Gelapsi

The Gelapsi (gel-app-see) are an alien species of gelatinous psychic serpent-folk. Their large bodies are comprised entirely of a semi-liquid 'neural gel,' granting them remarkable intelligence and a natural aptitude for psychic abilities.

They are commonly very tall (8-10 ft), with lengthy tails too. thicker than their upper bodies and anywhere from 60- 120 ft long on average. They also possess two sets of antennae. The frontal antennae are delicate to the touch, and function as auditory receptors. The larger rear antennae are less touch-sensitive (in fact notably soft and squishy to the touch), and act as feelers for a psychic sixth sense the Gelapsi call the 'Mindstream - a flow of psionic energy that surrounds all things. Their auxiliary 'eyes,' while incapable of visually processing light, allow them to see the Mindstream overlaid on their more traditional spectrum of vision.

Gelapsi are cold-blooded lifeforms, becoming mildly tired and lethargic in temperatures under 40 degrees C. As well as possessing remarkably keen minds, they also exhibit impressive physical strength, Lacking muscle structures, their gelatinous bodies move entirely by psychokinetic impulses in their neural gel, it would be accurate to say their physical strength level is directly related to their force of will.

The Gelapsi that found your spacecraft was kind of in a horny mood, and curious on how edible new creatures are.
