I believe that a goldfish’s memory span is much longer than three seconds, and I believe that they have the ability to remember complex tasks. From growing up in the Bahamas, life was and is circulated around the water. From growing up in the water you are able to notice patterns in natural fish behaviour. When spearfishing you can notice that fish automatically dart into holes for protection. When fish such as the Nassau grouper travel miles to breed, and then return to the exact reef that they left, that cannot be trial and error.
Is it possible for us to eat this kind of fish? Well, this fish is usually jutted to decorate our aquarium. It is not for eating because of the tiny body. We will not get full and stop to eat if this kind of fish is in our menu. Besides, the cute side of their body makes us not easy to cook it.
Adaptation to live in the habitat lack of oxygen A. Crayfish: Crayfish lives in fresh water stream, which is an aquatic environment. The oxygen level in fresh water upper stream is higher than the lower stream, but the oxygen concentration is still low. The gills of crayfish are much bigger than the size at first glance. They occupied under the cephalothorax carapace in branched-shape and provided a large surface area to volume ratio to carry out gas exchange. Fresh water will be pulled into the cavity by the movement of the “gill bailers”.
In doing so, it will provide a healthy, and clean environment for it. Both betta, and goldfish are easy to maintain and care for because neither of them require any past aquatic experience. Since a goldfish requires to eat a lot, and is a messy eater, you would see that the tank gets dirty quickly. Furthermore, if there is decorations in the tank like rocks, mini sculptures, fake plants etc. will make the cleaning hard.
It is continuously growing and all cells preserve the aptitude to develop into whatever section is considered necessary. several variety of starfish encompass the ability to redevelop, which means that if an arm is lost, it is able to grow an entire new limb in given a period of time. A small number of species of starfish can again grow a complete new disc or echinoderm from a single limb, while other species require a part of the central disc to be attached to the dethatched part. An echinoderm is a male or female starfish. A Starfish reproduces asexually by a method known as spawning.
In my life I’ve been freshwater fishing and saltwater fishing many times in a variety of places. Throughout my experiences I’ve realized that a large amount of people consider all types of fishing to be the same, this is not true in many aspects. It can be divided into two categories: saltwater fishing and freshwater fishing. I’ve caught a 40 inch northern in Canada (freshwater) which is a big fish, and it only took me ten minutes to get it into the boat. However, I caught a 42 inch shark in Florida (saltwater) which took me 20 minutes to reel in, and that is considered a small fish.
The grayscale color of the background could be representing polluted or unclean water. The goldfish stands out in the image because it is the only colorful object in the fishbowl. The faucet’s color is also dark gray, which stands out in this im-age because it is right next to the fishbowl which the color is
Marine aquaculture is the farming of seafood species that are indigenous to the ocean. According to the National Oceanic and Atmospheric Administration (NOAA), “U.S. marine aquaculture primarily produces oysters, clams, mussels, shrimp, and salmon as well as lesser amounts of cod, moi, yellowtail, barramundi, seabass, and seabream.” Although marine aquaculture can take place in the ocean, using cages on the seafloor or in suspended water columns, most of the aquaculture systems in the U.S. are man made on land, using a recirculating system that reduces and recycles water. But like other forms of farming, aquaculture can lead to negative effects on the environment. The impacts vary upon the type of organism being farmed/raised and the type of system being used.
They are originally from North America and live in places such as rivers, streams and lakes. Bluegill can grow up to around 30 centimeters, but most of them are about 20~25 centimeters (“Bluegill Fish”, N/A). They mainly eat small insects and other small fish. The bluegill eat small animals to sea weeds, and they are strong fishes. Bluegill spread fast because the parents protect their eggs so other fishes can’t eat them.
