| Distinguishing Characteristics |
- Terminal setae on longest appendages are long, delicate, and sparsely spaced on terminal segments.
- Appendages are more tubular rather than flattened in shape.
|
| Additional Notes |
- From the anterior end of the nauplius body the three paired lateral appendages are called the first antennae, second antennae, and mandibles.
- There are 6 naupliar stages. The molt from the 6th naupliar stage to the first copepodite stage results in a juvenile form having the general body shape and appendage structure of the adults. These copepodites undergo 6 additional molts the last of which is the adult stage.
- Identification to species based on morphology can only be accurately determined using features of the adults.
