Default Re: Would a 9 lb sapient spider producing 1/10 lb of silk a day suspend your disbelie

9lbs may be too small for sapience but that's pretty fuzzy. How much of that body mass is brain though?
Actually 9lbs is more the typical weight... they get up to about 38lbs at their largest.

However... they grow throughout their entire lives (I think about 60 years), so if the spider in question does the same, they might not reach "sentience" until well being past "middle-aged".

They cite 14,000 spiders to make 1 ounce of silk, or about 0.00007 oz per spider per day.

These golden orb spiders weigh maybe around 0.035 ounces, or about .002 of silk per ounce of spider.

You're scaling them up about 4,000 times to get to 9 lbs, so you should be ok with about an 8 oz max in a day for a 9 lbs spider.

Mind you, if you do milk the spider for all the silk it's worth you may need to give it time to replenish itself before milking it completely again.
Forgive me, but using those numbers I get something more akin to 1/50th a pound, or about 0.3 ounces.
