About the Amoeba Sisters YouTube Channel:
The Amoeba Sisters is a YouTube channel started by sisters Sarina Peterson and Brianna Rapini in July 2013, and it specializes in teaching biology concepts at the high school level (and beyond) by using illustrated cartoons. Brianna Rapini is a former high school biology teacher and worked in three different Texas public school districts for a total of 12 years. Sarina Peterson is a former program analyst in a large Texas public school district, and she is a self-taught cartoonist who learned to draw on YouTube. The channel was originally created as a way to make memorable and short biology videos that could be used in lieu of lengthy lectures so that more time could be available for class discussion, labs, and student creation. The channel grew unexpectedly and in the Fall 2017, it became necessary to work on the channel full-time. Run by only the sister team of two, the channel has grown to over 1 million subscribers with a cumulative view count of over 110 million (as of March 2021) - you can see the channel's current stats as of today's date here. Their online community has translated videos in over 22 different languages. The two sisters formed Amoeba Sisters LLC and created some optional resources, such as their "Unlectured Series," that complement their videos and also help with supporting them financially so that they (1) can create full-time and (2) keep their YouTube videos, comics, and GIFs free.

​YouTube Channel Mission Statement:
To demystify science with humor and relevance via our creations (videos, GIFs, comics, resources).

YouTube Channel Audience:
The Amoeba Sisters YouTube Channel is directed for high school biology (as Pinky is a former high school biology teacher); in addition, a public survey of over 26,000 viewers on their YouTube community tab in November 2019 also showed 37% of the responding audience as college/university students as many of these concepts (protein synthesis, mitosis, DNA replication, etc) are taught in introductory biology at the college level. The channel is for anyone wanting to learn biology.

Interesting Facts About The Amoeba Sisters YouTube Channel:

• Amoeba Sisters gets its name from the fact that the creators are actually sisters and that the organism amoeba, with its amorphous shape, was one of the easier organism types to draw as their characters. However, as pointed out on the about page, these are two very unique amoebas. Amoebas don't have eyes, stars on their heads, or heads...
• The main Amoeba Sisters characters - "Pinky" and "Petunia" - have had some gradual changes in their appearance over the years. Some of the changes include the stars on their heads. They stars have not only changed positions, but sometimes they sink into the cytoplasm, so only a few points are visible. You can see how the characters have changed on the milestones page.
• The personalities of the main Amoeba Sisters characters "Pinky" (Brianna) and "Petunia" (Sarina) are inspired by the sisters' own personality traits. 
• The sisters live over 200 miles from each other: one in the Houston, TX area and the other in the Dallas, TX area. They work with each other remotely.
• Script and audio are done by "Pinky" (Brianna) and all art and video editing is done by "Petunia" (Sarina). While there are occasional videos where Petunia will talk such as the beginning of their microscopes video, most voicing is done by Pinky and all drawings are done by Petunia.
• "Petunia" (Sarina) has no training in art, and she learned to draw mainly from YouTube. Since the channel generally doesn't delete old videos, you can see the progression of her art from the very beginning on their milestone page.
• Video topics tend to be based on a high school biology concept or standard, and they're often suggested by the community. A topic is selected each month, sometimes by a vote.
• The channel has a YouTube biology learning playlist  ("learning playlist" feature was announced at VidCon in 2019) with over 75 videos.
