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.
One of Africa's largest living spiders is the king baboon tarantula. It has a leg span of up to 8 inches (20cm) and is rusty red-brown in colour. In the wild it digs into the soil of grasslands, then constructs webs across its burrows to catch prey.
