Paoo Kaulaloa 



11 6-1 4 Gobiichthys papuensis (Valenciennes) 



From Jordan & Evermann 



This goby is an olive gray color in life and is marked on the trunk 

 and tail by from six to eleven darker bands. It reaches a length of nearly 

 six inches. 



It inhabits both fresh and brackish water. In the Hawaiian Islands, 

 it is known from Oahu and Hawaii but undoubtedly occurs on all of the 

 Islands. 



This goby is distributed throughout the East Indies, Micronesia, and 

 Polynesia as far as the Hawaiian Islands. 



THE REMORA FAMILY 



Also known as the Shark Pilots, Shark Suckers, and Sucking Fishes 

 117 Family Echeneidae (Echeneididae) 

 The remoras are a very unusual group of fishes because they possess 

 a sucking disc on the top of their head by which they attach themselves 

 to larger fishes. This sucking disc is composed of what remains of the 

 first dorsal fin. Over millions of years the dorsal fin has slowly changed 

 until today it remains as a sucking disc placed on the top of the head 

 and neck. It is composed of a series of double, transverse, movable, 

 cartilaginous plates which are serrated on their posterior or free edge and 

 which have been shifted forward on the body until they lie over the 

 head. By means of this disc these fishes attach themselves to other fishes 

 or to floating objects and are carried for long distances in the sea without 

 effort. They attach themselves to sharks, barracudas, swordfishes, turtles, 

 and other free-swimming fishes. They usually drop off their host when 

 it is pulled from the water.
