EVOLUTION ATTEMPTS: Poison- 6+.5= (rounded down to) 6, Sting- 2+1.5=3, Armour- 3, Speed- 1, Senses- 3
(lol, seems that the dice gods mock your feeble attempts to become mobile)
The newest variety of the tentablob is the Devil's thornvine. They have developed enzymes and toxins on the ends of their tentacles, with a spine on the end, although said spine is fairly soft and (like a monitor lizard) only lets poison leak into the victim. Luckily, the aciblob's descendants are still relatively pierceable, so it gets the job done. The inner surfaces of the tentacles take in water, pass them through basic chemical detectors, absorb useful oxygen (nutrition is now done by the more toxic areas on the other side) and expel it again. This simple system lets the thornvine get a basic reading on the location of predators or prey, so it can have a certain direction to attack. Aciblobs are already learning to turn the other way when they get a whiff of the poisons. Other species, though, have begun to parasitise the other blobs. A tough outer skin helps fend them off (although it only works occasionally). Their climbing abilities are basically gone, as this new lifestyle means they can simply eat things that would otherwise overgrow them.
Parasiblobs are drifting on the currents. Aciblobs are developing better senses, and some of these more mobile aciblobs are reverting to a filter-feeding lifestyle. This time, though, they drift on the currents like jellyfish. Our reaction time is far too slow to catch them.
GENERATION 3:
Devil's thornvine
A deep purple cnidarian-like animal that is often found in depressions in the reef, due to their supplements of live meat. Their long tentacles take food from the water, for the most part. They grow up to 35 centimetres tall, and their offspring are called tentaclets.
REPRODUCTION: It lets out male cells in the current, and growths grow on the bases of the tentacles. These growths eventually become tentaclets, tiny parachute-like organisms that drift on the current to a better location.
MOVEMENT: Nope.
EATING: It absorbs cells that are drifting on the current, and any blobs that get close enough for a reasonable amount of time are impaled and digested.
PREDATION: The current apex predator. Ground-living blobs are what it eats.
COMPETITION: Thornvines still have little competition, even amongst themselves, due to their size and reproductive system.
ENVIRONMENT: A shallow sub-tropical sea. Layers upon layers of various types of blobs have built massive networks of reefs. Tentablobs grow above the rest, filtering food from the open water, while the thornvine dominates where it grows. Aciblobs, 3 or so centimetres wide, create open space and crevices through their tireless grazing.
