Gromia (original) (raw)
Gromia ist eine Gattung amöbenartiger Einzeller, die sowohl im Meer- als auch im Süßwasser zu finden sind. Sie werden in der näheren Verwandtschaft der Foraminiferen (Foraminifera) angesiedelt und stellen wahrscheinlich deren Schwestergruppe dar.

| dbo:abstract | Gromia ist eine Gattung amöbenartiger Einzeller, die sowohl im Meer- als auch im Süßwasser zu finden sind. Sie werden in der näheren Verwandtschaft der Foraminiferen (Foraminifera) angesiedelt und stellen wahrscheinlich deren Schwestergruppe dar. (de) Gromia es un extenso género de ameboides marinos y de agua dulce, semejantes en forma a algunos foraminíferos. Producen una testa orgánica, ovoide o lobulada que puede exceder de un milímetro de tamaño. Los filopodios emergen de una sola abertura en la testa. Se ramifican y pueden combinarse entre ellos, pero, al contrario de los seudópodos de los foraminiferos verdaderos, no son granulares y forman raramente una red. El ciclo vital implica la reproducción asexual y sexual, y en ciertas etapas se producen células móviles con dos flagelos. En los árboles moleculares, Gromia se separa de las otras amebas filosas que forman la base de Cercozoa, y aparece entre Cercozoa y Foraminifera. Podría ser considerado como el pariente vivo más cercano de los foraminiferos, pero esto es difícil de confirmar debida a la rápida divergencia genética de estos grupos. En este grupo se encuentra la especie Gromia sphaerica, el cual es el ser unicelular más grande conocido. (es) Gromia is a genus of protists, closely related to foraminifera, which inhabit marine and freshwater environments. It is the only genus of the family Gromiidae. Gromia are ameboid, producing filose pseudopodia that extend out from the cell's proteinaceous test through a gap enclosed by the cell's oral capsule. The test, a shell made up of protein that encloses the cytoplasm, is made up of several layers of membrane, which resemble honeycombs in shape — a defining character of this genus. Gromia were first discovered in shallow waters, with members of the best-characterized species often found inhabiting rock surfaces, sediments, or seaweed holdfasts. However, research from the 1990s and early 2000s identified gromiids inhabiting depths up to 4,392 m, leading to several new deep-sea Gromia species being described and recognized. A recent study of the deep sea species Gromia sphaerica revealed that it produces traces on the seafloor which resemble fossil traces formerly attributed to early Bilateria (animals with bilateral symmetry); this now calls into question whether such fossil traces are reliable as documentation of early multicellular animal diversification in the Precambrian era. Deep-sea gromiids have also been shown to be important for carbon cycling and denitrification.
