Why do whales have barnacles?
In the case of barnacles and whales, only the barnacles benefit from attaching to the whales , but at no biological cost to the whale. This type of symbiotic relationship is known as commensalism. In this case, attaching to the whales gives the barnacles a stable place to live, a free ride, and access to plenty of food.

Do whales have periods?
Females come into estrus several times during the year. Observations of females in zoological parks indicate that killer whales undergo periods of multiple estrous cycling (polyestrus), interspersed with periods of noncycling. On average, females may have four estrous cycles during one polyestrus period.
Hippos and whales may look different in many ways, but they are actually each others’ closest living relatives —sharing a common ancestor that lived about 55 million years ago. ... Learn more about the ancient land mammal known as “the first whale.”

Because they are filtering organisms , they play an important role in the food chain. Barnacles are suspension feeders, consuming plankton and dissolved detritus suspended in seawater and are therefore essential in cleansing that water for other organisms.
Do whales have parasites?
Parasites like tapeworms infect the digestive tracts of their hosts, absorbing valuable nutrients from the host’s meal. Just like people, whales can have tapeworms. The largest tapeworm in the world was found in a whale, and measured over 30 metres long!
