I wondered about this until one day I picked one up that seemed stuck to the sand. At first, I thought the tentacle had simply been buried in the sand by the surf action. These little one-inch crabs live buried in the sand near the shore break. It doesn't take long for the entire tentacle to be gone, a good thing for us humans, since stinging cells on the tentacles can fire even after the creature is dead. More dangerous, though, are bees.
Honey bees cause more deaths in the United States every year than snakes, sharks or jellyfish.
Most people have only minor discomfort from bee stings, but a few are allergic. In these cases, a sting can quickly kill a person. It's common to see honey bees tumbling in the Kailua surf or staggering near the waterline, especially in the summer when bee activity is high. Entomologist Michael Kliks of the Manoa Honey Co. said these bees are probably senile foragers that got confused about where they were going. Yes, honey bees get senile.
