An autonomous underwater vehicle (AUV) for recording seismic signals during a marine seismic survey. The AUV includes a body extending along an axis X and having a head portion, a middle portion, and a tail portion, wherein the middle portion is sandwiched between the head portion and the tail portion along the X axis; a cross-section of the middle portion, substantially perpendicular on the X axis, having a triangular-like shape; the head portion including a base portion having the triangular-like shape and configured to match the middle portion; the head portion having a tip that, when projected along the X axis on the base portion, substantially coincides with a centroid of the base portion having the triangular-like shape; and a seismic payload located within the body and configured to record seismic signals.

1. An autonomous underwater vehicle (AUV) for recording seismic signals during a marine seismic survey, the AUV comprising: a body extending along an axis X and having a head portion, a middle portion, and a tail portion, wherein the middle portion is sandwiched between the head portion and the tail portion along the X axis;a cross-section of the middle portion, substantially perpendicular on the X axis, having a triangular-like shape;the head portion including a base portion having the triangular-like shape and configured to match the middle portion;the head portion having a tip that, when projected along the X axis on the base portion, substantially coincides with a centroid of the base portion having the triangular-like shape; anda seismic payload located within the body and configured to record seismic signals. 2. The AUV of claim 1, wherein the triangular-like shape includes a triangle for which all vertices are replaced with curved lines. 3. The AUV of claim 1, wherein the tail portion has a base portion having the triangular-like shape and configured to match the middle portion. 4. The AUV of claim 3, wherein a tip of the tail portion, when projected along the X axis on the base portion of the tail portion, coincides with a centroid of the triangular-like shape or is below the centroid. 5. The AUV of claim 4, further comprising: two engines and two corresponding propellers located in a plane that includes the tip of the tail portion. 6. The AUV of claim 5, wherein the plane also includes the tip of the head portion. 7.

The AUV of claim 1, wherein the head portion further comprises: three curved side faces, wherein the head portion has a tetrahedral shape with three faces of the tetrahedral shape being curved and corresponding to the three curved side faces. 10. The AUV of claim 9, wherein each of the three curved side faces is bent around two perpendicular axes. 11. The AUV of claim 9, wherein each of the three curved side faces is bent around only one axis. 12. The AUV of claim 9, wherein the three curved sides form a modified Releaux tetrahedron. 13. An autonomous underwater vehicle (AUV) for recording seismic signals during a marine seismic survey, the AUV comprising: a body extending along an axis X and having a head portion, a middle portion, and a tail portion, wherein the middle portion is sandwiched between the head portion and the tail portion along the X axis;a cross-section of the middle portion, substantially perpendicular on the X axis, having a triangular-like shape;the head portion including a base portion having the triangular-like shape and configured to match the middle portion;the head portion having a tip that, when projected along the X axis on the base portion to a projection point, the projection point lies on an altitude of the base portion having the triangular-like shape, between a centroid (GC) of the triangular-like shape and a corresponding side of the base portion; anda seismic payload located within the body and configured to record seismic signals. 14. The AUV of claim 13, wherein the triangular-like shape includes a triangle for which all vertices are replaced with curved lines. 15. The AUV of claim 13, wherein the tail portion has a base portion having the triangular-like shape and configured to match the middle portion. 16. The AUV of claim 13, further comprising: two engines and two corresponding propellers provided in a plane that does not include a tip of the tail portion. 17. The AUV of claim 16, wherein the plane also does not include the tip of the head portion. 18. The AUV of claim 13, wherein each of the head portion and the tail portion has holes and/slots for water intake and water discharge. 19. The AUV of claim 13, further comprising: an intake water element located on the body and configured to take in water when deployed underwater;at least one propulsion nozzle located at a tail portion and configured to eject the water from the intake water element for actuating the AUV;at least one propeller located in a channel connecting the intake water element to the at least one propulsion nozzle, the at least one propeller being configured to eject the water at the at least one propulsion nozzle. 20. The AUV of claim 13, wherein the head portion has three faces, two of the faces being symmetrically distributed about a transversal plane that cuts in two the body and includes the axis X.
