Invasive Crab Species

In total 23 Asian crabs were collected, both female and male.
Evidence to prove this is that the Asian shore crab has 3 spines, striped legs, and a dark shell. They are also much smaller in comparison to the green crab.

Invasive Crab Species Search and Identification- Rock Crab

Using a bucket, net, and bare hands, the group searched the intertidal and spray zones to find the Rock Crab invasive species. Many of the crabs were found under rocks and wooden planks. They were then catalogued based on visual characteristics to identify them to the correct species. The group also took pictures for more evidence of the species. The Vital Signs field sheet was also used to identify the Rock Crab. The coloration of the Rock Crab made it much easier to identify in a group of Green and Asian Shore Crabs. Out of 48 crabs, only 1 male Rock Crab was found.

They were then catalogued based on visual characteristics to identify them to the correct species. The group also took pictures for more evidence of the species. The Vital Signs field guide was also used to properly identify the species. The distinct stripes made the Asian Shore Crab very easy to identify. Out of 48 crabs, 43 Asian Shore Crabs were found. Of those 43, 25 were male and 18 were female.

They were then catalogued based on visual characteristics to identify them to the correct species. The group also took pictures for more evidence of the species. The Vital Signs identification sheet was also used to properly find the correct crap species. The 5 ridges on the front side of the shell made the Green Crab easier to identify. Out of 48 crabs, only 4 Green Crabs were found.
