A Mysterious Predator, Endemic to Madagascar.

-

Greetings. Cryptoprocta ferox, known as the fossa, is a mysterious mammal that has challenged scientists ever since it was first described back in 1833. The largest mammalian predator on the island of Madagascar, the fossa has physical characteristics that are reminiscent of some species of felines, but the species is not related to cats at all. 

Often described as looking similar to a small cougar, fossas are somewhat of a mystery, from taxonomic and evolutionary standpoints. Fossil evidence shows that the species' ancestors appeared on Madagascar approximately 20 million years ago, during the Miocene. An extinct species, Cryptoprocta spelea, which was twice as large as the modern fossa, disappeared around the year 1400. Genetic research has suggested that the species is related to veverrids, and not related to cats, dogs, or other similar mammals, despite their outward appearance. 

The species is widespread across Madagascar, although in relatively low numbers, which makes the species vulnerable to extinction. Fossas prefer heavily forested habitats, and hunt during all hours of the day or night. Their diet consists of birds, lemurs, lizards, rodents, and tenrecs. A medium-sized predator, adults reach lengths of about 80 centimeters with weights of 9 kilograms common. Males of the species are usually a bit larger than females, with both sexes having semi-retractable claws, powerful limbs, and highly flexible ankles which allow the animals to effectively operate on the ground as well as in forest canopies. The species has a mongoose-like head, a short muzzle, small rounded ears, and a long, muscular tail that takes up almost half of the animal's overall length. 

The species' flexible ankles afford the animals a wide range of arboreal movements, including hanging upside down by their hindfeet from low-hanging tree branches. Fossas are highly adaptable to different elevations, ranging from 440 meters up to approximately 2,000 meters above sea level. The activities of human beings has placed the species under some pressure, due to the removal of 80% of the forest habitats on Madagascar. (Percentage as of 2023.) Since deforestation efforts on the island are continuing unabated, the future of the species is uncertain at best. 

The extinction of the fossa would be loss for us all, and for the planet's biodiversity.

Thank you for your time and consideration

Ufological Pushback Against the Scientific Method and its Proponents? A Hypocritical Course of Action.

Greetings. Why is a data-driven, skeptical, dispassionate approach to the UFO problem viewed in such a negative light by some in the UFO subculture?  Why does the application of the scientific method garner such consistent pushback from some in the UFO subculture? While there have been some historical examples of credentialed scientists taking a look at the UFO problem, such occurrences are relatively rare, and certainly not the norm. The UFO phenomenon and its attached subculture, have always been viewed in a negative light by the greater scientific research community. The fault for some of that reasoning lies squarely at the feet of the UFO subculture itself, with its tinfoil hat, costume wearing adherents, and its penchant for embracing the "woo" and other beliefs and mythologies that are "grounded" in faith and not supported by any irrefutable evidence whatsoever.  Has the situation changed to any substantial degree over the decades? I believe it has, but only b...

Doubt, Reason, and Free Inquiry, Not to be Tolerated in the UFO Subculture.

Greetings. The belief in unidentified flying objects is passionate, beyond what the English language can adequately describe.  The situation has progressed to the point that many aspects of ufological belief structures strongly resemble religious belief structures, complete with their own set of prophets (Bob Lazar, George Knapp, Jeremy Corbell, Luis Elizondo,) mythologies (Aztec, Aurora, Trinity, Kingman, Maury Island, etc.,) and even a day of deliverance (disclosure.) "A subtle thought that is in error may yet give rise to fruitful inquiry that can establish truths of great value." Isaac Asimov (1920-1992) Some people who claim to have personally experienced the UFO phenomenon have become close-minded, intolerant of being questioned, often responding with rhetoric that speaks for itself, childish in wording, occasionally hateful, embarrassing to be honest, obviously counterproductive. The unfortunate result of this is that UFO investigators have become handcuffed, unable to...

Too High of a Standard UFO Faithful? Don't Cry.

Greetings UFO believers.  "Extraordinary claims require extraordinary evidence."  The Sagan standard is one of the most vilified razors in today's UFO subculture. First used by Carl Sagan during the PBS television program "Cosmos" back in 1980, and in his 1979 book "Broca's Brain," the aphorism is seen as being essential to the scientific method and highly descriptive of the demands of scientific skepticism. Historical figures from Thomas Jefferson, Theodore Flournoy, Marcello Truzzi, to Pierre-Simon Laplace made similar statements during their distinguished lifetimes, but Sagan is the individual most often associated with the formulation.  As it pertains to the UFO problem, Sagan's statement is often (always) cast aside as being unreasonable, or too harshly skeptical, but is it? The possibilities of alien visitation, multidimensional visitors, or time travelers coming to the Earth are quite extraordinary to consider, so why is the necessity fo...
