⦁ Squid: Squid have some unique adaptations. Some can change color, some use bioluminescence to create light, and some shoot ink to cloud the water and lose predators, they also have many other adaptions like the shape body, there long and skinny making them fast
Preparation for the Dissection The Dogfish shark is about 70 inches long and you should notice along the side of the shark there is a light colored horizontal stripe called the lateral line. Made up of a tiny pore that lead to receptors that are very sensitive to the mechanical displacement of water and sudden changes of pressure. You will need tools for this including Latex gloves, yard stick (with centimeters), scalper knife, scissors, probe, and if you have a weak stomach you should wear facemask so the smell won’t be bad. External Anatomy Let’s start with the pectoral fins which are toward the front and side of the Dogfish Shark. The Dogfish has two dorsal fins, you have a anterior or first dorsal fin and a posterior or a second dorsal fin both have spines so look they looked closely and are available to locate them.
Most of the members are gray in color and have some greenish tint with white bellies. This color balance enables the sharks to perfectly blend with the ocean since a prey viewing from the bottom will not see it sneaking in for a meal. The cephalofoil laterally project outwards thus giving the shark the hammerhead shape and, as a sensory organ, ability to easily notice electric field created by prey or threat from miles away. All the hammerhead sharks have excessively small mouths compared to other sharks located at the bottom of the cephalofoil with serrated triangular teeth. Hammerheads have wide-set eyes on the outer edges of the hammer adapted to give a wider and better visual range compared to other sharks.
Well, most of this secret lays in their feet. They have long toes with fringes of skin in between them that unfurl in water, this creates a air bubble that prevents them from sinking. However, they have to pull their feet up before the air bubble sinks and gravity pulls them down. Strong bones was usually a good thing, but these lizards have evolved hollow bones that prevent them from sinking. Some of the secret also lies within their tail, while running they hold their tail in the air to counterbalance their upright posture and to reduce drag.
They push us to realize that we might not be the only creatures that have the ability “to solve problems, make complex connections between ideas, and survive by wits alone.” (Octopus Deploy octopus.com The growing evidence for octopus intelligence.) Upon examining their lifestyle and behavior in both the wild and captivity, we have found
The Great Hammerhead Shark has many physical attributions that make the species unique to other sharks. Perhaps its most well-known anatomical feature, the flat and t-shaped cephalophoil, aids the Great Hammerhead in catching prey. Ampullae of Lorenzini on the hammer-shaped head sense hidden prey, which especially benefits the hunting of stingrays. The variations within the cephalophoils differentiate hammerheads from each other. In addition, wide-set eyes give The Great Hammerhead shark a greater, more enhanced range of sight.
Bradbury’s Second Story It came on large, jagged toothed, yet deadly finned. It swam just below the water prowling for some fresh meat. Each fin was extended, a long extension to push water away like Moses parting the red sea. Each tooth was sharp and jagged, with rows and rows of teeth it could have been a shredder. And from the great breathing cage of the upper body those two fins pushed water out of the way, which might push schools of fish feet away.
Rough Draft Gavin Gomez Marine Bio Freytag 4/10/17 When we think of parasites our first thoughts might be about the many sci-fi concepts we see in movies, such as aliens taking over human bodies to take over the world. But in reality there are many parasites out in the world today. One of the most interesting ones that might not be so well known is the Tongue Eating Louse (Cymothoa exigua). The Tongue Eating Louse is an aquatic isopod. They will find it’s way into a fish’s mouth through the gills, suck the blood of the tongue until it wastes away, then attach themselves to the leftover tongue muscles and act as the fish’s new tongue.
Numerous types of lighting were exposed in Jaws. The natural light makes the pictures more accurate. The capability to adjust the vividness makes the frightening parts even creepier. It lets the viewers to recognize that the shark is routing towards somebody. Pair of methods are negative space, darkness, lighting for serenity.
Concerning their dietary needs, makos, because of their super speed, they can catch swordfish and tuna, which are both fast swimming fish, with teeth that are like spears. Although all sharks are different, but no matter the size of a shark it’s always covered in denticles. Denticles fit together to equip the mako with a protective coat of armor. But just because sharks are fish it doesn’t mean that their
