Name all the venomous animals you can think of and you probably come up with snakes, spiders, bees, wasps and perhaps poisonous frogs. But catfish? A new study by University of Michigan graduate student Jeremy Wright finds that at least 1,250 and possibly more than 1,600 species of catfish may be venomous"”far more than previously believed. The research is described in a paper published online Dec. 4 in the open access journal BMC Evolutionary Biology. Lest anyone have concerns about...

In contrast to the exhaustive research into venom produced by snakes and spiders, venomous fish have been neglected and remain something of a mystery. Now, a study of 158 catfish species, published in the open access journal BMC Evolutionary Biology, has catalogued the presence of venom glands and investigated their biological effects. Jeremy Wright, from the University of Michigan, USA, carried out the investigation. He said, "I used histological and toxicological techniques to elucidate the...

A harmless digestive enzyme evolved twice into a dangerous toxin in 2 unrelated species Biologists have shown that independent but similar molecular changes turned a harmless digestive enzyme into a toxin in two unrelated species -- a shrew and a lizard -- giving each a venomous bite. The work, described this week in the journal Current Biology by researchers at Harvard University, suggests that protein adaptation may be a highly predictable process, one that could eventually help discover...

While studying a way to more safely and effectively collect snake venom, University of Florida researchers have noticed the venom delivered by an isolated population of Florida cottonmouth snakes may be changing in response to their diet. Scientists used a portable nerve stimulator to extract venom from anesthetized cottonmouths, producing more consistent extraction results and greater amounts of venom, according to findings published in August in the journal Toxicon. The study of venoms is...

Researchers in China have discovered the first protein-based toxin in an amphibian "“a 60 amino acid neurotoxin found in the skin of a Chinese tree frog. This finding may help shed more light into both the evolution of amphibians and the evolution of poison.While gene-encoded protein toxins have been identified in many vertebrate animals, including fish, reptiles and mammals, none have yet been found in amphibians or birds. In the case of poisonous amphibians, like the tropical poison...

Scientists studying Staphylococcus bacteria, including methicillin-resistant S. aureus (MRSA), have discovered a potent staph toxin responsible for disease severity. They also found the gene for the toxin traveling with a genetic component of Staphylococcus that controls resistance to antibiotics. The study, now online in PLoS Pathogens, shows for the first time that genetic factors that affect Staphylococcus virulence and drug resistance can be transferred from one strain to another in one...

A Chinese team of scientists has identified the protein composition of venom from the Scorpiops jendeki scorpion. Wuhan University researchers said their findings -- from the first venom analysis of the arachnid -- uncovered nine novel poison molecules never before seen in a scorpion species. The scientists led by Yibao Ma of the university's Laboratory of Virology studied the sting of S. jendeki, a member of the family Euscorpiidae, which covers Europe, Asia, Africa and North America. Our...

Transcriptomic tests have uncovered the protein composition of venom from the Scorpiops jendeki scorpion. Researchers writing in the open access journal BMC Genomics have carried out the first ever venom analysis in this arachnid, and discovered nine novel poison molecules, never before seen in any scorpion species. Yibao Ma worked with a team of researchers from Wuhan University, China, to study the sting of S. jendeki, a member of the family Euscorpiidae, which covers Europe, Asia, Africa,...

A janitor at a department store in downtown Melbourne survived a bite by a deadly snake lurking in a dumpster, medical workers say. Paul Bentley, a spokesman for Ambulance-Victoria, said the 29-year-old told emergency workers he was throwing out trash in an alley behind the Myer store when he felt a bite on his finger, The Age reported. He pulled his hand out and saw an 8-inch snake with its fangs in his finger. Workers at St. Vincent's Hospital said they found venom from a brown snake on the...

The Western Diamondback Rattlesnake, Crotalus atrox, is a species of venomous rattlesnake found in the United States and Mexico. It is found in California, Arizona, New Mexico, Oklahoma and Texas. It prefers flatlands and prairies to the rocky hills and low mountains. This snake is generally colored dark or light brown. Its pattern is a unique row of large, dark diamond shapes edged in yellow trim, running down the length of its body. The diamonds fade to dark rings around the tail, where...

Rattlesnakes are a group of venomous New World snakes (genera Crotalus and Sistrurus) which have a small jointed rattle on their tails. They use this rattle as a warning device when they feel threatened. The rattle is composed of a series of nested, hollow beads which are actually modified scales from the tail-tip. Each time the snake sheds its skin, a new rattle segment is added. Since they may shed their skins many times a year (depending on food supply and consequent growth rates), and...
