Sekots

Sekots are a fictional species from the science fiction novel "A Door into Ocean" by Joan Slonczewski. They are an amphibious, bioluminescent race native to the ocean planet of Valedon. Sekots possess a unique physiology, with smooth, dark skin that allows them to absorb atmospheric moisture and filter oxygen directly from the water. They communicate through a complex system of bioluminescent displays and subtle infrasonic vibrations, which can travel great distances through the ocean.

The Sekots are a deeply communal and peaceful society. They have no concept of individual ownership or personal property, sharing resources and living in harmony with their environment. Their culture is based on mutual respect, understanding, and a profound connection to the ocean and its lifeforms. They are also highly intelligent and possess advanced knowledge of biology and ecology, which they use to maintain the delicate balance of Valedon's ecosystem.

In the novel, the Sekots are encountered by a human expedition. Their unique way of life and their pacifist nature present a significant contrast to the more hierarchical and militaristic human society, leading to cultural clashes and profound philosophical questions about the nature of civilization and coexistence. The Sekots' reliance on their watery environment makes them vulnerable to changes in the ocean's chemistry, a concern that becomes central to the narrative.
