I believe these kinds of books are introductory for further investigation and I hope I could have illuminated some part the faunal biodiversity of Persian Gulf and see of Oman.

Hassan Mohammadian Preface

This book is an introduction to two important groups of primitive in Persian Gulf and Oman Sea:

1 Urochordata 2 Cephalochordata

We have reports of about 40 species of Urochordates of Tunics and 3 species of or amphioxus in this book. The author has included the main text of pelagic of North West Indian Ocean by R.B. Seymour Swelle because of its historic and scientific importance. Dr. Swelle was the head of a scientific expedition group to Indian Ocean in 1933. His trip started with the financial support of Sir John Murray (The great oceanographer) and used the ship Mabahiss with the help of some Egyptian Scientist. He examined 209 stations and returned after nine months. The results of this important expedition were published by The British Natural History Museum . Other references used by author to complete this book have been cited in the reference section.
