pictures below.
Tracy in the foreground, Todd and Vicke in the background.
Semibalanus balanoides cyprids and metamorphs. The
cyprids are about 1mm long. The older barnacle in the upper right is
Chthamalus.
The name of this permanent quadrat is "the little friends" or
"les petits amis". This spot is where we first observed cyprids in early
January 2001, and we have been revisiting our little friends ever since. You
can see Semibalanus balanoides cyprids, metamorphs and juveniles. The
older two barnacles in the center left are Chthamalus.
Semibalanus balanoides metamorph about 1 mm in maximum
length. A metamorph is a barnacle that metamorphosed from cyprid within the
last 3-4 days. After 3-4 days the metamorphs start to produce a visible
whitish calcareous shell (see the pictures above)
Semibalanus metamorphs and cyprids. Late
February, 2002. The red button is a bee tag.
Semibalanus balanoides: cyprids, metamorphs and young
