Boltenia ovifera explained

Boltenia ovifera is a species of ascidian tunicate in the family Pyuridae. It is found in the Arctic to the South of Cape Fish. Boltenia ovifera has an average lifespan of 6 years and it can house small invertebrate creatures like the tuna. Under a microscope it was observed that they have spines. 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.
