Monopterus albus

A ditch in Nara, Japan
My first ever swamp eel caught on a piece of crawler meat. I found their burrows in a swamp-eel-rich area, and induced them to come out of their burrow by swinging the bait at its entrance. After I made one come out by his/her half of body, I let him/her bite the bait and set the hook. I did this because it is so hard to pull them out of their burrows.
