ANALYSIS QUESTIONS
As you dissect either virtual or real specimens, you will need to examine the body shape and coloration of each of your mollusks.
You need to be specific in the analysis questions – about shell (inner/outer), camouflage/coloration, mobility, body shape, fins. Make sure to discuss about both the organisms in the questions.
SQUID ANALYSIS QUESTIONS:
How is each animal adapted to the environment?
What type of habitat or environment and lifestyle is each animal adapted for?
What problems will these animals have?
What features observed will enhance its chances for survival?
OYSTER & SQUID ANALYSIS QUESTIONS:
How is each animal adapted to the environment?
⦁ Squid: Squid have some unique adaptations. Some can change color, some use bioluminescence to create light, and some shoot ink to cloud the water and lose predators, they also have many other adaptions like the shape body, there long and skinny making them fast …show more content…

⦁ Squid: It depends on the species you are talking about, you can find squid in all major bodeis of water. Some will live in warm tropical waters and other will live in a cooler climate water. Most squid live in salt water but there are some that live in freshwater as well.
⦁ Oysters: They can live in a wide range of areas due to there strenght towards temperature, salinity, and concentrations of suspended sediments and dissolved oxygen.
What problems will these animals have?
⦁ Squid: Most squid have very short life spans, also squid a prey for a wide varity of larger animals and their only defense is there speed and ink (sephia).
⦁ Oyster: Their only defense is there shells due to the fact that they don 't move. There considred a key species because their the pray for a wide majority of animals.
What features observed will enhance its chances for survival?
⦁ Squid: Some can change color, some use bioluminescence to create light, and some shoot ink to cloud the water and lose predators, all these adaptaions will enhance their chance of survivale.
⦁ Oysters: Their shell, and camoflouge, will enhance their chance of

  • Bluegill Fish Experiment Lab Report

    739 Words  | 3 Pages

    The experiment consisted of two sub-experiments that when synthesized together, successfully answered our main question. The first of the two sub-experiments focused on collecting data for the creation of a life table in which Daphnia magna were not in the presence of a predator such as Lepomis macrochirus, known in laymen’s terms as bluegill fish. The second of the two sub-experiments focused on collecting data for the creation of a life table as well, but this time the daphnia were subjected to an environment where bluegill fish were present. The collection of the data for the creation of the first lifetable without predation consisted of fourteen replicates or daphnia starting at age 3 and ending at varying ages depending on the mortality of each replicate group.

  • Hastings Point Lab Report

    1610 Words  | 7 Pages

    70 common limpets were identified in the 40m bracket identified as the littoral zone, between 0m to 40m. The common limpet employs a range of adaptations to survive the abiotic and biotic conditions associated with the littoral zone. Firstly, the limpet uses a structural adaptation to overcome the harsh wave action in the tidal zone, by using their radula to grip on to imperfections in the rock. Furthermore, they employ a behavioural adaptation of grinding their shells down into the rock, to further ensure they are not swept away by the tide. Additionally, the limpet utilises a behavioural adaptation regarding its tough shell and powerful radula, to defend against predators.

    The Striped Pyjama Squid The striped pyjama squid is a very poisonous cephalopods out of the few that wander across the ocean bottom of indo- Pacific Oceans. Lots of scientists think that the black stripes on the Pyjama squid gives away its venomous attributes eliminating many predators. Also when they turn a dark purple with black stripes it give away its venomous attributes. Even though the name says squid ,The Striped Pyjama Squid is actually a species of cuttlefish, a multifaceted animal that can often change its appearance, has an central shell, eight arms and two feeding tentacles.

  • Environmental Conditions Of Brine Shrimps

    232 Words  | 1 Pages

    Brine Shrimps tend to hatch in specific environmental conditions, such as high and low salt concentrations in water, weather and temperature. As one of the environmental conditions in which Brine Shrimp eggs hatch is water salinity and so, in this assignment, we were given 4 different salinity levels of water, which were 0%, 3%, 6% and 9%. As a result of the experiment, we noted that after 24 hours only one egg hatched at 3% salinity level and none at 0%, 6% and 9% levels. The second day, which was after 48 hours, there were 0 shrimps that hatched in 0% and 9% salinity levels, whereas at 3%, 7 out of 46(15.3%) eggs hatched and 6 out of 49(11%) at 6% levels. Based on this data our group concluded that the best level for hatching shrimps is 3%

  • The Daphnia Magna Experiment

    388 Words  | 2 Pages

    This laboratory experiment involving invertebrates is conducted to enable students to investigate Daphnia magna’s responses to external stimuli, therefore developing a better understanding and knowledge of homeostasis that occurs in organisms and the reaction and behavior exhibited by the daphnia magna when varying conditions are exposed to the organism compared to its natural environment conditions (Carter-Edwards et al, 2011). In order to understand the experiment, a foundation of information about the chosen organism such as its natural environment and physiology must be understood. According to Clare (2002) and Ebert (2005), Daphnia magna are small planktonic crustaceans belonging to the subclass Phyllopoda, found in lakes and

    The adaptive features of animals: i. Adaptation to live in the habitat lack of oxygen A. Crayfish: Crayfish lives in fresh water stream, which is an aquatic environment. The oxygen level in fresh water upper stream is higher than the lower stream, but the oxygen concentration is still low. The gills of crayfish are much bigger than the size at first glance. They occupied under the cephalothorax carapace in branched-shape and provided a large surface area to volume ratio to carry out gas exchange. Fresh water will be pulled into the cavity by the movement of the “gill bailers”.

  • Which Water Will Brine Shrimp Prove The Best In With The Egg

    999 Words  | 4 Pages

    The brine shrimp have cousins just like us, the brine shrimp cousins are the lobster and the crab. The brine shrimps subclass Branchiopoda meaning “gill foot,” is referring to the fact that the gills are on the outer side of the limb bases. The brine shrimp glide through the water, it’s propelled by what looks like two wings along their sides.. Under the microscope, the “wings” are revealed to be of 11 pairs of appendages that undulate and that act as paddles. The Artemia Salina is in the order Anostraca, which means “no shell.”

    It is strongly recommended to avoid those activation to protect stream environment for eel natural habitat.(17) Thus, in light of the results in this study, it can be assumed that excavation and habitat destruction observed in recent years has probably reduced the quantity and quality of suitable habitats for juvenile eel, which could be negatively affecting both ecologically and economically. 4.5 Further studies Various observations European eel life history should be describe not as truly catadromous, but "facultative or semi catadromous". Due to fact that European eel were found in different waters such as freshwater,brakish and coastal,and freshwater phase is not be a essential part of their life history, could not make them not truly catadromous species.(18) This is the only experimental study until now, as far as we know, that contribute to the understanding the habitat choice of eel juveniles in brackish salinity water .Therefore

  • Arthropods Vs Molluscs Essay

    940 Words  | 4 Pages

    Arthropods and Molluscs, although both common in harsh coastal environments, in fact do not share many similarities due to the differences in their adaptations to their environments. Arthropods are described as segmented coelomates that have jointed appendages whereas Molluscs are coelomates, but have neither segmented bodies nor jointed appendages. By animal classification, both Arthropods and Molluscs have bilateral symmetry, are tripoblastic (having three layers of tissues in tissue development – ectoderm, endoderm and mesoderm) and have protosome pattern of development. Arthropods eventually branches away from Molluscs due to ecdysis, as they subsequently develop the ability to undergo molting, which Molluscs cannot.
