Thalduuth Anatomy
Once one of the largest species on Rudicus, reaching lengths of 35 meters and weighing up to 400 tons. They would've existed over 230 millions years ago, during an ice age. They swam through open arctic seas, using their spindly mouth-arm to vacuum small fish, plankton, algae, and any other small species. A handful of remains have been found frozen within icebergs and glaciers, retaining many details lost with fossilization. They had glistening silver scales on their fin tips, and above their eyes. Most likely used for mating, intimidation, or communication. They also had a long beak-like rostrum that ends with silver, some have theorized that thalduuth many have sparred by ramming their rostrums into one another, like jousting. Thalduuth remains have shown signs of deep bone scarring, possibly due to these theoretical jousting sessions. Another intriguing tool thalduuth had are incredibly dexterous fingers at the end of their pectoral fins. These thin fingers have multiple joints, allowing them to bend in extreme ways to grab, manipulate, and inspect items. Whether or not they had any tool-use in their history is unknown, although it wouldn't be shocking. They most likely were the most intelligent species on Rudicus, having a massive brain, weighing about 2 tons. Composed of highly condensed neurons and brain matter, although their intelligence may have been one of a different type, at least to humans. Some have hypothesized that thalduuth may have had some form of telekinesis. An outlandish thought at first, until you consider that telekinesis has appeared in the evolutionary history of Rudicus at least twice before. Once in trilotaze, crustaceans that can seemingly latch onto objects with impossible strength, and duo dii maris. Duo dii maris are massive leviathans that still exist, and are capable of shifting large icebergs without touching them to avoid damaging their delicate sails when breaching. Quite the evolutionary oddity.
