Planet Profile

• Planet type: super-Earth, probably rocky
• Host star: M-type red dwarf
• Mass: 1.25 Earth masses
• Radius: 1.073 Earth radii
• Orbital period: 37.4 days
• Orbital distance: 0.1633 AU
• Located in the habitable zone of its system

Environment

• Gravity: slightly above Earth
• Atmosphere: unknown
• Surface: rocky, possibly ocean-bearing
• Climate: temperate if atmosphere exists
• Light: red-dwarf spectrum

Creature Design Direction

Moderate-gravity shoreline or marsh life, amphibious, compact, adapted to red light.

Planet / Habitat Depicted

A compact amphibious shoreline animal walks through shallow tidal flats and damp mineral sand under muted red-dwarf light, with water displacement, wet footprints, low marsh-like growths, atmospheric haze, and a broad rocky coast visible behind it.

Final Prompt Used

Create a scientifically plausible alien creature from TOI-700 d.
A shoreline alien from TOI-700 d, a rocky habitable-zone exoplanet around a red dwarf, compact amphibious body, paddle limbs, moist copper-green skin, sensory crown, walking through tidal flats under muted red sunlight, natural history museum illustration.

Requirements:
- Body plan reflects TOI-700 d's slightly-above-Earth gravity: compact, sturdy, low center of mass, strong paddle limbs, no tall spindly anatomy.
- Sensory organs reflect its red-dwarf lighting: large dark red-light-sensitive eyes and a sensory crown adapted to muted red sunlight.
- Skin and metabolism fit a temperate possible shoreline or marsh world: moist copper-green amphibious skin, protective slick texture, subtle thermal patterning.
- Depict the planet as well as the creature: show rocky tidal flats, shallow water channels, damp mineral sand, low marsh-like alien growths, muted red sunlight, red-dwarf sky, atmospheric haze, distant shoreline, and a broad horizon.
- The environment should communicate a rocky habitable-zone exoplanet with possible ocean-bearing tidal flats even without captions.
- Make creature and environment feel physically connected: wet footprints, water displacement around paddle limbs, reflections in shallow pools, posture shaped by slightly higher gravity, and gentle shore wind.
- Use a surface-level shoreline habitat view. Do not show the planet itself as a separate sphere in the sky; do not add unexplained moons or extra planets.
- Avoid humanoid anatomy unless scientifically justified.
- Show the creature in its natural habitat with enough space in the frame to read the world around it.
- Style: natural-history field-guide illustration, realistic scientific/anatomical detail, documentary lighting, one unified scene.
- Composition: 3:2 wide landscape; balance a clear creature portrait with a readable planetary landscape/seascape. Do not crop so tightly that the world is reduced to a blurred background.
- No text or labels baked into the image. No official logos, no photorealistic real people.
