So my entry will be this lobster with his offspring swimming all around him. I photographed him in the Netherlands while diving.
Depending on the time of the year you can find a lot of lobsters sitting around in their caves or at night even wandering around the reef.
I also made a small post with my other Crustacea pics that i considered for submission.
Wow, a lobster! Beautiful shot. I just checked the post too, wonderful photos, thank you so much.
