Facts are supposed to provide us with a sense of
clarity and certainty. But sometimes they can be misleading too, if we just
look at them superficially. Take the case of Jupiter and Saturn, the two
largest planets in our solar system.
Let’s take Jupiter. To a superstitious person on
Jupiter the Sun would look like a blazing dot and would seem to follow two
distinctively strange elliptical orbital patterns and hence the person may
think the planet was jinxed. This is the consequence of a unique location of
the Sun-Jupiter center of mass (barycenter). The location is outside the Sun,
making them perform a loose binary dance rather than a simple planet-star
orbit.
Now consider Saturn. Its core consists mostly of
hydrogen and helium, both of which are odorless, while its atmosphere has
methane, ammonia, ammonium hydrosulfide, water vapor, phosphene, ethane,
acetylene, propane. Its upper atmosphere has ammonia clouds that would smell
like strong cleaning fluid, while deeper layers with hydrogen sulfide might
smell faintly of rotten eggs. To a human being trying to penetrate this
atmosphere, the planet would stink! But only if the human olfactory sense can
survive the journey through its clouds.
In this series of blog posts during 2026, I hope to
discuss facts that may seem strange at first glance, but which could otherwise
be explained. I will focus on one factoid every month.
The factoid for this
month is Dolphins Have Names.
Dolphins use unique "names" for each other
in the form of distinct signature whistles, which function like human names for
identification and communication, allowing them to call, recognize, and even
remember specific individuals.
This is indeed a sophisticated communication skill
unique among non-human mammals. Elephants and Parrots are also understood to
have similar capabilities.
This ability to use individually specific
vocal labels for others is considered a remarkable trait, highlighting the
advanced social intelligence of dolphins.
Each dolphin develops its own whistle, often learning
it from its mother, and other dolphins copy these whistles to address or call
out to them, like how humans use names.
Unique Whistles: Each dolphin creates a distinct whistle that serves
as its personal identifier.
Learning & Imitation: Young dolphins learn their signature whistles from
their mothers and can imitate others' whistles to call them, demonstrating
complex social learning.
Addressing Others: When a dolphin wants to get another's attention, it
mimics that specific whistle, acting as a call or "name".
Memory & Social Bonds: Dolphins remember the names (whistles) of their
close allies, using them to maintain social bonds and form teams, even
remembering cooperators from the past.
What is still not clearly known is how they avoid
having the same names – it would be silly for the bottlenecks’ bromance if
there was a single whistle for two individuals!

I always learn something new from these monthly updates! The idea of dolphins having unique names they learn from their mothers is incredibly sweet. Also, I’ll never look at 'two-factor authentication' the same way again after that last paragraph. 😂
