Heterophrynus batesii
One of the world's largest whip spiders, from the western Amazon rainforest. An adult male's pedipalps span about 20cm when unfolded, said to be the longest of any arachnid. Venomless but delicate and hard to source, it suits experienced keepers.
Heterophrynus batesii is a phrynid whip spider of the Amazon rainforest in Colombia, Ecuador, Peru, Brazil and Bolivia, one of the 17 species of Heterophrynus, placed in the monotypic subfamily Heterophryninae. An adult male's pedipalps reach about 20cm unfolded, said to be the longest of any arachnid, and the antenniform first legs are far longer still, giving this species and a close relative the greatest span of any arachnid. Animals usually enter the trade at around the third instar, already as large as adults of other species. They are sensitive to change and transport, and specialist suppliers refuse to ship them where temperatures fall below freezing. Moulting needs several times the body's length in clear space; without enough room away from the vertical surface, moults fail.

Keep it within the general amblypygid guideline (23-26 C and 75-85% humidity, as for Damon medius). It is intolerant of cold, including during transport.
The span is enormous, so the enclosure needs generous height and width. Stand cork bark to give broad vertical surfaces and leave clear space for moulting.
Crickets and red runner roaches. Even juveniles are large, so match prey size accordingly.
Venomless and silkless. Shy, darting sideways when startled. The large spiny pedipalps can give a thorn-like puncture if they grip a finger.
Hard to source and sensitive to change. Moults fail easily, so leave ample clearance between the vertical surface and the floor.
Advanced. This is an advanced-level species. It requires specialized equipment and advanced husbandry skills with precise environmental control.
The ideal temperature for Giant Amazon Whip Spider is 23〜26℃. Recommended humidity is 75〜85%. Avoid sudden temperature changes and maintain a stable environment.
The average lifespan of Giant Amazon Whip Spider is 5-8 years. With proper care and nutrition, they can live a long and healthy life.
Giant Amazon Whip Spider typically reaches Pedipalps up to about 20cm unfolded, with far longer whip-like first legs as an adult. Size may vary depending on care conditions and individual genetics.
Giant Amazon Whip Spider feeds on: Insects such as crickets and red runner roaches. Aim for a balanced diet with appropriate feeding frequency.
