Classifying (support system-animals)

SUPPORT SYSTEM OF ANIMALS




How to identify & classify the animals' support system?

1.  Is this land or aquatic animal? 
     If land --------- go to question 2
     If aquatic ------go to question 3
2. Is it internal skeleton, hard covering  or soft-bodied?

3. If it is aquatic, it is supported by buoyancy of water.
    BUT , is it vertebrate or invertebrate?

    If it is vertebrate, then it is aquatic vertebrate animal with            endoskeleton, and supported by buoyancy of water.

     If it is invertebrate, 
     is it hard covering or soft-bodied?
    If it is hard covering then it is aquatic invertebrate animal with     exoskeleton, and supported by buoyancy of water.
   If it is soft-bodied then it is aquatic invertebrate animal with     hydrostatic skeleton, and supported by buoyancy of water

1.  Is this land or aquatic animal? it is land animal.
2. Is it internal skeleton, hard covering  or soft-bodied?
     Internal skeleton, so it is endoskeleton.

1.  Is this land or aquatic animal?  it is aquatic animal.
3. If it is aquatic, it is supported by buoyancy of water.
    BUT , is it vertebrate or invertebrate?
    YES,  it is vertebrate, then it is aquatic vertebrate animal with            endoskeleton, and supported by buoyancy of water.
