To be more specific, benthic organisms are known as benthos (Benthic). Benthos can consist of crabs, lobsters, sea
organisms that live in this deep part of the ocean are called benthos. Some examples of benthos are starfish, sea cucumbers, oysters, and clams. There are many different geographies to the be if ocean such as trenches, mountains, and volcanoes. The benthos have their own food source which is called detritus. Detritus are dead/decaying matter from algae, plants, and many animals that fall to the bottom of the ocean. You can also call the benthos scavengers since they are eating the dead organisms. They
produced extremely varied samples of organisms from deep-sea communities. The epibenthic sled permitted researchers to observe organisms that had previously gone unnoticed; unknown to the scientific community was a varied population of macrofaunal benthos inhabiting the bottom sediment, in addition to new species of polychaetes, crustaceans, and mollusks. Further sampling in the 1980’s, with the use of a box corer, revealed an astoundingly heterogeneous population of benthic organisms equal, or perhaps
other words, how do some diatoms stay afloat, while others stay attached to the benthos? Some of the diatoms are able to stay afloat because they have more surface area, meaning they have extended body parts that catch the water and make them sink much slower. While other types of diatoms stay attached to the benthos because they don’t have the longer appendages and therefore sink faster. So they have to make the benthos their home. Which group of phytoplankton contains many members that produce light
Humans have spent billions of dollars, and millions of man hours conducting research of sea life. As technology advances and the ability to stay underwater for longer periods of time become available, new information about sea life and there ecosystems surface. The vast ocean covers more than 70 percent of planet Earth’s surface (NOAA). However researchers and scientists have explored less than five percent of what really lies under water (NOAA). Leaving behind and amazing ninety-five percent left
The giant pacific octopus is in the kingdom Animalia because it is multicellular, eukaryotic, and has no cell walls. In addition to this, the giant pacific octopus reproduces sexually and has cells that are used for specific functions. (Kalupa, 2012) The octopus is in the phylum Molluska. It is under Molluska because the octopus has a soft body (mollus meaning soft), and is a cephalopod. It also has bilateral symmetry. (Kalupa, 2012) The giant pacific octopus’s class is Cephalopoda. This means “head-foot”
Ecologists use technology like quadrats and transects to sample plants and other plant life. Invertebrate ecologists use technology like Berlese-Tullgren funnel and light traps to measure to sample on land, then turn to wilding samplers, benthos grabbers, and various nets to sample land in aquatic habitats to collect faunal samples. Vertebrate ecologists on the other hand use cages and pitfall traps and other traps to capture most animals they wish to detect like rabbits or raccoons. Some
Marine Biology of the Jurassic Period The Jurassic period is known as one of the most interesting periods of time in earth’s history, mainly for the awe-inspiring creatures many of which have gone extinct, the most remarkable being the dinosaurs. Life in the ocean during this time was also extremely diversified and amazing for the creatures it beheld. The Jurassic occurred from 199.6 to 145.5 million years ago, following the Triassic Period and preceding the Cretaceous Period within the Mesozoic
Abstract One of the main challenges that face the environment today is the threat of plastic materials in the environment. All forms and sizes of plastic are harmful to the environment; this paper looks at the effects of microplastics which are small forms of plastic that are at least 5mm in size. Due to their small size, the microplastics end up being ingested into the bodies of aquatic animals causing health consequences that are uncertain to the organisms. This review focuses on the susceptibility
A Colorless World: Coral Bleaching I’m sure you’ve all heard of bleaching. You bleach clothes to make them whiter, you bleach bathrooms and kitchens to disinfect them, but have you ever thought about how bleaching may occur in the ocean? There is an event that occurs in coral reef ecosystems called coral bleaching which is a result of prolonged exposure of coral to extreme temperatures in the ocean. Certain symbiotic algae (zooxanthellae) attach to coral and actually give the coral its color
Climate change: it has become a touchy subject in today’s society. Some claim that it “isn’t real or isn’t happening” despite the overwhelming evidence that proves it is affecting the planet. Human activity has led to a startling increase in atmospheric carbon dioxide levels. For the past 650,000 years, the atmospheric level of carbon dioxide had been relatively steady, never reaching above 300 parts per million. In the past 50 or so years, the rate has skyrocketed from 315 to 400 parts per million
The Carbon Cycle is a major component of the Biogeochemistry of the planet. Across the Lithosphere and Biosphere, carbon plays a large role in the creation of biomass as well as decomposition. The carbon cycle in the hydrosphere, particularly in the oceans, is not as well known. We do know, however, that oceans play a critical role in the carbon cycle because it acts as a large sink of carbon as it is rapidly exchanged with the atmosphere. The carbon cycle in the oceans involves both organic compounds
In 1804 a great Gothic-romance writer by the name of Nathaniel Hawthorne was born in Salem, Massachusetts and was determined to make the 18th Century aware of the deep and dark desires that are present in every person’s mind. Hawthorne himself once quoted that “easy reading is damn hard writing.”(Hawthorne, 1849) but through frustration and angst Hawthorne created a selection of metaphysical poetry and a few longer works, one of which being the infamous “The Scarlett Letter”. Hawthorne’s style
Introduction During the summers the oxygen content atop the water normally has a salinity level consistent with “more than 8 milligrams per liter”; but when oxygen content drops down to “less than 2 milligrams per liter” the water is then known to be in hypoxic state (CENR, 2000; USGS, 2006). Hypoxia is the result of oxygen levels decreasing to the point where aquatic organisms can no longer survive in the water column. Organisms such as fish, shrimps, and crabs are capable to evacuate the area
