Whale barnacles are species of acorn barnacle that belong to the family Coronulidae. They typically attach to baleen whales, and sometimes settle on toothed whales. The whale barnacles diverged from the turtle barnacles about three million years ago. Whale barnacles passively filter food, using tentacle-like cirri, as the host swims
Barnacles and limpets compete for space in the intertidal zone. Barnacles are displaced by limpets and mussels, which compete for space. [7] They employ two strategies to overwhelm their competitors: "swamping", and fast growth.

With some species of whale louse, whale barnacle infestations play an important role. On the right whale, the parasites live mainly on callosities (raised callus-like patches of skin on the whales' heads). The clusters of white lice contrast with the dark skin of the whale, and help researchers identify individual whales because of the lice ...
The scientists found large whales such as humpbacks and North Atlantic right whales were among the most vulnerable to climate change, and that other toothed whales and dolphins were also at high risk.
The tourists encountered two humpback whales during the Nov. 8 trip, one of which was extra “friendly,” according to a Facebook post from Monterey Bay Whale Watch. The humpback was intrigued ...
Blainville's beaked whales do not capture prey by biting. They use suction feeding to capture prey. They create low pressure in the mouth by retracting tongue, and using throat grooves to expand throat volume. This creates a lower pressure in the mouth than the surrounding waters, allowing the whale to suck in water and whole prey. [12]
