Its hard to say if its a female body without having a male to compare
Females are usually longer and can exceed 70cm while males stay smaller than that.
From the relatively small fin, i gather its a male when comparing to photos of females.
Anyway, this european eel was still wet. As was the river rhine bank where i saw it washed a shore from a freak-bow-wave caused by a passing container ship.
Saw it from some 50 meters away. When i got there, the scene had mostly dried up from the glaring sun and 34°C.
I mean to have seen it twitch while approaching.
But no sign of life anymore when i took my wifes Xperia X for the shot.
Forgot my prawn eggs in the car sadly.
I am most proud about the legal use of portrait orientation
