Mires, bogs & fens Grasslands and landscapes dominated by forbs, mosses or lichens Regularly or recently cultivated agricultural, horticultural or domestic habitat Constructed, industrial or other artificial habitats Reproduction terrestris but not on epigecic species (worms that live on the surface or in leaf litter), (Murchie & Gordon, 2013). The impact on earthworm biomass was particularly acute in the case of anecic species (worms that make permanent burrows in the soil) such as L. New Zealand flatworms have been shown to significantly reduce the biomass of earthworms ( Lumbricus terrestris and, to a lesser extent, Aporrectodea longa) in field plot experiments (Murchie & Gordon, 2013). Produces shiny, black oval eggs (capsules), 1-2mm in width (Booy et al., 2015). Up to 15cm in length and can weigh more than 2g (Blackshaw, 1990). Entire body covered in a fouling smelling sticky mucus. Thus, they are highly invasive and frequently show up in new regions.Flatworm with a very flat body, non-segmented and pointed at both ends brown upper body (often dark brown to purplish) with pale speckled edges and with a pale buff coloured underside with grey-brown specks (Booy et al., 2015). They easily hide among objects and in soil where there's moisture, so moving any type of container or plants around the world has allowed them to colonize new areas. "However, some have been here for over 100 years, so they are well established. are not native," says Matt Bertone, an entomologist at NC State University. "The majority of land flatworms in the U.S. Over the course of the past couple of hundred years, global commerce has helped the hammerhead worm wriggle its way into most suitable habitats in the world - and there are a lot of suitable habitats out there, although you're unlikely to find them in a desert or at the top of a mountain. These predatory planarians are native to tropical and subtropical regions of the globe, so they love wet, warm spots. But hammerhead worms, all members of the genus Bipalium, aren't something to get too fussed about as they're not a new thing in the U.S., or in most places in the world - they've been common residents of American gardens since the early 1900s.
