It has a strong head, long and raised horns, a narrow chest, a high-set tail, clear joints, and slender limbs.

"This text specifies the original ethnic background of a breed within the blond bovine group in the southwest with pink mucous membranes.

This differs from the high lyre-shaped horns with tips brought back, which are typical of other bovines in the Pyrenean group.

The old photos below illustrate the composite nature of the origins of the current animals in their environmentMarine cattle farming has long history of being extensive.

Their instincts lead them to reach the dunes that are on the edge of the sea, all along the coast of the Médoc, Pays de Buch, Born, and Marensin.

As the dunes stabilized in Aquitaine in the 19th century and the Landes de Gascogne was colonized by maritime pine, the semi-marshy shores of the ponds became the refuge for these herds.

This extensive semi-wild state of husbandry practices is also observed in the mountainous lands of the neighboring Basque Country, where the Betizu cattle, another variant of the blond Pyrenean branch, has a population that had preserved the original characteristics of its coat due to minimal crossbreeding.

Young "coupes" (plots recently planted with pine trees) were carefully monitored to prevent damage caused by cows.

[2] World War II marked the end of the bovine: the German army and the people of the Landes decimated the marine cows.

As can be seen above, these were not the original Landais cows that disappeared but were descendants of them after crossbreeding with animals of the Bretonne Pie Noir and Brava breeds.

[6] It is not officially recognized in the list of French breeds, but the gene pool of these animals should be preserved due to their adaptation to a natural life in wetlands.

The preservation and maintenance of the Marine Landaise by a nature protection society, SEPANSO, in collaboration with the Landes hunters' federation, determine the implementation of the current breeding method: conservation grazing.
