The unusually monstrous eel took two grown men to hold it up.

According to reports, the moray eel - a common fishermen’s catch in Hong Kong - weighed around 15kg and is about six times longer than the typical moray eel people see in the wet markets.

The stallkeeper said what makes the catch even more special is that the eel is caught by a fisherman using a small bait instead of using any fishing traps.

At the stall, the eel was divvied up into small pieces and sold at around HK$100 for a catty, the equivalent of around 600 grams.

By mid-afternoon, most of the eel had been snapped up, with just a third of it remaining.

According to the Centre for Food Safety, moray ell is one of the fish that may cause Ciguatera Fish Poisoning and Ciguatoxins.

Around 24 to 48 hours after consumption of ciguatera fish poisoning fish, initial symptoms - both gastrointestinal or neurological - will start to develop, including vomiting, diarrhea, nausea and abdominal pain, lasting only for a few days.

But neurological symptoms like tingling of lips, hands and feet, skin itching, change in temperature perception, fatigue, muscle and joint pain appear later and last longer, sometimes up to a few years.

In severe cases, low blood pressure, slow heart rate, respiratory difficulties and paralysis are possible, but death is uncommon.
