Common Mola
Mola mola
The common mola, or ocean sunfish, is a huge, laterally flattened pelagic fish best known for its truncated body and drifting near the surface. It feeds mainly on jellyfish and other gelatinous zooplankton, and is rarely targeted by anglers.
Identification points
- Very tall, rounded dorsal and anal fins set far back on a truncated, disk-like body
- No obvious tail fin; the rear ends in a rudder-like clavus instead of a normal caudal fin
- Small mouth and eye compared with the body, with rough, leathery skin and no visible pelvic fin
Habitat
Open-ocean temperate to tropical waters worldwide; often seen near the surface, around fronts, drifting with currents, and occasionally near jetties or offshore structures where jellyfish aggregate.
Bait notes
Not a standard game fish. It is not intentionally baited for in most fisheries; incidental captures can occur on large pelagic hooks or drift gear used for tuna, swordfish, or shark. Avoid targeting it.
Behavior
Slow-moving and largely solitary; spends much of its time basking near the surface or cruising in open water, then makes short dives. Feeds on jellyfish, salps, ctenophores, squid, and small fish.
Caution
Use caution when handling: the skin is thick but the fish is extremely heavy and can be injured by lifting. Observe local protected-species rules and release requirements; consumption is generally not recommended because regulation and food-safety rules vary by region.
Fishing notes
Encounters are usually accidental in offshore trolling, longlining, or drift operations. If hooked, reduce fight time and handle minimally; their body shape and skin make them vulnerable to injury. Check local regulations, as many areas protect sunfish or require release of bycatch.
