Although some barnacles are parasites, most are filter feeders. Filter-feeding barnacles are the type that engage in symbiotic relationships with whales. C. All other choices are examples of symbiosis, a relationship in which whales and barnacles, the barnacle attaches itself to the whale, getting both of chromosomes would be an indicator to a genetic counselor if an abnormality occurs. Barnacles live on the surface of the whale and eat food that passes around " The Symbiotic Relationship Between a Barnacle Living on a.
His candidacy was reviewed by a multidisciplinary team of surgeons, physicians, psychiatrists, social workers, and nurse coordinators. After appropriate donor identification and recipient induction with antithymocyte globulin, allograft procurement and recipient preparation took place concurrently.
Anastomoses of the urethra, corpora, cavernosal and dorsal arteries, dorsal vein, and dorsal nerves were performed, and also inclusion of a donor skin pedicle as the composite allograft.

Maintenance immunosuppression consisted of mycophenolate mofetil, tacrolimus, and methylprednisolone. Intraoperative, the allograft had excellent capillary refill and strong Doppler signals after revascularization. Operative reinterventions on postoperative days PODs 2 and 13 were required for hematoma evacuation and skin eschar debridement. At 3 weeks, no anastomotic leaks were detected on urethrogram, and the catheter was removed.
At 7 months, the patient has recovered partial sensation of the penile shaft and has spontaneous penile tumescence. Our patient reports increased overall health satisfaction, dramatic improvement of self-image, and optimism for the future. We have shown that it is feasible to perform penile transplantation with excellent results. 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.
Symbiotic Relationship: Barnacles on Whales by Olivia Hartman on Prezi
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. When the whales swim into plankton-rich waters to feed, so do the barnacles.
