Summary:
A small slender green to brownish clingfish covered in tiny close-packed brown spots, many forming short dark lines and blotches on the head and body, with six short dark brown bars across back and row of dark brown blotches along the midside. Larger individuals often have small white blotches, sometimes producing a piebald appearance. 
The Spadenose Clingfish has a relatively long, depressed, rectangular-shaped snout (when seen from above), and the anterior and posterior nostrils positioned well before the eye.
