GENERAL BIOLOGY 



4. Light. Is it a form which seeks or avoids strong light, and 

 what adaptations does it show in this connection? 



III. MOVEMENT. 



1. Is the animal free-moving or sedentary? (a) If free moving 

 is it passively carried by winds or currents, or does it move active- 

 ly ? Do the organs of locomotion indicate that it is fitted for swim- 

 ming, walking, running, creeping, leaping, burrowing, or flying? 

 Draw one or more of the locomotor organs, (b) If sedentary is 

 it free or attached? Show by drawings the means of attachment. 

 Are there any rudiments of locomotor organs? Are sedentary 

 animals descended from free-moving ones, or vice versa? 



2. Does this species undergo migrations? If so describe them. 

 In the specimen assigned you by what means is the dispersal 



of the species assured, and what are the barriers to such dispersal? 



IV. GEOGRAPHICAL DISTRIBUTION. 



i. To what Zoogeographical Region of the earth is the animal 

 native ? 



B. RELATIONS TO ORGANIC ENVIRONMENT. 



I. FOOD. 



Animals are monophagous or polyphagous, depending upon 

 whether they live upon a single kind of food or on several kinds ; 

 they are carnivorous, herbivorous, or omnivorous depending upon 

 whether they eat flesh, plants, or both. 



1. Correlation of Food and Structures. Determine by means of 

 the organs of prehension, the teeth, or the character of the mouth- 

 parts of the specimen assigned you what is the nature of its food. 

 Draw these characteristic structures. 



2. Correlation of Food and Habits. Point out, if possible, the 

 correlation between the food and the habits of the animal you are 

 studying. 



3. Storage of Food. Is this animal able to store up food in any 

 form? If so describe the process. 



II. MEANS OF DEFENSE AND OFFENSE. 



1. Active. Is the animal you are studying able to defend itself- 

 actively or not? If so, draw and describe some of the organs used 

 for this purpose. 



2. Passive. If it defends itself passively describe the methods 

 and structures by which this is done.
