An aligning and lifting device is disclosed. The invention may be for use with an underwater cage including a top portion and a bottom portion. The aligning and lifting device includes a male member having a support surface fixed to the top portion of the cage, an integrally formed wedge shaped portion depending from the support surface for lateral alignment capabilities, and an alignment pin projecting from the distal end of the depending wedge shaped portion for facilitating vertical alignment. The device also has a female member that includes integrally formed side walls and complementary support surfaces opposed to the support surface of the male member, thereby defining a complementary wedge shaped opening for receiving the depending wedge portion of the male member. An alignment pin hole is formed at the base of said complementary wedge shaped opening for receiving the alignment pin of the depending wedge. The male member is aligned with the female member in a vertical direction by insertion of the alignment pin into the alignment pin hole and in a lateral direction by mating of the male wedge with the complementary shaped female opening.
