of macrofauna on high-energy sand beaches. --Continued 



Material and equipment Use 



Scientific supplies 



Chemicals 



Formalin (commercial solution of formal- 

 dehyde) 



Temporary storage of animals 

 (mix with seawater) 



Magnesium chloride (M^Cln) or 

 Epsom salts (M^SO^ . 7H 2 0) 



Relax organisms for 

 identification 



Rose bengal (biological stain) 



Ease in sorting samples 



Marble chips or borax or equivalent 

 buffer 



Buffering seawater and formalin 

 solution 



Glycerin 



Keep materials from becoming 

 brittle ' 



Alcohol (denatured ethyl or isopropyl); 

 drugstore rubbing alcohol may be used 

 without dilution 



Permanent storage of samples

Sample separation of organisms 

 from sediment 



Erlenmeyer flasks (4 liters) 



Sample separation of organisms 

 from sediment

 enamel pans 



Sorting animals 



Sample jars and caps 



Storage of animals 



Museum labels or high-grade rag-bond 

 paper (not gummed) 



Labeling 



Pen and India ink
