An Investigation into the height to length ratio of Limpets on exposed and sheltered shores.

Aim: To investigate height to length ratio of Limpets on the middle shore, comparing the difference between an exposed and sheltered shore.

Site: (Sheltered shore) Angle Point (SM 875033)

* Ballentine's Exposure Scale grade 7.

* Faces North-East.

(Exposed shore) West Angle Bay (SM 852032)

* BES: Grade 3

* Faces South, exposed to the Atlantic Ocean.

Hypothesis: There will be a statistically significant difference in the mean height to length ratio of Limpets between the sheltered and exposed shores.

Independent Variable: The fetch over which the prevailing wind can blow over, which creates a difference in wave action. In each case an exposed or sheltered shore are chosen.

The Ballantine's Scale was used to show the level of exposure of both shores. This scale allows there to be a method for deciding whether a shore is exposed or sheltered.

The scale ranges from 1 to 8. The higher the grade, the more sheltered the shore is.

Dependent Variable: The height to length ratio of common limpets
