Crystal Jellyfish
Aequorea victoria · also called crystal jelly
Nearly invisible in its own coastal waters, a crystal jellyfish has had an outsized impact far beyond the ocean, its glowing protein now lighting up laboratories worldwide as one of modern biology’s most valuable research tools.
Overview
The crystal jellyfish, Aequorea victoria, is a small, transparent jellyfish native to coastal ocean habitat along the west coast of North America in the North Pacific. Its production of green fluorescent protein, transformative impact on modern scientific research, and status as a Nobel Prize-linked discovery make it one of the most scientifically significant animals found anywhere in the ocean.
An animal that changed how science sees cells
Few animals have shaped modern biology as profoundly as the crystal jellyfish, whose naturally occurring glowing protein gave researchers an entirely new way to watch living cells and proteins in action, a tool now used in laboratories across the world.
Status
Least Concern, remaining widespread across suitable coastal ocean habitat in the North Pacific.
Crystal Jellyfish: common questions
Why is the crystal jellyfish so scientifically important?
This species produces green fluorescent protein, a molecule that has become one of the most widely used tools in modern biology and medicine, allowing researchers to make specific proteins and cells glow visibly under a microscope to study how they behave.
Did the crystal jellyfish's discovery really lead to a Nobel Prize?
Yes, the discovery and development of green fluorescent protein as a research tool led to a Nobel Prize in Chemistry, recognising just how transformative this molecule became across many fields of biological and medical research.
Why is it called the crystal jellyfish?
This species has a nearly transparent, glass-like body, a feature clear enough to give the species its common name.
Does the crystal jellyfish glow on its own in the wild?
Yes, this species produces a light-emitting protein called aequorin alongside its green fluorescent protein, together producing the characteristic green glow the species is known for in its natural habitat.
