Arothron stellatus
''Arothron stellatus'', also known as the stellate puffer, starry puffer, or starry toadfish is a demersal marine fish belonging to the family Tetraodontidae. It is found in shallow water in the Indo-Pacific region.
==Description==
''Arothron stellatus'' is a medium-sized fish which grows up to in length.〔http://eol.org/pages/204717/details#size〕 Its body is oval shaped, spherical and relatively elongated. The skin is not covered with scales but is prickly. The fish has no pelvic fin and no lateral line. The dorsal fin and the anal fin are small, symmetric, and located at the rear end of the body. The head is large with a short snout that has two pairs of nostrils, and the mouth is terminal with four strong teeth.〔Lieske & Myers,''Coral reef fishes'',Princeton University Press, 2009, ISBN 9780691089959〕
The background coloration goes from white to grey, and the body is harmoniously dotted with black spots. The ventral area is usually clearer. The size of the spots is inversely proportional to the size of the fish; thus, a young individual will have large spots and adults of maximal size will have small spots. The juveniles have a yellowish body background coloration with dark stripes. The young adults still have stripes on the ventral area that will turn to spots later, and also some recollection of yellow on the body.
