cryptic coloration |
adopt a pattern to match the environment |
|
|
countershading |
dorsal is dark and ventral is light |
|
|
aposematic coloration |
reminds predator of previous bad experience, bright colors, usually poisonous |
|
|
mimicry |
uses aposematic coloration to mimic a poisonous creature |
|
|
community succession |
periodic change in the assemblage found in a community |
|
|
generalist community |
change in environment and require no specific resources |
|
|
intermediate community |
fewer generalists, more specialists, good competitors |
|
|
climax community |

|
|
appendage |
proximal (closer) and distal (further) |
|
|
germ layers |
ectoderm (outer), endoderm (inner), and mesderm (middle) mesoglea is the gooey stuff in between |

|
|
psuedocoelomate |
false space |
|
|
coelmate |
space between gut and body wall |
|
|
advantages to having a coelem |
