Correctly documenting the spread of invasive species is incredibly important for control and predicting future spread.

European green crabs (*Carcinus maenas*) were first found in Washington state in 1998. Since then, they have invaded into the larger Salish Sea region and have begun to expand into Canada and Alaska.

# Scientific Context

+
Correctly documenting the spread of invasive species is incredibly important for stratifying control efforts and predicting future spread.

European green crabs (*Carcinus maenas*) were first found in Washington state in 1998. Since then, they have invaded into the larger Salish Sea region and have begun to expand into Canada and Alaska.
|
| 13 |
|
| 14 |
+
This invasion is especially worrying due to green crabs impact on native mollusks, crustaceans, and grasses. In Washgington, Dungeness crab fisheries, shellfish aquaculture, and eel grass beds which are critical for juvenile salmon are all in jeporardy due to green crab invasion.

# Dataset Description
|
| 19 |
+
Data were gathered from iNaturalist "Research Grade" category.
|
| 20 |
+
|
| 21 |
+
Photos were sorted to only include pictures where the carapace was clearly visable (This is a WIP currently, the model includes false data but performs well still).
|
| 22 |
+
|
| 23 |
+
This meant the removal of pictures that included only the claw, were too blurry to determine distinctive morphology, or were in pieces/broken.
|

+
|
