Captures the features of the Triassic marine reptile—long, flexible neck, streamlined, muscular torso covered in textured, scaly skin (warm brown base with subtle darker brown striping, as seen in the image), paddle-like forelimbs and hindlimbs adapted for both swimming in shallow seas and crawling on shorelines, and a long, muscular tail for powerful propulsion. Its iconic elongated, pointed skull is meticulously replicated, with a slightly open mouth revealing sharp, conical teeth adapted for seizing fish and small marine prey, exuding a sleek "Triassic marine predator" vibe that reflects its carnivorous nature in the warm, shallow coastal waters of the ancient Tethys Ocean.

Equipped with a drive system for natural head swings (left and right, up and down), jaw opening/closing synchronized with sharp, predatory snaps and low, guttural calls, and dynamic tail sways (side to side). Paddle-like forelimbs can make gentle, paddling motions (simulating swimming strokes), while the torso shifts subtly to suggest slow, deliberate crawling along a prehistoric shoreline or gliding through shallow water. Movements are smooth and fluid, no abrupt transitions. Can be fixed on a simulated Triassic rocky shoreline or shallow sea base or ground bracket to enhance the "ancient Tethys coastal waters" scene.

Adjustable size (fitting park/museum spaces), skin texture (smooth or with fine scales), color (matching theme areas—e.g., warm brown tones for coastal settings, gray hues for deeper marine environments), and movement modes ("static display with predatory alert posture" or "low-frequency dynamic motions like head bobbing and tail flicks"). Supports adding interactive sensors (head turning and low growls when visitors approach) or installing a safe photo platform nearby (for children to "interact with the Triassic marine hunter" through snapshots).

Frame made of lightweight alloy (easy to install and stable), body skin of weather-resistant silicone (scratch-proof, UV-resistant). All moving joints are buffered with no sharp edges. Electronic components are waterproof and dustproof, adapting to outdoor or indoor aquatic-themed environments. Daily maintenance involves surface cleaning and line checks, suitable for high-traffic parks, museums, and theme parks.
