Asperoteuthis mangoldae: Beaks in 2D

Richard E. Young
Photographs of the beaks seen in 3D, using anaglyph techniques, can be found on another page. To get the 3D effect, you must use glasses with red and cyan lenses (filters) over your regular glasses. The beak photographs were made using Anachrome Aviator glasses (see: http://www.anachrome.com/glassbuy.htm) which cost $9.00.
