THE SYMBIOTIC RELATIONSHIP BETWEEN A WHALE AND BARNACLES by Victoria Hulev on Prezi
Burdocks. Commensalism is much more difficult to demonstrate than mutualism. For true For example in the barnacle example, the scallop appears to be unaffected. However Barnacles attach to rocks, ships, shells, whales, and just about. Commensalism is a relationship between two organisms where one receives a benefit or Barnacles - These will attach to whales or mollusk shells in order to be These examples of commensalism in action show the symbiotic relationship . Oct 27, THE SYMBIOTIC RELATIONSHIP BETWEEN A WHALE AND Filter-feeding barnacles are the type that engage in symbiotic relationships with whales. Barnacles on some types of whales have a commensalism.
Before explaining the specific nature of their symbiotic relationship with marine birds, Trull helped to give us a better understanding of Humpback Whales.
In their animal classification, they are of the order Cetacea, suborder Mysticeti.
Symbiotic Relationship Between Humpback Whales and Marine Birds Presentation Recap
These whales spend summers in the cooler waters near the Cape and winters in more tropical areas. Another interesting fact Trull provided is that these whales, being mammals with lungs similar to ours, are unlike humans in that they are voluntary breathers.

Humpback Whales feed primarily on sand eels also known as sandlancesthis food source is what leads to their interesting relationship with marine birds. To better illustrate this relationship, Trull outlined the three types of symbiosis: If you think of mutualism as mutually beneficial, and parasitism as one benefitting at the cost of the well-being of the other, commensalism falls right in between.
Commensalism is a type of symbiotic relationship where one species will benefit while not affecting the other species in a positive or negative way. The relationship between Humpback Whales and marine birds is an excellent example of commensalism.
How Do Barnacles Attach to Whales?
Humpback Whales will consume up to 1 ton of sand eels every day. When a large school of these fish is located near the surface of the water, the whales will then rise up with their mouths agape and take in mouthfuls of them.
This method is particularly effective for the whales to consume the food they need to survive, but it also benefits other species as well. Although some barnacles are parasites, most are filter feeders.
Whale barnacle - Wikipedia
Filter-feeding barnacles are the type that engage in symbiotic relationships with whales. In biological terms, symbiosis is broadly defined as a close, extended relationship between two or more members of different species that benefits at least one member. There are three types of symbiosis.
In mutualism, both species benefit from the relationship. In parasitism, only one species benefits from the relationship and causes significant harm to the other.

Commensalism, in which only one species benefits without causing significant harm to the other, is the type of symbiosis between barnacles and whales. Cementing the Relationship Barnacles begin their lives as free-swimming larvae, progressing through six larval stages.
When they reach the last, or cyprid, stage, they settle onto the skin of a whale, where they complete their metamorphosis into juvenile barnacles. The juveniles -- tiny creatures resembling shrimp -- secrete cement that hardens into the hard, calcareous plates that surround them throughout their entire lives. As the cement plates meld together, the whale's skin is pulled into the spaces between the plates, permanently fusing the barnacles to the whale.
A Whale of a Ride For the entirety of the barnacles' lives they'll exist as diminutive hitchhikers on the backs and bellies of whales. They derive two basic benefits from this commensalistic relationship. As filter feeders, they depend on the availability of plankton, which they filter into their bodies through feather-like appendages extended through holes in their shells.
