Arthropod

15. The blanket octopus is not your ordinary octopus, they contain long webs connecting to their body. The females can grow as large as six feet while the males are only 5 centimeters in length. With the weight ratio to at least 10,000 to one, it sounds like mating should be fun. When the male finds a female octopus, he breaks off one of his arms and crawls inside her to store sperm, then swims off to die. Actually, that doesn’t sound very fun at all, but at least he got a happy ending, right?…

juvenile arthritis and rashes on their body. Transferred through the bite of an infected tick, the infection can spread through the joints, the bloodstream, the heart, and the nervous system if not properly treated. Lyme Disease is the most common arthropod-borne illness in North America, with there being over 200,000 cases each year, but its diagnosis and treatment can be challenging for clinicians to identify because of its diverse manifestations. Therefore, it is imperative…

During the different stages of decomposition, feeding on the dead body can take place by host killers (predators) that includes birds, insects, microorganisms and other arthropods causing considerable damage to the both soft and hard tissue. The vast knowledge about scavenging, allowing the forensic experts to analyze the succession of insects and effect of scavenging on decomposition (O’Brien et al., 194-199). Most of the previous studies were focused on the mammalian scavengers, while the…

All animals belong to the supergroup Unikonta. Since these animals are found in almost every environment on earth, it has become possible to study their characteristics and construct evolutionary relationships, noting morphological and molecular similarities and differences. The relationships between the most primitive of animals were determined by the morphological traits of symmetry, tissues, body cavity, embryological development, and molecular evidence. [1] Symmetry and tissues are major…

In the past few centuries Earth’s climate has change dramatically with the increase of greenhouse gasses, and changes in global temperature. Global climate change has become a world wide spread issue. The international panel for climate change says global climate change is the result of the anthropogenic increases of carbon dioxide, and other greenhouse gases. “Soil biological processes have major long-term effects on composition of Earth’s atmosphere, which in turn influences all living things,…

which has a thicker and wider beak respectively. These differences are due to their contrasting diets, for example the Certhidea Olivacea’s beak allows for a diet of small insects while the Geospiza Magnirostris’ beak allows for a diet of grains, arthropods, fruits and seeds that other finches are unable to consume as they are big and…

Microbial contamination is a constant problem, which often compromise development of all in vitro techniques. Therefor cleanliness and proper care of equipment are vital to the operation of a tissue culture laboratory to avoid the risk of contamination. In this practical, the main objective was to observe the sources of contamination and to learn maintenance techniques which are relevant to avoid the risk of contamination in the laboratory premises. While observing the cultures,…

Virus Taxonomy Order: Unassigned Family: Bunyaviridae Genus: Phlebovirus Species: Toscana virus talk.ictvonline.org Structure and genome The toscana virus (TOSV) is a negative-single stranded RNA virus, it is spherical in shape, it has an enveloped surrounding its capsid, and it has a diameter of 80–120 nm. Its genome is partitioned into three segments, termed (large)L, (medium)M and (small)S. With L about 6,400 nucleotides in length, M about 4,200 nucleotides in…

The cane toad reproductive system especially of male consists of the fat bodies and this cannot be found in a reproductive system of a common brushtail possum. The process of how sperm travels is also different between the two animals. In a common brushtail possum, the sperm travels through the vasa deferentia, which transports the sperm from the epididymis to the urethra (Venugopal, 2016. pg 3.5). While in a cane toad the vasa efferentia helps carry the sperm from the testes to the kidney and…

months. The lifespan of these frog can be up to 17 years. These frogs are arboreal, saltatorial, diurnal, motile, sedentary, solitary, as well as territorial (mostly the male Dendrobates). Dendrobates are carnivores (insectivores) that eat small arthropods. Their communication and perception channels use visual, tactile, and acoustic to communicate. D. pumilio are found to survive for up to 17 years ("Arrow-poison Frogs", 1970; Penner 2011,…
