Planes on a snake? Scientists discover various crab species hitching rides on sea snakes
Confirmed
In Short: Scientists have discovered a sea snake species, Pseudocerastes urarachnoides, that has evolved a tail resembling a spider, a behavior known as caudal luring, which helps it catch prey.
Scientists have discovered a sea snake species, Pseudocerastes urarachnoides, that has evolved a tail resembling a spider, a behavior known as caudal luring, which helps it catch prey. This mimicry, observed in dozens of snake species, involves the snake jiggling its tail to attract unsuspecting prey, making it appear as if a spider is moving across the rocks.
The discovery of this bizarre adaptation was initially met with confusion, as researchers initially thought the growth on the snake's tail was a deformity. However, recent studies using high-resolution micro-CT scans have revealed that the tail is not a bone but a modified soft tissue, suggesting it arose through evolutionary processes.
This unique adaptation has been documented in various studies, but the skeletal anatomy of the spider-tailed horned viper has never been comprehensively examined. The research, published in The Anatomical Record, provides new insights into the evolutionary processes that led to this fascinating trait, which has not been preserved in fossil records due to the absence of bone in the tail.
The study, led by researchers from the University of Florida, highlights the importance of modern imaging techniques in understanding the complex adaptations of animals. The findings not only add to the scientific understanding of snake behavior but also demonstrate the remarkable diversity of evolutionary strategies in the animal kingdom.

What's still developing
- By sequencing the DNA of soil microbes thriving on the plastic, the scientists identified a bacterial enzyme, which they named LCPH1, that closely resembled a class of proteins bacteria use to disable penicillin-type antibiotics.
- Biologists studying how bacteria break down a new generation of plant-based bioplastics — long-chain aliphatic polyesters — have discovered an enzyme that can dismantle both plastic and antibiotics.
- But subsequent discoveries revealed the spider-like growth isn't a bug.
- When scientists first encountered a specimen of the viper decades ago, they initially thought the odd growth might be a deformity of some kind.
- In 2012, Pfaller discovered that sea snakes might shed a lot more than just their skin when it’s time to molt.
- Dr. Sharon Nachman, chief of pediatric infectious diseases at Stony Brook Children’s Hospital in New York, shares what to know about the newly discovered Asian longhorned tick nairovirus.
- Scientists in China have identified a previously unknown tick-borne virus that can cause flu-like illness, fatigue and gastrointestinal symptoms, according to a new study.
- The newly discovered virus, the Asian longhorned tick nairovirus (ALTNV), which is part of the orthonairovirus group, has also been found to cause thrombocytopenia (reduced blood platelet counts) and laboratory evidence of liver-cell injury or inflammation.
