For many of the field projects on animal behavior conducted by Roger Hanlon there are supporting data on digital video.

Many of these sequences are highly unique (and biologically rich) due to the diving methods and behavioral sampling routines developed by Dr. Hanlon and his colleagues.

Contact Dr. Hanlon directly at concerning viewing, use or sale of this footage, most of which is shot on MiniDV (digital video).

High Del TV footage now available on some cephalopod species shot with Panasonic HVX100 (P2 stystem).
