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. Excessive barnacle cover can be a sign of general bad health of a turtle.
Commonly called Seb-Ks, or Skin Barnacles. This is one of the most common noncancerous skin growths in older adults. Seb-Ks usually start to appear as slightly raised, skin colored or light brown spots. With time, they start to thicken and develop a rough, waxy, scaly, warty texture.
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. They are also a food source for these animals.
Moving objects like boat and ship hulls and whales are particularly vulnerable to the pesky critters. Large barnacle colonies cause ships to drag and burn more fuel, leading to significant economic and environmental costs.
Do barnacles have brains? The neuropil of the brain includes protocerebral and deutocerebral divisions, with nerve roots from the protocerebrum extending to the eyes and frontal filaments, and nerve roots from the deutocerebrum extending to the first antennae (antennules) and cement glands.
Believe it or not, barnacles are edible and delicious! That's right, these creatures, commonly considered to be pests of the sea, can be harvested and prepared like any other seafood (provided they're the right kind, of course).
No, barnacles are not vegan. Barnacles are a type of shellfish, a marine animal that must be killed in order to produce barnacles for food consumption.
adult barnacles do have an eyespot. It is a third eye that occurs in the middle of their crustacean foreheads and aligns their arthropods selves with a cosmic energy.
The northern rock barnacle's hard outer shell is very sharp and can cause cuts or scrapes on bare feet and legs of human beachgoers. They are considered a nuisance by boaters, since they often attach themselves to boat bottoms, mooring lines, lobster and fish pots, and pilings.
These tiny holes are made by the tiny drilling 'tongues' of carnivorous sea snails. The culprits are likely to be dog whelks, whelks and necklace shells (more about them here) and they drill through the shells to get to the soft bodies inside which they turn to goo and suck up.
Sacculina is a genus of barnacles that is a parasitic castrator of crabs. They belong to a group called Rhizocephala.
Plus, people generally don't eat the parts where the barnacle hangs out. “In general, the parasite stays in the body cavity,” Sloan said. “It doesn't go out in the legs, so the crab's meat is probably perfectly fine to eat.”
Which parasite has the weirdest way of life?

Roundworm. These are the largest of the intestinal nematodes affecting humans, growing to 15-35 centimetres in length. They are transferred by ingestion. The eggs hatch and quickly penetrate the intestinal wall, where they enter the bloodstream.
The crustacean Cymothoa exigua has the dubious and unsettling honor of being the only parasite known to replace an organ. It enters through the gills of the spotted rose snapper, attaching to the base of the fish's tongue, where it drinks its blood.
It is estimated that around 80% of both adults and children have parasites in their gut. People can be infected with these parasites in a number of ways. The most common route is through the faecal oral route.
, either intentionally or accidentally, in contaminated food or water. In these cases, worms have been found in the mucosal tissues of the lips, cheek, tongue, tonsils, gums, and occasionally esophagus.
No, not really. Instead, they have cells called receptors that can sense whether it's light or dark. This allows worms to tell if they're underground or above ground.
The larvae typically make their way down to your stomach or intestines. There they can cause inflammation or damage. You can also have allergic reactions to these worms. Rarely, the larvae can stay in your throat area and that's when you may develop “tingling throat syndrome” and potentially a cough.
Sometimes adult worms can be seen moving under the skin. High numbers of blood cells called eosinophils are sometimes found on blood counts. Some people who are infected for many years may develop kidney damage though development of permanent kidney damage is not common.
