The goal of the study was to learn more about the Geonemertes pelaensis. A generalized search will be done in there known habitat in tropical island area, Seychilles, where observations will be kept on locations found. Scientists will then try provide a sustainable habitat, and observe unknown features of there behaviour and diet.

Until this study no Geonemertes pelaensis samples where successfully preserved alive for any period of time. They require a moist humid environment, and won’t survive otherwise. It is extremely hard to view activity (behaviour) since they are nocturnal creatures and will hide at the presence of the slightest light.

Samples of Geonemertes were collected, and the percentage of different areas where a sample was observed was also kept (banana leaves, rotten logs). The samples were then put in a box with an abundance of prey. Four types of prey were tested, small gastropods, collembolan, mites, and isopods. G. pelaensis was found in 100% of the banana leaf sites, 33% of the palm leaf sites, and 50% of the dead tree sites. They consumed prey on an average of 0.6 a night, with 2 per night as a maximum.

  • The species G. pelaensis was most commonly found 60 cm above ground, perhaps due to predation from the terrestrial crab. It was most commonly found in dead trees, banana leafs and palm leafs, and not near dry or coastal areas. They prey on small gastropods, specifically liordetiasculpta, Allopeasgracile, and subulinaoctona
