Why do lobsters represent the transgender community?

I had not heard of this until I was asked to answer this question. This is the result of my Google search.
Why the lobster emoji has become an unlikely ally to the trans community
The TL;DR is
“Since Unicode have showed no signs of releasing a Transgender Pride Flag emoji anytime soon, the transgender community has adopted the lobster emoji as their surrogate representation.

You may be wondering: why a lobster? Lobsters can be gynandromorphs, meaning they have both female and male characteristics. “

According to the Portland Press Herald, the adoption of the lobster emoji as a trans symbol began after the group created an online petition last month asking Unicode to make a pink-and-blue flag, a universally acknowledged symbol in the transgender community, in emoji form. Until a pink-and-blue flag emoji is created, users are encouraged to use the lobster emoji, which was one of 157 emojis approved by Unicode this year. (Lobsters can display both male and female characteristics.)

In the petition, the group wrote about their reason for advocating for representation[1]
