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.
Tarantulas sizes range from as small as a fingernail to as large as a dinner plate when the legs are fully extended. Depending on the species, the body length of tarantulas ranges from 2.5 to 10 centimetres (1 to 4 in), with leg spans of 8â30-centimetre (3â12 in). Leg span is determined by measuring from the tip of the back leg to the tip of the front leg on the opposite side.
