One of my first practical’s for
my module 'Diversity of Life 2' was to dissect crayfish. This module covers the
diversity of the invertebrates. Half of the module is arthropods and the other
half is on everything else...
In college I had dissected a fair
few of the basic things like pigs hearts, lungs, frogs, rats and even an
octopus but nothing to the skill in which I would need for my degree. It was
fairly straight forward, and it was very interesting. I learnt that putting it
underwater after the initial dissection enabled me to see things more clearly
for example its gills.
I also had to do a two detailed
scientific diagrams; one of the external dorsal view of the crayfish and
another of the ventral internal anatomy.
A very interesting start to my degree.
