I ran into a lady 2 1/2 years ago who was looking for a home for her grey bamboo shark. She said the shark was around a year old. It was around 10-12 inches. So i took it. She grew to 22 inches and August of this year she layed 4 eggs. I didnt think anything of it because there is no male shark. After she layed the eggs she would not eat anymore and lasted for about month before she died. I just kept the tank going to keep the live rock alive. I was walking by last night and saw something swimming and looked and it was a baby shark about 4-5 inches long. My question is how could this have happened without a male? Thought i knew everything about the birds and the bees lol.
