Where
seen? These large cockles are sometimes seen on some of
our shores. These animals usually burrow shallowly in sandy to muddy bottoms.
What are true cockles? True cockles
belong to Family Cardiidae. There about 200 species of true cockles.
These include the magnificent Giant
clams in subfamily Tridacninae.
Features: 5-7cm. The two-part
shell is sturdy and usually ridged. The hinge has two strong teeth
in each valve. They have a short fringed siphon and can
use their long, strong, sickle-shaped foot to jump and escape predators.
Human
uses: They are collected for shell craft and sometimes
eaten by coastal dwellers. |
