How to spot the Flagpole Frogfish when scuba diving

Antennarius multiocellatus

Found in tropical and subtropical oceans worldwide, except the Mediterranean Sea. Highest diversity is in the Indo-Pacific, particularly around Indonesia (e.g., Lembeh Strait).

When to spot

Can be found year-round. Time of day is less critical than knowing where and how to look. Patience is key.

Water

Tropical and subtropical ranges.

How to spot

Masters of camouflage, often found sitting perfectly still on or near sponges, corals, or rocks that match their color/texture. Check muck diving sites (rubble, sand, discarded debris), reef structures, pier pilings, and even floating Sargassum weed (Sargassumfish). Look for the lure (esca) twitching or unusual shapes. Requires a keen eye and slow searching.
