Pyrosome

Part of speech: noun

Definitions

1. A colonial marine organism characterized by its elongated, tube-like gelatinous body which houses multiple connected zooids in a communal structure that floats in warm oceanic waters
2. This aquatic creature is made up of numerous individual zooids that collectively form a hollow, tubular shape, typically found drifting in warmer seas
3. A gelatinous marine colonial organism consists of many individual zooids that together create a long, tubular formation, commonly residing in warm oceanic environments

Etymology: Pyrosomes are drifting sea animals made of many tiny linked individuals, and the name describes their most striking feature. It combines Greek "pyr", meaning fire, with "soma", meaning body, so the animal is a fire-body. The colonies produce their own light, and they can flash brightly when disturbed. Each colony is built from individual zooids that share a common tube, so the name refers to the whole organism rather than any single member. The word is a technical coinage made from two ordinary Greek words, not an old term that developed through speech.
