Mexican Pink Beauty Tarantula (Brachypelma klaasi)

Brachypelma klaasi

The Brachypelma klaasi, known as 'Mexican Pink Beauty Tarantula'. It is one of the rarest, darkest and most thickly hairy Brachypelma, famous (5.5-6.3 inches legspan) for the incredible pink/copper or burgundy coloration of the very long hairs that cover the legs and abdomen, in stark contrast with the velvety black body. While maintaining the burrowing nature, it is considered one of the most docile and tolerant Brachypelma, albeit subject to the same CITES protections and the very slow growth rates of its genus.
