News: How do sperm whales talk to
each other?
What's in the news?
●
For the first time, researchers investigating sperm
whales have outlined the fundamental components of their potential
communication methods.
Sperm Whale:
●
The sperm whale, scientifically known as Physeter
macrocephalus, stands as the largest of the toothed whales.
●
Recognizable by its massive square head and narrow
lower jaw, it holds the distinction of having the largest head and brain of any
animal on Earth.
Distribution:
●
Sperm whales boast one of the most expansive global
distributions among marine mammals, inhabiting all deep oceans from the equator to the edges of the Arctic
and Antarctic pack ice.
Physical Features:
●
These magnificent creatures typically exhibit a
dark blue-gray or brownish hue, accented by white patches on their bellies.
●
Notably, they possess small paddle-like flippers
and a series of rounded humps along their backs.
Lifespan:
●
Sperm whales can live up to 60 years, making them some of the longest-living cetaceans.
Social Behavior and
Communication:
●
Highly social mammals, sperm whales communicate
with each other using a complex system of clicks known as codas.
●
Each coda serves a distinct purpose, aiding in
their social interactions and coordination.
Ambergris:
●
Ambergris, often dubbed "Floating Gold," is a rare substance extracted from the bile ducts in the intestines of sperm whales.
●
While initially light yellowish in color, it
transforms into a waxy, solid, and inflammable material.
Chemical Composition:
●
This enigmatic substance contains alkaloids, acids,
and a compound called ambrein, akin
to cholesterol.
●
Its unique composition contributes to its highly
sought-after status in the international market.
Utilization:
●
Ambergris finds its predominant use in the creation
of perfumes and fragrances.
● Possession and trade of this substance are banned in countries like the USA, Australia, and India due to conservation concerns, despite its high demand and value in certain industries.
