In their natural habitat, the ocean floor, clams usually open their mouths when they think there's food nearby. To open clams in the kitchen, soak the clams in warm, salty water for 15-20 minutes. A small gap should appear, and then you can wrench them open with your fingers or 2 butter knives.
Yes. I had a small one that never opened and then one day it was dead and opened all the way. I believe their "bodies" kinda discinergrate because there was nothing inside of it then.
By using their "stomache foot."
Yes or no
yes, sea stars can eat clams. They use their tube feet to open the shells and then eat the clams tissue.
Until the shells open.
Clams open when cooked because of the pressure that builds inside of them. When temperatures increase the molecules and atoms inside of the shell move fast enough to pop the shell open.
Little particles
If a clam does not open when cooked, that usually means the clam was dead before cooking. Do not eat clams that won't open when cooked. Make sure that the clams have plenty of space to open during the cook. Sometimes the weight on top will prevent opening.
I am not sure how to get a clam to open naturally. The way I have known to open a clam is by hand.
Starfish pry clams open in a very unusual way. They use their legs and suction cups to position and open, then push their stomach out of their body and grab the clam. Once the starfish has the clam, it withdraws the stomach back into the body.
Clams are generally covered by a shell. It is a part of the clam's body, and it can open or close; when closed, it serves the purpose of protecting the clam from predators.
Starfish eat clams by grasping and pulling on the clams shell until the clam can't hold it close any longer. Once the shell is opened far enough, the starfish begins to feed on the clam.
Starfish have suction-like cups helps to open clams
The suckers
No. Clams that are dead will open up. Live ones use their muscles to stay shut. This rule works with mussles and oysters too. Hooweestik.
