Lobsters are part of the class I was assigned. They are part of the Crustacean class. Hopefully the information you read here will be very insightful and help you see just a little bit inside the world of lobsters. I never realized that lobsters were in the Phylum of Arthropoda. When I think of the word or association of Arthropoda I think of clams and things like that, but lobsters are part of it too.
Lobsters are sea animals, meaning they live in the sea.
The exact numbers of how many there are would be immpossible to find because of how many there are. Lobsters also live on the sea floor making them very difficlut for us as humans to gain easy access to. It is estimated that the arthropoda population of the world numbers about a billion billion individuals. The first fossils and the beginnings of Lobsters and all anthropodas date to sometime around 550 million years ago. This period of time is called the Cambrian period.
