Question
Spring 2018 Research and describe the basic classification of the 2 animals you dissected in this lab (squid & earthworm) from about the rank of Genus, Family or Order up to the rank of Kingdom. At each level of the classification, characterize the organisms included and give a good example. At what levels of the classifications are there members that occur in Ohio and what are they? We can illustrate what you are being asked to do using the familiar coyote, as follows The coyote, Canis latrans, is in the Genus Canis. Other members of this Genus include the wolf, various als, etc. The coyote is found in Ohio today, having spread here about 35 years ago from its native range in the west. The grey wolf occurred in Ohio before European colonization but has been wiped out here by predator-control programs The Genus Canis is in the Family Canidae. Other members of the Family include foxes, such as the Red Fox and Grey Fox and many other kinds of foxes. The red fox and the grey fox occur in Ohio. The Family Canidae is in the Order Carnivora. Other members of the Order Carnivora include cats, bears, weasels, and seals. Ohio has, or has had, several carnivores. The bobcat occurs in Ohio but was wiped out by the mid 1800s. It has been making a recovery from near extinction here under conservation efforts. The cougar is native to Ohio but also was wiped out here during European colonization. Very rare dispersing individuals from western populations have turned up as far east as Chicago, but there have not been any confirmed sightins in Ohio. The black bear is native to Ohio but also was extirpated by the 1850s. It too is returning to Ohio from western Pennsylvania & West Virginia. The grizzly bear occurred here in post-glacial time but its range had contracted to the west & north by the time of European colonization. Etc. This process would be continued up to the level of Kingdom. The coyote example begins at the species level which you probably will not be able to do with the earthworm and the squid. You may have to start at the rank (level) of genus, depending on the information you are able to locateExplanation / Answer
Squids have differentiated from molluscs in ways where their body structure has condensed antero-posteriorly where as it has extended dorso-ventralily. The foot, as observed in their ancestors (molluscs) has modified into tentacles with highly developed sense organs, example - extremely powerful eye-sight, like those of vertebrates. Their ancestral shell was lost in evolutions with only an internal gladius as the remaining proof. The gladius gives support to the squid's mantle and is the sight where muscle attaches. It is made up of a material similar to chitin.
The squid belongs to the order Teuthida.
They are members of the class cephalopoda, its other members include octupus and nautilus. these marine animals have bilateral symmetry, head, tentacles instead of arms. they are often referred to as inkfish because of their ability to squirt ink.
They belong to the phylum mollusca - which largely consistes of invertebrates. It is the biggest marine phyllum, consisting of almost 23% of named organisms. their natural habitat is freshwater or terrestrial habitat. they show immense diversity not just in their behaviours and habitat, but also in their shape, size and anatomical features. This phylum has around 10 classes of which 2 are extinct. The most common feature observed in all molluscs are a mantle, a radula, and the stucture of the nervous system.
Their kingdom is Animalia.
The earthworm is tube shaped, and more commonly found in the soil, surviving by feeding on dead organic matter.It respires through the skin and its digestive system is founf running across the length of the body. It contains both central and peripheral newvous system. Most earthworms are hermaphrodites, i.e. contain both male and female reproductive organs.
They belong to the order Megadrilacea.
Their class is Oligochaeta. Most organisms in this class are aquatic and terrestrial worms.
They make up half of the phylum Annelida. Annelids are also called segmented or ringed worms. most species in this phylum have adapted to different ecologies (marine, fresh water, terrestrial). Annelids are bilateral, invertebrates, triploblastic and symmetrical organisms, and use parapodia for movement.
