Biology Excursion Question Using data collected on field trip and two named animals, explain the relationship between the distribution and abundance of these two organisms and the abiotic features of the rock platform. There is a close relationship between the abundance and the distribution of organisms living amongst the long reef platform. Abiotic features such as temperature range, salinity, Ph. levels, turbidity, water availability effect the distribution and abundance of aquatic sea creatures living in the area. Some of the organisms such as Tesseropora Roseas (Barnacles) and Knobbly Winks have different adaptations, which allow them to survive in these harsh conditions.
They have two pectoral fins that are forked in on the sides which enable them to control their direction of movement. The fish also has a moveable jaw which allows it to bite into coral. The moveable jaw is small but strong and bony. Coloration is a important component to the fish. The Megladon fish has disruptive coloration, with its spots and stripes it is able to confuse their predators.
Younger lionfish have a unique tentacle above their eye sockets, which differs in appearance between species, but studies show that this tentacle has evolved over time in each species serving to attract new prey. Juvenile lionfish eat mostly invertebrates, but shift their diet to fish as adults and eat reef fish. Adult lionfish spread their pectoral fins and use them to "herd" prey. This is a very effective predatory style because it is unfamiliar to native Florida fish. However, Lionfish can have negative effects on the overall reef habitat as they can eliminate organisms which serve important ecological roles such as herbivorous fish which keep algae in-check on the reefs.
It has red or orange antennae, lacks hair, and its claws seem rough or grainy. This hermit crab will pick a shell it can pull its entire body back into. I saw both P. hirsutiusculus and P. granosimanus in the same tidepool at Rosario recently. A third species to watch for is Pagurus beringanus. This species is usually subtidal but may occasionally be seen in very low subtidal areas.
Unlike the UK, some of Florida’s resident snakes are venomous to humans, here’s the deadly list; Copperhead, Cottonmouth, Rattlesnake, Timber Rattlesnake, Dusky Pigmy Rattler and the yellow striped Coral Snake. Rest assured, it’s very doubtful you’ll see any of these poisonous reptiles unless you visit Central Florida Zoo in
• Fish: The Rideau River has a variety of cool-water fish. Sunfish are the most predominate but there is also a wealth of minnows, pike, catfish and other bottom feeders. The rarest species of fish in the Rideau River are the mottled sculpin and emerald shiner. • Native Mussels: Mussels are an important part of the Rideau Rivers ecosystem by filtering around 8 gallons of water in a single day. They accomplish this by feeding on algae and bacteria.
Their narrow pointed teeth are ideal for holding prey, most of which is swallowed whole. Tests on the feeding habits of angel sharks have shown that they react to any passing prey, spitting out anything that does not appeal to their appetite. They have complete faith in their camouflage when approached by divers but will inflict a shallow bite if harassed. The various species of Angel sharks range in size up to 6.5 feet (2 m) long and are mostly bottom dwellers that live on ocean floors of depths from 10 to 4,300 feet (3 to 1300 m). They sometimes prefer however, sandy near shore habitats.
Other researchers think some people were trying to breed Snakeheads as they bring a large amount of money in some areas. (Frankenfish.com). The Northern Snakehead is a major predator, as it has no enemies. It has the ability to wipe out populations of native fish. “Frankenfish” entire diet mostly contains other fish, as well as plants and insects.
While I was doing research, I identified the species I found. The primary producers were Nori Seaweed, Black Pine, and Coral Weed. The sessile consumers consisted of Mussels, Acorn Barnacles, and Goose Neck Barnacles. The mobile consumers happen to be Whelks, Chiton, Starfish, and Green Crabs and they
(Eksp Klin Farmakol) According to The Scientific Method II (C.Gervasi-2010), as a crustacean, the daphnia is closely related to freshwater and brine shrimp, and more distantly related to a crab and lobster. The common name “water flea” comes from the jerky movement which they move through the water and their overall body shape. The daphnia’s bodies are almost transparent and with a microscope, the heart beating
