Hello, is my sandbox draft for adding to the oarfish article. A few words may be different on the actual article.

Distribution
They are found to have cosmopolitan tropical, subtropical, and warm temperate distributions.

Anatomy and morphology
In some Oarfishes found, end of tails may appear stump-like; this is likely the consequence of self-amputation that is thought as a defense mechanism against predators.

Behavior
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 ROVs, supporting the hypothesis that oarfish have few potential predators.

Life Cycle and Reproduction
Based on their reproductive morphology, Regalecus russellii 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.

Form January to February, 2019, researchers tested and recorded the first successful instance of artificial insemination and hatching of the oarfish (Regalecus russellii ) using gonads from two washed-up specimens. Compared to adults, the body structure of newly hatched oarfish larvae look more compressed. The often larvae swam using mainly their pectoral fin, facing downward, with their mouths constantly open. They did not eat, so they had died four days after they hatched
