Ptilosarcus gurneyi (orange sea pen, sea feather) is a species of soft coral that emits a strong green fluorescence when disturbed. The green fluorescent protein obtained from this organism exhibits nearly symmetrical excitation and emission peaks. This is in contrast to the more commonly employed GFP from Aequorea victoria which has two wavelengths at which excitation occurs, and a broader emmision spectra.
