The purpose of the experiment was to understand how strong a bessbug by using weights and observing the time the best bug takes to travel to a certain distance.
The cuttlefish is an amazing marine animal, one of the most intelligent invertebrates. It is not actually a fish though, it is in the category sepiida. There are over 130 different species of cuttlefish. This mollusc has a very large brain and a very unique eye. It has 8 arms and 2 tentacles that have suckers on them so they can grab their prey. Sometimes the cuttle fish will use its arms to walk across the ocean floor to hunt food and to keep away from larger predators. Their favorite food is crab, but they also eat small fish, shrimp, and some are even carnivores. They have a fin like thing that goes around their bodies so they can swim.
While nature has bestowed us with beautiful wildlife and a multitude of bizarre, beautiful yet terrestrial and aerial species, it has not boycotted the aquatic fauna too. From scary to intriguingly beautiful, here’s a list of ten amazing organisms inhabiting the dark depths of seas and oceans.
The ocean is a giant body of water that is home to all types of fish. The ocean provides a rich environment for a plethora of animals from the tiniest of fish to the enormous whale. In the ocean, these creatures live and explore. Some of them must hunt other fish in order to survive, which means that others must try to avoid predators. Nature has provided all of these animals with a unique capability to survive. The ocean abounds with interesting animals of all shapes and sizes that have their unique appearances and habitats at different depths of the sea.
The next system I dissected was the respiratory system. My first task was to find the trachea as well as the esophagus. My goal was to compare the structure of each. I found the trachea to be wider, stronger, and it had a bumpy surface. The structure of the esophagus is small, but versatile which allows it to move easily. It is also flat and full of muscle. This allows for food to digest before it enters the stomach. While dissecting the respiratory system, I continued to study the trachea, as well as the lungs and bronchi to see how their structure related to their function. . As mentioned above, the trachea is a wide and strong part of the respiratory system. The structure of the trachea is related to the function because it allows for the fetal pig to receive proper air passage through the lungs. Next, the structure of the lungs consist of four lobes in the right lung, and two or three lobes in the left. “The lungs in the fetal pig are small and fairly solid because they’ve never been
The process was replicated by thirty groups and the following process was kept constant by each group. Thirty daphnia of various sizes were measured through the aid of a light microscope and micrometer scale. These daphnia were then placed into a tank containing a single bluegill fish, which had been kept unfed for a constant amount of times. When the bluegill fish had eaten ten of the thirty daphnia placed in the tank, it was immediately removed from the tank and placed in a beaker containing a narcotic based anesthetic poison. Following the death of the fish, as indicated by the complete halting of its movement the fish, the fish was dissected in order to remove the eaten daphnia and once again measure them using a light microscope. The dissection process consisted of making a sagittal plane incision stretching from the anus to the throat and removing the ten daphnia from the fish’s intestinal
The three spined stickleback fish has many unique traits. some of the most notable structural adaptive traits of this specie are the three spines and body armor. The three spines are sharp and located on the back forward of the dorsal fin. The lateral bony plates are located on each side of the body. These structural armors projecting from the back and pelvis can simultaneously flare out when the fish feels threatened as a defense against predatory vertebrates making it difficult for predators to swallow them. With the back spines pointing directly upward and the pelvic spine pointing out at a perpendicular angle make it difficult for a predatory fish that catches a stickleback to swallow the stickleback. This added benefit allows the fish

Sharks are enormous mammals that live within the deep ocean waters all over the world. There are several different sharks in many parts of the world depending on temperature, seasons, food and more. Every shark is unique in their own way and every species is unique as well. Although humans view them as vicious creatures that are out to harm us while we are at the beach on a sunny Sunday, these creatures are just trying to live like any other animal in this planet. They each have different defense mechanisms, and physical features that all them to live and continue reproducing. For example, sharks have different type of dorsal fins, teeth, hunting strategies, movement patters, and mating techniques. All of this is important to the survival
As my team and I discovered a new fossil in our excavation project, the unknown site yielded the skull of a mysterious specimen. Our goal as reputable anthropologist was to analyze the specimen to the best of our ability so our team can provide the most probable and reliable taxonomic identification. In order for us to effectively interpret the results our experiment yielded, we needed to review our knowledge in human evolution. The field that uncovers the mystery of the evolution of humans is paleoanthropology, the study of human evolution through the fossil record.
The Port and Starboard Lightfish looks like a Pineapple. It is very exciting to observe this fish and its unique features. The Port and Starboard Lightfish is also known as the Knight fish, the Coat of Mail Fish and the Pineapple fish. It is commonly seen in harbors and reefs in the Queensland in Australia. The Port and Starboard Lightfish prefers to live in waters that are about 6 to 200 meters in depth. This fish can grow up to 8.7 inches and it is plump in size. Also, it can bring that spirit of adventure into your tank.
After a plethora of studies made we know quite a bit about the ocean and the creatures that live there. We know who is the prey and who is the predator, what temperature some live in, and where they live. We know so much about the ocean and its inhabitants, but we also don’t know enough. There is more in the ocean than the things we’ve seen and studied. There’s things deep down in the ocean so deep that light from the sun doesn’t even reach it. In this deep abyss, there lives fish we have come to call the Chimaera. These fish are found in the deep water where they hunt with their tooth plates which they use to grid into hard bodied prey. Today I will be giving you some information on Chimaeras to increase your knowledge on them and to understand
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. Its coloration varies from brown to light gray on the dorsal side and a white underside. The sharks have curved pelvic fins and an asymmetrical caudal fin for smooth, quick swimming. The distinguishing characteristics
Above is a map highlighting where dugongs are currently located in the world. They can be found from East Africa to Australia, including the Pacific and Indian Ocean and the Red Sea. The largest population of dugongs are found in Australian waters. Specifically in the northern part of Australia, between Shark Bay and Moreton Bay. Dugongs tend to live in warm and shallow coastal waters. Large numbers can also be found along inshore islands and in shallow mangrove channels. They live where seagrass is plentiful as that is their main source of food and nutrition. They usually inhabit waters at an average depth of around 10m and sporadically dive down to up to 39m to feed. The activity the dugongs are doing determines the habitat. For example, for calving a potential or suitable habitat would be the shallow estuaries and tidal sandbanks. Whereas for mating, they can be found in lekking habitats.
In every part of the surrounding, in which humans dwell in, no matter in water, land, air, or elsewhere, there reign tiny yet complex lives. The in depths study of these living organisms bring human a face to face consequence with an astounding miracle of the creation of God. The astounding part of the living organisms have led us some understanding of the awe-inspiring structure of every life from as small as 0.0000001 to over 0.1. These photomicrographs unveiled the miracle and astounding lives as illustrated below.
