Tinea nigra, also known as superficial phaeohyphomycosis and Tinea nigra palmaris et plantaris, [2] is a superficial fungal infection, a type of phaeohyphomycosis rather than a tinea, that causes usually a single 1–5 cm dark brown-black, non-scaly, flat, painless patch on the palms of the hands and the soles of the feet of healthy people.

Barnacle adults are sessile; most are suspension feeders with hard calcareous shells, but the Rhizocephala are specialized parasites of other crustaceans, with reduced bodies. Barnacles have existed since at least the mid-Carboniferous, some 325 million years ago. In folklore, barnacle geese were once held to emerge fully formed from goose ...
The geochemistry of barnacle shells provides clues as to where the barnacles have traveled. The barnacles attached to the already-recovered Malaysian Airlines Flight 370 debris offer up partial clues.
Tinea manuum is a fungal infection of the hand, mostly a type of dermatophytosis, often part of two feet-one hand syndrome. [2] [4] There is diffuse scaling on the palms or back of usually one hand and the palmer creases appear more prominent. [2]
L. panopaei manipulates the behaviour of both sexes of the crab on which it settles, so that the host treats the barnacle's brood sac as if it contained the crab's own eggs. In the case of male crabs, the parasite causes the ventral abdominal plate to widen, which makes it more suitable for brooding, and alters the crab's behaviour so that it ...
They have the science to back up their faith in the barnacles, too. When the flaperon piece of MH370 washed ashore on Reunion Island in July of 2015, it was covered with the barnacle Lepas ...

Rhizocephala are derived barnacles that are parasitic castrators. Their hosts are mostly decapod crustaceans, but include Peracarida, mantis shrimps and thoracican barnacles. Their habitats range from the deep ocean to freshwater. [1] [2] Together with their sister groups Thoracica and Acrothoracica, they make up the subclass Cirripedia. [3]
