They don't harm the whales or feed on the whales, like true parasites do. Barnacles don't serve any obvious advantage to the whales, but they give helpful lice a place to hang onto the whale without getting washed away by water. Barnacles find the slow-swimming gray whale a good ride through nutrient-rich ocean waters.
Do whales get lice?
Whale lice are orange colored patches around the barnacles and in crevices of the whale’s body such as creases and the mouth line. To get rid of the whale lice, whales rub themselves along the sea bottom or breach. Gray whales feed on bottom sediments and scrape off barnacles and whale lice as they feed.
How do whale lice live in barnacles?
Sometimes whale lice squeeze themselves into the space between the shell and the actual body of the whale barnacle. This can create a tight living quarters and might lead to attack by a few whale lice upon the host barnacle. But generally the whale lice simply use the inside of the barnacle shell as shared living accommodations.
How do whale lice help heal wounds?
The whale lice move to the wound and eat the wounded flesh, thus keeping that healing flesh from getting infected. This is a 3 way beneficial relationship with all three benefiting from one of the others.
Why do whale lice have hooks?
The lice have small hooks to cling on to the whales’ callosities, which are crusty growths made of the whale itself, barnacles and Caprellids amphipods. On the callosities there are about 5000 Cyamus ovalis which gives them the white color. Between the callosities there are about 200

How do whales get rid of lice?
Whale lice are orange colored patches around the barnacles and in crevices of the whale's body such as creases and the mouth line. To get rid of the whale lice, whales rub themselves along the sea bottom or breach. Gray whales feed on bottom sediments and scrape off barnacles and whale lice as they feed.
Are whale lice harmful to humans?
The lice predominantly eat algae that settle on the host's body. They usually feed off the flaking skin of the host and frequent wounds or open areas. They cause minor skin damage, but this does not lead to significant illness.
What eats barnacles off whales?
Living upon the back of a Gray Whale means they are free from attacks by the most common enemies of the various barnacle species. Stationary barnacles are regularly attacked and eaten by sea stars (starfish), sea cucumbers, some sea worms, as well as various snails and whelks.
What is the natural predator of lice?
Introduce natural predators (Ladybugs) Ladybugs can eat 100 lice a day!
What are orcas afraid of?
Selbmann says that in the majority of the interactions documented around Iceland, killer whales seem to avoid pilot whales. Occasionally things will get heated and the pilot whales will chase the killer whales at high speeds, with both species porpoising out of the water. Don't miss what matters.
Why do orcas not get barnacles?
They can swim up to 35 mph in short bursts and can easily have a normal traveling speed of 5–7 knots. Also, their skin is smooth like a dolphin's, not bumpy or coarse like the skin of many whales. All of these things prevent orcas from getting barnacles.
Can barnacles grow inside humans?
Yes, barnacles can grow in human flesh.
Are whale lice itchy?
The sensation of itchiness is generally thought to help an animal locate something on its skin that shouldn't be there, such as an insect. In the case of marine mammals, the issue isn't insects, but rather various parasites such as whale lice or barnacles.
Do barnacles attach to sperm whales?
Barnacles are rather uncommon on sperm whale teeth, as they can usually fully close their mouths. But they are very common on the teeth of certain beaked whales, which have their tusks always exposed.
Do barnacles hurt the animals they attach to?
Most barnacles do not hurt sea turtles as they are only attached to the shell or skin on the outside. Others though burrow into the skin of the host and might cause discomfort and provide an open target area for following infections.
Do barnacles need whales to survive?
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.
Can the ocean get rid of lice?
It is unlikely, as ocean water does not have a high enough concentration of salt nor does it provide a proper delivery method to effectively kill head lice and nits.
How do whales get lice?
Unlike barnacles, whale lice can only be transferred between animals through bodily contact. They attach themselves to a whale's skin using hooked legs called dactyli. These legs look similar to those of human louse, which is exactly where they got their name from.
Does the ocean help with lice?
Parents need to realize that the bright sunlight that is abundant at the beach does not kill lice. In fact, they thrive in an environment that includes heat and humidity. Also, they can hold their breath for up to four hours, so don't count on that ocean swim killing them.
