the closest thing to immortality, drifting brainless and 95% water through every ocean since before dinosaurs
means A soft-bodied, gelatinous marine animal with trailing stinging tentacles and no brain, bones, or heart, drifting through the world's oceans.
from A transparent compound of English's own making: "jelly" (from Old French gelee, "a frost" or congealed thing, ultimately from Latin gelare, "to freeze") plus "fish" — though the creature is no fish at all. The name simply describes what people saw: a wobbling lump of cold jelly afloat in the sea. It surfaces in English around the early 18th century, joining the long, slightly inaccurate tradition of calling anything ocean-dwelling a "fish" (see also starfish, cuttlefish, shellfish).
