Pacific Gaper
Pacific Gaper
tresus nuttallii
The Pacific Gaper is a fascinating clam that burrows into the sandy ocean floor! Kids will love learning how it filters food from the water around it.
生息地: They live in sandy ocean bottoms along the Pacific coast.
外見
The Pacific Gaper has a large, thick shell, often dirty white or yellowish, that gaps open because its long, leathery siphon cannot fully retract. Its siphon tip can be orange or reddish, a key difference from similar clams.
