When I was at Trans Pride in Brighton I was rather confused by some people in the parade apparently dressed as lobsters, and carrying plastic lobsters, and flags with lobsters on them. I mean, I’m very fond of lobsters, but why at Trans Pride?

Being a good investgative jouralist, I looked for them in Brunswick Gardens and, having found their stall, asked them what this was all about. It turns out that it is all the fault of Google, Apple and Facebook. Bear with me.

Of course most things bad in the world are the fault of Facebook these days, but lobsters are not bad, and why Apple and Google as well? Well, because they are all voting members of an IT industry body called Unicode which is responsible, among other things, for regulating emojis.

You may have noticed that there are a lot of flags missing from the set of emojis available on your phone or tablet. There is no Welsh flag, for example. Almost as importantly for me, there is no trans flag. That would be very useful. Apparently it is one of the most commonly requested new emojis. But Unicode says there is no need for one.

And yet, when a small group of people petitioned Unicode for a lobster emoji, apparently on the grounds that having to use a shrimp or a crab would be confusing, this was quickly granted.

As a result, the lobster has become a symbol for the campaign for a trans flag emoji. And this, as the petition points out, is rather apt, because lobsters are one of the select group of creatures that can become gynandromorphs. That is, you can find lobsters that are male on one side of their body and female on the other side. Biology is way more complicated than the average anti-trans activist would like to admit.

So if you see me using a lobster emoji on Twitter in future, you will know what it means.
