Crayfish are decapods pertaining to the phylum arthropoda, which are invertebrates and contain an open-circulatory system.1 The system works by the hemolymph getting re-oxygenated in the gills before being transporting to the heart by brachio-cardiac veins and then pumped to sinuses that bathe tissues with oxygenated hemolymph.2 The crayfish contain a neurogenic heart that depends on neuronal input from cardiac ganglion.3 The neurogenic heart requires nerve impulses to produce contractions in contrast to a myogenic heart that can contract independently from the nervous system.3 The crayfish heart will beat due to the reaction of the ganglion to stimuli in the environment.4 Stimuli will affect the autonomic nervous system in the crayfish that control involuntary actions such as the heart rhythm.4 Neurotransmitters are the chemical signals in which the nervous system regulates both heart rate and contraction.3The autonomic nervous system breaks into two categories as parasympathetic system that is involved in relaxation of organs and the sympathetic system that will stimulate increased activity. Neurotransmitters can either increase or decrease heart rate by altering the patterns in neural activity of the heart.4 Crayfish are poikilotherms, which means they cannot metabolically thermoregulate thus conform to the ambient temperature in the water.
This could be due to enviornmental reasons. Due to the enviornment brine shrimp usually have to grow is due to natural selection. Through natural selection they are able to pass down genes and carry ablitly to reproduce. Unlike in our experiment where we just had a solution and them in a petry dish. Brine shrimp can live in an enviornment
Ghost shrimp are high in natural oils and fats, beneficial for coloration and development of seahorses. Ghost Shrimp have a much lower risk of carrying disease than other live feeder species and are also very effective at actively reducing nitrates within the water (Ghostshrimp). Reducing nitrates and keeping the water clean is very important for seahorses as I will explain
Even though mantis shrimp are colorful and interesting to look at, they are very, very dangerous to handle and should be avoided without proper handling equipment. Some may call them a “living knife”. Fishermen see the shrimp a lot when getting their nets out of the water because they like living at the bottom of the ocean and the nets ruff the bottom
Background In the story of SpongeBob Squarepants, it takes place in the underwater city, Bikini Bottom, and describes many of the underwater creatures that living in the same place and how they association with each other. These underwater creatures are SpongeBob squarepant , Patrick Star, Squidward Tentacles, Eugene Krab, Sandy Cheeks, Gary the snail, and Sheldon J, Plankton. The story shows their relationships and correlated to the fun events that happen in the Bikini Bottom. In this study, the focus on the Eugene Krabs, also called Mr. Krabs, who is a businessman and loves money too much to the point that he has to take money in baths, and constantly counting money back and forth.
Blackfish The documentary Blackfish, directed by Gabriela Cowperthwaite released in July 2013, explores the mistreatment of killer whales and the relationship between the killer whales and trainers as well as the significant problems of the sea-park industry, with a focus upon SeaWorld. Cowperthwaite positions the audience to feel sympathy towards the killer whales by making deliberate choices in sound, visual, language, and structure through the representation of trainers as unprofessional, and whales as mistreated, also experts as reliable information source. Firstly, Cowperthwaite uses effective language techniques to position the audience to view the trainers as undertrained and unprofessional.
I’ll give you an example. Take a spider and a starfish. Spiders have a central nervous system. Starfishes have a decentralized nervous system. Next thing you have to think up is the analogy with business organizations.
The habitat of the moonfish is about 200 meters below the surface in the more tropical oceans. Moonfish tend to be more solitary, but are known to school with tuna and have no identified migration pattern, though they are commonly found near Hawaii and West Africa. The majority of the moonfish’s diet consists of squid and krill, as well as some small fish and eats by using its mouth. They catch their prey by diving to about 650 feet below the oceans surface.
Sea Sponges are animals that live in the ocean floor. They are the simplest animals and can produce asexually and sexually. They are favored over synthetic sponges because of their softness and their ability to stop mold, mildew, and bacteria. Sponges are harvested by divers who cut sponges off of their bases with hooks. AFter the divers cut the animal off of its base the sponge will grow back on the same base in a few years.
Picture this, a Hermit Crab and Sea Anemone, they help each other, the Hermit Crab uses pinchers to tap the Sea Anemones. The Sea Anemones attaches to the Hermit Crab 's shell, the crab gives the Sea Anemone a ride along the bottom of the ocean. In return for the free ride the Sea Anemone protects the Hermit Crab from Octopuses and other predators. The Hermit Crab gives protection from starfish and other attackers. As I have explained the relationship of the Hermit Crab and Sea Anemone, they
In the short story “A perfect for Bananafish” by J. D. Salinger, Seymour’s comfort around children rather than adults represents the conformity that adults have created for social standards when they don’t understands they judge. When Seymour and Sybil meet at the beach, Seymour tells Sybil that he likes her blue bathing suit, which is actually yellow: ““It's a blue bathing suit.” ... “this is a yellow”... “you're absolutely right.
Female blue crabs lay 600,000-8 million eggs at one time. By definition, an ecosystem is all the living things and nonliving things that live in a specific area or environment and interact with each other. The Neritic Zone is located on the continental shelf. Much of sea life lives in this zone because it has well-oxygenated water, low water pressure, and a stable temperature. The Neritic zone goes down 200 meters or 656 feet.
Scrimp scampi is a dish that has migrated from the northern regions of Italy. Scampi’s are tiny lobster-like crustaceans with light pink shells that are also known as langoustines. Shrimp Scampi is a dish that tastes extremely delicious. Preparing shrimp scampi does not require as much work as people make it seem. Follow these simple steps and you will have the best shrimp scampi for yourself.
Marine organisms are animals, plants, and other living things that live in the ocean. A Marine biologist is a scientist who studies marine organisms and studies the bodies, behavior, and the history of marine organisms. They also study how marine organisms interact with each other and their environment. I have chosen to research about Marine biology because I would like to learn about sea life, the ocean, and its surrounding environment. To start off, a Marine biologist might study coral, crabs, fish, microscopic marine organisms, sea stars, seaweed, squid, or whales.
Coral reefs. By: Valentina Sarria. Coral reefs are one of the most diverse and complex habitats. They are one of the most interesting and colorful ecosystems found in the marine environment.
