ANATOMY OF THE DOGFISH SHARK
External Morphology
Date: August 28, 2014 Rating: INTRODUCTION
Can you imagine how and what it could be like when an organism does not have a specified structure and surface? Plants have cell walls; even amoebae have plasma membranes that wall off the protoplasm from the water surrounding it.
In humans, perhaps, no other organ receives so much attention both from its owner and the eyes of the others. The skin is always the first line of defense against the dangers of the outside world. Though not always clearly, evidences of some internal disorders, external affronts—bumps, cuts, chafe, insect bites, and other reactions. The external morphology identifies what one is.
The integument serves as a factor for survival. The integument system of the aquatic and terrestrial organisms conforms to a basic morphologic pattern, with a multi-layered epidermis derived from ectoderm and a dermis from a mesoderm.
The protective roe of the integument is primary to protect the internal organs from injuries and from other substances, the rays of the sun, fur of a threatened mammal, danger alert. On the other hand, the skin is also for respiration, excretion of carbon dioxide, thermoregulation, locomotion, homeostasis maintenance, for nourishment and skin coloration signals.
The integument system of dog fish shark, Squalus acanthias, is portion of what makes up its external morphology. In this experiment, integument comes along with the external features of the shark—its gills, scales and appendages in the form of fins. Shark, a typical vertebrate means that its head is incased in a cranium and its vertebrae are associated with the notochord. More of its external morphology will be discussed here.
SPECIFIC OBJECTIVES
By the end of the experiment, the students should be able to:
1. To be able to have a fuller understanding of the structure of the skin of the shark.
2. To be able to identify the different parts of the shark and its
