Why are spiders more scary than sharks?

[Jackalope]

Think the title says it all....

Given the amount of damage each creature can do, and one is our predator, why the imbalance??

Sharks don't crawl in and out of your mouth while you sleep.

Seen plenty of sharks while scuba diving - they're not nearly as threatening as you might expect. On the other hand, moray eels and stonefish I give a lot of respect to. Morays because they're hostile and capable of doing real damage, and stonefish because they aren't hostile - but they look like damn rocks and have extremely poisonous spines.
