The Seven Classification Levels
Classification is the foundation of a various leveled arrangement of classifications based on assumed regular connections among living things. The study of natural characterization is regularly called scientific classification. Classification in biology is the logical investigation of naming, characterizing and ordering living things into groups with common characteristics. The main classification hierarchy include; kingdom, phylum, class, order, family, genus and species. In this study, the animals studied include Lion, rats, gigs, Grass frog, Perch and Pigeon.
The five animals are classified into the seven classification levels as shown below;
|
Lion |
Rat |
Pig |
Grass frog |
Perch |
Pigeon |
|
Kingdom: Animalia Phylum: Chordata Class: Mammalia Order: Carnivora Family: Felidae Genus: Panthera Species: Panthera leo |
Kingdom: Animalia Phylum: Chordata Class: Mammalia Order: Rodentia Family: Genus: Rattus Species: Rattus rattus |
Kingdom: Animalia Phylum: Chordata Class: Mammalia Order: Artiodactyla Family: Suidae Genus: Sus Species : Sus ahoenobarbus |
Kingdom: Animalia ; Phylum: Chordata ; Class: Amphibia ; Order: Anura ; Family: Limnodynastidae. Species: L. tasmaniensis |
Kingdom: Animalia ; Phylum: Chordata ; Class: Actinopterygii ; Order: Perciformes. Family: Percidae Genus: Perca P. flavescens |
Kingdom: Animalia Phylum: Chordata Class: Aves Order: Columbiformes ; Family: Columbidae ; Genus: Columba ; Species: C. livia. |
Lion (Panthera leo), huge, intensely constructed feline that is second in size just to the tiger. Lions are generally dynamic around evening time and live in an assortment of environments yet lean toward meadow, savanna, thick clean and open forest. Lions live in an assortment of territories however incline toward field, savanna, thick clean, and open forest. By and large, they lived across a lot of Europe, Asia, and Africa, however presently they are mostly found in pieces of Africa south of the Sahara.
Rodents are flimsy followed, medium-size rodents that started in Asia and Australia however are currently viewed as from one side of the planet to the other. “Genuine rodents” are individuals from the variety Rattus, however other rat genera are likewise alluded to as rodents and offer a significant number of similar attributes. Rodents separate from mice by being bigger, with longer, more slender bodies and long legs. Rodents are seen as from one side of the planet to the other. For instance, the rice-field rodent is found in Southeast Asia, the Australian bog rodent is found in Eastern Australia, and the Norway rodent, likewise called earthy colored rodents, is viewed as on each mainland of the world with the exception of Antarctica, as per the Animal Diversity Web at the University of Michigan.
Grass frog is the littlest frog in North America going in size from 11-19 mm (7/16 to 3/4 in). Its dorsal tinge goes from dark to brown to ruddy. A trademark dull stripe stretches out from nostril through the eye onto the sides. A dull middorsal stripe is some of the time present. The ventral hue is yellowish or white. The toes are somewhat webbed. This species is in some cases mistook for youthful Brimley’s tune frogs. The littlest is the little grass frog (Pseudacris, or Limnoaedus, ocularis), which doesn’t surpass 1.75 cm (0.69 inch) long and is found in cypress swamps in the United States from Virginia to Florida and Alabama. Nonhylid tree frogs incorporate individuals from the families Centrolenidae
The pig, frequently called pig, hoard, or homegrown pig while recognizing from different individuals from the family Sus, is an omnivorous, trained, even-toed, hoofed warm blooded animal. It is differently viewed as a subspecies of Sus scrofa or an unmistakable animal type. The homegrown pigeon (Columba livia domestica) is a pigeon subspecies that was gotten from the stone bird (likewise called the stone pigeon). The stone pigeon is the world’s most established trained bird.
A dissection was done to examine the internal organs of the animals studied in this practical. The tools used in dissecting the animals in the lab were Scissors, pins, scalpels, needles, forceps, dissection tray and dissecting probes. The major anatomical systems were observed after the dissection. The safety measures during the dissection were putting on gloves and laboratory coats.

Integument |
consists of the skin, the feathers and the appendages |
involves the skin, hair, skin organs, hooves, paws, computerized cushions, horns and quills |
Different layers: Epidermis and dermis, subcutaneous fat tissue, nerves, muscle structure and vessels are mesodermal beginning |
Perch integument is an enormous organ that is nonstop with the coating of all the body openings, and furthermore covers the balances |
as a layer corneum that contains α – keratin |

|
Digestive |
It includes mouth, buccal pit, pharynx, throat, stomach, small digestive system and internal organ which opens to the outside by cloacal gap. |
Non-ruminant |
Similar to human but the system lacks gull bladder and has bigger cecum |
incorporate the mouth, teeth and gill rakers, throat, stomach, pylorus, pyloric caeca, pancreatic tissue (exocrine and endocrine), liver, nerve bladder, digestive tract and rear-end. |
The stomach related arrangement of a frog forms a mouth, pharynx, throat, stomach, small digestive tract, internal organ, and cloaca. . |
|
Respiratory |
Comprises of outside nostrils, glottis, larynx, windpipe, bronchus and lungs.. |
The upper respiratory parcel includes the nasal pit and the nasopharynx. The lower respiratory starts with the larynx and goes on into the chest as the windpipe, bronchi, bronchioles and lungs. |
Obligate nasal breathers. |
Gills, mouth and operculum |
the skin, lungs and lining of the mouth |
|
Urinary |
two kidneys and two ureters |
ureter, kidneys, urinary bladder, urethra, umbilical cord, unogenital cord |
Two kidneys, ureters, an urinary bladder and an urethra. |
Urinary pore and abdominal pore |
Kidney |
|
Nervous |
Cranial nerves from the oblangata |
Autonomic nervous system |
Rat |
Perch has a brain in the skull |
brain, a spinal cord, and nerves |
|
Reproduction |
Monogamous |
female reproduction is dorsal to the digestion tracts in the pelvic cavity. Male- testes, the epidiymes, the ampullae and the seminal vesicles |
Fertilization of ova happens inside the female, and the prepared zygotes create in the mother during a growth period known as pregnancy. |
an egg comes from a female and is prepared by male sperm. |
External fertilization |
The feta forms of the animals differ in terms of how their structures are formed and functioning. As they develop into maturity, the adult forms anatomical features become mature and they are then able to survive their respective environments. The fetal forms live in environments that favor their immature nature and develop with time.
The animals are closely related since they are from the same Kingdom (Animalia), Phylum (chordata), class (Mammalia, aves, anura). They differ from classes down to species due to difference in some features. The most common ancestor for the animals can be traced at the phylum level since they all belong to the same phylum.
