プロジェクトデータ
Otoplanid flatworms live in the surf zone of sandy beaches. In spite of their presumed poor dispersal capabilities, several taxa have been recorded across the Arctic. This project was designed to investigate explanatory factors for their wide distribution such as cryptic speciation and continuous, cross-oceanic dispersal.

| ファンデイング | Funding for this study was provided by the University of the Arctic’s North2North travel grant and by the Norwegian Biodiversity Information Centre. |
| Study Area Description | The project investigated flatworms in areas of northern Norway, Greenland and Svalbard. |
| 研究の意図、目的、背景など（デザイン） | Flatworms were collected, studied morphologically, and subjected to DNA extraction and amplification to investigate their phylogeography and the presence of cryptic species. |

収集方法
Flatworm specimens were retrieved from marine beaches in Greenland (Nuuk), Svalbard (Longyearbyen), and Norway by collecting surf-zone sand and seawater in a bucket. In northern Norway, two locations were sampled – the in-fjord Telegrafbukta beach in Tromsø city, and the island of Sommarøy in the outermost archipelago. In Nuuk and Sommarøy, a sea water salinity measurement was taken using a Kern Optics analog refractometer. Flatworms were extracted from recovered sand by mixing it with a solution of 7% MgCl2 in sea water in an Erlenmeyer flask. The flask was turned upside down a couple of times before decanting the aqueous solution with suspended flatworms into a 63 µm sieve. The sieve was placed in a petri dish containing sea water before flatworms were manually picked out, and specimens of each species placed into separate embryo dishes using a glass Pasteur pipette. When practically possible, specimens were starved in clean seawater in a refrigerator for a few days before they were photographed under microscopes or stereo microscopes, depending on what was available at the sampling location.
