“The cow and the bear themselves will feed; together their young ones will lie down. And even the lion will eat straw just like the bull. And the sucking child will certainly play upon the hole of the cobra . . . They will not do any harm or cause any ruin in all my holy mountain.”—Isa. 11:7-9.
The watchtower teaches that before the flood, all animals were vegetarians. God didn't DESIGN animals to be brutal killers, he designed them to live together in peace. So every animal that 'appears' to be adapted strictly to feed off other animals, is just misusing the traits god gave it to eat vegetation. (As evidenced by Watchtower 1969 9/1 P.543-544)
Lets take just one example: The Trapdoor Spider.
The trapdoor spider digs a hole, normally in the ground, and seals off the entrance with a plug. It attaches a silk hing to this plug which allows it to quickly pop out and attack whatever 'plant' is near it's entrance. It also lays out little silk 'tripwires' which, when triggered, alert the spider to the presense of something outside.
(Please note that, since most plants don't react very quickly to danger, the element of suprise may seem 100% useless while hunting plants. This is because you don't know any better.)
It camouflages its hole with dirt and leaves to make it look as indistinquishable from it's surroundings as possible. (Please note that, since most plants don't have eyes, camouflage may seem 100% useless in hunting plants. this is because you don't know any better.)
Living underground is NOT particularly easy. The trapdoor spider can't just dig a hole and live in it until a 'plant' happens to walk by. It has to line the hole with silk so that the borrow doesn't collapse. It also has to make sure the lid is water tight so it doesn't get flooded.
And it seems that wasps have gone against gods original design, since the wasps will find a way into the trapdoor spider's hole and lay eggs in it. The eggs hatch and release larva which eat the spider from the inside out. So the trapdoor spider makes little branches and secondary chambers in it's hole which it can seel off or escape through. (Note that in the absense of predators, a defense mechanism may seem almost entirely useless. This is because you do'nt know any better.)
So hopefully I have shown that the trapdoor spider was hand designed by a loving god to be the ultimate plant-trimming-machine.
