I think I would rather study the tarantula because tarantulas periodically shed their external skeletons in a process called molting. Eww! Their mild venom is weaker than a typical bee's. They also don't use a web to ensnare prey, though it may spin a trip wire to signal an alertwhen something approaches its burrow. Few natural enemies... which is a good thing!! But a wasp will paralyze a tarantula with its sting and lay its eggs on the spider's body. Eewww..
The thing that intreques me the most about them is that they can't get killed by many things but the ones that they can get killed by are wasped... interesting...
What do you think?
