Protanguilla palau, the Palauan primitive cave eel, is a slender, eel‑like fish that inhabits marine caves and crevices around Palau. At a maximum length of just 17.6 cm it is rarely targeted by anglers, but its elusive nature makes it a novelty for light‑tackle specialists seeking unique reef species.

Fishing Tips for Palauan primitive cave eel

  • Approach cave entrances quietly and cast a light jig or soft plastic near the opening to tempt the eel out
  • Use a very light line (2‑4 lb test) and a small hook to prevent snagging on rocks
  • Target during low light periods—early morning, late evening, or night—when the eel is most active
  • Keep the retrieve slow and gentle; a subtle twitch can mimic natural prey and trigger a bite
