SC.2023.35. Black Maskfish
"Dratted, we're in here for a while, it seems."
"Yeah, we're overflying... Oh, look!"
"What am I looking at?"
"That pod of maskfish, with two young..."
A long, sleek, muscular cetacean reaching up to 7m to 9 in length and up to 7 tons in mass, it is the ocean's apex predator.
Forming packs capable of hunting to destruction almost anything, up to ships, these leave devastation in their wake, when they are hungry or otherwise aggressive.
The main difference, other than size and bulk, between a silver maskfish and a black maskfish, is the colour, the darker shade perfectly adapted to the nocturnal habits of the black maskfish.
Dietary Needs and Habits
DietCapable of hunting anything in the water it sets its mind to, it's known to favour large aquatic mammals, such as , and .Giant Sea Otters.
Considered Sapient by most experts, the adults engage in play with their young, and will use tools, not unlike their cousins, the silver maskfish.
Capable of communication using frequencies as low as 10 hertz, and as high as 100kHz, they display rare mastery of sound, especially under water, although they can breathe air, and can come out for short periods, provided it's not long enough for their skin to become too dry.
One behaviour that's of particular note to researchers: they've been known to make jokes, and sometimes will pass gas to punctuate jokes. While experts are not convinced, a few psychologists believe they do so to mark 'dad' jokes, or 'puns' or otherwise low-brow humor.
Perception and Sensory Capabilities
One of the sharpest echolocators on Arnd, this huge predator uses infrasound and ultrasound to echolocate prey, the lower frequences at longer ranges to detect the general direction of prey, and to communicate amongst themselves, and the higher frequencies at close range, giving the prey little chance to escape.
