Irridalli by Abiogenisis Irridalli by Abiogenisis

The Irridalli are a successful group of medium-sized predators stalking the upper levels of Chriirah’s tropical oceans. Like many mobile quadrilaterians, evolution has optimised their four-sided body plan into a sleek, secondarily bilaterally symmetrical shape able to move swiftly and efficiently through the ocean.

Possessing some social intelligence, Irridalli travel in loose pods to locate swarms of suitable food, at which time they separate and attempt to drive the prey nearer the surface, thus rendering them easier to capture. Despite this initial co-operation, the actual hunt itself is performed independently of the other pod members, cooperation only resuming when prey needs to be driven towards the surface once again.

While Irridalli are quite fast, many prey species are considerably faster and swimming speed is not their primary weapon: Moving in behind prey, the large eyes fix on a target and when in range two tentacles launch outwards as an elongated and lethally barbed lower jaw attempts to impale it. If the strike is successful, the tentacles rapidly coil around the doomed creature and draw it towards the mouth.

Like most apex predators, the Irridalli suffered major population depletion in the period leading up to, and during, the fall of birrin civilisation. As the birrin recovered, so too Irridalli populations increased in parts of their former ranges as prey species returned. The loss of genetic diversity however has resulted in higher than expected parasite loads in some pods.

Once hunted by the birrin as food, they are now rarely eaten both because they are widely protected, and are so infused with accumulated industrial poisons they are mildly toxic to ingest.

This gave me a cool idea, a birrin surfing or somkind of surfbord of bodyboard and somthing looking up at it like some kind of shark/squid thing ready to snatch the poor sod, it would be cool to see more fauna from chiirah, maybe some kind of savannah type place....ohhh birrin safari!

This (along with so many other images in your gallery) is so realistic and aesthetically pleasing. The creatures have such a cool design! Beautiful composition.

These guys seem pretty lethal, i like their relation to whales on earth, in the sense of their co-operative and intellectual capabilities. Yet they seem to be quite an improvement aesthetically as the irridalli seem to be much more efficient even while leaning towards being independent organisms. I wonder if they are rivalled by anything in the oceans?

Two questions for your amazingness-
   If you don't mind the Earthly terminology, what taxonomic group does the Basketworm-derived stock correlate to? Is it a phylum, kingdom, etc?
   And second, do any other "stocks" exist on the planet?

Thanks you for producing such fine work. You truly are a diamond in the rough!

:iconabiogenisis:
Abiogenisis Featured By Owner Jan 26, 2015  Professional Digital Artist
Definitely lower than kingdom. More like a basal member of the polychaetes on earth, if they went on to become much larger and more complex.

Lots of other stocks exist, just never have time to draw them!

So apparently Birrin civilisation has collapsed at least once in the past, tell me more about that.
