Matching Properties for Type (a) and Class (b) of River Crayfish

To correctly match the corresponding properties for the type (a) and class (b) to which the river crayfish belongs, we can use the provided pairs of properties and match them with the type and class. Let's go through each pair and determine the correct matches.

1. Two pairs of antennae (two pairs of antennae): This property matches with the river crayfish, which belongs to class (b) - 2,5 and type (a) - 2,3. - The river crayfish has two pairs of antennae, which is a characteristic feature of this type of organism [[1]].

2. Five pairs of walking legs (five pairs of walking legs): This property matches with the river crayfish, which belongs to class (b) - 1,5 and type (a) - 1,4. - The river crayfish has five pairs of walking legs, which is a distinguishing feature of this type of organism [[2]].

3. Bilateral symmetry (bilateral symmetry): This property matches with the river crayfish, which belongs to class (b) - 3,5 and type (a) - 2,5. - The river crayfish exhibits bilateral symmetry, which is a characteristic of this type of organism [[3]].

4. Gills (gills): This property matches with the river crayfish, which belongs to class (b) - 2,5 and type (a) - 2,3. - The river crayfish has gills, which is a significant feature of this type of organism [[4]].

5. Ventral nervous system (ventral nervous system): This property matches with the river crayfish, which belongs to class (b) - 2,5 and type (a) - 2,3. - The river crayfish possesses a ventral nervous system, which is a defining characteristic of this type of organism [[5]].

Based on the provided pairs of properties and the corresponding type and class, the correct matches for the river crayfish are as follows: - Type (a): 2,3 - Class (b): 2,5

These matches align with the known characteristics of the river crayfish, confirming the accuracy of the matching.
