In a huge win for conservation, the first ever nesting behavior has been observed by reintroduced female Siamese crocodile that resulted in two hatchlings! The hatchlings are now being headstarted by the Wildlife Conservation Society.
The authors note: “While collecting eggs for incubation in May 2022, we were able to identify a unique series of notched tail scutes on a female C. siamensis as she aggressively defended a nest.
“From these markings we determined the female was hatched on 11 August 2012 (age = 9.75 years) and released in March 2014. A camera-trap placed at the nest on 11 May 2022 and recovered on 5 July 2022 recorded 1724 images.
“These images indicated the female remained in attendance at the nest throughout the monitoring period. Camera-trap imagery captured eight nest repair events and two nest defense events; during the later the female defended the nest from village dogs.”
They have managed to reduce the mortality with their headstart program by an amazing 90%! To read the paper and full story, click here.

For over 500 species of frogs, Batrachochytrium dendrobatidis or more easily BD has been devastating. It has decimated populations worldwide and lead to extinctions of of 90 possible species threatening more world-wide. Scientists have been struggling to come up with a cure of any sort and have started to look at the possibility of infecting the fungus with a virus.
Meet BdDV-1, a viral fragment discovered by scientists whose paper was recently published by the journal Current Biology. The researchers found it in much the same way that one disentangles a knot, by pulling on individual threads to see where they lead. While examining the BD fungus to learn about weaknesses, they discovered a single-stranded DNA virus trapped within the genome of the fungus. Although this only applied to certain strains, when infected they produced fewer spores than the uninfected fungi. Now the next step is to see if researchers can clone and engineer this virus so that it kills BD and saves the frogs.
That will not be the easiest task to accomplish, however, for a big reason: Currently the virus makes the fungus more deadly to the frogs, rather than less so.
Now the question remains if they can reenginer the virus to change how it impacts the virus. To read more about the process, visit Salon here.

This is me, in all my Tinley Glory. If you need me, just grab me. I will always be there for you.
The best part about reptile shows is we can be ourselves. We are with our tribe. People who love the same things we do and it should be a fun and safe environment for all of us. The hard reality is that there are bad people everywhere in this world, no matter where you look.
This is going to be a very different post Tinley wrap and bear with me, it is going to probably be long but I promise reptile pictures from the show to lighten the mood that are not ball pythons or crested geckos at the end. Something happened that I felt needed to be addressed and shared even as vague as I intend on sharing. Let's just say, someone was naughty.

The autopsy report for the man who died after being bitten by his pet Gila Monster has been released and it lists three factors that resulted in his death. The report lists complications from envenomation of the Gila Monster, basically listed as an injury, but also listed an enlarged heart and a fatty liver as "significant contributing factors" in his death.
Around 11:45 p.m. Feb. 12, someone called 911 to report an animal bite, according to Lakewood Police. It was later determined to be a Gila monster bite.
The victim was taken to the hospital and died four days later. According to the autopsy report, the man suffered a "four-minute venomous Gila monster bite to the right hand."
He sought treatment about 2 hours after the bite. For more on the story, click here. The last known death from a Gila bite was in 1930 and the person may have had liver damage due to cirrhosis.

Caecilians are amphibians that look superficially like very large earthworms. New research suggests that at least one species of caecilian also produces "milk" for its hatchlings.Photo by Carlos Jared
Most people look at caecilians and think EWW. They are worm-like amphibians and although they have very adorable faces they are a more secretive animal and are often overlooked. Marta Antoniazzi, a biologist at the Instituto Butantan, in Sao Paulo, Brazil has been working with Siphonops annulatus for quite some time now. They noticed that while the babies fed on the mothers shed skin weekly, they were too active for that to be their sole source of nutrition. So they did what anyone would do. Set up a camera and waited.
"The babies prefer to go to the tail of the mother," he says.
And that's when they saw it. A secretion coming from the tail: "A kind of substance, like milk."
Upon further study, the team found that the milk contained lipids and sugars similar to mammalian milk. It was essentially providing the same function.
"It's a very unusual form of nutrition" for an egg-laying animal, says Mailho-Fontana.
Is it really milk? Well, that is up in the air for now, but it is a nutrition source for the babies provided by mom. For the full story as well as a link to the study, click here!
