Dangerous Lion’s Mane jellyfish have been swarming the capital’s coastal hotspots with hundreds of beachgoers and their dogs getting stung in recent weeks - but now there’s another nasty critter doling out pain on the sand along Dublin's strands.
Weeverfish - almost invisible little creatures that bury themselves in the shallows along the shoreline - with just their eyes and dorsal fin exposed - have begun popping up along the city’s coasts at low tide.
The fish - which are around 15cm long and are very hard to see because they camouflage themselves in the sand - have a black dorsal fin from which very sharp poisonous spines protrude that unsuspecting beachgoers have no way of seeing until they stand on one.
Weeverfish stings have been known to trigger heart attacks or cause a severe allergic reaction including anaphylactic shock - with deaths being attributed to the fish both in Britain and in Spain.
Dublin Live reader Gerry Murphy got in touch to say he’d seen weeverfish at Donabate, while Portmarnock Drainage Awareness, which is run by keen fisherman and naturist Philip Swan, also warned of sightings of the venomous fish along its Velvet Strand.
Philip posted a useful piece of information relating to the dangerous sea creatures on the PDA Facebook page.
The advice, which Portmarnock Drainage Awareness sourced from the National Poisons Information Centre, says: "The Weeverfish is found in all parts of the Irish coast but only in sandy areas, usually in warm shallow waters in the hour before and after low tide.
"They are difficult to see because they spend most of their time buried under the sand. The have sharp spines containing venom on their dorsal fin."
The memo also includes some advice on what to do if you get stung.
WHAT TO EXPECTStanding on a Weeverfish results in immediate intense, burning pain.
The pain is most intense in the first 2 hours and can result in swelling, numbness and warmth.
WHAT TO DOSeek assistance from a lifeguard, if available.
Submerge the affected limb or wound in hot water, as hot as can be tolerated for up to 90 minutes or until pain is easing.
As the sting can result in numbness, immerse the unaffected limb too, as this may prevent inadvertent scalding.
Cold applications may worsen the discomfort.
Paracetamol can be considered to relieve pain.
The puncture site should be examined and embedded spines removed.
Tetanus and/or antibiotics may be required.
Seek medical attention from a doctor, if necessary.
