Diving is a different experience

Well yesterday I went on a fossil diving trip. I am new to this but I'm sure all the divers that are out there know every time you go diving its a new adventure with new experiences. The water is getting colder now that its almost December, but there are teeth to be found so I was going in. Once on the bottom I began to search around in the darkness with my hands and small light. About 10 minutes later I saw the biggest crab I'd ever seen with claws half as big as my hand right in front of me so I quickly moved away with the current. A few moments later I saw it setting on the bottom... a 2-7/8 inch long colorful serrated posterior meg. Minutes after I found it I had to surface because my alternate air source started to freeflow, but I was content with my find and can't wait to dive again !
