Sputtlefish

The Sputtlefish is an aquatic species of fish-like creature that was discovered by Captain Charlie during his expedition on PNF-404. It can only be found underwater, incapable of traveling on land, and after recent studies is shown to share a symbiotic relationship with an alien form of Zooxanthella.

Appearance
This aquatic creature has a vague resemblance of Earth invertebrates, namely that of the Cuttlefish which its name is based off of. It lacks pectoral and dorsal fins that make up true fish, but keeps its stability during swimming thanks to its long tentacles that extend off the side of its head just in front of the eyes. Their main bodies are encased in a transparent skin layer, giving the illusion that its body is that of a underwater bubble. Despite this, it is surprisingly durable.

Interestingly, the ends of each tentacle resemble that of a leaf, and its back tail fins extend and encircle into the shape of a purple flower, each "petal" with butterfly-like markings on it. As this trait is often used by Pikmin, Skitter Leafs, and Creeping Chrysanthemums as a form of disguise, it is theorized that the same idea is implied to the Sputtlefish, as it often swims close to the surface and at risk of aerial predators as well as aquatic ones.

Behavior
Sputtlefish are placed in lower-tiers of the food chain: hunting small prey but are often prey themselves. They swim slowly in the water, and once coming across a suitable food source, it uses its tentacles to scoop up its prey and swallows them whole within its tube-like mouth.

Although a predator in its own right, it does have its own form of defense against larger predators. Outside of the flora-like disguise it possesses, it will also squirt out a cloud of ink as a means for a quick getaway against underwater predators.
