Regional Impacts

Ecological ImpactHabitat Change
Mucus from the tubes of Laonome sp. as well as the mucus produced by other native and introduced deposit feeding and tube-building benthos, contributes to a surface layer of flocculent fluff, which may trap much more phtyoplankton than that actually consumed by the animals (Jones et al. 2009).
