The "Stephasouras" lives in the photic zone (upper part of the ocean) where it's typically 24 to 104 degrees Farenheit. This area receives sunlight and the depth is a causation of how transparent the water is.
"Stephasouras" also lives in the neritic zone (seaward from low tide line, continental shelf out to the shelf break). Nertic zone receives a lot of sunlight which reaches about 50 meters down into the water.
Who could forget about the pelagic zone (beyond continental shift)?? "Stephasouras" can also be found there! A few abiotic factors of the pelagic zone include water, light, salinity, pressure, tides, waves , and exposure to air.
My organism is a blue-ish green color in order to camouflage into the water to hide from its prey which are phytoplankton, algae, and seagrass, and predators which are jellyfish and sea turtles.
