Tiger sharks mature at an intermediate 8-10 years of age. This is the most primitive mode of reproduction. Females have large eggs with yolk to nourish the young through development. There is no parental care invested in development of the young. An egg case made of protein fibers covers the developing embryo and is released to the environment.
Development continues in the egg case for several months to a year.
This the most common mode of shark reproduction. Embryos in the female s uterus are nourished by yolk stored in a yolk sac. There is no placental connection to the mother. Young are born after development is completed. Among the interesting variations in ovoviviparity is fetal cannibalism.
