Sharks are some of the most fascinating creatures in the ocean, and new research is giving us a glimpse into their evolutionary history. Scientists recently uncovered evidence of a shark nursery in the open ocean, a finding that provides insight into the evolution of birth in cartilaginous fish.

The researchers studied the reproductive behavior of a species of carpet shark and discovered a unique nursery area near the surface of the open ocean. This nursery area is populated by pregnant females, newly-born pups, and juvenile sharks. The discovery of this nursery highlights the importance of shallow-water habitats for the reproductive success of cartilaginous fish.

The presence of a nursery in the open ocean also has implications for the evolution of birth in cartilaginous fish. In most species, the female gives birth to live young. However, in some species, the eggs are retained within the mother until they hatch. By studying the reproductive behavior of the carpet shark, scientists have gained insight into the evolutionary history of cartilaginous fish.
