A recently discovered invasive worm species from Asia has been found in the Montreal area, causing concern among experts and residents. The hammerhead flatworm, known for secreting a dangerous and paralyzing toxin, has been sighted in significant numbers, prompting worries about its potential impact on the local ecosystem and public health.
Lisa Osterland, a retiree from Westmount, Que., stumbled upon around twenty hammerhead flatworms while removing slugs in her garden. Unaware of the species at first, she later recognized them in a CNN report about their spread in New York. Osterland promptly handed the worms over to a team of entomologists at the Universite de Montreal, including Etienne Normandin.
Normandin, a member of the entomology team, revealed that the hammerhead flatworm population is estimated to be in good health based on their observations. He explained that the worms secrete tetrodotoxin, a potent toxin similar to the one produced by pufferfish. The toxin can cause paralysis and is particularly harmful if ingested, posing a risk to children and animals.
Aside from the threat to human health, the hammerhead flatworms also pose dangers to birds, dogs, and other animals that frequent gardens. Their predation on slugs, snails, and millipedes disrupts the natural balance and negatively impacts soil biodiversity. Normandin emphasized the importance of these species in recycling organic matter and warned about the potential long-term effects on soil fauna.
The invasive species is believed to have arrived in North America through cargo ships carrying plants from Asia. Normandin pointed out that affluent neighborhoods, such as Westmount, often have exotic plant species that are imported from other countries, providing a suitable environment for the hammerhead flatworm to thrive.
Awareness about the invasive worm’s presence in Quebec is crucial, as it can contribute to the global economic cost caused by invasive species. Additionally, with the influence of climate change and warmer winters, the hammerhead flatworm is given a greater opportunity to establish itself and expand its range in Montreal.
