Starting of Lab
They have been given a vacuum sealed preserved Squalus Acanthias. They cut open the top of the bag and drained the fluid into the sink. Then they cut open the top of the bag and drained the fluid into the sink. Then they grabbed the tools they needed to dissect the Squalus Acanthias. Tools that were used are forceps, metzenbaum scissors, scalpels, and teaser needles (angled and straight). They put the Squalus Acanthias into a pan. They measured it and it was 31 centimeters.
Skin Graft They took a scalpel and forceps to cut a piece of its skin off about 7.62 centimeters. This process is called a skin graph. We took a skin graph underneath the caudal fin and above the second dorsal fin. Then they felt the difference of the skins, the one on the outside and the skin that was cut. Most people use the skin of the shark for burn victims, which lost 80% to 90% of their skin. First Cut …show more content…
Opening the Squalus Acanthias, and cutting any of the extra skin off it, so that it could be a clear opening.
Locating Organs & Reproduction
They locate the epididymis, stomach, spiral valve intestine, epigonal organ, rectal gland, pylorus, liver, spleen, kidney, pancreas, oviduct, colon, dorsal aorta, uterus and ovary. They also saw in the oviduct that there was 5 membranous sac or they are also called the yolk sac. Shark’s eggs are fertilized inside the female’s body. The male shark has claspers extensions of the pelvic fins that are used to transfer sperm to the female and fertilize her eggs. (Shark Reproduction, 2016). This is a viviparity birth which is when sharks carries embryos through the entire gestation period and give birth to live pups.