Do lice live on whales?
In addition to a whale's skin folds, lice may live around the rough, whitish patches called callosities, or in a whale's throat grooves, or even in the spaces between barnacles attached to a whale's skin. Whales can carry three or more species of lice at once, each carving out its own territory.
Where do Cyamus boopis live?
In contrast, individuals of the Cyamus boopis species, a few of which I could just discern in this photo of a humpback raising the tip of its rostrum above the water in Alaska, make their home only on Megaptera novaeangliae.
Do whale lice stick to whales?
In other words, whale lice stick to certain whales.
Is whale lice a parasite?
I learned a number of things in the process, like the fact that whale lice aren’t lice per se, though they are parasites, just like their namesakes. Whale lice are actually amphipods…tiny crustaceans…that make their living on their host cetaceans.
Do barnacles eat whales?
As an aside, it’s worth noting that unlike whale lice, barnacles don’t feed on the whales. They’re more like hitchhikers, using whales for transport while filtering the water for food. So barnacles are not parasites per se, but could perhaps more accurately be described as commensal organisms, for those of you who might care about the distinction.
Is a barnacle a cetacean?
Turns out, barnacles are cetacean-species-specific as well.
Do parasites pick off dead skin?
For sustenance, they pick off pieces of dead skin and flesh. In normal situations, population of these parasites seem to stay in check, thereby not hurting their large hosts (and homes).
How long is a whale louse?
Its length ranges from 5 to 25 millimetres (0.2 to 1 in) depending on the species.
How many lice are there on a whale?
Around 7,500 whale lice live on a single whale. 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).
What do white lice eat?
The lice predominantly eat algae that settle on the host's body. They usually feed off the flaking skin of the host and frequent wounds or open areas.
Where do whale lice live?
Whale lice attach themselves to the host body in places that protect them from water currents, so they can be found in natural body openings and in wounds; with baleen whales they are found primarily on the head and in the ventral pleats. Around 7,500 whale lice live on a single whale.
Is sperm whale parasitic?
With the sperm whale, the parasitic relationship is sex-specific. The whale louse Cyamus catodontis lives exclusively on the skin of the male, while Neocyamus physeteris is found only on females and calves.
Do whale louses live with their host?
Most species of whale louse are associated with a single species of whale. They remain with their host throughout their development and do not experience a free-swimming phase. Although the relationship between a specific species of whale louse and a specific species of whale is more pronounced with baleen whales than with toothed whales, almost every species of whale has a louse species that is unique to it. With the sperm whale, the parasitic relationship is sex-specific. The whale louse Cyamus catodontis lives exclusively on the skin of the male, while Neocyamus physeteris is found only on females and calves.
Is a whale louse a cyamus?
Cyamus. Isocyamus. Neocyamus. Platycyamus. Scutocyamus. Sirenocyamus. Syncyamus. A whale louse is a commensal crustacean of the family Cyamidae. Despite the name, it is not a true louse (which are insects ), but rather is related to the skeleton shrimp, most species of which are found in shallower waters.
How do barnacles reproduce?
Marine biologists speculate that the barnacles reproduce during the whales’ breeding season, when the whales mill around in warm, shallow waters rather than moving through the open ocean. If that’s true, Zardus said, the whales would swim in a thick soup of larvae; each barnacle parent can release anywhere from 10,000 to 20,000 spawn, and they survive for several weeks in the water. When a whale does swim by, research suggests, the drifting larvae pick up a chemical signal that tells them to hop on.²
What is a whale bound barnacle?
Whale-bound barnacles aren’t just regular barnacles with wanderlust; they’re different species, most of them unique to the brand of whale they piggyback on. The barnacle Coronula diademalives only on humpback whale skin, for example, while gray whales host one called Cryptolepas rhachianecti.¹
Why are barnacles so scarce?
Research on whale barnacles is scarce, according to Zardus, because they’re not the easiest beasts to get a hold of. The larvae are small and difficult to distinguish from other kinds of barnacle larvae, and the adults are so deeply embedded in the skin of their hosts that they have to be carved out, flesh and all.
