EVOLUTION ATTEMPTS: Memory/Learning- 3+2=5, Scissor-claws- 3+2=5, Better wings- 1+2=3, Walk on wings- 4, Contact sex- 5, Buried hive- 1
The common slicer is an aerial animal, not particularly specialised. It uses its wings to walk with, aiding its two legs, giving it a grand total of six walking limbs. Its bottom two tentacles have developed into ferocious-looking shears, that can slice through the flesh of its prey with ease. Its most interesting characteristic (apart from its ability to mate without having to spawn in the water) is its ability to memorise useful techniques it uses or copies. This has given it a simple cultural evolution, where different populations of the outwardly-same species specialise in different prey, like orcas do on our planet.
Hives are still underwater, but have projected their upper surface above the water, letting us land on them. The bad side of this is that it is now open to air-based parasites. The guidelings are still expert gliders, and can still easily find their way back to the hive. The cattle caste, however, is now able to produce fatty globs from its mouth, so it can continue to grow without having to be eaten.
Leggedgrinders of various shapes and sizes are beginning to dominate the environment. There are no herbivores yet, but the spearfaced worms have shrunk.
GENERATION 19:
Common slicer
A grey bird-like animal that hunts around the greenplains. They use their fanged tentacles to attack and kill their prey. They can fly. They grow up to 40 centimetres long, and their offspring are called tentaclets. They use two claws on their back to snatch prey from the ground or air.
SENSES: It has a sense of touch that lets it figure out if it's touching food, and an extremely good sense of smell/taste. Symbiotic guidelings help it find live prey. A keen electrical sense lets it find creatures that are close to it, and it can feel vibrations from moving creatures. Its hearing is superb, and it can echolocate.
REPRODUCTION: It 'kisses' a mate it approves of, passing male cells to it, and growths grow inside of the womb. Tentaclets follow their mother until they can be dropped off at their hive. They eat mucus that the hive creates and, when they are large enough, find a suitable guideling to make a nest with.
MOVEMENT: They fly by using their large pectoral fins as wings and their thorachic fins as engines. They have two legs on their underside.
EATING: It impales small animals and digests them by drawing them into the guts. They are able to prey on fast swimmers, and they use venom. Most of their food is from grazing worms and the dense vegetation. Other prey include land-dwelling spearfaced worms (slitherers) and other flappers. We can use a precise jet of neurotoxin to poison prey.
PREDATION: We are mostly unpredated on the land.
COMPETITION: Most populations don't compete with the native predators.
ENVIRONMENT: A lush plain of greenweed surrounding the lake and river.
HOME TERRITORY: Greenweed plain
NEARBY ENVIRONMENTS: Near-barren mountain, Rocky shore, Cool uplands
