The Swimming Sea Cucumber and the Exploding Paint Pack

Sea cucumbers aren’t all boring, trundling bags. Some of them swim — and glow. Though I opted to focus on creatures found at greater depths in my last post, one of the creatures observed by the Deepsea Challenger expedition in the New Britain Trench at a relatively shallow 1000 meters was just such a swimming [...]

True-ish (and Hilarious) Facts About the Anglerfish

Anglerfish and comedy always seemed like a natural pairing. But it took internet humorist Ze Frank to bring the two together in one delicious dish. The natural history documentary parody series “True Facts About …” by Frank has become a minor youtube sensation. I’d seen one of his works before “True Facts About Land Snails” [...]

Cameron’s Team Divulges Discoveries in Deepest Trenches on Earth

xenophyophore_noaa_pd_200

It’s often said that we know less about the bottom of our own ocean than we do about the surface of Mars. The governments of the world, and our government in particular, seem presently much less than enthusiastic about exploring the oceans of our own planet than in exploring other planets (ocean research seems to [...]

Here it is in its original context (don’t miss the caption!). Here’s another, of a free-living marine nematode called Draconema (see [...]

Nematode Roundworms Own This Place

roundworm_Toxocara_canis_Joel_Mills_wiki_cc_200

The next time you find yourself becoming mosquito chow, remember this video: This is Strelkovimermis spiculatis — a parasitic nematode, or roundworm — casually escaping from an unlucky, soon-to-be-expired mosquito larva. The way this larva twitches as the nematode slithers out is gut-wrenching. You can still see the poor larva’s vitals pumping even after nematode [...]

The Startling Mechanical Beauty of a Rotifer in Motion

bdelloid_rotifer_wiki_cc_diego_fontaneto_200

This curious creature, captured here under the microscope, is not a protist. It’s an animal. An animal, in fact, that can be smaller than some unicellular microbes. It’s a rotifer, and its stock in trade is sucking tiny prey to their doom. These multi-cellular micro-animals — which, let me emphasize again, are smaller than some [...]

Take This Shell and Shove It: The Mollusk That Became a Worm

aplacophoran_noaa_pd_200

When you think of a mollusk, you probably have something shelled, slimy, and possibly stalk-eyed in mind. But mollusks include creatures that are none of these things. In fact, there are mollusks that are wormy, be-spined, and eyeless. They are called aplacophorans, and scientists have long puzzled over their place in the mollusk family tree. [...]

Were Weirdo Ediacarans Really Lichens, Fungi, and Slime Molds?

tribrachidium_wiki_cc_aleksey_nagovitsyn_200

Does these look like lichens to you? According to Gregory Retallack, they should. Yesterday, Nature published an article by Retallack that makes a radical claim: the Ediacaran Biota (635-542 mya) of bizarre creatures that preceded the Cambrian Explosion were not pneumatic semi-mobile marine animals, but instead sessile land-dwelling lichens and protists living high and very [...]

Laughing rats and ticklish gorillas: Joy and mirth in humans and other animals

Last week, while in a drowsy, altitude-induced delirium 35,000 feet somewhere over Iceland, I groped mindlessly for the cozy blue blanket poking out beneath my seat, only to realize—to my unutterable horror—that I was in fact tugging soundly on a wriggling, sock-covered big toe. Now with a temperament such as mine, life tends to be [...]

Until recently, the only association I made between dogs and pantyhose would have involved an unfortunate trip to the vet.

Nearly extinct giraffe subspecies enjoys conservation success

west African giraffe

The rarest of the nine giraffe subspecies, the West African giraffe (Giraffa camelopardalis peralta), almost didn’t make it to the 21st century. After years of being poached and losing habitat to development, only 50 of these animals were left in Niger in 1996, and the subspecies’s future seemed bleak. But today, just 13 years later, [...]

How much is a wolf worth in Idaho? $11.75

Gray wolves have a price tag on their heads in Idaho, and it’s a bargain-basement price at that. Starting Monday, Idaho residents can get wolf-hunting permits for just $11.75 (after purchasing a state hunting license for $12.75, of course). Nonresidents have to pay a bit more: $154.75 for a hunting license, plus $186 for a [...]

When Cells Discovered Architecture

In early 1997, while still a freshman in college pondering whether to study biology or archaeology, I opened up my copy of Discover Magazine to find an article that startled and captivated me.

Bambi or Bessie: Are wild animals happier?

We, as emotional beings, place a high value on happiness and joy. Happiness is more than a feeling to us – it’s something we require and strive for. We’re so fixated on happiness that we define the pursuit of it as a right. We seek happiness not only for ourselves and our loved ones, but [...]

Butterfly watch: multi-generational migrations

The Painted Lady butterfly, Vanessa cardui. Picture taken in Ename, Belgium Tim Bekaert (July 12, 2005).

Migrating animals are always impressive to watch. The ability to cover huge areas of land in massive groups can be a beneficial strategy for many animals; whether birds, mammals or shoals of fish. Yet even more impressive than migrations by groups of individuals are those that take place over several generations. In the case of [...]

How the animals lost their sensors

The components of the two-component signalling system. Picture (c) me.

For free-living organisms, the ability to sense and respond to the outside environment is crucial for survival. Eukaryotes, such as animals and plants, often have highly complex network systems in place to monitor their surroundings and respond effectively, but bacteria have developed a remarkably simple system. It’s called the ‘Two Component System’ because it literally [...]

How to milk a pigeon

Milk is produced by mammals in order to provide nutrition to their growing young. It’s pretty special stuff, as not only does it provide all the nutrients and energy needed to fuel a growing baby (consider that for at least six months a human infant drinks nothing but milk) it also aids in the development [...]

The bacteria that make insects eat their own brains

An electon micrograph of an insect cell, with three Wolbachia bacteria inside (the large circular blobs with white lines surrounding them). Image from reference 2.

As far as bacteria are concerned, other living creatures are just another niche to exploit, which means that pretty much every animal and plant has a set of bacterial pathogens that come along with it. These bacteria have made the animal in question their speciality, and are highly adapted to live inside their hosts. While [...]

There’s been a lot of focus on the human microbiome recently, and while I’m obviously thrilled at anything which makes people think more about bacteria it’s easy to forget that it isn’t just humans who provide internal living space for bugs. Bacteria are everywhere, inside and among every living creature, and some of them form [...]

How cancer-causing bacteria force your cells to die

The discovery that stomach ulcers are caused by bacteria is quite recent and was proved fairly conclusively in 1984 when the Australian scientist Barry Marshall drank a petri-dish full of the bacteria Helicobacter pylori and five days later developed serious gastritis, which cleared after antibiotic treatment. As stomach ulcers are quite common, and can be a major [...]

3-D Imaging of Microfossils Muddies Case for Early Animal Embryos [Video]

The proverbial primordial soup from which our earliest, multi-cellular ancestors emerged was presumably seething with many much simpler, single-celled organisms.

A famous collection of minute 570-million-year-old fossils, from the Doushantuo [...]

Stress tests devised to reliably reveal personality in birds

Most dog and cat owners will happily describe their pet’s disposition down to the smallest, human-like detail. But how much of that is over-reaching anthropomorphizing and how much is an individual animal’s actual "personality" shining through? Researchers in the U.K. devised a series of tests to see how individual animals respond—both behaviorally and biologically—to different [...]

Mongoose mentors teach traditions through imitation

In Australia, some dolphins suit up for dinner. Before poking through seafloor mud for a delectable crustacean or cephalopod, the dolphins protect their sensitive snouts with marine sponges.
