What has the author Joy Sikorski written?
Joy Sikorski has written: 'How to Draw a Clam'
What is the movement of food through the clam's digestive system?
Water and food particles are drawn in through one siphon to the gills where tiny, hair-like cilia move the water, and the food is caught in mucus on the gills. From there, the food-mucus mixture is transported along a groove to the palps which push it into the clam's mouth. The second siphon carries away the water. The gills also draw oxygen from the water flow.
What features of a clam anatomy enable it to survive in a marine environment?
They have a hatchet-shaped foot that allow them to move, incurrent and excurrent siphons through which water passes and then they filter feed in that way, and powerful abductor muscles that draw the shell together to protect the clam's soft body.
How can scientists lean about the mantle if they cannot study it directly?

HOw can you tell a clam is dead?
The tissue around the edges of the shell will draw back and the meaty substance of the animal will deteriorate. You can also do the smell test, though be prepared. Same works with snails. Remove from water and sniff. If you nearly regurgitate then it is deceased.
