Image descriptions:
A transparent PNG of a leucistic male (identifiable by the presence of claspers between the pelvic fins) oceanic manta ray from the back. It is mostly pale with patches of darker coloration on its dorsal fin and on the leading edges of its pectoral fins.
A transparent PNG of a giant oceanic manta ray from the front; it is oriented vertically with its cephalic fins down in a feeding position and its mouth is closed. The parts of its underside that are visible are predominantly white, and it has a dark patch at the bases of its cephalic fins.
A transparent PNG of a giant oceanic manta ray from below; its cephalic fins are down in a feeding position. Its ventral side is about half white, with smoky coloration on the posterior half of its pectoral fins and abdomen, black freckles on its abdomen, dark smudges around its eyes, and a few large dark spots behind its gill slits.
A transparent PNG of a reef manta ray from a 3/4 view and below; its cephalic fins are loosely down. Its ventral side is almost entirely white, though it has a few grey freckles on its abdomen and one grey streak between its gill slits; and it has a few notches in its pectoral fins near its tail. There is a small fish swimming close to its underside.
