Vilix'pran's species

Vilix'pran's species is an unnamed species of sapient creatures which reproduce by budding. A member of this species, Ensign Vilix'pran, is a Starfleet officer who served in space station Deep Space 9 in the 2370s, suggesting that the species might be members of the United Federation of Planets.

Biology
In this species, it appears that males are the ones that give birth to offspring. Alternatively, it is possible that they might be asexual or hermaphrodite and/or Vilix'pran simply preferred to identify as male. They reproduce by budding, producing anything between two and twelve offspring each time. Their offspring are referred to as hatchlings and require a hatchling pond, indicating that at least at this stage in life they're amphibious or aquatic. The hatchlings also have wings, which are prone to getting tangled if they're not properly cared for. It's not known whether they remain winged and aquatic as adults.

History
In 2371, Vilix'pran was budding with twins and already had four children from a previous budding at the time. The crew organized a baby shower for him, with Chief O'Brien building him a new hatchling pond and Garak providing baby clothes. In 2373, it happened again. Based on Pran's previous buddings, Dr. Bashir claimed that he could expect anything from eight to eighteen hatchlings total. Jake Sisko has babysat Vilix'pran's children on several occasions, making sure that their wings didn't get tangled.
