Anyone with mild or moderate depression can potentially benefit from cognitive behavioral therapy, even without taking medication. A number of studies have shown CBT to be at least as effective as antidepressants in treating mild and moderate depression.
Theraphosids (tarantulas and baboon spiders) are the longest lived spiders having a lifespan of more than 20 years in captivity. Unsurprisingly, all these longest lived spiders are females as males have shorter lifespansâafter reaching maturity (within a year or two) they mate and die.
The spider is a bit larger than the top of a soda can, and it's black except for a large, cobalt-blue band on its abdomen. The tarantula also sports blue markings on each of its limbs and the pincers by its mouth, Snyder said. The newfound spider isn't the only known blue tarantula. For instance, the greenbottle blue tarantula (Chromatopelma cyaneopubescens) is blue, as is the Gooty sapphire ornamental tarantula (Poecilotheria metallica). It's also common for tarantulas to live in trees, but the finding still raises all sorts of questions.
