    “These three little guys are part of a species of hermit crab that has never been discovered alive. The Pylopagurus discoidalis were discovered on a submarine dive in the Caribbean and are named The Three Amigos, after the movie. Which one is the most Steve Martin-like?”

    “Meet the blob fish! “They’re found off the deep waters off the coasts of mainland Australia and Tasmania and are rarely seen by humans. The flesh of the blob fish is primarily a gelatinous mass with a density slightly less than water, allowing the fish to float above the sea floor without expending energy on swimming.”

    Tuatara

Wikimedia Commons


"The tuatara is a reptile native to New Zealand. You might look at it and think it’s a lizard like so many others, but in fact, it is a very unusual branch of the reptile tree and is not closely related to any extant lizards or snakes. In fact, it’s not a lizard at all; it’s a very primitive reptile that shares almost as many traits with birds as it does with lizards, which makes it of great interest to evolutionary biologists.
"The tuatara is unusual for lots of reasons; it has a single-chambered lung, the most primitive heart of any reptile, its teeth are not teeth but rather jagged outcroppings of its jawbone, its spine resembles that of a fish more than any other reptile, and, oh, wait, it has three eyes. Yes. Three eyes. And its lifespan is just as weird; it reaches sexual maturity extremely late, at between 20 and 30 years, and doesn’t even stop growing until its 35th year. That means the tuatara is also extremely long-lived, frequently breaking the century mark. A tuatara named Henry became a father at age 111, back in 2009, and some experts believe the tuatara could reach 200 years in captivity.”
(A reptile with a 3rd eye, at an evolutionary point millions of years behind modern lizards. Interesting. -RS)

    The Immortal Jellyfish

Takashi Murai


"Let’s start with the oldest-living animal of all, and one of the strangest in the entire animal kingdom: Turritopsis nutricula, otherwise known as the immortal jellyfish. You might think that this animal’s common name is poetic, that perhaps it lives for a few hundred years, impressing generations of scientists—but you’d be wrong. Its name is literal: Turritopsis nutricula is biologically immortal.
"The immortal jellyfish can theoretically live forever, thanks to a process that is believed to be unique, called transdifferentiation. It has the ability, at any stage in its life, to completely transform back into a polyp, its earliest stage of life. You can imagine it like the mythical phoenix, an immortal bird which is repeatedly reborn as a chick. The immortal jellyfish doesn’t die; it merely regenerates its cells in a younger stage, then ages naturally again.
"That doesn’t mean all Turritopsis nutricula are immortal; the species is a small invertebrate in the ocean, and is susceptible to all of the nasty things that can befall such creatures, whether that’s being eaten or succumbing to disease. But it is biologically capable of immortality. The New York Times Magazine ran a great article about the immortal jellyfish last year—highly recommended reading.”
