Unearthly, transparent and beautiful—and also exceedingly delicate. The spotted comb jelly is so fragile a creature, just waving your hand through the water could destroy it. Now, for the first time anywhere, animal care staff at the Monterey Bay Aquarium have managed to culture these fragile, scintillating creatures.
Several of the newly hatched jellies are now on public display. It’s the latest advance in comb jelly science from the Aquarium team.
The species, known scientifically as Leucothea pulchra—Latin for “beautiful sea goddess”—is “a clear football-shaped gelatinous animal” says Wyatt Patry, a senior aquarist who’s worked at the Aquarium for 11 years, and who led the culturing effort this winter.
“They’re ctenophores, not true jellyfish,” Wyatt notes. “Instead of stinging cells they have sticky cells called colloblasts.”
The spotted comb jelly’s common name refers to orange “knobs” or spots along its body.
“We don’t know what those do but we suspect they aid in prey capture,” Wyatt says. Two sticky tentacles trail behind it, acting like fishing lines.
“They also have cool whips called ‘auricles’ that they wave around—undulate—in this really cool slow wave motion, probably driving food into their mouths,” he says.
