Life Cycle = hatch from egg and grow to adult scud |
| Size | 4 - 10 mm (San Juan scuds are very small) |
| Colors | Light Gray, Blue-Gray, Light Olive |
| Action | Swims erratically and often will roll over to swim on it side. It is typically straight bodied when at rest but will curve its body when captured. A dead drift is the best presentation. |
| Habitat | Lives almost exclusively in areas where there is concentrated aquatic vegetation. Scud are omnivorous and will feed on plants and animals but most eat decaying matter in the river. |
| Notes | The scud is a freshwater shrimp (Amphipod). It is actually a crustacean that is a distant relative of true shrimp. You won't find too many scuds in the sandy or silty areas of the river. Look for moss or algae beds. |
