Despite some support from the spectators, detractors were quick to take to the internet, questioning how his speed, or lack thereof, and less-than sculpted body landed him a spot at the games.
Technically the Olympic debutant didn't even qualify for the 100m free-style, but was in fact a special invitation from the international swimming body to athletes of under-represented countries.
Rumour has it he wasn't even his country's best swimmer - but was in the pool more as a result of special favours - his father is thought to be the president of Ethiopia's Swimming Federation.
There's only one other Ethiopian entering the Olympic pool at this year's games: Rahel Gebresilassie in the women's 50m freestyle.
Despite some criticism, Habte was reportedly happy with his performance.
"For Olympics, my first one, I am so happy. For all the sportsmen, the Olympics are big. So to be [in] competition in the Olympics, I am so happy."
