About Petrochirus diogenes (Linnaeus, 1758)
The giant hermit crab, known scientifically as Petrochirus diogenes, is a species of marine hermit crab. This species lives in the Caribbean Sea, and it often inhabits conch shells. It is large enough to occupy the fully grown shell of the queen conch. This hermit crab will attack and eat a conch, gaining both food and a shell in the process. It was originally described by Carl Linnaeus under the name Cancer diogenes; its specific epithet honors Diogenes of Sinope.
