Species overview
About the Rough-ribbed Nerite
This nerite grazes films of tiny organisms on coastal rocks. Its rough spiral ribs are a useful starting clue, but a worn shell may look different from a fresh one.
Explorer activity: Sketch the direction of the ridges. Compare the drawing with the funiculate nerite card. Which details would you photograph to tell them apart?
Your discovery notes: Record the date, place and habitat, then add a sketch or photograph. If you cannot confirm the species, label it “unidentified shell” and keep your observations.

Local observations
Pacific Costa Rica: Punta Mala and Bahía Panamá records. This supports regional inclusion, not a confirmed Tamarindo Beach sighting.
When to observe
Tides and conditions affect visibility. Let an adult or local guide choose a safe observation time; this card does not promise a seasonal sighting.
Conservation & care
Observe and photograph shells where they are. Leave living animals, occupied shells and empty shells in place. Do not pry animals from rocks, dig in mangroves or put fingers into shell openings. Explore with an adult or guide, follow site rules and stay clear of surf and slippery rocks.
