TL;DR

To find soft shell clams, look for 'clam shows' — small holes in the sand indicating clams below. Dig carefully, as these clams have brittle shells. They can filter up to 50 liters of water daily and have interesting life cycles: starting as planktonic larvae before settling in estuaries for up to 12 years.

Questions & Answers

Q: What is the significance of the clam shows in the sand?

The clam shows, or holes in the sand, indicate the presence of clams just below the surface. They are a telltale sign for clamming enthusiasts.

Q: Why are soft shell clams called squirting or spraying clams?

Soft shell clams are called squirting or spraying clams because they can expel water through their siphons. This behavior helps them filter water and obtain oxygen.

Q: How much water can soft shell clams filter in a day?

Soft shell clams can filter up to 50 liters of water a day. This impressive filtering ability allows them to consume microscopic algae and other food sources.

Q: How do soft shell clams know where to settle and spend the rest of their lives?

Soft shell clams release a sticky substance called byssal to attach themselves to the seabed. They then ride the tide back to estuaries and use their foot to dig down and find the perfect spot to live.
