Description

A female Greater Lavlin has just dug a hole for its eggs to be laid in, which has caught the attention of a beach-side predator, a Sand Rask. The mother is moments away from shooing away the intruder with a series of aggressive calls and charging at it. However, the Lavlin itself is at a great danger, being awkward and ungainly on land, and being susceptible to beachside predators larger than it, such as falkrites .

65 myh, the oceans of the world have experienced a complete transformation of aquatic tetrapods from the Holocene. Long gone are most of the whales, sea turtles, and manatees. Instead, a whole new breed of swimming organisms emerged.

Penguins, while losing a good number of species, was able to overcome the massive loss of polar fauna in the Holocene. With a lack of competition, they expanded into increasingly aquatic niches, such as the Megalournis, which took on a more seal-like niche. Once the cycle of ice ages came to a close, the earliest members of a new group of birds known as Supraviles emerged. They are characterized for being incredibly large aquatic birds, and are found over all the world's oceans (And even in a few river systems).

To become such successful aquatic birds, they had to make sacrifices. First, almost no members of the group take care of their young. For a seafaring beast, coming to land and investing the time into caring for multiple chicks took up too much time. So, they evolved a more sea turtle-like method of reproduction, laying a good deal of eggs and hoping that a few survive. They are also a highly sexually dimorphic clade. Since males no longer have to venture onto land to mate with females, they are much larger than their opposing gender. Additionally, males legs are much more paddle-like, which is also due to not having a need to venture onto land. Females almost always have simple webbing, rarely having anything more.

Supraviles are derived from penguins inhabiting warmer climates, as nearly all polar species died out with the massive global warming at the start of the Ortugene. They originally were just simple piscivorous open water swimmers, but have since expanded into many niches. These include cold-climate filter feeders, freshwater ambush predators, and incredibly ferocious ocean predators. They can be seen around coastlines of every continent.

They are divided into 2 families, Crassqiuds and Eriolids.

Glabbiuds have replaced their ancestors feathering for blubber, and are especially common in polar regions. They do not entirely lack feathers, though, as all members have whiskers near their beak.

Eriolids have kept their ancestor's feathering. They are more common in warmer areas near the equator.

Shown Species:
Greater Lavlin (Gracihalavis major)
The Greater Lavline belongs to a genus of carnivorous migratory eriolids. They are among the largest of all the species, with males at 8 feet long and females at 6 feet long. Their coloration evolved as an effective means of camouflage in the water, like many marine creatures before them. They, along with their relatives, can be found over much of the Southern hemisphere, though this particular species is seen mostly around Antarctica and South America.

Their diet consists of fish and other aquatic animals. Females will typically lay their eggs either on Antarctic shores or on South American shores, near what once was Chile. Their migration typically consists of moving North, towards the equator for the colder months, and moving back South again once summer arrives. Young typically spend their first few months near shore before heading out to open waters.

Sand Rask (Curviostravis arenicolus)
This bird is the descendant of shorebirds that have inhabited Anarctica since as early as 16 myh. It has long legs, being adapted to quick pursuit on the beach. Their coloring is due partly to being a good camouflage on the Antarctic beaches, matching the sandy shores. They have evolved elongated beaks used to pry food from the sand or the water.

Their diet is incredibly lenient, as it encompasses shellfish, mollusks, fish, birds eggs, carrion, and almost anything else they can fit in their mouths. They roost on the ground, building crude nests of stones and sticks. While it isn't common, adults cannibalizing on children can occur, especially in areas with bad conditions. Young become independant fairly early on, leaving their mother after just a few months.
