Reproductive system three Differences from American lobster and human

1 answer

1) Structure: The reproductive system of American lobsters is significantly different from that of humans in terms of structure. Lobsters have separate sexes, with males having a pair of gonads called testes and females having a pair of ovaries. On the other hand, humans possess internal reproductive organs such as testes in males and ovaries in females, but these organs are not visible on the outside.

2) Fertilization: American lobsters practice external fertilization, where the female releases her eggs into the water and the male simultaneously releases his sperm to fertilize the eggs outside the body. In contrast, humans practice internal fertilization, where the sperm is deposited into the female reproductive tract, allowing for fertilization to occur within the female's body.

3) Reproductive strategy: American lobsters have a different reproductive strategy compared to humans. Lobsters have a polygamous and promiscuous mating behavior, meaning that both males and females mate with multiple partners. The male lobster deposits a packet of sperm, known as a spermatophore, into the female's reproductive opening, and she uses it to fertilize her eggs. In contrast, humans generally have monogamous relationships and tend to form long-term pair bonds for reproduction.
