Species overview
About the Eastern Pacific Giant Conch
This conch is known as cambute in Costa Rica. Older sources use Strombus galeatus or Lobatus galeatus. Costa Rica’s National Museum describes archaeological shell instruments made from this species.
Explorer activity: Compare a natural shell with the museum’s photograph of a shell instrument. Describe the difference in your notebook without modifying a shell yourself.
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.
Identification
Key Features of the Eastern Pacific Giant Conch
Large, thick shell.
Adult shells have an expanded outer lip and a short spire.
Look for older scientific names when comparing historical references.
Habitat & range
Pacific coastal marine habitat; local encounters require confirmation.
Local observations
Pacific Costa Rica records and Bahía Culebra archaeological material. 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.
