America's rarest snake dies while swallowing centipede: ‘We were all totally flabbergasted’

The rarest snake in North America spotted earlier this year in Florida has died.

According to the Florida Fish and Wildlife Conservation Commission, the rim rock crowned snake died while trying to swallow a prey – a giant centipede about a third of the snake's length.

Researchers said they believe the size of the centipede cut off the snake's air supply at its widest part. Its venomous pincers attacked the inside of the snake, causing internal bleeding.

“I was amazed when I first saw the photos,” Coleman Sheehy, the Florida Museum’s herpetology collection manager and author of the study said in a press release. “It’s extremely rare to find specimens that died while eating prey, and given how rare this species is, I would never have predicted finding something like this. We were all totally flabbergasted.”

Scientists opted for CT scans instead of dissection to keep the snake as intact as possible for further study on the elusive species.

“We were able to perform a digital autopsy, which allowed us to examine the centipede and snake, including its injuries and gut contents, without ever picking up a scalpel,” Jaimi Gray, another of the researchers, said.

The rim rock crowned snake, or Tantilla oolitica, is one of several species of plants and animals that only exists from central Florida to the Keys along an ancient coral reef, according to the FWC.

“We can’t say for sure whether or not they’re still present in peninsular Florida,” Sheehy said. “Absence of evidence is not evidence of absence, but their habitat has basically been destroyed.”

Rim rock crowned snakes are tiny reptiles which can grow to less than a foot in length. They have black to light brown heads called crowns and are only found in a very small part of southeast Florida and the Florida Keys.

As cities expanded, the snakes’ numbers dropped. According to FWC, hurricanes and thunderstorms also flood their habitat, which is mostly underground in limestone. They can sometimes be found above ground in rotten logs or hiding under rocks or trash.

The Florida Museum has only cataloged 26 rim rock crowned snakes.

In the wild, life expectancy is about five years. After two years, the snake lays about six eggs per year, according to the FWC.

The Best Fish Feed in Nigeria for Catfish: Why Quality Matters

A few months ago, I visited a fish farm run by an ambitious aquapreneur who had high hopes for his homemade fish feed. His pond was large, his vision clear: this feed would cut costs, boost growth, and drive profitability. But within a week, disaster struck. Fish floated belly-up. Growth stalled. The numbers didn’t add up. The problem wasn’t the fish. It was the feed. The catfish were growing exactly as they were fed: poorly. Just as fish can’t flourish on empty calories, a farm can’t succeed on subpar feed. The right nutrition makes the difference between a thriving business and a sinking investment. In Nigeria’s competitive catfish farming industry, choosing the best feed isn’t just about cost, it’s about protein content, digestibility, floatability, and growth performance. The wrong feed leads to stunted growth, higher mortality, and lost profits. The right one maximizes yield, health, and market value. In this article, we’ll explore:...

Rough Collie Is Now The Most Aggressive Dog, According To Science

Often touted for being highly affectionate, Rough Collie has topped the list of 23 other types of dogs known to be “aggressive,” according to new study published in Scientific Reports. Researchers from Helsinki who studied the behaviour of more than 9,000 dogs covering 24 breeds found that Long-Haired Collies, like Rough Collie, Miniature Poodle, and Miniature Schnauzer are more likely than others to exhibit aggressive behaviour. The study also revealed that small dogs are more likely to behave aggressively than mid-sized and large dogs, but due to their size, are often not seen as threatening and the bad behaviour therefore goes unaddressed. Male dogs are also more aggressive than females and neutering them has no impact. The researchers noted that Labradors and Golden Retrievers known for their docile temperament and gentle nature, are the least aggressive dog breeds. Notable breeds such as Rottweilers, Dobermans and British Bulldogs were however not included in the list. ...
