Squamosa Clam – Aquacultured
The Squamosa Clam, also known as the Scaled Clam, gets its name from the Latin word ‘squamosa,’ meaning scale. Its shell features numerous rows of large scales that cover the entire surface, often serving as shelter for small crabs, bivalves, and other sessile invertebrates.
The shell is symmetrical, and its matching growth pattern allows it to close tightly, providing strong protection against predation. It has a wide byssal opening and long tentacles surrounding its incurrent siphon. The clam attaches weakly to solid substrates using byssal filaments.

FAQ
What makes the Squamosa Clam unique compared to other clam species?
The Squamosa Clam is distinguished by its large, scale-like patterns across the shell, which provide shelter for small invertebrates. Its symmetrical structure and tight closure ability offer strong protection from predators.
How does the Squamosa Clam attach to its substrate?
It attaches weakly to solid surfaces using byssal filaments, which extend from the byssal opening and anchor it to the substrate.
Is the Squamosa Clam suitable for reef aquariums?
Yes, due to its ability to provide shelter for small invertebrates and its compatibility with reef environments, it is well-suited for reef aquariums.

The Squamosa Clam arrived healthy and showed active movement in the tank. The scale patterns on its shell are very striking and it has become a natural shelter for a small crab I keep. It’s easy to place and stays attached well.

I added this clam to my reef tank and it has been thriving. The scales look beautiful and it’s become a focal point. It doesn’t seem to interfere with other inhabitants and provides a nice hiding spot.

The clam is very active and has adapted quickly to the tank conditions. I appreciate the natural look it adds. The byssal attachment is stable and it doesn’t drift around.