What happens if you sandblast a whale?
2) Sandblasting a whale or otherwise scooping out these barnacles would result in the death or severe injury of the whale. I have a whale barnacle shell sitting on my desk; it’s about two inches deep, and the very top of the shell is the only part that is exposed. It would be more like pulling teeth.
Why do people harm wildlife?
People harm wildlife and ecosystems every minute because they act based on how they feel or because they are anthropomorphizing the animals/plants involved. Whales are utterly unlike humans, and the only thing we really have in common is a degree of intelligence and endothermy. Whale skin is very thick and the barnacles are not causing harm.
Where did Mara Grunbaum study?
Mara Grunbaum studied English and environmental science at NYU. Before returning to New York, she worked for several years as a freelance reporter in Portland, Oregon, where she wrote about local politics, poverty and social justice. As a science reporter, she’s most interested in biology, ecology and most anything having to do with the ocean. You can also read her blogor follow her on Twitter.
Do barnacles and whales have a symbiotic relationship?
I know that it is a symbiotic relationship between endangered whales and the barnacles, but the thought that the barnacles could settle in places that could cause great harm to the whales causes me great distress, it definately seems like something out of science fiction!
How long do gray whales have barnacles?
The growing barnacle must molt several times, until after 6 to 10 months the adult barnacle is full grown. When we see baby whales, they have baby barnacles visible within days of being born. Thus if you see a baby whale with no barnacles around the blowhole or V of the tail, that baby is almost certainly less than a week old. I have been studying the lives of Gray Whales since 1994 and in all that time I have only seen one gray whale that did not have any barnacles. That whale was known as JJ, a rescued baby Gray Whale. JJ lived at Sea World in San Diego for one year. JJ probably lost contact with his mother at birth and thus never developed any barnacle clusters. Because he had no barnacles, he also had no gray or white patches of skin. JJ was the only black Gray Whale I have ever seen. Those of you who have traveled with me to Baja to see whales have heard the story of JJ. If you haven’t heard the tale, come along some time and ask to hear this story about one unique whale.
How long do barnacle eggs stay in the mantle?
The eggs are brooded inside the mantle of the barnacle for a short period of time. Brooding varies among barnacle species and can be up to several months duration. But we know that small barnacles are visible upon whales within days or weeks of their arrival in the lagoons.
What are the barnacles of a gray whale?

What is the name of the naupli that are released into the ocean?
The eggs develop into a form called nauplius or nauplius larvae. These naupli are released into the ocean where they are free swimmers and become part of the planktonic soup.
Where do whale lice come from?
Whale lice gather around open wounds or scars of the whale. Lice can spread from mother whales to their calves during birth, and nursing. Whale lice are orange colored patches around the barnacles and in crevices of the whale’s body such as creases and the mouth line.
What do gray whales eat?
Gray whales feed on bottom sediments and scrape off barnacles and whale lice as they feed. The photo is of Scarback taken this past summer at Whale’s Tail Charters; she is the most famous resident gray whale here in Depoe Bay. Scarback can be identified by the large scar on her right dorsal hump.
What are barnacle scars on whales?
Barnacle scars create a unique pattern on each whale, which can help in identifying the gray whale. Gray whales have whale lice which are not true parasites. They feed on the skin and damaged tissue which is beneficial to whales. Whale lice gather around open wounds or scars of the whale. Lice can spread from mother whales to their calves ...
How long do barnacles stay on a whale?
Barnacles stay on gray whales for as long as they are alive. Barnacles depigment the skin when they attach themselves to the whale. When the barnacles die and fall off, they leave a small round white circle or ring. Barnacle scars create a unique pattern on each whale, which can help in identifying the gray whale.
What are barnacles and whale lice?
Barnacles And Whale Lice. Scarback, Depoe Bay's most famous gray whale. Barnacles and whale lice are a fact of life for gray whales; there are hundreds of pounds of barnacles on gray whales. These barnacles attach themselves to gray whales in the lagoons when the whales are born. Barnacles stay on gray whales for as long as they are alive.
