 or young. 



Development 



There are published descriptions of the eggs of Aulorhynchus 

 (Limbaugh, 1962; Ida, 1976), Hypoptychiis(\s\\i%aku 1957; Ida, 

 1976), gasterosteids (notably Kuntz and Radclifle, 1917; Vrat, 

 1949; Swamp, 1958), Solenoslomus (Padmanabhan, 1961), 

 Macrorhamphosus (Sparta, 1936), and Fistulana (Delsman, 

 1921; Mito, 1961a; Watson and Leis, 1974). There are few 

 descriptions of the eggs of syngnathids due to the unique male 



brooding habits of this group, however, Hudson and Hardy 

 (1975) provided a good description of Hippocampus erectus 

 eggs. Most accounts simply include the number and size of eggs 

 in the male's pouch (e.g., Fritzsche, 1980). Gudger (1905) pro- 

 vided a fairly extensive treatment of the embryology of Syng- 

 nathus floridae. 



Larvae (usually just one or two and not a series) have been
