"Polydactyls"

This is generic the name given to a variety of separate
“vertebrate” animal groups that are united by the presence of multiple digits on
their front and rear limbs. These digits are thought to be derived from the
multitudinous, centipede-like tube-limbs of even earlier “vertebrate” ancestors.
As the tube-like feet merged and bundled over the course of Snaiadi “vertebrate”
evolution, some took the role of fluid-filled hydraulic muscles, others became
bone-like support structures or degraded into more conventional fibrous muscles,
and yet others protruded from the tips of extremities like digits. As the
majority of large Snaiadi land animals have two digits per limb, a trend towards
reducing these digits and incorporating them inside the arms and legs must have
taken place as more “advanced vertebrates” evolved from Polydactyls or
Polydactyl-like ancestors.

Today, the different Polydactyl groups occupy a number of
low-key niches all over the planet. Although most of these are fairly small and
unremarkable animals, fossil evidence indicates that certain lineages, now
extinct, grew to megafaunal sizes far earlier in the planet’s natural history.
The unusual Turtiformes might also be Polydactyls.

Species: Telescopocephalus barani
Common Names: Whizzard,
Telescope Whipslider.
Size: 40-50 centimeters long excluding
tail.
Habitat: Rugose scrubland between the East Isternan plains and the
Great Isternan Pinnacle Range.

Telescopocephalus is one of the three thousand species
of widespread Whipsliders (Tunicasaurs) found all over Snaiad except Thalassia,
Aar and the Endland. In form as well as function these creatures can be
considered to be Snaiadi lizard-analogues, although several other lineages have
evolved similar body shapes and lifestyles on Snaiad. These animals come in a
variety of sizes and shapes, but all Tunicasaurs are characterized by the
presence of multiple toes, (although limbs are reduced in some groups,) long,
tentacle-like second heads and peculiar extensions of their hydraulic muscles
into their body walls, which allow them to wriggle through the undergrowth with
ease.

Telescopocephalus belongs to a sub-group of
Tunicasaurs called the Lygocephalans, also known as Stickheads. These animals
are usually active at day, and use their elongated, probe-like heads to break
into the nests of colonial Trikes. In night, they rest under pinnacles or
specially-dug burrows. Telescopocephalus is so far the largest
Lygocephalan known, with a body exceeding half a meter in size. Its long,
whip-like tail, usually twice as long, works as a predator-distracting lure and
in males, as an ornament of sexual competition.

Species: Toxoglossos hyigiani
Common Names: Bukalemun, Ridge
Chameleon.
Size: 20-25 centimeters long.
Habitat: Vesternian Pinnacle
Range and surrounding areas.

Classified by some researchers as Tunicasaurs and by others in
a group entirely of their own, the nine or ten species of Toxoglossos
show a remarkable convergent evolution with Flagelloglossid Jos and Chameleons
of Earth. They have a spring-like, hyper-extensible second head which they use
to “zap” their arboreal prey. Unlike Jos, but like Earthly Chameleons, they also
have a form of active camouflage and social display under their skin, but with
Toxoglossoans this means a shape-changing ability rather than a color-changing
one. Muscular extensions of their skin, running along their back, flanks and
vents, have the ability to “pinch out” and mold themselves to a variety of
silhouette-breaking shapes. Since numerous Snaiadi predators seem to be
color-blind, it is thought that a shape-shifting ability has been more useful
than a color-changing one in the hectic world of the pinnacle ranges. These
animals move in a very unusual, inchworm-like fashion, grasping branches with
one pair of legs and reaching out with the other.

Species: Fergulia fossoria
Common Name: Chunker.
Size: 20
to 40 centimeters long
Habitat: Plains and sprogland in Lower Vesterna.

Probably the closest Polydactyls group to the well-known
Turtiformes, the little-known Ferguliids are an obscure lineage adapted
extensively for digging and herbivory. They have ridiculously muscular second
heads for their size, similar (but not related) to those of the great
herbivores. These organs are furnished with plant-grinding surfaces and circular
“chewing” muscles that run around their circumferences, and can cope with any
plant material, hard or soft, green or red.

Ferguliids burrow underground, but mostly in sprog, continually
eating as they burrow. In some cases, they have been documented to “eat their
way” into the upper stories of dense tree pinnacles at pinnacle ranges.

Species: Platymoloch tubifex.
Common Names: Flapjack, Eyed
Flapjack.
Size: 30-40 centimeters, usually less.
Habitat: River Sambatyon
and other fresh-water bodies in Oroland, related species present on south
Isternan coasts.

The sub-continent of Oroland, isolated as an island for most of
its geological history, still houses numerous groups of unique animals. Among
them are the Tubibrachids, unusual Polydactyls adapted extensively to a
freshwater existence. Flattened along river or pond bottoms, these animals’
entire lives are spent underwater, although they can hibernate under mud or
manage a pitiful crawl on land if waters dry up. Unique among Snaiadi
vertebrates, these animals have tube-like snorkels extending out from their
“armpits,” connecting to the lungs inside. Thanks to these organs, Tubibrachids
do not even need to surface for breathing, although even the snorkels are seldom
used because they absorb the majority of their aquatic oxygen directly from
their guts, “inhaled” by their second-heads.

Tubibrachids like Platymoloch are peaceful creatures,
dragging their flattened second heads hoover-like across the bottom sediment to
scoop up any small animals, plants or organic detritus. Although they are not
very active, they can swim away in a surprisingly fast, “waving” motion if
danger threatens. These animals can survive for very long, and are also one of
the “living fossils” of Snaiad. Eighty million year old fossil Tubibrachids like
Echinodesmus and Platytitanis are not much different from
their contemporary descendants, except perhaps in their size.

Species: Cryptodactylus ammophis
Common Name: No common
name.
Size: Up to 18 centimeters long.
Habitat: Beneath sand dunes or
steppe-soil in central Thalassia.

Cryptodactylus shows the unusually
common example of “snaking;” the reduction of arms and legs that has happened
countless times in widely different Snaiadi animal groups. By itself
Cryptodactylus is a little known and probably boring creature, digging
tunnels under sandy soil to hunt burrowers like itself. However, this animal’s
identity as a Polydactyl, as shown by the scale-like fingers and toes embedded
in its body wall, bears witness to the enormous diversity and old age of this
group. Present on every continent on Snaiad, Polydactyls must have diversified
very early on in the planet’s history.

Cryptodactylus belongs to a unique group of
burrowing, legless Polydactyls (Punctatophids,) found only on Thalassia. Some
species are very abundant and are staple foods for the various species of
Mikados.
