I took this photo in a zoo, but I still think it’s worth sharing. Keep an eye out for these snakes, if you’re a chicken owner like myself.

Is traditional Boidae (boas, pythons, Loxocemus, Casarea, etc.) monophyletic?

no, not at all. It's a shitshow.

Here is part of the phylogeny of squamates by Zheng & Wiens (2016).

True pythons (Pythonidae) are sister to Loxocemidae (burrowing pythons), in turn sister to Xenopeltidae (sunbeam snakes)

On the other hand, Boidae in the broad sense (since very often treated as superfamily Booidea, with subfamilies treated as full families) is closest related to Calabariidae (Calabar 'python'). The relationships between Pythonidae+Loxocemidae+Xenopeltidae and Booidea+Calabariidae is not well resolved, and the Xenophidiidae and Bolyeriidae somehow get in the middle.

So, it is very likely that pythons and boas arrived at their morphological similarities rather independently. Which is especially impressive in lineages like Chondropython and Corallus, which are just unbelievably similar.

For other ramblings on a related topic, see this post about the lack of pythons in Madagascar

Actually I got curious,

What exactly are the differences between pythons and boas?

Pythons and boas are two major snake families! They're both fairly primitive families, and are known for both being non-venomous and having the largest snakes in the world among their members! They tend to fill similar niches, but there are a lot of cool differences, too!

Pythonidae, the python family, are all non-venomous and are found across Africa, Asia, and Australia. They are exclusively oviparous (lay eggs). They share a lot of primitive characteristics with boas, including a rigid lower jaw, a vestigial pelvic girdle with hind limbs visible as spurs, and a semi-functional left lung.

Aside from their range, though, which is primarily in the Old World, pythons are distinguished from boas by an extra bone in their skulls and a few extra teeth. In addition, they almost always have heat pits and heavily rely on them for hunting, with only two species in one genus (Aspidites, the "pitless wonders") lacking heat pits.

Boidae, the boa family, are found primarily in the Americas, but also have a few species in Africa, Asia, Europe, and a few Pacific Islands. Unlike pythons, they're typically oviviparous and give birth to live young! Boas have a much wider range than pythons, and their ranges are almost entirely mutually exclusive - it's rare to find boas and pythons in the same habitats.

Boas also don't rely on heat pits nearly to the extent that pythons do, and many species don't have them at all. When boas do have heat pits, they're located beside the scales, not set into them like they are with pythons.

The Central African rock python (Python sebae) is a species of large snake in the family Pythonidae and one of the 10 living species in the genus Python, which is native throughout almost the whole of sub-Saharan Africa, from Senegal east to Ethiopia and Somalia and south to Namibia and South Africa and have become invasive in the florida everglades. Here they are found throughout a wide variety of habitats including including forest, wetlands, savanna, grassland, semidesert, and rocky areas. It is particularly associated with areas of permanent water, and is found on the edges of swamps, lakes, and rivers. They are a generally solitary non venomous species of constrictor which is known to feed upon fish, rodents, birds, monkeys, antelopes, bats, lizards, crocodiles, dogs, goats, sheep, pigs, jackals, hyenas, & big cats. On average Central African rock pythons reach around 9.8 to 16.4ft (3 to 5m) in length and 97 to 121 pounds (44 to 55kg) in weight, however individuals reaching up to 24.6ft (7.5m) and 214lbs (97kg) are not unheard of. African rock pythons have a relatively small, triangular head that is covered in irregular scales that are typically blackish to brownish-gray in color. The body is yellowish, gray-brown, or gray-green, with dark blotches that form a staircase-like pattern on the back. Belly scales are a white color with black specks producing a salt-and-peppery pattern. Mating occurs in the spring after which time the mother climbs inside an old animal burrow, termite mound, or cave and lay 20 to 100 hard-shelled, elongated eggs. The female shows a surprising level of maternal care not typical for snakes, coiling around the eggs, protecting them from predators, and possibly helping to incubate them, until they hatch around 90 days later. She then spends up to 2 weeks protecting and caring for the hatchlings. Under ideal conditions a central African rock python will reach sexual maturity at 3 to 5 years and live up to 30.

Ok so! About cruthe, what is his species called and does Ben have them in his Omnitrix?

Sorry this took a bit, as I've been a tad busy. But, Cruthe's species name is Pythonorid Corax. It's based off the words that inspired the design of the species, being Pythonidae, Corvus Corax, Florid.

Ben's version of this species has a half colored, half faded feathered fluff, as he's a "Glass half full" kinda guy. His clothes resembles that of a jester, a being of nobility and a musketeer. Ben's name for the transformation is, "Foltair" a play on the Philosopher Voltaire and air, as this species can glide for miles before they reach the ground again. It also happens to sound like "Float", which is also fitting for the species.

African rock python is a species of large constrictor snake in the family of Pythonidae. 

The species is native to Africa. It is one of 10 living species in the genus Python. Africa's largest snake and one of the eight largest snake species in the world 

African rock pythons have a thick body covered with colored blotches, often joining up in a broad, irregular stripe. Body markings vary between brown, olive, chestnut, and yellow, but fade to white on the underside.

The head of these snakes is triangular and marked on top with a dark brown “spear-head” outlined in buffy yellow.

African rock pythons are non-venomous and snakes they don’t have fangs.

The snake is widely feared, though it very rarely kills humans

African rock python’s lifespan is 20 – 30 years but the might live even longer in the wild.

You’ve probably heard that snakes have poor eyesight. This is true!

African rock pythons. They aren’t blind, but they don’t perceive much with their eyes; instead, they rely on a complex sensory organs in and around their face.

The tongues of African rock pythons are able to “smell” the surrounding environment. If a prey is nearby, their tongues will sense it.

African rock pythons have heat-sensing pits in their scales that

Helps them locate both predators and prey.

African rock pythons start to mate with each other when they’re around 3 – 5 years old.

African rock pythons are solitary creatures that prefer to live and hunt alone. The exception to this is the mating season; they’ll come together to breed, but it doesn’t last long, and males leave the females as soon as they start nesting.

African rock pythons are most active at night, especially when they’re trying to hunt.

Thonia - derived from Pythonidae, the scientific name for pythons 

Binari - Binary- as in, binary numbers 

Quite the homebody

Would rather spend time with computers than people

Sticks to routines
