Penguins are birds that survive in extremely cold conditions.
They spend most of her life in water, feed on fish, krill and squid.

Geoducks, pronounced “gooey-ducks,” are one of the largest burrowing clams known. The two halves of the bivalve shell cannot contain the large fleshy animal. Geoducks live buried deep in the gooey mud of large bays, relying on this burrow for protection. The only way to see them is to dig deeply into the mud when the tide is out.
While walking across a mud flat, you may see a startled geoduck send a tall spout of sea water squirting from its siphon as it retracts its neck and siphon into the mud.
When the tide is in and water covers the burrow, the geoduck clam draws water into one of its two siphons. The water circulates over the gills and is filtered for microscopic food. It is then expelled from the other siphon.
Large geoducks live about 15 years and can reach 12 pounds. They are good for eating but the effort to dig them out discourages many collectors. It is usually much easier to gather smaller clams that have shallower habitats.
