of the University of Cincinnati (Ohio, USA) shot this infra-red
video of a captive snake (Fordonia leucobalia) eating a crab (Episesarma
versicolor) that was very near the upper size limit of what it could
sallow. From start to finish this epic battle took nearly a half
an hour! The snake had a body (SVL) length of 59 cm and was 152
grams and the crab was 15.2 grams. This individual was captured
and observed in Singapore at the National University of Singapore.
This species of snake occurs on the intertidal mud flats and muddy

countries where crabs are an abundant resource. This snake uses
a unique behavior of pinning the crab with its chin, neck and body
before it bites the crab, whereas other snakes capture prey using
an open-mouth strike, during which the needle sharp teeth snag soft-bodied
