Species
Covenant Elites as they appeared early in Halo's development.
To design the various species of the Covenant, Bungie's artists looked at live animals and films for inspiration;[7] as a result, the species within the Covenant bear simian, reptilian, avian, and ursine characteristics.[7]
[edit] Elites (Sangheili)
One of the strongest and toughest foes of the game, Elites (called Sangheili in the fictitious Covenant language) stand at nearly 8 ft 6 in (2.59 m) and feature recharging personal shields. The Elites initially had simple mouths, which developed into pairs of split mandibles substituting for the lower jaws. Bungie concept artist Shi Kai Wang noted that project lead Jason Jones had, at one point, been insistent on giving the Elites a tail.[8] While Wang thought it made the aliens look too animalistic, the idea was eventually dropped due to practical considerations, including where the tail would go when the Elites were driving vehicles.[9] "At one point, we considered just having the Elites tuck their tails forward, between their legs," Wang noted, "But [we] abandoned that... for obvious reasons."[9] According to Paul Russel, when Bungie was bought by Microsoft and Halo was turned into an Xbox launch title, Microsoft took issue with the design of the Elites, as they felt that the Elites had a resemblance to cats that might alienate Japanese consumers.[10]

Kind of saying I don't have anything done there...
That'll be freaky though, if I had a tail and had to tuck it once getting in a vehicle; how awkward will that be?
Edit: Like if you agree that not giving Elites a tail is a good thing.
