Alien Profile: H’Nydron

The following article was submitted by John Hawkins as his entry to the Alien August competition. Thanks John.

The H’Nydron are a near sentient (think dolphins) species occupying the ocean planet Kepler-22b. They have the appearance of the unholy offspring of a dolphin, shark and octopus. They have three eyes providing 360 degree vision, one sees visible light, the remaining two use infrared. They benefit from a dense and methane rich atmosphere by shooting out of the water and taking flight. This is done to catch foolish Mowassi which fly too low to the ground, the Mowassi are essentially massive whales in the sky, filter feeding from jet black floating animal-plant hybrid Fendorms, which photosynthesise the planet’s Main sequence G type star’s light. The H’Nydron also take off to capture methane for use as fuel. They travel using the methane similarly to how a rocket works; a singular fin helps channel the expelled and combusted methane which allows the H’Nydron to stay in flight for several minutes before diving back down into the ocean.

H’Nydron mate in a trio, with a similar aspect to the common mammalian reproduction of Earth, except with a third partner requiring a vital enzyme. They live in small packs, with the females carrying their young in a pouch just below their bulbous head.

Their hunting method is for the strongest H’Nydron to pick a Mowassi and then the pack to viciously attack in, clawing off chunks of meat and consuming them while coming round for another attack. The method is brutal but effective, as they carcass falls, they follow it. By the time it hits the ocean, it has been stripped down and the pack is long gone.

    Wow! The concept of this seems very well thought out!

    How do you combustion work with methane in a methane atmosphere? Would not Oxygen be required ? and in a signifiant quantity mixed with Nitrogen (You know Gas Mixture required for combustion.. Or are we talking compressed gas?

    If the gas is stored in the fish, how do they dive? A balloon is not the best submersible. Compressed to a liquid? That is some serious cold….−179.5 °C meaning the fish would “fart” very long icicles and need some serious insulation and a pressure vessel and bop around the surface like a cork (pressurized vessel for gas)
    I know Physics are a a bitch.
