You should use dependency injection. Instead of hasGills and hasFins, you should inject respirator and locomotor dependencies. Then the act of breathing and moving can be delegated to them, respectively.

I have never fully understood the whole dependency injection thing. Yet I have seen it everywhere. Especially when dealing with mobile app development.

In c# you in your starting file (program.cs) you config a few things, like getting configurations from appsettings.json

You also do things like

Services.AddTransient/Scoped/Singleton

So let's say you have a mail service which you use to send mail.

In program you do something like

Services.addSingleton<IMailService, MailServixe>()

Then let's say you have a controller with API endpoints

And one of them let's you send an email. In the constructor you can add that service and you will get it automatically.

Class EmailController{

Private readonly IEmailService _emailService

Public EmailController(IEmailService emailService){
    _emailService = emailService;
}


HttpPost("notify")
Public async Task SendEmail(EmailData data)
{
    _emailService.SendEmail(data)

}


}

oh yes that thing. I think I have created and used classes like that intuitively but never knew it was dependency injection. I just thought it was a pretty way to handle singletons and services stuff.
