Field Notes
Left Portland dock at 8:30 am on Charter boat "The Lucky Catch" on a sunny, warm August morning. Light wind, bright sun, clear sky headed towards Portland Headlight. Stopped twice, pulled a total of four traps. We took samples from first stop, second trap. Water depth at site was 53 feet with rocky gravel bottom. Had traditional green trap, found 8 lobsters total, 4 native sea weed, amphipods, isopods, and hydroid. No invasive species were found in this trap.
The research question was which would be more abundant, native or invasive species in the waters of Casco Bay. One team member thought we would find more invasive species and one member thought we would find more native species
Supporting Evidence
This photo shows the four antennae of the lobster, one long pair and one short pair. One of the long antennae is tucked behind the lobster resting behind the thumb. This is a characteristic of the Homarus americanus.
The photo shows the four pairs of walking legs of the lobster, another characteristic of the Homarus americanus.
This photo shows the two claws, one large crushing claw (on the right in the photo) and one smaller cutting and tearing claw (on the left in the photo).

looks very dapper you should eat it
pictures!
I just love your pictures... especially the last evidence image. You so cleverly disguised the face with a claw!
Looks like a beautiful day to go lobstering on Casco Bay!
Nice photos
Your photos do a great job of showing lobster characteristic! I'd like to see photos of the other species you observed in Casco bay.
