While barnacles don’t physically harm whales, their presence can cause great harm to these marine mammals. Do barnacles hurt whales? When barnacles attach to a whale’s skin, they create drag, which could make the whale less efficient in the water. This may result in a higher metabolic cost as the whale swims.
Though small barnacle infestations would not hurt the whale, if they were large they would be irritating and damaging, particularly if they grew in sensitive areas. Barnacles aren’t doing direct harm, but they can be another source of stress on a whale’s often tired body. This is particularly true during migration or feeding.
Knowing more about the relationship between barnacles and whales is a great first step to understanding marine ecosystems’ complex dynamics.

Key Takeaways
- Barnacles, and whale lice in particular, anchor themselves to whale skin using a powerful adhesive cement. This attachment can really hinder the whales’ mobility and swimming efficiency.
- Extreme cases of barnacle infestations may result in pain, skin damage, stress, and behavioral alterations for whales.
- Whales rub themselves against the seafloor or other surfaces to alleviate irritation from barnacles, suggesting a level of sensitivity to their skin.
- Overgrowth of barnacles can restrict a whale’s ability to feed, as added drag would necessitate more energy expenditure, possibly resulting in lower feeding rates.
- Barnacles are largely considered harmful invasive species and nuisances. They act as nurseries for many marine species and increase biodiversity.
- The nebuluous relationship between barnacles and whales. This interaction is not only harmful and detrimental to whale health and behavior, it has a substantial impact on the dynamics of our oceans.
Understanding Barnacles and Whales
Barnacles, specifically whale barnacle species, are highly specialized marine crustaceans, members of the class Cirripedia, with more than 1,000 species described. These marine invertebrates have an incredible symbiotic relationship with feeding whales, frequently latching onto the skin of these colossal mammals. This interaction is commonly understood as an obligate form of commensalism, where the barnacles benefit while the whales remain mostly neutral.
What are barnacles and how do they attach to whales
Barnacle larvae begin their life cycle as free-floating plankton. They drift around looking for the right surface, such as a whale’s skin, where they can attach and mature. Once they find a home, they grow into adult bodies that are sessile, or permanently attached.
Environmental factors, like water temperature and salinity, play a role in how long barnacle larvae stay in the water column before settling. The truly amazing adhesive properties of barnacle cement are such that they are able to bond to a surface as dynamic and complex as whale skin. The most common barnacle species found on whales are acorn barnacles and whale lice.
How barnacles affect whale mobility
Large barnacle clusters add significant drag to a whale’s body, impacting how efficiently it can swim. This extra mass makes it harder for whales to stay energy efficient while swimming. Eventually, whales would have to evolve new physical characteristics to meet this drag head-on.
These adaptations allow them to migrate and feed more efficiently.
Are barnacles itchy for whales
Although barnacles are not directly harmful, infestations may lead to pain or irritation. To relieve this itchiness, whales frequently rub against hard surfaces, like the hulls of ships, which can seriously affect their behavior.

Whale barnacles could live upwards of a year and most frequently slough off while their whale hosts are migrating or calving. Whales are just so large that they can host these huge barnacle colonies that weigh almost a ton.
Effects of Barnacle Infestations on Whale Health
Barnacle infestations, particularly from whale barnacle species, can be detrimental to a whale’s overall health, creating a myriad of health threats. When severely infested, these marine crustaceans can cause significant skin irritation, leading to stress and behavioral changes. In addition to blocking the whales’ beauty, barnacles can upset the already fragile balance of whale skin health, making it increasingly difficult for these magnificent creatures to survive.
Do barnacles hurt whale skin
Whale skin can be damaged by barnacles. They can even burrow in deep, creating welts that can welcome in infections. A single humpback whale can be transported around almost 1,000 pounds of barnacles. That’s equivalent to factoring in the weight of summer clothes for a person!
The consequences of these injuries can be dire, compromising the whale’s long-term health and survival. Barnacles such as barnacle goose or the acorn barnacle represent a more serious danger due to their intensive adhesion. Whales do have natural skin-care mechanisms, such as rubbing against hard surfaces, but severe infestations can exceed those natural defense efforts.
Impact on whale feeding habits
Heavy barnacle infestations might prevent a whale from feeding in any efficient way. The added drag created by barnacles has an effect on swimming efficiency, requiring whales to use more energy while foraging. This additional energy expenditure may be worst case as feeding frequency decreases.
Species such as the bottom-feeding gray whale would be further impacted as barnacle growth increases.
Influence on whale behavior and social interactions
Additionally, barnacle infestations may change social interactions within and between whale pods. They can interfere with reproductive behaviors and calf rearing. Barnacles can affect everything from migration patterns to social structure.
Examples of behavioral changes that have been documented are increased agitation, decreased social interactions, and possible changes in communication.
- Surface abrasion from increased scratching
- Alterations in movement behavior
- Decreased socialization
- Changes in feeding behavior
Ecological Role of Barnacles in Marine Environments
Barnacles are an ecological keystone species, forming a mutually beneficial attachment to whales that truly embodies nature’s symbiotic connection. This relationship is known as obligate commensalism. Barnacles have an ecological win on their hands, hitching a ride on whales as the whales themselves go unbothered.
Note barnacles here growing attached to the skin of whales. This affords them both access to more nutrient-rich waters and increased mobility, two things that help them flourish in constantly changing landscapes.
Contribution to Marine Biodiversity
Barnacles are important substrates for other marine organisms. Their hard shells create homes for many small fish, crustaceans, and other invertebrates, increasing biodiversity.
As filter feeders, barnacles feed on plankton and are, in turn, eaten by a variety of marine organisms. Barnacles go on to serve an important role in the food web. They are used as indicators of marine ecosystem health, showcasing the delicacy of the balance of their communities.
Some species that rely on barnacles include:
- Small fish like blennies
- Sea anemones
- Various crustaceans
Impact on Whale Populations and Ecosystems
Barnacle infestations may have implications for whale population dynamics. The additional weight and drag on whales can lead to an increased energetic cost.
It’s more on the order of having to wear summer clothes, so it doesn’t impose much of a cost. Barnacles are indicators of environmental changes, warning us of where whales’ habitats are moving.
A further decline in whale populations would put barnacle ecosystems in jeopardy, a testament to the interdependence of these animals.
Relationship with Other Marine Species
Barnacles play an important role in the ecology of marine species, as both predators and competitors. Their role as ecosystem engineers greatly affects biodiversity in the marine environment, in turn adding to the complexity of the food web.
They change the biophysical health of other organisms by changing habitat structures. Key marine species that share ecological relationships with barnacles include:
- Sea turtles
- Fish species like parrotfish
- Various mollusks
Do barnacles hurt whales? Final Words
Barnacles don’t just hitch a free ride on whales. Though they are hugely important in marine ecosystems, they are hugely detrimental to whale health. To make sense of the barnacle-whale dynamic takes us into an extraordinary world, where strange creatures thrive as tag-along hitchhikers and opportunistic travelers. Although whale health can be adversely affected by extreme barnacle loadings, this symbiotic interaction illustrates the harmony found within the ocean’s balance.
Understanding the needs of both species provides valuable lessons for future conservation efforts.
