What kind of creature is a Cachalot?
Sperm Whale (Cachalot) (Physeter macrocephalus)
How are sperm whale classified?
Taxonomy. The sperm whale belongs to the order Cetartiodactyla, the order containing all cetaceans and even-toed ungulates. It is a member of the unranked clade Cetacea, with all the whales, dolphins, and porpoises, and further classified into Odontoceti, containing all the toothed whales and dolphins.
What phylum are sperm whale in?
ChordateSperm whale / PhylumA chordate is an animal of the phylum Chordata. All chordates possess five synapomorphies, or primary characteristics, at some point during their larval or adulthood stages that distinguish them from all other taxa. Wikipedia
Why is a sperm whale called a Cachalot?
The head of the sperm whale contains an enormous fluid-filled organ (which whalers called the case). During whale harvests, this organ, now called the spermaceti organ, was discovered to contain a white liquid that whalers mistook for the sperm of the whale.
Where do Cachalot whales live?
oceans
Habitat and Distribution. Sperm whales live in oceans around the world. They prefer ice-free water that is over 3300 feet deep but will venture close to shore. Only males frequent the polar regions.
Which animal has the biggest sperm?
Drosophila bifurca
Drosophila bifurca is a species of fruit fly. Males of this species are known to have the longest sperm cells of any organism on Earth—an impressive 5.8 cm long when uncoiled, over twenty times the entire body length of the male.
What is the scientific name of whale?
CetaceaCetaceans / Scientific name
What is ambergris used for?
ambergris, a solid waxy substance originating in the intestine of the sperm whale (Physeter catodon). In Eastern cultures ambergris is used for medicines and potions and as a spice; in the West it was used to stabilize the scent of fine perfumes.
What is spermaceti used for?
spermaceti, a wax, liquid at body temperature, obtained from the head of a sperm whale or bottlenose whale. Spermaceti was used chiefly in ointments, cosmetic creams, fine wax candles, pomades, and textile finishing; later it was used for industrial lubricants.
What is ambergris made of?
It is a product of the sperm whale, as only sperm whales make the compound responsible for ambergris’ allure: ambrein. Different organisms biosynthesise different compounds, such as caffeine made by cocoa, coffee or tea plants. Ambrein is made by sperm whales only to glue together squid beaks.
Who has the smallest sperm?
Sperm is the male reproductive cell. Smallest sperm is found in crocodiles and Amphioxus (. 02 mm).
Why is it called ambergris?
Because it was picked up as drift along the shores of the North Sea, ambergris was likened to the amber of the same region, and its name is derived from the French words for “gray amber.” Fresh ambergris is black and soft and has a disagreeable odour.
How ambergris is formed?
It is produced by sperm whales and has been used for centuries, but for many years its origin remained a mystery. Ambergris has been a unique phenomenon for millennia. Fossilised evidence of the substance dates back 1.75 million years, and it is likely that humans have been using it for more than 1,000 years.
What kind of lipid is spermaceti?
The lipid structure of the spermaceti organ of the sperm whale (Physeter catodon) has been investigated in an attempt to clarify its possible function. The major lipid classes present were wax ester and triglyceride, and their fatty acid compositions have been determined by gas-liquid chromatography.
What is synthetic spermaceti?
Spermaceti Wax is waxy liquid harvested from Whales, and when the industry realized that there was a demand for a more friendly approach they created the synthetic alternative, Cetyl Esters Wax, which is produced from coconut.
How do you identify ambergris?
One test for ambergris is to poke it with a hot needle and a liquid should ooze out – try the “hot needle test” with a candle at home. But many waxy objects melt when exposed to heat. As for the white smoke, most objects immersed in water take on some of it.
What are the aspects of bacterial classification?
Some of the aspects of bacterial classification also help in the identification of bacteria. The cell wall is a characteristic plant cell. Bacterial cell wall feature has features useful for classification. You may also like the Differences between Bacterial cell and Human cell. Staining: Cell wall of bacteria differs based on the layers in it.
How are bacteria classified based on the temperature they can survive?
This is quite an interesting method as they are differentiated based on their preference for the surrounding temperature. Bacteria can grow at cold temperatures and even hot temperatures besides normal room temperatures. So, they are classified based on the temperature they can survive it. Like
How do you classify bacteria based on the number of flagella?
Classification of Bacteria on the Basis of Number of Flagella. On the basis of flagella the bacteria can be classified as: Atrichos: – These bacteria has no flagella. Example: Corynebacterium diptherae. Monotrichous: – One flagellum is attached to one end of the bacteria cell. Example: – Vibro cholerae.
What is the classification of bacteria on the basis of osmotic pressure?
Classification of Bacteria on the Basis of Osmotic Pressure Requirement . Halophiles: Require moderate to large salt concentrations. Cell membrane of halophilic bacteria is made up of glycoprotein with high content of negatively charged glutamic acid and aspartic acids. So high concentration of Na+ ion concentration is required to shield the
