Averan

Averan is a planet part of our solar system close to Earth, our planet. This planet was once lifeless, but in about 300 million years ago, some aliens of some sort have terraformed this planet and used time travel to introduced many modern species of plants, insects, arachnids, small fish, small amphibians, and small reptiles, but the most important species of this planet are the birds (hence the planet's name), which were also brought to this planet. In about 300 million years later, many of the introduced species in this planet have diversified into many different variety of species, with many (not all) species looking very different to the ones from Earth.

Shape & Size
Averan is similar in shape to Earth, but can be distinguished from Earth because Averan has just one big supercontinent known as Pangaea Jr, due to its similarity to Earth's historic Pangaea from Permian to Triassic. It is also much bigger than Earth, being almost 3 times bigger than Earth. Because of this, more animal and plant life exists in Averan.

Geography
Averan mostly consists of oceans, as for the land, it mostly contains deserts, scrublands, savannas (tropical grasslands), (temperate/boreal) grasslands, swamps, marshes, boreal forests, temperate forests, subtropical forests, tropical rainforests, and non-rainforest jungles, but with the southernmost part of the continent consisting a vast tundra.

Plants

 * Grass - Nothing much is changed, other than they have diversified due to no trees in this planet, allowing grass to evolve into variety of species of grasses, ranging from the size of a common grass of cities to the size of of a conifer tree.


 * Carnivorous Flower Mimic - Descended from venus flytraps introduced to Averan by time-traveling aliens. They resemble a common dandelion, but with a predatory plant's "teeth" and an ability to hunt insects and other small animals. Due to its flower-like appearances, this makes makes them very attractive to their prey.

Invertebrates

 * Beetles - Most species of beetles, from dung beetles, to stag beetles, to rhinoceros beetles, to water beetles, to scarab beetles, have remained unchanged from their ancestors that were brought to this planet, but due to lack of bees, some species of beetles have evolved into honey beetles to fill the similar niche to Earth's bees, having the ability to pollinate flower-like grass descendants.


 * Spiders - Most non-deadly spider species, from daddy longlegs, to tarantulas, to orb-weaver spiders, have remained mostly unchanged from their ancestors that were introduced to this planet by time-traveling aliens, but some filled the niche similar to Earth's deadly spiders like black widows.


 * Crustaceans - Most species of crustaceans, including crabs, lobsters, crayfishes, shrimps, and krills, have remained mostly unchanged from their Earth-dwelling ancestors.

Fish

 * Modern-Styled Fish - Almost all species of modern fish brought to this planet still exist.


 * Giant False Whale - Descended from oceanic catfishes that were brought to this planet. Due to lack of their natural predators and lack of competition, they grew to gigantic proportions and filled a similar niche to Earth's baleen whales by evolving their whiskers into baleen-like stuctures to sip out krills. They are also the largest whalefish and the largest natural animals of our universe, about 500 feet long and weighs about 350 tons, due to the planet being much bigger than Earth, allowing animals of this planet to get larger than ones on Earth.


 * Great Whale Fish - Descended from oceanic catfishes that were brought to this planet. Due to lack of their natural predators and lack of competition, they grew to gigantic proportions and filled a similar niche to Earth's baleen whales by evolving their whiskers into baleen-like stuctures to sip out krills. They can grow to about 370 feet long and weigh about 210 tons.

Due to lack of their natural predators and lack of competition, they grew to gigantic proportions and filled a similar niche to Earth's baleen whales by evolving their whiskers into baleen-like stuctures to sip out krills. 220 feet long and weigh about 160 tons.


 * Lesser Whale Fish - Descended from oceanic catfishes that were brought to this planet. Due to lack of their natural predators and lack of competition, they grew to gigantic proportions and filled a similar niche to Earth's baleen whales by evolving their whiskers into baleen-like stuctures to sip out krills. They can grow to about 130 feet long and weigh about 95 tons.


 * Darwin's Whale Fish - Descended from oceanic catfishes that were brought to this planet. Due to lack of their natural predators and lack of competition, they grew to gigantic proportions and filled a similar niche to Earth's baleen whales by evolving their whiskers into baleen-like stuctures to sip out krills. They can grow to about 100 feet long and weigh about 90 tons.


 * Pygmy Whale Fish - Descended from oceanic catfishes that were brought to this planet. Due to lack of their natural predators and lack of competition, they grew to gigantic proportions and filled a similar niche to Earth's baleen whales by evolving their whiskers into baleen-like stuctures to sip out krills. They can grow to about 60 feet and weigh about 55 tons.


 * Dwarf Whale Fish - Descended from oceanic catfishes that were brought to this planet. Due to lack of their natural predators and lack of competition, they grew to gigantic proportions and filled a similar niche to Earth's baleen whales by evolving their whiskers into baleen-like stuctures to sip out krills. They can grow to about 25 feet long and weigh about 24 tons, making them the smallest whale fish species.
