Table 3. Environmental variables and eel behavior observed just prior to and at the moment of predation.

# X-tag	Day of predation	Moment/Period of predation	Fraction of the moon's visible disc (from new moon 0.00 to full moon 1.00)	Depth of predation	Duration of eel activity between release and predation (days)	Eel behaviour just before predation
110 612	14-Oct-11	Night- 3 hours before sunrise	0.97	<20 m	2	Eel in surface waters during the entire track
110 614	13-Oct-11	Night - 2 hours after sunset	0.99	≈−22 m	1	Eel in surface waters during the entire track
110 615	8-Oct-11	Day – 1 h20 before sunset	0.85	≈−15 m	4.5	Inversed DVM (in surface waters during the day)
110 616	25-Nov-11	Day- 4 hours after sunrise	0.00	Between −50 m and −26 m	52	Decreasing DVM at depth prior to predation
110 617	1-Nov-11	Day- 2 hours after sunrise	0.33	≈−20 m	21	Inversed DVM 24 hours prior to predation
110 618	13-Oct-11	Day - 2 hours after sunrise	0.99	≈−20 m	1.5	In surface waters prior to predation
