Caribena versicolor, known as the Martinique Pinktoe tarantula, is endemic to the tropical rainforest within Martinique, Caribbean. The species have beautiful colorations of blue, red, and pink shimmering across the robust body with a dark treetrunk pattern on the abdomen and a metallic-green carapace. The spider will throughout its early development and growth possess its bright blue coloration with a touch of metallic shimmers. This coloration will last until the last molt before becoming adult and changing appearance towards its final appearance.

Natural Environment

Martinique and Guadeloupe are two islands in the Caribbean Sea that form the great island arc of the Antilles. Both islands have large and dense rainforests, but the northern parts of Martinique are the last primary rainforest of the Caribbean. There you will find extraordinary wildlife, featuring both flora and fauna with rich varieties of plants, flowers, animals, and of course the Caribena versicolor. As an arboreal species, they are often found in hollow branches, tree trunks, or tree crevices, and when the spider has found a perfect retreat/hide they create thick tube-like pathways by webbing the surrounding area which is commonly known for the species. Their natural climate has a wet season all year with close to no dry seasons. These humid forests can reach temperatures up to 29 - 32℃ (84 - 90℉). 

Behavior

Caribena versicolor is usually quite docile, however, if provoked they are commonly known for attempting to flee. But if they feel cornered and agitated they use their urticating hairs. But overall behavior is calm and often visible in the enclosure, as they spend most of the time in the tub-like webs. Spiderlings are often seen close to the ground as they search for terrestrial prey items. This behavior fades away as they mature and with time slowly traverse higher up. Another fascinating aspect of this species is that they are prone to jump when given the opportunity. Younger specimens tend to leap more rather than adult spiders, however, they still possess the ability and can still do it.

Enclosure/Terrarium

Terrarium: arboreal species require more vertical space with a minimum of 20x20x40 for an adult specimen. As long as the terrarium can hold the specimens 2.5x span width in height which is also applied for spiderlings. 

Substrate: a layer of rocks, or clay aggregate (LECA), covered with a thin net to prevent the soil from reaching the first layer of coconut fiber. Cover the first layer with coconut fiber or a substrate mix suitable for tarantulas. By doing this, you allow air to circulate the substrate to prevent the possibility of mold or fungi. The amount of substrate, and thickness, should be about the same as the length of the spider. 

Plants: depending on the humidity requirements, plants are a great resource as they preserve moisture in the soil, as well as possible hiding opportunities for the spider. Plants are also great decor for your terrariums, bringing some colors and making the enclosure look alive—recommended plants: Philodendrons, Bromeliads, Epipremnum aurerum, Ferns, Moss, Tillandsia, or Ficus pumila.
