Seahorses Did you know that seahorses are the only sea animal where the male gives birth instead of the female. What about the fact that seahorses can eat up to 3,000 shrimp per day. While they are sleeping they wrap their tails around seaweed so they don’t float away. Of course, seahorses are very interesting and one of the most interesting animals in marine life. This paper will explain the birth,food,and adaptations of a seahorse. First of all,this is all about a seahorses…

“Take pride in how far you have come, and have Faith in how far you can go.” – Christian Larson. This quote eloquently explains the old man's adventure he had with the marlin in the book The Old Man and the Sea by Ernest Hemingway. To go more in depth, in his journey with the marlin he took in pride in never giving up on trying to catch the fish even with the ongoing pain he had to deal with. Along with pride, he also had faith by never giving excuses to himself to give up, and always thinking…

The reading states that zebra mussel has long been spreading out from its original habitats and has now reached parts of North America. therefore it poses a serious threat to freshwater fish populations in all North America and provides three reasons for support. However, the professor explains that zebra mussel is not likely to the serious threat to the freshwater fish population and refutes each of the author's reasons. First, the article claims that it is possible that zebra mussel…

14.1 The Big Picture 4. Yes, it is likely that there will be competitive exclusion between the fish and ducks. Competitive exclusion does not only mean that one species is killed off it also means that it can “also result in two species sharing different parts of a niche”(pg.249). The ducks and fish don’t share the same ecological niche which is “the part of the environment that a species uses to survive and reproduce”(pg.248). This is also proven by the fact that it states in the textbook that…

Baleen whales undergo the longest annual migrations of any animal (Rice and Wolman 1971, Stone et al. 1990, Rasmussen et al. 2007). The function has generally been accepted as an evolutionary response to the need to feed in colder waters and reproduce in warmer waters (Corkeron and Connor 1999, Learmonth et al 2006). The location of feeding and breeding grounds along migration routes were initially inferred from stomach contents of stranding data and whaling logs (e.g., MacKintosh 1945, Scammon…

Eurasian Minnow (Phoxinus phoxinus) is a 14cm long “Demersal; potamodromous fish that can live up to 11 years. “Originally, minnows were spread because fishermen used them as live bait for catching species like brown trout (Salmo trutta), Arctic charr (Salvelinus alpinus), perch (Perca fluviatilis) and pike (Exos lucius) (Huitfeldt-Kaas 1918). This practice is considered to be the main reason for most introductions throughout the 1900s. However, minnows have also been accidentally introduced in…

The salmon leukemia virus is one that attacks the immune system and slowly causes the fish to die of other causes. This disease prevents the fish from fighting any other disease it might catch and begins to deteriorate the internal organs. Alex Morton began to show her findings that these fish from the Frasier River contained the virus and she was able to trace them back to the farms she soon became ostracized and put on gag order. To protect the interest of the salmon farm industry the…

The trying journey Ever get grossed out? Well…….Luckily you're not Cabeza de Vaca! He was stranded on a raft for so long that he had to drink rationed water out of an old horse leg. Cabeza de Vaca learned great wilderness skills while he was stranded and had few supplies.Before they got separated, they had more than 300 men on that boat. Narvaez had ordered 300 men off of the boat to go inland and search for treasure.That would prove fateful as they would never see their ships again. After…

The species I chose was Pterois volitans, which is commonly known as a lionfish or red lionfish. They are characterized by alternating white and red/brown stripes and contain venomous spines all over the body. Lionfish can grow up to 18.5 inches in length and are a species native to the Indo-Pacific region. Economically speaking lionfish are not regularly used in the seafood business, but are a huge part of the aquarium trade (Robbins). Due to the spines described above, there does not seem to…
