“…The longest time to metamorphosis in the nonfreezing and freezing treatments was 26 and 38 d for the attached cyprids, and 77 and 89 d in the loose metamorphs. Lucas et al (1979) calculated an energy budget for S. balanoides cyprids and concluded that cyprids would lose their competence to metamorphose successfully at 21-28 d. Lucas et al (1979) used captured cyprids, where age was unknown and therefore 21-28 d might underestimate the maximum competency period. Lucas et al (1979) experiments were conducted at 10ЊC, which is generally warmer than in our experiments, where 10ЊC was reached in late April.…”

Barnacle larvae in ice: Survival, reproduction, and time to postsettlement metamorphosis

2005

Late stage larvae (cyprids) of the barnacle Semibalanus balanoides frequently encounter freezing conditions along the northwest Atlantic coast. S. balanoides cyprids survived for more than 4 weeks embedded in sea ice, and a significant fraction of larvae held in ice up to 2 weeks successfully settled and metamorphosed after thawing. Larvae that completed metamorphosis continued to develop and reproduce. In settlement experiments with cyprids of known age and where settled cyprids were removed every other day from the experimental containers, cyprids held in ice for 2 weeks settled and metamorphosed more than nonfrozen larvae. Mean time to metamorphosis was longer for frozen cyprids than for nonfrozen ones, and maximum time to metamorphosis was 38 d for cyprids held in sea ice for 2 weeks and 26 d for cyprids in nonfrozen treatments. Larval tolerance to freezing conditions greatly expands the environmental tolerance repertoire of marine invertebrates and may help explain the ecological success of this widespread intertidal species.

“…A slower sinking rate would reduce energy costs of swimming to maintain optimal depth. This saving in energy should allow a longer search for a suitable substrate (Lucas et al, 1979). In contrast, the di¡erences between the species in the appendages and their setation are small and minor.…”

Larval development of the intertidal barnacles Chthamalus stellatus and Chthamalus montagui

1999

Two recently-distinguished species of Chthamalus (Cirripedia) are found on rocky shores in the northeastern Atlantic: C. stellatus predominant on islands and headlands and C. montagui more abundant in bays. Larvae of the two species were produced in laboratory cultures to describe and compare the morphology and to allow identi¢cation in plankton samples. Nauplius larvae of C. stellatus are up to 30% larger than those of C. montagui. Di¡erences in setation are minor. The two species are easily distinguishable from the size and shape of the cephalic shield. Chthamalus stellatus has a subcircular shield with longer body processes in later stages while C. montagui is more ovoid. The former develop more slowly in culture than the latter. Chthamalus stellatus larvae in a culture at 19 8C reached stage VI in 16 d compared to 11 d for larvae of C. montagui at the same temperature. The morphology and longer development time of C. stellatus larvae suggests adaptation to a more oceanic lifestyle and wider dispersal to reach more fragmented habitats than larvae of C. montagui.

“…Previous studies by Anil (1991) reported that barnacle larvae hatched from adults collected during late autumn to early spring were characterized by poor development capability compared to those collected in summer months in the Hamana Bay of Japan. In barnacle Balanus balanoides, the total length of the pelagic life depends mainly on the initial neutral lipid levels (Lucas et al 1979). Generally, the duration of embryonic development is closely related to the inter-moult cycle in barnacles (Fyhn, Costlow 1977).…”

Barnacle Amphibalanus amphitrite adults were collected from the Jeddah coast of the Red Sea during different seasons. The nauplii released by adults in autumn, winter, spring and summer were reared under laboratory conditions to know the larval development duration and settlement in relation to the hatching season. The nauplii reared during winter (11 days) and autumn (13 days) took longer to reach the cypris stage compared to nauplii reared in summer (6 days) and spring (7 days). The most successful settlement of larvae was observed in spring and summer and the least successful − in winter. The observations of gonads showed that summer and spring are the active breeding season for A. amphitrite in the Red Sea. The results of this study indicated that the nauplii hatching season plays a significant role in the larval development and settlement of barnacles in the Red Sea.
