Casparyns

Casparyns is a fictional genus of bioluminescent plankton described in the science-fiction setting known as the Casparyn Sequence. In that universe, Casparyns are an essential component of coastal and shelf ecosystems and are frequently referenced in discussions of marine energy cycles and planetary biology.

Casparyns are colonial organisms formed from a network of cell-like units called casporoids. Individual casporoids measure about 0.5 to 2 millimeters in diameter and display synchronized bioluminescence that can form shifting patterns along the colony's edge. The colonies reproduce by budding from specialized units.

Habitat and ecology: Casparyns inhabit tropical to temperate coastal waters, often aggregating on reef margins and in seabed mats. They are filter feeders, contributing to nutrient cycling, and form symbiotic relationships with certain algae that enhance light production.

Discovery and taxonomy: The Casparyns were first described by researchers within the Casparyn Sequence as part of a paleoceanographic model; their classification varies by source within the universe, with some taxonomies placing them in a provisional family Casparyniaceae. Reproduction and life cycles are topics of ongoing in-universe study.

Significance: In-world scientists study Casparyns for insights into bioluminescence, photonic networks, and potential bio-inspired materials. They appear in ecological simulations and are used as a narrative device to explore climate change and ocean health.
