Moon jelly can be identified by which feature?

• A. 500-yard approach limit by law
• B. Protected, avoid disturbing nests
• C. Translucent bell with horseshoe gonads
• D. Rock crab, green crab, Jonah crab

Answer: (C)

Moon jellies are most easily identified by a bell that is almost completely translucent, with four horseshoe-shaped gonads visible in the center. The gonads appear as a distinct, curved pattern in orange or brown that stands out against the pale bell. This combination—the see-through bell plus the recognizable horseshoe gonads—is the reliable visual cue that distinguishes Moon jelly from other jellyfish and from non-jelly species.

Other choices describe legal limits, nesting protections, or different animals (crabs) and don’t reflect jellyfish appearance, so they don’t fit the identification feature.
