Bluefin Tuna Comparison Research Paper

The most significant difference between the reproduction of humans and the bluefin tuna is that humans reproduce internally and tunas reproduce externally. In humans, their reproduction consists of sexual intercourse where the male sex organ is inserted into the female sex organ. During this process sperm from the male swim and fertilise the egg within the females. In the Bluefin tuna, both genders of fish release a substantial amount of sex cells into the ocean in order to produce the eggs. In addition, the Bluefin tuna lays eggs and humans give birth to live young. Another comparison is the variation in the feeding processes of the embryos. Within the fish eggs there is yolk, the yolk is the food supply for the tunas up until a few days
after they hatch. However, in humans the placenta is developed within the mothers, connected to the placenta is the umbilical cord. The umbilical cord is where the embryos receive their necessary food and oxygen from their mothers intake.
