What is the biggest supercluster? The biggest supercluster known in the universe is the Hercules-Corona Borealis Great Wall. It was first reported in 2013 and has been studied several times. It’s so big that light takes about 10 billion years to move across the structure.

14 of the smallest animals on Earth

• The Etruscan shrew is about 1.5 inches long on average.
• The Kitti’s hog-nosed bat is the world’s smallest mammal at 1.1 inches.
• A Brookesia micra grows to be only 1 inch long.
• The Virgin Island dwarf sphaero can be a mere 0.6 inches.
• The Monte Iberia eleuth is a tiny frog that grows to be 0.4 inches.

shrews

The smallest mammal in the world is the bumblebee bat (Craseonycteris thonglongyai), weighing in at just barely 2 grams and measuring 1 to 1.3 inches in length, about the size of a large bumblebee.

Octopuses or octopi (both are technically correct) are one of the most well-known animals with multiple hearts.

Vaquita

All eight species are protected under national and international law.

• RHINOCEROS. Rhinos are large herbivorous mammals.
• TIGER. Tigers are considered as one of the world’s most threatened animal species.
• VAQUITA. Vaquita, the world’s rarest marine mammal, is on the edge of extinction.
• SUMATRAN ELEPHANT.
• ORANGUTAN.

The survival of the marine mammal – the vaquita marina – a porpoise endemic to Mexico’s Gulf of California, remains precarious. Perhaps ten or less of the individuals in the species are still alive, after one died in a fishing net in March 2020. But they exist!

• Species that went extinct in 2020.
• Splendid poison frog.
• Jalpa false brook salamander.
• Simeulue Hill myna.
• Lost shark.
• Smooth handfish.
• Lake Lanao freshwater fish.
• Chiriqui harlequin frog.

Dodo DNA is quite rare because DNA decays easy in warm climates and since the dodo was endemic to tropical Mauritius almost all bones found there do not contain viable DNA. However because the Dodo was brought to the more temperate Europe, scientists were able to sequencing Dodo DNA using bones stored in Copenhagen.

15 Animals That Will Be Extinct By 2050 If We Don’t Help

• Orangutans. Orangutans play an important role in their environment by feasting on fruit and spreading out the seeds around the ecosystem.
• Lemurs. Lemurs have been around for 70 million years, making them the longest living mammals on the planet.
• Hawksbill turtle.
• Rhinos.
• Polar bears.
• Gorillas.
• Vaquitas.
• Cheetahs.

There are multiple theories around what might ultimately cause human extinction — everything from alien invasions to catastrophic asteroid strikes. But among those investigating this question, there’s a general consensus that some risks to human life are more plausible than others.

The earliest life forms we know of were microscopic organisms (microbes) that left signals of their presence in rocks about 3.7 billion years old. The signals consisted of a type of carbon molecule that is produced by living things.

Bacteria have been the very first organisms to live on Earth. They made their appearance 3 billion years ago in the waters of the first oceans.
