Hawaii's Dolphins Can't Get Any Sleep Because of Tourists

Illustration for article titled Hawaii's Dolphins Can't Get Any Sleep Because of Tourists

Tourists in Hawaii really like to see dolphins, and that's fine because dolphins are magical (when they're not trying to bad-flipper isolated swimmers or murder innocent tiger sharks), but it's also creating a significant problem: insomniac dolphins aren't getting enough sleep because tourists keep wanting to stare into a sea mammal's soul and suddenly understand all the many thalassic mysteries.

Spinner dolphins — whose aerial acrobatics make them a big favorite with dolphin-sycophants — spend most of their days sleeping in the shallow protected bays around the Hawaiian Islands, coming more alive at dusk, which, for all you "Shark Week" devotees, is that magic oceanic hour when sea creatures come alive and murder each other gorily. The problem with this schedule, however, is that it inconveniences all the mouthbreathers from the mainland, who visit Hawaii and embark on a two-hour ocean kayak adventure that involves feeding pterodactyl-sized seagulls whole sleeves of Saltines and chasing sleepy dolphin from cove to cove.

As a result of tourists' eagerness to see the very dolphins that Lisa Frank mythologized in her dolphins-jumping-through-the-rings-of-Saturn Trapper Keeper series, spinner dolphins haven't been getting as much sleep as they require, say scientists at Duke and Stony Brook University, which could eventually interfere with their ability to find food, avoid predators and communicate with Aquaman. "Sleep is essential for most animals," explained marine scientist at Duke University David W. Johnston.

When deprived of their necessary 'zzzz's,' they gradually show a decreased ability to process information and remain attentive to environmental stimuli. In technical lingo, we call this a 'vigilance decrement.'

People, in their naive eagerness to maybe pat a dolphin on the head or try to establish some sort of psychic connection starting contest, may actually be keeping dolphins from relaxing, which is really selfish but totally unsurprising considering humans ruin just about everything that's awesome about nature. Boo on us.

DISCUSSION

Shouldn't the people that organize the kayak tours and such be the one to put the kibosh on the dolphin viewing? I don't really feel the blame should be put on the visitors - do we expect people to research the sleeping habits of the animals in the area they're visiting when they go everywhere? It should be the responsibility of the people running the tours to make sure that they're done at a time that doesn't ruin the dolphin's sleep patterns. Their job is to know about the dolphins.
