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.
Some of the largest species of tarantula may weigh over 85 grams (3 oz); the largest of all, the goliath birdeater (Theraphosa blondi) from Venezuela and Brazil, has been reported to attain a weight of 170 grams (6.0 oz) and a leg-span of up to 30 centimetres (12 in), males being longer and females greater in girth.
