Collection of images that features the aquatic species (though not necessarily underwater/inside the ocean) mainly focused on the seapony designs that appeared in the 4th gen (and others that present a similar shape). The hippocampus design can contain variations in their bodies and there might be material that falls under the gray area (hybrid bodies or overlaps with merponies). Therefore, there aren´t strict lines on what counts as "gen 4/2017's movie style" seaponies or not, except for the two limbs/hooves and the big tail. The 4th gen label works as a point of reference.
