Scattered along the seafloor, dense clusters of large metal lumps have been discovered by scientists trolling for deep-sea creatures between South America and Africa
The R/V Sonne, a German research ship, was several hundred miles east of Barbados when a mesh net meant to capture marine life instead brought up balls of manganese ore that were bigger than softballs. A remote camera later revealed that the seafloor was littered with these round manganese nodules, some the size of bowling balls.
"I was surprised, because this is generally not the place you think of for manganese nodules," said Colin Devey, chief scientist for the expedition and a volcanologist at the GEOMAR Helmholtz Centre for Ocean Research in Kiel, Germany.
The origin of manganese nodules also remains a mystery. Popular ideas include chemical reactions in seawater that are boosted by microbes, similar activity at underwater hot springs and the precipitation of excess metal from seawater.

I read about those the other day, they are rather fascinating, probably some perfectly normal cause though odd that they are more spherical than normal.
There must be all sorts of bizarre formations, creatures and things miles under the sea.
