Tarantula - Mexican Redrump
a species of tarantula known commonly as the Mexican red rump. It ranges predominantly in Mexico (including the Yucatán Peninsula), but is also found in Central America. They are terrestrial, burrowing spiders. The reason for the name red rump is because of its distinctive red hairs on its abdomen. Like most tarantulas, they will eat anything they can overpower, which is usually insects, but small lizards and rodents may also be consumed. They can grow up to a solid 6.5 inch leg span, with males typically being smaller and thinner than the females. They prefer shrubland habitats. The Ch'ol Maya consider these spiders to be positive, and use them medicinally. A hierbatero kills it, then crushes it, mixes it with spirit alcohol and strains out any irritating hairs with a traditional cloth. The beverage is used for the treatment of "tarantula wind", the symptoms being chest pain, coughing and asthma. The venom peptide GsMtx-4 is being investigated for the possible treatment of cardiac arrhythmia, muscular dystrophy and glioma.
