Here are some ideas I had:
Ancestor: Nautilus
Name: Shell Kraken
Description: This type of nautilus grows to be very large by changing its food type to small creatures like Copepod and Diatoms. Because of this diet change it is also grown for protection. Their arms have become more effective at filtering
Ancestor: Yawunik
Name: False anomolocaris
Description: They began to specialize in speed in order to escape madmen, and for this they opened up some of the fins to larger ones, so that they were similar in motion to anomolocaris, but they began to consume small creatures that they could catch.
Ancestor: Kiwi Bird
Name: Niddlerd
Description: This kiwi species has developed a larger body and strong legs for being threatening against predators. They are now more similar to the cassowary, but thanks to their large and long developed beak, they are able to stab and pick up small creatures like aphids.
Ancestor: Candy striped hermit crabs
Name: Nautilied Scavenger crabs
Description: This species of hermit crab has begun to specialize in finding the only type of conch that exists on this planet: the Nautilus conch, which unlike those that normally do on Earth, is more compressed in the abdomen so that they can be compressed into this conch. To make it easier for them to squeeze in there, their hind legs became stronger for breaking the layers that separate the conch, allowing them to maintain this conch for the rest of their lives instead of finding new ones.
Ancestor: Copepod
Name: Copeclock
Description: They look like their ancestors, but in order to survive in this world, they began to roam in more difficult places and began to eat marine snow in the depths in order to survive, contributing to the carbon cycle and also serving as a food source for the depths.
Ancestor: Cave Aphids
Name: Jump Aphids
Description: Because of a missing niche in the tropics, they began to develop back traits that resembled âEarthâ aphids: sucking tree trunks and plants. But unlike them, their legs have grown a little more to help move in the ground and also to adjust to a jump, similar to a grasshopper.
Ancestor: Poison Carpet
Name: Clamer Capet
Description: In tropical areas where there is not enough light in the soil, they began to grow on tree trunks in order to reach better light sources, making the forests tangled in the shape of âvinesâ.
Ancestor: Chameleon
Name: Snappers
Description: A species much larger than its ancestors that roams the forests and uses its large tongue to catch fruits that is usually difficult to reach, similar to the trunk of elephants. They use the color change to communicate and to threaten predators
Ancestor: Waving Stars
Name: Radio arms
Description: This species began to bury objects in the sands and expose only their arms to mimic prey that would come close to being caught similar to a trap. They began to move less to the association of their ancestors.
Ancestor: Shoebill
Name: Beakrunner
Description: A species of Shoebill that started running in the savannah to hunt for armadillos and uses its source to get them out of the burrows and break their armor, allows them to obtain food that is usually hard to find there.
Ancestor: Rhino
Name: Dandroms
Description: A smaller species of rhino that has begun to graze in wide fields, similar to the water buffalo, and uses their numbers and large horns to drive away predators that can harm them.
Ancestor: Clouded Leopard
Name: Leopuma
Description: This species is part of being bigger and living in herds like lions for hunting prey that is hard to kill. They behave similarly to lions except for no permanent leader, whose hierarchy is more like wolves.
Ancestor: Crested Groshawk
Name: Skyvalhawk
Description: This large species began to specialize in finding bodies instead of hunting others, turning it into scavenger food. Thanks to this they have become larger, but because bodies are hard to find, they are also excellent at storing nutrients, though limited.
I think I exaggerated in quantity, but I had some ideas about it. Sorry if anything I broke one or two things.
