Fic. 120. Daphne 

 A photo-micrograph of the little crustacean of supreme importance as food for 

 young fishes, especially the goldfish. They are taken greedily by practically all the 

 smaller freshwater fishes. Being only the size of a pin-head, it takes a few mil- 

 lions of them to satisfy the appetite of several large goldfishes. 



The ovals in the hody are eggs, which are carried until hatched. Fishes too 

 small to eat an adult daphne follow it around waiting for it to drop the young. 

 The branched arms are for swimming and gathering food, which is vegetable in 

 character. 



The inset shows a characteristic life-size group of daphnia, presented mainly in 

 the interest of numerous readers who would like to collect the "bugs," but who are 

 unable to identify them from Fig. 122 and <iui limited word description.
