Boltenia ovifera is a species of ascidian tunicate in the family Pyuridae. It is found in the Arctic to the South of Cape Cod. Boltenia ovifera has an average lifespan of 3 years and it can house small invertebrate creatures like the red king crab. They group in long stalks around 20-30 cm, they are found in the ocean on a substrata around 10-300m. Under a microscope it was observed that they have spines on their external surface. Inside the tunic, no real organized cellular system was observed. It was also noted that they have a single layer heart, where each cell had a single microfibril.

Scientists observed in the areas of sea potatoes, there were anemones and soft corals, which are both “Filter-feeding macroinvertebrates”. More profuse people are around the areas of the sea potatoes. The scientist concluded that the sea potatoes were acting as a “biogenic habitat to enhance local species richness in the rocky subtidal zone” (Francis et al. 1375).

A recent study by Nova Scotia found that 22 species grow on these sea potatoes . The most common animal we find on these potatoes are young cods hiding from their predators. This reaerch could help because this could help scientists discover new animals or even new areas that some creatures can live/hide. With this, we can research potential habitats for new animals that are in danger of losing their homes and can see if these sea potatoes have any habitat or food chain to provide for sea creatures to surve of.
