Vilix'pran

From Memory Alpha, the free Star Trek reference.

Vilix'pran was a Starfleet crew member assigned to Deep Space 9 in the 2370s.

In 2371, he was assigned to cargo inventory, but Julian Bashir made a request for the ensign's transfer because he was budding with twins. Bashir and Miles O'Brien were throwing him a baby shower; O'Brien was also building him a hatchling pond, while Bashir had ordered baby clothes from Elim Garak. A prior budding had produced four offspring. (DS9: "Heart of Stone")

Jake Sisko babysat his hatchlings on several occasions, a task which involved preventing their wings from getting tangled. (DS9: "Business as Usual")

By 2373, Vilix'pran had been promoted to lieutenant, and was in the process of budding for a third time. The nature of his species' reproductive system meant he could be expecting anything from eight to eighteen hatchlings, and he requested larger quarters from Major Kira. (DS9: "Apocalypse Rising")

Vilix'pran's species was not revealed on the series. It seems that his species shorten their names when used in general conversation, as he was sometimes just called just Pran. In "Business as Usual", Jake referred to Vilix'pran as Ensign Pran. Presumably, this was just a slip of the tongue, and Vilix'pran was still a Lieutenant.
