"Our biologists know a fish when they see one" - Aquarium Poster
Scientists/Marine Biologists are enemies in Octodad: Dadliest Catch. They are employees of the Aquarium and if Octodad is spotted by them, it quickly causes a game over. At one point, Octodad has to sneak past them. He can wear a female scientist disguise, yet there are no human female scientists.
It is also very possible they are a refrance to the scientist from Half-life 1998 as there voices sound very simular to the scientist in that game, along with there appearances being simular.
