Legless for 100+ million years: snaking through evolution across land and sea

New fossil finds and genomic studies illuminate how snakes rose to dominance over 100 million years: likely starting on land, they gradually shed their legs (roughly 150–125 million years ago) and evolved a highly flexible skull and jaws, enabling diverse diets and habitats from burrowing to aquatic life; fossils like Najash and Dinilysia hint at mixed terrestrial underground origins, while ongoing genome work aims to clarify their closest relatives and the genes behind limb loss.

Big Backyard Snakes: Nonvenomous Rodent Helpers in Your Garden

Black rat snakes can reach up to nine feet, are non-venomous constrictors, and are beneficial garden predators that help control rodent populations. They may hiss or coil to mimic rattlesnakes when threatened, but pose little risk to people or pets; bites are rare and typically minor if they occur. Size and growth vary with food availability and climate, making a healthy yard a good habitat for these snakes, which can reduce pest problems without human intervention.

Snake Cannibalism Revealed as an Adaptive Response to Scarcity

A Biological Reviews study analyzing hundreds of reports across 207 snake species finds that cannibalism is widespread and has evolved at least 11 times, indicating it’s an adaptive survival strategy in response to ecological stress and food scarcity—occurring in both the wild and captivity to regulate populations and boost ecological fitness; some experts caution against broad generalizations across all species.

Snake Cannibalism Emerges Independently at Least 11 Times, Study Finds

A review of 503 cannibalism reports across 207 snake species finds cannibalistic behavior has evolved independently at least 11 times, in both wild and captive settings. Cannibalism occurs across diverse contexts and is often tied to environmental stress or opportunistic feeding. Jaw structure enabling swallowing other snakes, along with dietary flexibility in some species, may help explain the pattern. The study suggests cannibalism is more common in snakes than previously thought and may be an adaptive response to scarce resources.

Cannibalism in Snakes: Evolutionary Trick Repeats Across 11 Lineages

A review of 503 cannibalism reports across 207 snake species finds that cannibalistic behavior has evolved independently at least 11 times. The behavior appears across continents and contexts, often linked to environmental stress or scarce food, with many captivity cases; jaw flexibility and dietary generalism help some snakes consume conspecifics. Researchers say cannibalism can provide ecological fitness as an opportunistic feeding strategy, though much of the data are anecdotal and more study is needed.

"The Evolutionary Advantage of Snakes: Unraveling the Mystery"

Scientists have found that snakes possess a unique ability to evolve at an accelerated rate compared to other reptiles, allowing them to diversify and spread across the world. A recent study revealed that snakes evolved three times faster than lizards, with their rapid evolution continuing to this day. This flexibility enables them to quickly adapt their body shape and diets, leading to their success as an evolutionary "winner." However, the reason behind snakes' fast evolutionary clock remains a mystery, leaving scientists with new questions to answer.

"Multiple Rattlesnakes, Including 9 Babies, Evicted from Oro Valley Home"

The Golder Ranch Fire Department removed a total of 11 snakes, including 9 baby rattlesnakes, from a home in Oro Valley, Arizona. As the weather becomes slightly cooler and more humid, there is an increased likelihood of encountering snakes. If you come across a snake, it is important to stay calm, step out of striking range, and walk away without agitating the snake. If snakes are found on your property, call 911 for assistance with removal.

Snake Infestation: Wisconsin Hotel Guests Encounter Reptiles in Pool and Hot Tub

Guests at the Country Inn and Suites by Radisson in Germantown, Wisconsin, were shocked to find snakes in the pool, hot tub, hallway, and even a guest room. The snakes, believed to be northern water snakes, were likely from the wetlands behind the hotel. While some guests took matters into their own hands to remove the snakes, the hotel refused full refunds and blamed a guest for the incident. Choice Hotels, which owns Radisson, declined to comment. The hotel claims it has taken steps to prevent similar incidents in the future.

"Record-breaking Heat Triggers Early Start to Snake Season in Australia"

Unusually high temperatures in Australia have caused snake season to start early, with the Australian Reptile Park issuing an "urgent warning" for people to be on the lookout for venomous snakes. The rise in temperatures and winter rainfall has created the perfect environment for snakes to become more active. Snake catchers have reported a significant increase in callouts, a phenomenon rarely seen at this time of year. As global temperatures continue to rise, Australia's winters have been steadily warming. In the UK, rising temperatures are also affecting the snake population, with more pet snakes breaking free from their enclosures due to the warming climate.
