelter, and activity

Field records place the species mainly in mesophyll forest. Individuals build silken retreats among bromeliad leaves and on branches, bamboo, tree trunks, and occasionally human structures—microhabitats that provide height, anchoring points, and a protected tube.

Feeding ecology

It is an opportunistic sit-and-wait predator of small animals encountered on vegetation. The retreat acts as both shelter and a sensory structure, carrying vibrations that help the spider detect movement nearby.

A name preserved in the photo archive

These photographs were filed under the older name Avicularia versicolor. Keeping that history visible is useful: scientific names can change as new evidence reshapes relationships, while the animal and the observation remain the same.

Conservation context

Status, trade & uncertainty.

IUCN and CITES answer different questions. The cards below keep extinction-risk assessment, trade controls, evidence quality, and responsible keeping separate.

IUCN Red List

Not Evaluated

No species-level assessment was located in IUCN Red List version 2026-1. That is a gap in formal assessment, not evidence that the wild population is secure.

International trade

CITES Appendix III

Caribena versicolor is included in Appendix III by the European Union. International transactions should be checked against the live listing and the rules that apply in each country.

Evidence in context

A Martinique endemic

The entire native range is concentrated on one island. Published field records associate the species with mesophyll forest and elevated retreats, but a reliable global population trend is not available.

For keepers

Keep the paper trail

Prefer documented captive-bred animals and retain breeder or seller details, receipts, dates, and the scientific name. Older Avicularia versicolor records should remain linked to the current name.

Reviewed 14 September 2026 against IUCN Red List version 2026-1 and the live CITES checklist. “Not Evaluated” describes an assessment gap; it is not a low-risk category.
