Scillid

Possessing an intelligence just below that of the old Terran dolphin, scillids of Castor are very large saltwater fish, averaging 7-8 feet in length and weighing 100-150 lbs. Scillids are socially much like dolphins, very family-oriented and an inordinate amount of their time is devoted to prey. For many centuries, scillids defied the most dedicated of Castori researchers with the mystery of how they sustain themselves with no identifiable stomach nor digestive tract; a mere 300 years ago, an oceanographer with the Ursiniru Zoological Center by the name of Rykinlin became obsessed with solving the mystery and ended up committing 24 years to finally discovering the answer: the scillids actually absorb dissolved nutrients from ocean water directly into their bloodstream. This astounding discovery was heavily debated, though Rykinlin's research was very thorough and his results very clear; it wasn't until 20 years after Rykinlin passed on from old age that his research became widely accepted as no alternative theories could be proven. Their unusual means of sustaining themselves makes it debatable whether scillids can even be classified as members of the animal kingdom. Rykinlin's research on the scillids inspired a the hydroextractive mining plant, in floating or neutrally-buoyant configurations, named in his honor as Rykinlin extractors. Rykinlin plants precipitate minerals directly from ocean water with very low energy requirements, similar to the scillid, with the added benefits they also precipitate out harmful toxins as well, actually cleaning the ocean as they operate.
