The irukandji, sea wasp, or box jellyfish (class Cubozoa) is one of the most venomous jellyfish in the world, and are potentially fatal to human beings, though some species can be as small as your fingernail. It’s no wonder, then, how this small fish ends up dead as a Julius Caesar within seconds of being ensnared.

Watch a box jellyfish makes quick work of a helplessly curious little guppy, lured to its death by the jelly’s tentacles, which offer the deceptive, false promise of a meal:

Acclaimed photographer Susan Middleton’s gorgeous new coffee table book, “Spineless” showcases portraits of just about every marine invertebrate (animals without backbones) you could think of. Middleton’s opening paragraph sets the stage with two quotes from giants of the fashion world – as analogous to the natural world.

 “What we imagine may be very beautiful but nothing replaces reality.” – Yves Saint Laurent

 “There is no better designer than nature.” – Alexander McQueen

 In Spineless, Middleton explores the mysterious and surprising world of marine invertebrates, which represent more than 98 percent of the known animal species in the ocean. They are also astonishingly diverse in their shapes, patterns, textures, and colors—in nature’s fashion show, they are the haute couture of marine life.

Jellyfish have organelles called nematocysts, which work like hypodermic needles when engaged, breaking through the tentacle and ejecting venom. For the first time, this process has been captured on film under a microscope (using an anemone, which are related to jellyfish) at James Cook University.

$220 Glow-in-the-Dark Ice Cream Made From Jellyfish

Charlie Harry Francis and his company, Lick Me I’m Delicious, have succeeded in finding the sweet tooth’s response to the $300,000 test tube burger: A glow-in-the-dark ice cream synthesized from a jellyfish protein that causes luminescence when it reacts with calcium.

But why so expensive? Couldn’t anything drifting past northern Japan give off this luminescent green hue? According to Francis, “Jellyfish luminescence is four times pricier than gold so each scoop costs me around £140.”

Zinc May Prevent the Effects of Jellyfish Venom

The Australian box jellyfish contains one of the world’s deadliest known venoms.

After being stung by a box jellyfish in Hawaii, Dr. Angel Yanagihara (University of Hawaii at Manoa) set out to discover a new remedy. Testing on both mice and humans (including herself, she admits), Dr. Yanagihara found that zinc can prevent the venoms of both Hawaiian box jellies and the deadlier Australian box jellies from creating pores in human red blood cells, which results in the leaking of precious potassium.

Jellyfish Welts Stinging and Bob Dylan Singing, Across the Ocean

Those are box jellyfish stings that Diana Nyad, ultra marathon swimmer, sustained 90 miles into an attempt to swim from Cuba to Florida. Elizabeth Weil has an amazing profile in the NYTimes about ultra distance swimmer Diana Nyad. Soon after the lede has a fascinating lead. She counts her time in the ocean by singing Bob Dylan’s “It ain’t me, babe”, the Beatles’ “Paperback Writer” and other songs from a mental playlist of 65 tunes.

 “When I complete 2,000 ‘It Ain’t Me, Babe’s, Bob Dylan version, I know I’ve gone 4 hours and 45 minutes exactly,” Nyad says. “I never lose track.”

The story has too many wonderful details in it to be missed, spanning Diana’s childhood mentors and villains, her Muhammad Ali like bravado that she displayed to the world in her 20s, and detailing the extreme sacrifice, physical and emotional, that she and her loved ones go through in her quest to swim from Cuba.
