Greese, H. 1990 June 28 (continued) at 2134 hr I saw a small adult Leptodeira septentrionalis in the Cantarana Swamp, >3m above water in a small Pentaclethra (?) on the north side of the boardwalk, soon after it goes out over the water. The snake was ≈ same size as one seen on the "Jarantula tree" (see June 20), a sightly not far from this one (same snake?). This snake was stretched along a downward sloping limb ≈ its own diameter, w/ head dropped down a few cm and poking into a mass of suspended moss – the snake seemed to be struggling, pulling and pushing its head through the moss, and since no jaw movement or prey item was seen I surmised that perhaps the animal was shedding. at 2140hr Dave Hardy showed me an adult Sibon longifrenis and a giant Leptodeira septentrionalis in a larger Pentaclethra tree south (SE?) of the boardwalk, ≈3 m above the swamp water surface. The S. longifrenis was crawling slowly on a branch ≈ its own diameter, w/ >6 lateral bends of its body, and I was impressed w/ the easy visibility (by flashlight from several meters distance) of its distinct ventrolateral red spots – although overall the snake was not easy to see. The very large L. septentrionalis was crawling slowly along a limb, tongue flicking. at 2150 hr Dave showed me another adult L. septentrionalis in a tall swag in the NE portion of the swamp, 7-8 meters above the water – I think
