Description de l'espèce
Geographical Origin and Habitat: Native to the warm, humid tropical rainforests of Venezuela and Guyana. It is strictly arboreal, nesting in hollow trees, vertical bark crevices, or large epiphytes, where it constructs retreats camouflaged with silk, soil, and bark debris.
Taxonomy and Genetics: Adult females are highly striking, reaching a leg span of 14-16 cm, with a deep velvety black coloration, bright orange chevron patterns on the abdomen, and orange-tipped legs. Males are smaller, lighter greyish-brown, and lose their vibrant colors after their mature molt. This species lacks urticating hairs.
Behavior and Habits: Strictly nocturnal and arboreal. Highly active and lightning-fast. It is a reclusive spider that spends the day in its vertical silk tube, emerging at night to hunt. It is highly defensive; when disturbed, it will readily assume a threat pose and strike repeatedly if cornered.
Morphology: Distinct sexual dimorphism. Mature females are much larger, heavier, and display intense black and orange coloration. Males are smaller, thin, lack the orange coloration, and possess longer legs.
Soins, reproduction et cohabitation
Terrarium Setup: Requires a vertically oriented enclosure (minimum 20x20x40 cm). Furnish with tall, hollow cork bark tubes or slabs placed vertically. Provide a moisture-retaining substrate such as coco fiber or peat (7-10 cm deep) and a shallow elevated water dish.
Lighting and Heating: Maintain a warm environment with daytime temperatures of 25-28°C and a night drop to 20-22°C. Avoid direct heat lamps or bright lights, as this species is highly photophobic.
Humidity and Hydration: Requires high relative humidity (70-85%). Dampen the substrate regularly while ensuring excellent cross-ventilation to prevent stagnant air, which can cause fatal fungal infections or respiratory issues.
Feeding and Supplementation: Voracious hunter. Feeds on grills, roaches, and locusts. Adult spiders should be fed once every 10-14 days. Remove any uneaten prey or food remains to maintain cleanliness.
Compatibility: Strictly solitary and territorial. Due to high cannibalistic tendencies, they must be housed individually. Cohabitation with other species is not possible.
Health and Common Diseases: Vulnerable to dehydration, mold, and poor ventilation. Due to their active nature, falls can cause fatal abdominal rupture. The venom is medically significant, causing severe pain and muscle cramping; handling is strictly prohibited.

Profil d'invertébré terrestre
- Régime alimentaire
- Insectivore
- They are aggressive eaters with an explosive feeding response. They eagerly accept crickets, roaches, and occasional mealworms. They will leap from their hides to snatch prey with incredible speed. Because they are arboreal, it is best to offer prey that can climb near the entrance of their web to ensure they find it.
- Taille adulte
- 15 cm
- Mode de vie/microhabitat
- Arboreal
- This species leads a highly arboreal lifestyle, though spiderlings often exhibit fossorial tendencies by burrowing at the base of trees. As they mature, they construct elaborate silken retreats high up in vertical cork bark tubes, often incorporating dirt and debris into the webbing for camouflage. They require tall enclosures with high humidity.
- Cycle d'activité
- Nocturnal
- The Venezuelan Suntiger is predominantly nocturnal, hiding within its arboreal silken tube during the day. As night falls, it becomes an extremely active and agile hunter, leaving its retreat to patrol the bark of trees in search of insects, relying on speed and vibration sensitivity to ambush its prey.
- Sociabilité
- Solitary
- The Venezuelan Suntiger is strictly solitary. They are highly territorial and aggressive toward other spiders. Any attempt to house them communally will invariably lead to violent clashes and cannibalism. They must be kept entirely separated from the time they are young spiderlings to ensure their survival.
- Reproduction
- Oviparous
- Breeding can be successful, but females are known to be aggressive toward males. If mating is successful, the female will weave a silken egg sac within her arboreal tube. Uniquely, females of this genus are sometimes known to produce a second, smaller egg sac ("double clutching") months later from a single mating.
- Venimeux
- Yes
- Tolérance aux manipulations
- With caution
- Handling should never be attempted. While they are New World tarantulas, they lack urticating hairs and make up for it with an incredibly defensive attitude, lightning-fast speed, and a tendency to jump unpredictably. When disturbed, they are more likely to deliver a rapid, painful bite than try to escape.
- Brumation
- Non requise
- Originating from the tropical regions of Venezuela, they do not require brumation. They thrive in consistently warm, humid environments year-round. It is vital to provide excellent cross-ventilation, as stagnant, swampy conditions will quickly lead to respiratory failure or fungal infections, proving fatal to the spider.
- Mue
- Periodic
- Molting takes place within the confines of their arboreal silken retreat. They will construct a hammock-like structure inside the tube and molt on their backs. High humidity is essential during this period. Live prey must be removed, and the spider should remain completely undisturbed until its fangs are fully hardened.
