Its body is slim and egg-shaped shaped in cross section. The corner of the mouth spread out past the eye, this is why it’s called the largemouth bass. (Bailey, et al., 2004; Boschung, et al., 2004) Young largemouth basses eats zooplankton and insects that is in the marine.
A sharks diet is very interesting. The biggest sharks eat baby fish, shrimp, plankton, and many tiny animals. Some sharks eat bony fish, squid, and can also be cannibalistic. They usually feed on smaller sharks. Great White sharks eat fish, and as they grow start to eat seals and walrus.
Most animals in the deep sea can only detect blue light, as it’s wavelength can penetrate water the furthest, and therefore tend to bioluminesce in blue/green colours. However, some organisms have taken advantage of this fact. Dragonfish have red bioluminescent “searchlights” under their eyes so that they can identify organisms of the same species, attract mates, hide from predators and hunt unsuspecting prey who cannot detect their light. This red light is a result of fluorescent proteins which can change blue biolumenescent light into
This information appears to be encouraging the reader not to boycott seafood because the seafood is becoming more and more sustainable. However, the point of the boycott was to stop the hunting of harp seals; if people wanted to support the swilers, they would not boycott in the first place. This becomes red herring information (Henderson, 2013, p. 52) because it takes the focus off seal hunting, and provides irrelevant
Whether there is any significant impact of the existence of sharks is a non-debatable issue, but two diverse views concerning the issue On the one hand, Sharks are portrayed as vicious creatures who are a threat to human existence, and on the other, what is often overlooked is the vital impact of sharks on our society and the food chain, how it preserves our ecosystem to where it stands today. Consequently, due to corrupt human nature, the population of sharks is declining substantially. This essay will exhibit many arguments, including: the social ,economical, political and environmental impacts of sharks, while favouring their existence and display how corrupt human nature is simply disposing of this valuable creature. Sharks have many positive
As I mentioned earlier, parasites live on the gray whale which give the whale a crusty, rocky looking effect. This is an example of parasitism. Another symbiotic relationship in my biome is a shrimp and sea cucumber. These two animals are common to a lot of ocean along with the Pacific ocean. The shrimp rides on the back of the sea cucumber, while the shrimp gets a ride, the sea cucumber could care less.
Atlantic Bluefin tuna (Thunnus thynnus) Introduction: The Atlantic bluefin tuna (Thunnus thynnus) is a pelagic and schooling fish that is also known as the northern bluefin tuna, giant bluefin tuna. The species is the largest member of the Scombridae family and one of the largest bony fishes. Bluefin tunas are known to swim long distances and usually at high speed of up to about 1.5 knots and can also dive as deep as about 900 meters. The average lifespan of bluefin tunas is 15-30 years with up to 50 years for very large specimens. Description: Atlantic bluefins are dark blue to black blue above and silvery underneath with a gold coruscation covering the body and bright yellow caudal finlets.
They lack digestive tract, mouth and senory organs, they have unique body extension called microtiches which help in absorption of host nutrients. They have scolex which is provided with suckers and often with hooks for attachment. More than 10,000 species of tapeworms are known to science. The most common species of tapeworm in humans are fish tapeworm, beef tapeworm, pork tapeworm, dwarf tapeworm, dog tapewom, uniocular hydatid and multiocular hydatid. 1.
They have well-developed and symmetrical gills over which drawn water flows. The flow of water carries the waste and reproductive products. Movement: Although abalones occur in the same place, they may use their muscular foot with its suction power to move, cling and stay tight with the substrate surfaces. Feeding habits: In nature, abalone eats marine algae with a particular preference to large brown algae such as giant kelp and other kelp species. While juvenile abalone grazes for algae, diatoms and bacterial films, adults rely on drift algae, and if food becomes scares, they move after their food.
