Sand gaper

Deep digger

Sand gaper dug down into the sediment
The Sand gaper starts its life as a larva, hovering rather than swimming in the water. After a few weeks it falls to the bottom and starts a bottom living existence. There, the gaper digs down into the bottom sediment and is more or less stationary the rest of its life. The larger and older the gaper is, the deeper it lives in the sediment. At one year it is found at between 5-10 cm down, and at ten years it can as far down as about 40 cm. The young mussels run the risk of being fish food, while the larger and deeper living mussels are almost inaccessible to predators and do not freeze to death, even during harsh winters. They can be as old as 10-12 years.
