Specify which. Salarians have cloaca, as evidenced by Mordin Solus once reminiscing about a colleague, calling him a cloaca. Also, I imagine some of them to have ovipositors instead. Asari probably don't have vagina, given their ability to "meld." Sounds like something that requires a bit of "protruding."
Sounds like someone is an anthropocentric shitlord to me. Shame.
