These lion fish prey on all different types of animals, such as: crabs, shrimp and smaller fish; and have very little amount predators giving them the place in the higher levels of the food chain. Since it is so high in the food chain and preys on almost anything, it has managed to survive in the Atlantic Ocean perfectly. In the Atlantic, lion fish are defined as invasive species, which means, "a non-native organism that has intruded into an area and may have serious detrimental effects on native organisms, the local economy, and human health". sadly many accidents have led to the invasion where the lion fish has spread all across the Caribbean Sea and up North in places like Rhode Island. It is hypothesized that the origin of the whole problem came from only six lion fish that were accidentally released from an aquarium to the Atlantic Ocean in 1992 during hurricane Andrew.
The hunting shark will swim in spirals, thereby eliminating the currents that don't carry the scent of blood and following those that do. Diffusion not only happens in liquids but takes place in gases too. It helps Predators like tigers to detect their prey. Scent molecules of the prey spread gradually from the highly concentrated source moving randomly and quickly in the surrounding air where there is low concentration .these scent molecules travel faster than those in water because of the surrounding air (gas). Gas particles are further apart from each other than those in water so this helps them move more freely in a quicker time.
The invasion of the Coqui frog species threatens Hawaii’s environment, economy, and health, therefore; education of the species is necessary. About Coqui Frogs The origin of Coqui frogs is rooted from Puerto Rico, however; in the 1980s the species had invaded Hawaii through transported potted plants. Coqui frogs are non-venomous; they are light to dark brown in color and commonly have a stripe down the middle of its back. The Coqui is rather small growing to a max length of two inches. At dusk males will come out to begin a high shrieking call of “ko-kee” to attract females.
Levels much below 7 cause moulting and shell hardening problems in yabbies. Low calcium levels (hardness less than 80ppm) has the same effect. Behavior Yabbies can be aggressive and cannibalistic under certain conditions. High survival and good growth can still be achieved when some form of shelter is available. Although redclaw are less aggressive, shelter is still required to achieve uniform growth rates, as large crayfish dominate small crayfish.
The Great Hammerhead Shark Sharks are one of the most feared sea animals. They live in oceans across the world but are most common in tropical waters. There are over three hundred fifty species of sharks. They can be broadly categorized into the following four groups: Squalomorphii, Squatinomorphii, Batoidea, and Galeomorphii. The shark family Sphyrnidae that includes the Hammerheads are a part of the Galeomorphic classification.
The dolphin can defend its self but with the skills of the shark, it’s not rare for the dolphin to fail. But also targeting a single adult dolphin can be also dangerous for the shark of similar size. Certain killer whale populations may also prey on dolphins, but this seems rare and others may swim with dolphins. The EXACT estimation population of the bottlenose dolphin is not known. But there is much different estimations.
Escaped farmed salmon are then capable of spreading these infections to wild Pacific salmon populations. Of course, the big question is, “What can we do about these problems?” The best approach according to Frazer & Lewis (2008; as cited in SeaWeb, 2007), would include “… locating sea cages very far from wild fish” (Abstract), or using a “closed containment” (p. 2) system in order to isolate farmed fish from wild fish. Unfortunately, both options are more expensive than popular methods of aquaculture. Short-term gains from aquaculture and other human interventions appear to outweigh short-term losses, so industry has little incentive to follow more sustainable practices. If these practices continue, then long-term losses may result in the extinction of multiple Pacific salmon species
Finding where the fish are, is the first thing to make a good bass angler. Knowing the structure of the bottom the body of water you are fishing is important. Bass like hiding in thick weed beds so they can ambush their prey. Or if it is the spawning season the bass will be making beds in the shallow water near the shore line. Also if there are any underwater trees or logs bass love to hangout under them.
An example of this would be that there are around six different species of mosquitoes that are identical but cannot all interbreed with one another because they breed in different waters. Therefore it creates more species of mosquitoes. Another contributing isolating mechanism to speciation in organisms would be behavioral isolation. This occurs when courtship rituals enable mate recognition which is the way one animal behaves to attract another animal to want to mate. A great example of this is Blue footed boobies.
Jessica DeLosh English 101-006 Mrs. Alderfer April 27, 2015 Rhetorical Essay Orcas: Captive Beauties The film, Blackfish is a documentary based on the true factual information about the effects on orcas while in captivity. The film reveals SeaWorld’s behind the scenes of what actual goes on at everyone’s favorite amusement park. As the documentary goes on, more is revealed about the emotional and physical pain the orcas endure. The film Blackfish effectively convinces the audience that orcas should not be held in captivity because of the evidence discrediting SeaWorld. The use of 911 calls and personal testimony about capturing whales help reveal emotional appeals.
