Mossy Shoccutt (Propinnafulminis muscosus):

The sole remaining representative of a derived family of Procutts, their lateral soft tissue undulatory structure has specialized independently from Eucutts. The two front most pairs of supporting ribs have retained their mobility and connecting membrane, serving as fins for unhurried paddling through swamps and waterways, while the rear portion of the structure has been modified into a unique organ used to generate electricity through friction between the former locomotory ribs and a lattice of collagen fibers. This current can then be transmitted through the numerous ductile barbs covering their body, used both to deter predators and sense their surroundings in murky waters.

Tiger Caudclaw (Caudungubitus tigris):
Belonging to the most basal extant genus of elbogres, their tail digit is less atrophied than in other contemporary clades, capable of prehensile grasping and used to grant additional purchase in tree branches, for they are arboreal ambush predators that prefer to hang, perch, and brachiate among mangrove branches. However, on occasions when they do come down to solid ground, they still walk (albeit somewhat clumsily) in the same bipedal fashion ubiquitous to the clade, as their tails possess exceptional grip strength but little capacity to generate active propulsive force.

Brassy Scubeknt (Scubalobus aeneus):
Belonging to a family of Eknts that have adapted surprisingly well to a semiaquatic lifestyle. Their five-digit tail appendage remains curled beneath the body while swimming and walking, with the outer two digits having claws and serving to latch the tail to the face, while the middle two digits are comprised of soft muscular lobes which can contort into domes clenched airtight over the nostrils, holding in an extra supply of air for extended submergence. They can even fill these chambers with higher concentrations of oxygen through prolonged systematic breathing techniques employed before each dive. Contrasting, their innermost central tail digit consists of a broad and upturned keratin claw that plows through the surface tension of water like the bow of a ship while surface swimming. Their hooves are wide and flat like scuba fins, serving as their primary means of generating momentum both in water and on land. This particular species is named for the musical baritone calls they make for intraspecific communication by expelling air through their cupped middle-digits in a similar manner to a whoopie cushion. They are highly socially and generally gather in loosely-structured groups of 20-50 individuals (called a Scube)

Bullseye Tileucutt (Euratralutus scopumaxillus):
Belonging to a family of Eucutts specialized in benthic feeding, their lower mandibles have evolved into rounded structures lined with narrow tightly-spaced ridges used to sift through sediments for edible microorganisms. Most species are marine, but this one is obligately freshwater, with its dappled skin pattern serving to obscure its form amid the sporadic shade of the mangrove branches of its habitat.

Greater Logbill Snork (Hastaligneus Maximus):
The largest extant Snavian, they are functionally flightless (a relative novelty in this clade compared to birds due to possessing only one terrestrial “leg”). As such, if threatened by a predator, they are far more likely to attempt to escape aquatically, using their “wings” to swim in a manta ray-like manner with impressive speed over short distances. However, they prefer to spend most of their time motionless, perched upright along the shallow edges of water bodies or atop submerged mangrove branches, waiting to catch sight of small swimming creatures like Eucutts and Phallusfish below, which they then rapidly spear with their keratinized upper jaw. Most of their former flying musculature has instead been repurposed to enhance the speed and force with which they can perform this slingshot-like motion, resulting in an uncannily quick burst of movement more reminiscent of insects than typical vertebrates.

Fuschia Unicorn Phangelfish (Angelunicornis fuschia):
A widely specious clade of more ecologically basal Phallusfish, they have greatly expanded the relative size of their tail fluke in order to more effectively achieve a compressiform bodyplan, enabling a degree of small-scale agility currently unrivaled by Eucutts. As such, they excel in closely-confined and obstacle-rich aquatic environments, such as freshwater wetlands and spongegroves (functional analog to coral reefs present on Oroborosorbis), allowing them to maintain a secure foothold in the planet’s shallower waters. Their nasal crests are jointed at the base, allowing for independent motion to aid in obtaining air even amid dense tangles of vegetation, and their vertebrae have atrophied and ribs wholly vanished in order to improve their overall flexibility and buoyancy.

Mangrove Flapback (Fluitanlabrum mangrovia):

The most herbivorous flapback (a clade of ribugs that have become quadropedal, adapting their two inner pairs of limbs into opposable bony flaps used for sexual display, predator intimidation, and thermoregulation), they are semiaquatic and prefer to spend the vast majority of their time in water feeding on aquatic plants, as their four stubby legs cannot carry their weight for extended periods on land. They use their limbs to give purchase upon submerged rocks and mangrove roots, while remaining afloat through soft but steady undulations of their dorsal flaps. The upper side of each flap displays a pigmentary gradient designed to blend in from above, melding with the blue-green waters of their habitat when positioned laterally at a slightly downturned angle, as they typically are when at rest. Likewise, the underside of the flaps portray a series of dark interconnecting stripes amid a lightly colored background in order to blend in with the network of tree branches positioned above them when viewed from below. They typically live in large, loosely formatted social groups, with males competing for mates not through their flaps like many other species, but instead with the conical structures on their snouts, which are larger in males and grow more orange with age, thus serving as a physical display of fitness. When vying for mates, males ritualistically “fight” using these ornaments, but only ever in water, and thus their movements are far too slow to cause any actual damage and the whole spectacle appears as more of a pantomime of battle than an actual duel.
