Annelids, particularly certain species of earthworms and leeches, can have harmful effects in specific contexts. For instance, invasive earthworm species can disrupt local ecosystems by altering soil composition and nutrient cycling, negatively impacting native plant species and soil-dwelling organisms. Additionally, some leeches can pose health risks to humans and animals by transmitting diseases or causing infections through their bites.
