A family of red algae with hair-like filaments, found in marine and freshwater environments.
From Greek χαίτη (chaitē) meaning hair, and ἄγγος (angos) meaning vessel or container, plus the taxonomic suffix -aceae for plant families.
These delicate red algae look like tiny underwater hair sculptures, and some species can actually glow faintly—they're using bioluminescence to attract particles in the dark ocean depths.
