The ocean consists of plentiful colorful coral reefs.

One just has to look at the number of people and areas involved in the coral triangle (e.g.

Seagrass lives in the back reefs to absorb sediments from the coral.

The delicately balanced marine environment of the coral reef relies on the interaction of hard and soft corals, sponges, anemones, snails, rays, crabs, lobsters, turtles, dolphins and other sea life....

Or would "coral reef free-for-all" be better,

It is also noteworthy that many "terrestrial plant lights" as well as many aquarium plant lights (often of lower in kelvin temperature) have more "red nanometer spikes" than higher kelvin 6500k, 10,000k & higher lamps.
The problem with these lights is that while all plants utilizing photosynthesis require the same essential ABCs of PAR (see the PAR section), the facts of light energy penetrating water requires higher kelvin (6500k +) be added to provide maximum PUR (see Useful light energy/PUR section). Aquatic Plants and corals have adapted/evolved to the natural light energy at certain depth of water and the misguided attempt to adapt these terrestrial plant lights is not going to be 100% effective as a light with more water penetrating blue & slightly lower red nm energy.

It will focus on the impact of increasing ocean temperatures on coral reefs.

All things considered, those natural guidelines leave a fairly wide range of acceptable temperatures. I keep my aquarium at about 80-81° F year-round. I am actually more inclined to keep the aquarium cooler in the summer, when a power failure would most likely warm the aquarium, and higher in winter, when a power failure would most likely cool it.

Over 2500 species of coral have been identified 1000 of which are reef building hard coral....

Lord of the Flies is an imitation of The Coral Island.

In fact these lamps are even a good choice for many aquariums such as 60 gallons and larger since each fixture can be linked together forming a larger fixture.
For instance I have used two T2s linked together for some 60 gallon FW aquarium and two sets of two (placed in parallel in the hood) for planted 60 gallon FW aquariums.
T2 Fixtures/lights also work well in Marine Aquariums (particularly pico/nano reef & Refugiums) since these lamps in the 6400 K version have a high output in PAR required for symbiotic algae that live within corals. As well actinic/blue versions of the T2 light are now available to the consumer.

My passion lies with the “Rainforests of the Sea”, the coral reefs.

I should also note that as of my latest update of this section (VHO), I have found their durability in relation to cost, and output in essential lighting parameters is not as good as T2, T5, SHO or especially LED Lights, which the LED in my tests, feedback, research and experience are the future of aquarium lighting, especially as it pertains to freshwater plant and reef aquariums.

They are old, eroded volcanoes, fringed by a coral reef.

Another major advance happened in the late 20th century: the ability to analyze DNA. was discovered in 1953. In 1973, . In 2003, . was accomplished in 2005, for orangutans in 2011, and for in 2012. The comparisons of human and great ape DNA have yielded many insights, but the science of DNA analysis is still young. What has yielded far more immediately relevant information has been studying human DNA. The have been identified. Hundreds of falsely convicted Americans have been released from prison, and nearly 20 from , due to Human DNA testing has provided startling insights into humanity's past. For instance, in Europe it appears that after the ice sheets receded 16,000 to 13,000 years ago, , and for all the bloody history of Europe over the millennia since then, there have not really been mass population replacements in Europe by invasion, migration, genocide, and the like. Europeans just endlessly fought each other and honed the talents that helped them conquer humanity. There were , but other than hunter-gatherers being displaced or absorbed by the more numerous agriculturalists, there do not appear to be many population replacements. In 2010, suggested that male farmers from the Fertile Crescent founded the paternal line for most European men as they mated with the local women. DNA testing has demonstrated that all of today’s humans are , of whom a few hundred and conquered Earth. The , as well as genomes of other extinct species, and for a brief, exuberant moment, some scientists thought that , -style. Although dinosaur DNA is unrecoverable, organic dinosaur remains been recovered, and even some proteins have been sequenced, which probably no scientist believed possible in the 1980s.

Initially, corals formed fringing reefs around volcanic islands.


The newest generation T2 Lights require less watts to provide the same useful light energy (in particular required by plants & coral) than all other lights except for LED.
Speaking of LED Lights, the T2 makes an excellent compliment to LED Lights (for cost savings as well).
