Poolien

Poolien is a fictional semi-aquatic mammal species created for the fantasy setting known as the Poolien Chronicles. It inhabits freshwater pools and wetlands and is noted for its adaptability, gentle demeanor, and distinctive bioluminescent markings.

Etymology and taxonomy: The name Poolien is a compound of pool and -ien, common in the setting for aquatic mammals. In-universe classification places Poolien in the fictional family Poolidae, with the species Poolien poolien.

Physical characteristics: Adults reach 60–90 cm in body length, with a broad, rounded muzzle, webbed hind feet, and a short, muscular tail. The fur is dense and water-repellent, colored from slate blue to olive. Bioluminescent spots along the sides glow faintly under low light.

Habitat and behavior: Poolien dwell in freshwater pools, wetlands, and slow-moving streams across the Verdant Basin. They live in small social units of 3–8 individuals, are omnivorous, and feed on aquatic plants, insects, and small fish. They are adept swimmers and use vocalizations and scent marking to communicate.

Reproduction and life cycle: Breeding occurs in spring; gestation lasts about 60–65 days with litters of 2–3 offspring. Young remain with the group for several months, learning foraging and swimming skills before dispersing.

In culture and conservation: Within the Poolien Chronicles, the poolien is a symbol of cooperation and water stewardship. They are commonly depicted in murals and festivals celebrating freshwater ecosystems. In real-world fan content, conservation-themed stories emphasize habitat protection for aquatic species.
