I am very much pleased for publication of the monograph on spadenose shark Scoliodon Laticaudus. It has fulfilled my long standing dream to contribute something to the field of Zoology, as a token of gratitude which I owe to my profession. I hope it will prove of assistance to students, teachers and also to researchers in the field of fisheries. The study was undertaken because of almost absence of additional and/or recent information on an Indian shark since pioneer work by Thillayampalam (1929). It took about eight years of hard but certainly enjoyable work during last decade of my career as a teacher of Zoology.
