The larvae often swam using mainly their pectoral fins, facing downward, with their mouths constantly open. The larvae were invertebrates but had bones in their head area, as well as fins. They died of starvation four days after they hatched. 505:(463–492 m or 1,519–1,614 ft). In the 2011 sighting, an oarfish has been observed to switch from swimming with a vertical posture to swimming laterally, using lateral undulations of its entire body. Oarfish were found to have late or slow flight responses towards approaching remotely operated vehicles, supporting the hypothesis that oarfish have few natural predators. 642:, up to six millimetres (0.24 in) across, which are incorporated into the zooplankton. Based on their reproductive morphology, oarfish are thought to batch spawn. Within each breeding season that may last one or two months, individuals spawn once or multiple times in discrete spawning events before their gonads enter a long, regressive stage of reproductive development. 166: 264:
The dorsal fin originates from above the (relatively large) eyes and runs the entire length of the fish.

Like the topic of behavior and hunting, scientists know very little about the actual breeding habits of these fish. A single female can produce hundreds of thousands, to millions of eggs. It lays its eggs in the water column and they float freely in the water.

Oarfish coloration is also variable; the flanks are commonly covered with irregular bluish to blackish streaks, black dots, and squiggles. These markings quickly fade following death. It is probable that these markings are bioluminescent in the deep sea.

These studies have shown that female oarfish have bifurcated ovaries containing a cavity through which the eggs pass before leaving the body of the oarfish. 378:, the phylogenetic placement of the Giant Oarfish was further verified.
