So far, research has concentrated peptide calcium and potassium channel antagonists from Grammostola spatulata venom that have useful selectivities. Recently, a novel antagonist of stretch-activated ion channels has also been characterized from the venom. A toxin from this venom has also been proposed as a substitute for morphine: Zeneca Unveils Money Spider. Our spiders were collected by anonymous collector(s) in Chile and shipped to importers in the United States, from whom we purchased the spiders. We do not have locality data as we do for our other species. Also, the taxonomy of these spiders has been fluctuating. For a time, some experts attempted to transfer this species to Phrixotrichus and you may find a paper to two on the venom of Phrixotrichus spatulata, which is the same spider. As of this writing the experts appear to have reversed themselves and have returned this to Grammostola but are now using the species name G. rosea. Characterized Toxins

Grammostola
rosae (=spatula) is a common Chilean tarantula which has become popular in
the pet trade due to its attractive appearance and docile behavior. The spiders
which Spider Pharm uses were collected by anonymous collector(s) in Chile and
shipped through importers into the United States. Thus we do not locality data
for these spiders as we do for species which we collected ourselves.
