In 1981, George Streisinger and his colleagues began to use zebrafish as a model organism for research. Since then, they have become a popular model organism for biomedical research. Zebrafish primarily have been used to study vertebrate development, evolution, genetics, and disease. Zebrafish are popular as pets and genetically modified, glow-in-the-dark zebrafish have been developed for the aquaria trade as well. Zebrafish have many attributes that make it a popular model organism for biomedical research.…
Captive Killer Whales Blackfish is a movie about an orca named Tilikum who was captured at a young age and taken to perform at Sealand. Within a year and a half he was moved to Seaworld for breeding purposes and because Sealand shut down. Tilikum soon became a great attraction and everyone wanted to see him and all the trainers wanted to train him. They all thought Tilikum was an excellent whale, but that is because they were never told that anything bad happened.…
This species was introduced into the UK in the 1970s as food source. It spread quickly up and downstream and human introduction, although illegal, is still continuing. It may travel over land to colonise near freshwater. Its negative impact is mainly due to the loss of the native crayfish species, the white-clawed crayfish (Austropotamobius pallipes) through spread of disease and direct competition. Furthermore, the Signal crayfish is also impacting the river banks as it uses to burrow into them, creating instability of the vegetation and the ground.…

From source 1: The Monster goldfish is a normal goldfish that got dumped by the owner but then grew and grew and grew until it was huge!…
The invasive effects of Dreissena polymorpha on native mussels within the Great Lakes region The Great Lakes area once supported an abundant number of freshwater mussels (Mollusca: Unionacea). The invasion of Zebra mussels (Dreissena polymorpha) has decimated these populations, by outcompeting native mussels in dispersal rates, and reproduction, due to enhanced survival mechanisms. Understanding the mechanisms that have allowed Zebra mussels to out complete native fresh water mussels, will provide insight into possible mechanisms that can stop the spread of Zebra mussels, and help with the survival of native mussels. Griffiths et al. conducted length-frequency analysis of the Zebra mussel population, before 1988 (prediscovery) and between…
Based on a documentary called "BlackFish", SeaWorld lies about many things. Now, imagine being on a still boat in the Pacific Ocean, off the coast of California. A seal is swimming around your boat. All of a sudden you see a group of killer whales (pod) swimming furiously, with one thing on its mind. Food.…
Silent but deadly. It might be too late to save the aquatic animals in the Great Lakes from migrant species that have come to take over, and make a new home. Shipping vessels coming from other waters carry many unwanted guests, known as invasive species, to make home in our waters in the United States. Invasive species hiding in the ballast of ships entering the Great Lakes damage the Great Lakes’ ecosystem.…
When people think of the word catfish, the first thing that probably comes to mind is a fish with barbells that dwells at the bottom of murky waters. On MTV, a Catfish is someone who uses social media to create a fake online persona, in hopes of pursuing a romantic relationship. The reality show Catfish itself is actually based on the 2010 film Catfish, involving a man and a woman who develop a romantic relationship via Facebook. When they finally met in person, the young man Nev, soon realizes that he was a catfishee, instead of someone who had found his true love. His brother filmed the whole documentary, with no idea that it would soon become a success.…
The Lionfish is a venomous predatory fish that carries the potential to impact the marine ecosystems of south Florida. Past evidence suggests that the proliferation of lionfish may help decline th eexistence of native species of commercial, recreational, and ecological importance. In addition, lionfish stings are painful and occasionally result in serious injury. The Lionfish is a non-native invasive fish, it was likely to be released on purpose from people whom no longer wanted them as aquarium pets. The swift and warm Gulf Stream, which likely transported buoyant lionfish eggs and larvae from Florida northward, helped the lionfish's Atlantic journey.…
Ever since the release of Blackfish, SeaWorld has come under harsh criticisms from animal rights activists. The question is, who do we trust? A multimillion dollar company or people who are extremely passionate about animals? SeaWorld was originally planned to be an underwater restaurant.…
Zebra mussels are a small bivalve mollusk that originate from Eastern Europe and Western Asia (kdheks.gov). Zebra Mussels get their name because, of their cream and black stripes on their shells. Zebra mussels have small dime sized, triangle shaped shells. Zebra Mussels in large numbers are known as colonies and can contain millions of individual mussels. They’re known as an exotic invasive species because they are nonnative to US waters.…
Lionfish or pterois miles have invaded the Atlantic coast line. Their original habitat is in the Indo-Pacific Ocean. They are poisonous and have spines were their venom is kept. They live in warm habitats like the tropics and are found in reefs and dark underwater crevices. First, lionfish had lived in the Indo-Pacific but, due to a hurricane and water and aquarium trades they found themselves in the Atlantic Ocean.…

This invasive species can be found across the eastern coast of the United States. Lionfish prefer to live near coral reefs and in rock crevices.…
“The Blue Lankia starfish is so distinct when It comes to salt water that you can’t find those anywhere else. I got started around 1992 and the country was in a recession and there were really no jobs, especially for ex-military. Diving was a passion of mine and this hobby was a passion of mine, so I was able to keep things that others weren’t able to keep and I had special permits from the government to keep things that weren’t typically allowed just to see if we could keep them alive to pull them off of the protect list. Doing so we were able to grow them and propagate them, so many things weren’t touchable became a hobbyist pet.…
