“A rose by any other name would smell as sweet” – William Shakespeare
It was talked about and anticipated for years, and on April 26, it became official. Jorge Mendoza and Oscar Francke’s paper on the revision of the Brachypelma red-kneed tarantulas was officially published. This paper had many informed hobbyists sighing in resignation as they reached for their label makers and bade farewell to a familiar name. As a result, the beloved Brachypelma smithi that has proliferated collections for decades has a brand new name…Brachypelma hamorii.

An impaction occurs when the tarantula’s anus becomes obstructed, rendering it unable to defecate. The spider will often continue to eat and drink normally, giving the keeper little indication that something is amiss even as the waste builds up inside it.
