Coronulidae
Coronulidae is a family of barnacles, commonly known as whale barnacles. They are characterized by their distinctive shell morphology, which includes a conical base and a series of radiating plates that form a crown-like structure around the opening of the barnacle’s body. These barnacles are obligate parasites that live exclusively on whales and other large marine mammals.
Characteristics
Coronulidae are characterized by their:
- Conical shell
- Crown-like structure formed by radiating plates
- Pedunculate base, attaching to the host
- Small size, typically less than 2 cm in diameter
- Filter-feeding lifestyle
Environment
Coronulidae barnacles are found exclusively on the skin of whales, dolphins, and other large marine mammals. They are typically attached to areas where the host's skin is exposed to a high flow of water, such as the back, flippers, and head. The barnacles are highly adapted to life in this environment, with their shells providing protection from predators and their filter-feeding mechanisms allowing them to capture food particles from the water.
Common Names
Coronulidae barnacles are commonly referred to as "whale barnacles" due to their primary hosts. Some species may have specific common names, such as the "common whale barnacle" (Coronula diadema).
