Panopeidae
Panopeidae is a family of large, burrowing, saltwater clams, commonly known as geoducks, in the order Veneroida. These clams are found in the northeastern Pacific Ocean from Alaska to Mexico, as well as in the northwestern Pacific Ocean. Geoducks are notable for their exceptionally long siphons, which can extend several feet from their burrows. They are an important food source for humans and marine predators alike, and their unique features make them a fascinating subject of scientific study.
Common Names
Panopeidae are commonly referred to as "geoducks", pronounced "gooey-ducks". This name is derived from the Salish word "gʷídəq", which translates to "dig deep".
Characteristics
Members of the Panopeidae family share several distinguishing characteristics:
- Large Size: Geoducks are among the largest edible clams in the world, with some individuals reaching lengths of over a foot and weights exceeding 10 pounds.
- Long Siphons: Geoducks possess extremely long siphons, which they use to filter food particles from the surrounding water. These siphons can extend several feet from their burrows, making them vulnerable to predation.
- Burrowing Behavior: Geoducks are burrowing clams, digging deep into the sediment to create their homes. Their burrows can be several feet deep, providing them with protection from predators and the elements.
- Long Lifespan: Geoducks are known for their exceptionally long lifespans, with some individuals living for over 100 years.
Environments
Panopeidae are found in marine environments with soft sediment bottoms, such as sand, mud, and gravel. They prefer areas with moderate wave action and a good supply of food. Geoducks typically inhabit intertidal and subtidal zones, often at depths of up to 100 meters.
