The statistic that more people are killed by falling coconuts than by shark attacks is an urban legend, that gained momentum when in 2002 the director of the International Shark Attack File, falsely claimed that falling coconuts kill 150 people each year, compared 5 shark attack deaths.
The majority of coconuts are picked by trained monkeys. Most coconut oil and meat comes from Thailand where monkeys are used to climb trees and retrieve coconuts. Male monkeys on average get 1,600 coconuts a day, humans only get about 80.
Coconuts managed to migrate to the Caribbean by floating across the ocean.
The water from a freshly opened coconut can be safely injected into human veins in place of sterilized water-for-injection.
