Habitat and distribution
Can be found in the Mediterranean Sea. The colonies are anchored to rocky substrates, often characterized by coralligenous, in shaded areas from 1-2 meters and up to 100 meters deep.
The colony, up to 10 cm wide, has dichotomous ramifications, short and squat, porous, of intense red-orange color, with a cylindrical section, which appear truncated at the ends. Unlike the true coral polyps, which are white, the polyps of this species have the same color as the ramifications.
The study of the diameter of the branches and the size of the polypoid, variable according to the environmental conditions, led to consider M. truncata as an environmental indicator of the changes that occurred between the Cenozoic and the modern era in the Mediterranean Sea.
Reproduction takes place between February and March.
