I want to know: What is their trophic status and how they withstand the changing climate in the region they live?
planktonic larva of this species is unique in that when it settles out of the plankton it crawls around, searching for adults of its own species before attaching to a solid substrate. This explains why solitary gooseneck barnacles are rarely seen; even when there is empty space on the rock, there are always many gooseneck barnacles crowded together in clumps.
They have significance in Biofouling. Salinity and temperature are two important physical parameters that determine the distribution of organisms in the marine environment.. They have also evolved themselves to survive desiccation and respire by taking air into the mantle cavity. As there is marked reduction in metabolic activity during emersion, aerobic respiration has been found to satisfy nearly all their metabolic needs.
Berna or Barna? If it is Barna, then obviously as metal accumulator and biofouler
Every organisms has its own role in the ecosystem. All filter feeders help the environment to keep clean. These barnacles are big problem as fouling organisms to ships or ant structures in the Ocean, but it can filter the water to keep a healthy ecosystem.
