A tragic death in Puerto Princesa City has prompted renewed warnings from the Bureau of Fisheries and Aquatic Resources (BFAR) after a local content creator unknowingly consumed a highly toxic marine species known as the devil crab.
Emma Amit died on February 6 after eating a devil crab she had found in Barangay Luzviminda. Authorities later confirmed that the crab, scientifically identified as Zosimus aeneus, contains potent toxins comparable to those found in pufferfish.
According to BFAR Palawan, the devil crab is commonly seen in rocky coastal areas across the province. While it resembles ordinary crabs or swimming crabs, it is strictly prohibited from being harvested or eaten due to its toxicity.
Aquaculturist Argie Wong of BFAR Palawan explained that the devil crab is relatively small, with a carapace measuring up to six centimeters and weighing less than 10 grams. Unlike the more familiar alimasag, which has pointed edges on its shell, the devil crab has a rounded body and remains small throughout its life.
Its vibrant coloration, often eye-catching and attractive, is a warning sign rather than a harmless feature.
“Most brightly colored marine species — not all, but many — are toxic,” Wong said. “If you are not absolutely sure what it is, do not attempt to eat it.”
The danger lies in the crab’s chemical composition. The devil crab contains tetrodotoxin (TTX) and saxitoxin (STX) — the same neurotoxins found in pufferfish and shellfish contaminated by red tide.
These toxins are heat-stable, meaning they cannot be destroyed by boiling, frying, or any other cooking method. Once ingested, symptoms can develop rapidly — typically within 10 to 45 minutes.
Initial signs of poisoning include numbness of the lips, dizziness, and weakness. In severe cases, paralysis can occur, leading to respiratory failure and death.
“In some instances, symptoms can appear in less than 10 minutes,” Wong noted, referring to the recent incident. “It varies per individual, but the progression can be very fast.”
BFAR confirmed that at least three deaths in Barangay Luzviminda have now been linked to the consumption of devil crab. In response, the agency has intensified its information and education campaign in the community, distributing materials to warn residents about the risks.
The incident underscores a broader public safety issue in coastal communities, where foraging for seafood remains common practice. Officials stress that unfamiliar marine species — particularly those with striking colors — should never be consumed without proper identification.
The warning is clear: when it comes to the devil crab, one bite can be fatal.
