Corals are
sessile, which means that they permanently attach themselves to the ocean
floor, essentially "taking root" like most plants do. We certainly
cannot recognize them by their faces or other distinct body parts, as we can
most other animals. Corals actually comprise an ancient and unique partnership,
called symbiosis, that benefits both animal and plant life in the ocean. Corals
are animals, though, because they do not make their own food, as plants do.
Corals have tiny, tentacle-like arms that they use to capture their food from
the water and sweep into their inscrutable mouths.
In
troubled times, we pray to our Emperuman, Lord Devathirajan for grace – His
uthsavam concludes this day !
பவளக்கால்
நாரை என்பது பெயர்ச்சொல். ஆறு, ஏரி, கடல் முதலியவற்றின் கரைகளிலும் வயல்களிலும்
நாரைகளை நீங்கள் பார்த்திருக்கலாம். இது கொக்கு இனத்தைச் சேர்ந்தது. இவற்றில் ஒரு வகை - பூநாரை அல்லது செங்கால் நாரை
[பிளமிங்கோஸ்]. இதன் அலகு அகலமாகவும், வளைந்தும்
காணப்படும். இதன் கால்கள் நீண்டு சிவந்து இருக்கும்.
The name
"flamingo" comes from Portuguese or Spanish flamengo,
"flame-colored", these are bright red coloured. In his 1842 book, The Structure and
Distribution of Coral Reefs, Charles Darwin remarked that coral reefs were like
an "oasis in the desert" - they were flush with life despite being
surrounded by nutrient-poor seawater. This is a mystery that scientists have
continued to grapple with, ascribing the diversity of reefs to the close
relationships between the sea life within the reefs. Essentially, all food and
waste produced within reefs is rapidly taken up, leaving only a few remnants in
the seawater. However, a new study shows that tiny “cryptobenthic” reef fish –
so called because they easily camouflage with the seafloor – may help make up
the nutrient gap in coral reefs. Because
cryptobenthic fish are incredibly small and reclusive, they can be difficult to
study, so their role in ocean ecosystems is still being understood.

Today, 11th June 2020 is 10th
day of Sri Varadha Rajar Uthsavam.. it would have been ‘Sarrumurai’ purappadu in the beautiful
“Pavalakkal Vimanam” at Thiruvallikkeni.
Not sure, why this is called ‘Pavalakkal’ – pavazham is ‘coral’. There is one street in Parrys area known as
‘Pavalakkaran theru’ for traders in coral used to live and transact business
here !
Coral reefs are large
underwater structures composed of the skeletons of colonial marine
invertebrates called coral. The coral species that build reefs are known as
hermatypic, or "hard," corals because they extract calcium carbonate
from seawater to create a hard, durable exoskeleton that protects their soft,
sac-like bodies. Other species of corals that are not involved in reef building
are known as “soft” corals. These types of corals are flexible organisms often
resembling plants and trees and include species such as sea fans and sea whips,
according to the Coral Reef Alliance (CORAL), a nonprofit environmental
organization.
The world’s coral
reefs do more for the planet than provide underwater beauty. They buffer
shorelines from the effects of hurricanes. An estimated 500 million people earn
their livelihoods from the fishing stocks and tourism opportunities reefs
provide. The tiny animals that give rise to reefs are even offering hope for
new drugs to treat cancer and other diseases. Despite their importance, warming
waters, pollution, ocean acidification, overfishing, and physical destruction
are killing coral reefs around the world. Schemes to save those reefs are as
creative as they are varied; most recently, scientists released data showing
that marine protected areas can help save reefs if they are placed in just the
right spots. Genetics is also becoming a larger area of coral research, giving
scientists hope they might one day restore reefs with more heat tolerant coral.
Commonwealth
countries are to gain free access to satellite technology that will help them
monitor and protect their endangered coral reefs from threats such as climate
breakdown, overfishing and pollution. Commonwealth countries hold nearly half
of the world’s remaining tropical coral reefs, with 47 out of the 54 member
countries having a coastline. Nearly half of them are islands or groups of
islands, which face particular threats from the climate crisis, and for whom
coral reefs are often vital protections against storms as well as fish
nurseries and tourist attractions.
“Whatever we do as a
Commonwealth family will make a massive contribution to safeguarding the coral
reefs that we are dependent on globally,” said Baroness Patricia Scotland,
secretary general of the Commonwealth. “We feel this real responsibility around
the world. The Commonwealth can change the trajectory of this crisis, if our
members are willing to work together, and we will.”
Nearly all the reefs
are at risk of extinction in the coming decades as the climate crisis takes
hold, and nearly half of the world’s reefs have already been destroyed or badly
damaged in the last 30 years owing to changes in the climate, overfishing,
pollution and other exploitation. About 250 million people are directly
dependent on coral reefs for their livelihoods.
The technology will use high-resolution satellite images and data
analyses to allow marine scientists, government officials and policymakers to
monitor the health of coral reefs and take the action needed to protect them.
Software will be provided to countries free through the Commonwealth’s
partnership with Vulcan Inc, a US-based group founded by Microsoft co-founder
and philanthropist Paul Allen, and a new interactive coral reef map will be
hosted online at the Commonwealth Innovation Hub.
We are
missing Emperuman darshan, His uthsavams and purappadus – reminiscing, here are
