A tarantula's blood is not true blood, but rather a liquid called hemolymph (or haemolymph). At least four types of hemocytes, or hemolymph cells, are known. The tarantula's heart is a long, slender tube located along the top of the opisthosoma. The heart is neurogenic as opposed to myogenic, so nerve cells instead of muscle cells initiate and ...
Grammostola is a genus of South American tarantulas that was first described in text by Eugène Louis Simon in 1892. [5] These medium- to large-sized spiders are native to tropical South America, and are usually brown in color, with pinkish or orangish-red hairs.
Some, such as those of the Chilean rose tarantula (Grammastola rosea) and the pinktoe tarantula (Avicularia avicularia), are fairly mild and innocuous to humans. Others, such as those of the Brazilian giant white knee tarantula ( Acanthoscurria geniculata ), are moderately irritating.
The Chilean recluse spider, Loxosceles laeta, is a highly venomous spider of the family Sicariidae.

Phrixotoxins are peptide toxins derived from the venom of the Chilean copper tarantula Phrixotrichus auratus, also named Paraphysa scrofa. Phrixotoxin-1 and -2 block A-type voltage-gated potassium channels; phrixotoxin-3 blocks voltage-gated sodium channels. Similar toxins are found in other species, for instance the Chilean rose tarantula.
