Starfish are very unique creatures. Starfish are sometimes called sea stars. They are classified as invertebrate Echinoderm. Starfish are commonly found in rocky tide pools and are sometimes found washed up onto shore of all the world oceans. They live in tropical waters and on the seafloors of colder climate. Starfish does not have blood. They have a water vascular system where the starfish pumps sea water through it sieve plate or madreporite into its tube to extend them.…
Was it right that the Michigan Department of Natural Resources cut Chinook Salmon stockings by almost 70% in Lake Michigan?…
The Red Cedar River is home to many interesting and unique species of organisms, including crayfish. Crayfish play a significant role in the ecosystem by serving as a food source to different organisms. By studying the factors that influence the amount of crayfish in a freshwater environment, researchers can discover more about how ecosystems persist. The overpopulation of crayfish in freshwater systems can lead to various negative impacts, such as the feeding on plants that are major food sources for different aquatic organisms and the eating of fish eggs leading to the decrease in population sizes. If there is evidence proving a positive correlation between phosphorus concentration, a chemical element that can enter water through waste or…
In America there is a number of invasive species but the one I chose the Brown trout. The Brown trout is a european species of the salmonid fish family. The Brown Trout’s scientific name is Salmo trutta. It was introduced in the mid 1800’s to america. The reason why the Brown trout is an invasive is because the Brown trout competes with other native species of fish(and obviously wins) and in some cases end up breeding with them. This has conservationist worried about the genetic makeup of the native species.…

Regeneration is the biological mechanism whereby organisms restore lost or damaged cells. This process can be used to replace organs, tissues and limbs on a small to large scale. Each type of regeneration requires different amounts of energy, resources and time. Orconectus rusticus (crayfish), compete for food, survival and mating. They have large claws that are vitally important in competition and survival. This species has developed the ability to regenerate these claws over time if they are lost or damaged. The motives and forms of regeneration in crayfish have evolved due to many factors. The effects that regeneration has are linked to the various needs that have evolved in the…
the students will be working in partners to create a painting from the book “What’s It Like to be a Fish?” by Wendy Pfeffer to express their definition of what is it to be a fish and live in the ocean. The students will be required to fully express their understanding of what it is to live in the ocean based on the book.…

The swordfish was first described in 1758 by Linnaeus. It was given the name Xiphias gladius which is still used in present day. The Family of this fish is Xiphiidae, Order is Perciformes, and the Class is Actinopterygii. When it is translated into English, the Latin term gladius means "sword", referring to the long sword-like bill the fish possesses. Some of the English common names include broadbill, broadbill swordfish, and many others. The swordfish is named for its sharp, broad, elongated upper jaw, which it uses to flail and pierce its prey of smaller fish, rising beneath a school to kill and then devour them.…
The Atlantic Ocean is an underwater world connected to gulfs and seas where various species of fish swim. Just off the coast of Texas in the Gulf of Mexico, it is the middle of April at the start of the Atlantic Bluefin Tuna breeding season. A female Bluefin returns to the same spawning grounds every year to lay eggs in the warm waters of the gulf. She is eight years old and it is her first breeding season. In the dead of night, she and her male partner will swim side by side as she lays 10+ million eggs, but these eggs have a slim chance of surviving. How slim? A one in 40 million chance of survival.…
The pesticide had an adverse effect on the hatching success of eggs and survival rate of the embryo. The pesticide was assessed for its toxic potential and it was hypothesized that in the exposure water it will be harmful to the development of zebrafish embryos and our findings prove that a very low concentration in the water in the laboratory condition does have an impact on the development of the fish embryo.…
There are many causes to the over population of jellyfish. One of the origins is pollution. When the earth is polluted it increases the number of dead zones. Zooplankton thrive in these dead zones; jellyfish also thrive on zooplankton. When there is a higher population of zooplankton, jellyfish can become bigger and in a larger population. Another cause for the spread of jellyfish is over fishing, when there is less fish that eat jelly fish, it causes their population to grow. Another problem is the warming ocean, when the water warms the jellyfish are enabled to move into new areas.…
