Endocrine System of the Sea Urchin
The sea urchin is dioecious, which means that it has two sexes. However, it is very hard to tell the difference between them. One way you can do this is by noting that the male sea urchin is generally in elevated, exposed regions of the ocean to spread its milt, or seminal fluid, throughout the ocean currents. The milt is produced by the seminal vesicle, which is a very important gland of the endocrine system in sea urchins because it allows the urchin's spreading of semen, which results in reproduction.
Female sea urchins are found in tight crevices in rocks mainly because it serves as protection for growing larvae. The females receive the milt and store it in the seminal receptacle, which is where fertilization occurs. The entrance and exit into the seminal vesicle and receptacle in female and male sea urchins is called the gonad. The gonad serves as the sexual organ and it is important in the reproduction process because it allows substances produced by the Endocrine System into and out of the sea urchin.
