  North 
  America 
  is 
  the 
  rugged, 
  indented 
  character 
  of 
  the 
  former. 
  Such 
  

   a 
  coast 
  is 
  favorable 
  to 
  a 
  greater 
  variety 
  of 
  littoral 
  species 
  and 
  it 
  is 
  

   probable 
  that 
  there 
  may 
  actually 
  be 
  twice 
  as 
  many 
  littoral 
  species 
  in 
  

   this 
  region 
  as 
  are 
  now 
  recognized. 
  

  

  Because 
  there 
  is 
  no 
  adequate 
  channel 
  opening 
  into 
  the 
  Pacific 
  at 
  the 
  

   north 
  to 
  permit 
  the 
  exchange 
  of 
  M^ater 
  between 
  it 
  and 
  the 
  Pacific, 
  the 
  

   Japanese 
  Sea 
  is 
  virtually 
  a 
  closed 
  system, 
  based 
  on 
  the 
  diversion 
  of 
  the 
  

   warm 
  southern 
  current 
  south 
  of 
  Kyushu, 
  which 
  turns 
  upon 
  itself 
  in 
  the 
  

   northern 
  reaches 
  of 
  the 
  Japanese 
  Sea 
  and 
  flows 
  southward 
  along 
  the 
  

   Siberian 
  coast 
  as 
  a 
  cool 
  current. 
  Like 
  other 
  similarly 
  enclosed 
  seas, 
  

   the 
  Japanese 
  Sea 
  has 
  a 
  fauna 
  with 
  endemic 
  species 
  as 
  well 
  as 
  forms 
  

   which 
  have 
  migrated 
  through 
  the 
  channels 
  into 
  it.
