While this crab wasnt too special, it was the first I found with my brother, so I have been using it as an "experience" crab... then I found the flabellum and thought it was cool so have left it there...
Now I have a little bit better prepping gear and more patience I investigated something else I saw on the top... Of course I have a suspicion but have been wrong just about every time...
Its about 3-4mm long.
Can anyone give me any idea what it may be? Apologies for photos, they were taken with my cell as I cant find my macros for my dslr.
