Osedax is a genus of weird, deep-sea polychaetes worms, commonly known as boneworms, zombie worms, or bone-eating worms.



The story of these creatures began twelve years ago, when researchers from the Monterey Bay Aquarium Research Institute (MBARI) first discovered them, using the submarine ROV Tiburon in ... Read more »

Electroreception is the biological ability to perceive natural electrical stimuli or in simpler words, the ability to perceive the world via electricity.

Non-Echolocating Bats Actually Echolocate Using Wing Clicks

by beredim in Strange Animals

Spectacled flying fox (Pteropus conspicillatus)A non-echolocating speciesCredit: MnolfContrary to what most people think, bats are not blind. The truth is that all one-thousand something bat species can see. Most people also think that since bats are blind they rely on their echolocation to get around. Again a mistake, since many bats don't possess echolocation.For example, most species of Megabats [Suborder: Megachiroptera] have to rely exclusively on their vision. Or that's what we thought up ........ Read more »

As A Bird - It's No Turkey

by Mark Lasbury in As Many Exceptions As Rules

The turkey is an amazing bird, beyond it’s taste on Thanksgiving. It has some really funky structures on its head, like the caruncles, wattle and snood, but research shows that they are important in mate selection. The question is why they have been retained even though they are artificially bred nowadays. Maybe they are for more than just mate selection. And yes....turkeys can fly.... Read more »

Researchers Design Cyborg Cockroaches for Search and Rescue Missions

by beredim in Strange Animals

Cyborg CockroachCredit: Eric Whitmire.Researchers at the North Carolina State University (NCSU) issued a press release today announcing that they have developed "cyborg" cockroaches with electronic circuit boards strapped to their backs. The cyborg cockroaches (or biobots) can be used to pick up sounds with their attached microphones and seek out their source.Hopefully, the technology will one day help emergency personnel to find and rescue survivors in the aftermath of disasters, like earthquak........

Doing More With Less

by Mark Lasbury in As Many Exceptions As Rules

Animal-like protists are similar to animal cells, but they do many things in their single cell that we have a hard time competing with. New research shows that they may be useful in medicine, as well as lethal in some cases. N. fowleri is a brain eating amoeba, but calcium tests of foraminifera may be helpful in bone grafts and repairing skull fractures.... Read more »

Four Solar-Powered Animals

by beredim in Strange Animals

Photosynthesis, a process used by plants and some bacteria to convert light from the sun into chemical energy which can be later released to fuel their activities. Animals on the other hand, have to consume other organisms in order to cover their energy needs. But every rule has an exception.In recent years, researchers have discovered a small number of animals that much like plants have found a way to directly harness and feed off the Sun’s energy.1# Oriental Hornet (Vespa orientalis)Typicall........

Frankenstein Meets Genetic Modification

by Mark Lasbury in As Many Exceptions As Rules

Halloween conjures up monsters, like Mary Shelly’s Frankenstein. Her story is just as applicable for us today – the story of science being responsible for what it creates. The so-called Frankenfoods are called dangerous – but why? Studies that label them dangerous have been retracted or are merely correlative. New studies have shown that genetically modified crops are safe for livestock and humans. However, there are valid concerns, so every GMO must be tested rigorously.... Read more »
