The pigment luciferin is responsible for the bioluminescence of fireflies.
This pigment is oxidized by a certain enzyme, resulting in the release of excess energy in the form of light.
The efficiency of this light radiation in fireflies is extremely high and ranges from 87% to 98%. For comparison, in an incandescent lamp, only 5% of the energy goes into the light, the rest goes into heat.

Here we see the African marabou Leptoptilos crumeniferus. These birds have a memorable appearance, but prosaically they often live near large landfills, where they look for food, and a bare neck and head without feathers helps to keep their bodies clean.
The African marabou reaches a height of more than one and a half meters and weighs 8.5-10 kg.
There is a peculiar sac in the neck area that connects to the nostrils. It can inflate and reach 40 cm in diameter. In young individuals, it is practically absent, its growth occurs during the growth of the bird. Previously, it was believed that birds put food in it in reserve, but it turned out that this outgrowth is used only during mating games and so that the bird can put its head on it at rest.

The cassowary Casuarius casuarius looks completely harmless, but it is original and "elegant" - but sensing a threat (or just seeing a person on the territory of its possessions), this flightless inhabitant of the rainforests of New Guinea and northeastern Australia immediately attacks.
The main weapon of this bird is huge legs and powerful long claws. Cassowaries can reach speeds of up to 50 km / h, so a person cannot hide from such an enemy. It is man who is the only potential enemy of cassowaries.
It is worth noting that under normal conditions these birds prefer to eat fruits, mushrooms, snails, insects, frogs, snakes and other small animals. Nevertheless, in 2004, the cassowary was included in the Guinness Book of Records as the most dangerous bird on Earth.
