THE ANIMAL LIFE OF THE GROUP. 355 



Both known species of d()l])hins occur in llawnii. As they are very large 

 fish of the oi)en sea and are surface swimmers, they ai'c occasionally seen by 

 passengers on board sailing' vessels. While the name dolphin i-iglitl\- belongs 

 to a group of small whales, it has been associated with this fish. In song and 

 story their beauty of color and grace of motion have received much attention. 



Eels. 



The order Apodes, which includes the eels and raorays is well represented 

 in Hawaii, several dozen species frequenting the coral reefs and rocky coasts. 

 Eel-fishing is a favorite sport, as the animals are easily enticed from their 

 hiding places in the rocks, when they may be hooked or speared. 



The Hawaiian name puhi is applied to the class as a whole. Puhi-uha 

 signifies slippery eel, and is applied to the conger-eel. Some of the larger 

 examples attain a length of five or six feet, and are much sought after as food. 



Frog-Fish and Flying-Fish. 



Two genera of f rog- fishes ^^ occur, but representatives of only one genus 

 have so far been taken in the shallow water or open sea. They all have the 

 head compressed, and the skin covered with prickles, the body oblong and 

 much compressed. They are fantastic -looking fishes, often gaily colored, and 

 feed among the seaweeds on the reef, wheie they creep about like toads. They 

 are also capable of filling their capacious stomachs with air, which enables 

 them to float on the surface of the water. Eight species occur on the reefs, all 

 of which are provided with one or two whip-like lashes that protrude from 

 the upper lip to form a "bait" over their cavernous mouths. 



Flying-hsh "' abouml in the open sea in all tropical waters, and Hawaii's 

 waters are in no way an exception. Five well-marked genera include the 

 eight species, all of which are called malolo by the natives. They are most 

 abundant during the summer months. A common species ^"^ has the upper part 

 of the body dark blue and the fins about two-thirds the length of the Ixidy. 

 They, in common with their cousiiis, usually occur in shoals, and are a source 

 of interest to the voyager as they leap from the surface of the sea and sail 

 away, sometimes sustaining a so-called flight for a hundred yards or more. 

 The most recent sport in Hawaii is flying-fish shooting. This is done from a 

 power launch, as the fish skim over the water. The fish are a favoi-it(> food of 

 the natives, who prefer to eat them raw at their feasts (aha-aina). 



Gobies. 



Gobies ''" have no near relatives among the spiny-rayed fishes, and as a 

 family may be easily recognized. The ventral fins are inserted very close 

 together; there is no lateral line and no bony stay to the preopercle. which 

 gives to the gills a peculiai- flabby ap|ieai'ance. The species are very nunierous 

 in the tropics, there being fourteen genei'a in Hawaii, usually with Init oiu' or
