Just like humans, animals also have many special actions and abilities that are difficult to understand depending on their species and personalities.
Obviously, the Earth is a diverse ecosystem and it is not easy to understand all the animals in nature. There are some animals on this Earth that have quite strange habits in treating their own species, mates or children.
Turtles mainly use their eyes to search for food and shelter. Therefore, they are often attracted to bright colors such as red, orange, and yellow. When they find food with many different colors, they will eat the ones with their favorite colors first.
Some animals also commit suicide like humans when they feel bored and don’t want to continue living. Many documents show that animals have a fairly high mortality rate and often occur in herds. In the 1800s, people witnessed a series of animals jumping off cliffs.
A bridge in Scotland became a suicide site for dogs or a phenomenon of mass bird deaths in India.
Animal suicide does not seem to occur only in a few species. In November 1998, in the waters of New Zealand, squid, shrimp, and whales pulled themselves ashore and died en masse for unknown reasons.
In 2005, cows and sheep in Türkiye suddenly jumped off a cliff to commit suicide. This phenomenon has baffled many scientists. They believe that the instinct to predict natural disasters or changing climate conditions is the fundamental factor causing tragic suicides.
When monitoring images on Google Earth, many people discovered that cattle always stand along the North-South axis when grazing, their heads often facing North. Many scientists believe that this animal also has the ability to orient the Earth’s magnetic field like birds or salmon.
Dating is quite difficult, even for humans. For ferrets, this is a way for them to maintain their lives. Within 1 year, if the female ferret does not find a mate or is rejected by the other, she will die.
Flamingos use their long necks to search for crabs and snails while their heads are upside down. Scientists have conducted research by using a rope to fix the head and feeding the flamingos in a normal position. However, they cannot digest food.
6. Immortal jellyfish
The Turritopsis Nutricula jellyfish is a multicellular organism that can reverse its life cycle from adulthood back to a single-celled organism and continue to grow. In theory, this process of cell transfer occurs indefinitely, allowing them to live forever without dying.
However, the Turritopsis Nutricula jellyfish and many other jellyfish species are always facing hunting or dangerous diseases that cause them to lose their ability to transform.
7. Dolphins’ Brains Still Work While They Sleep
When a dolphin sleeps, only half of its brain rests, the other half monitors the surrounding situation and controls the activity of surfacing to breathe air to prevent drowning.
This “hemispheric sleep” also helps them avoid dangers while resting and maintain muscle movement to maintain body temperature in cold seawater.
8. Lizards spray blood from their eyes
When in danger, horned lizards often spray blood from their eyes to defend themselves. However, their blood is not poisonous, but only serves to scare enemies and find an opportunity to escape.
This activity is due to increased pressure in the sinus cavity until the blood vessels in the eyes burst, shooting at the predator. Blood from the lizard’s eyes can spray more than 2 meters away.
9. Spiders use silk to fight enemies
Tarantulas are the largest spiders in the world. They have up to 8 eyes but have very poor vision. Tarantulas often weave large webs and attach silk threads to their legs. When strangers invade their “territory”, the silk threads will vibrate and signal them to avoid and deal with them.
10. Crocodiles love to eat stones
Crocodiles are large aquatic reptiles that live across a wide area of tropical Africa, Asia, North America, South America and Oceania. Crocodiles tend to live in slow-moving rivers and lakes, and their diet is quite diverse, mainly living and dead mammals as well as fish.
Large crocodiles can be very dangerous to humans. They have extremely strong jaws and sharp teeth for tearing flesh, but they cannot open their mouths if they are tightly closed, so there are some stories of people surviving long-snouted Nile crocodiles by closing their jaws.
