Perhaps unknown to some of you, same-sex sexual behavior is not an exclusively human trait, but it has been extensively documented in non-human animals as well. Here are some animals who also show same sex behaviour:
The bonobo is an African ape closely related to humans. Studies suggest 75% of bonobo sex is nonreproductive & that nearly all bonobos are bisexual. Frans de Waal calls the species a "make love, not war" primate. He believes bonobos use sex to resolve conflicts
2) Bottlenose dolphin
These dolphins show one of the highest rates of same-sex sexual behavior documented in any animal. ♂️-♂️ mounting, genital contact & ‘goosing’ appear to strengthen alliances between small groups of males and provide practice for later opposite-sex encounter
parasitism deserves more respect as “an exceptionally successful form of life”. Animals, plants, fungi, bacteria & viruses can all be parasitic, from vampire bats to deep-sea anglerfish, whose tiny males permanently attach themselves to females.
Parasitism is a form of symbiosis—a close relationship between 2 organisms. Some parasites (parasitoids) are deadly to their hosts, many don’t cause major problems. Others will even protect their hosts from other parasites, such as viruses that shield bacteria against antibiotics
These hornets naturally occur in Asia, but humans have accidentally introduced them into North America where they pose a threat to native wildlife, as they kill other insects, like smaller wasps & bees.
1) The name murder hornet is widely used online, but it may be sensationalist, according to the Natural History Museum. These hornets don't actively hunt humans but they can kill humans with potent stings if they feel threatened, especially when people are allergic to their venom
2) Murder hornets grow up to 5,1 cm long, or about the length of a human thumb. They have yellow or orange heads that contrast with their mostly dark brown or black thoraxes — the middle section of their bodies between their heads and abdomens.
They hiss, they slither and unfortunately for humans and unsuspecting prey, they bite. Snakes bite about 5.4 million people every year, resulting in between 81,000 and 138,000 deaths
#10 Black mamba (Dendroaspis polylepis)
Africa's deadliest snake can kill a person with just 2 drops of venom. They are ~2,5 meters & are born with 2 to 3 drops of venom in each fang, so they are lethal from the get-go. Adults can store up to 20 drops in each of their fangs.
#9 Fer-de-lance
A bite from this snake can turn a person's body tissue black as it begins to die. These pit vipers, which live in Central and South America and are 1,2-2,5m long and up to 6kg, are responsible for about half of all snakebite venom poisonings in Central America.
Narwhal tusks are thought to play a role in mating, as some males have been seen crossing tusks, like fencing behavior, which may serve to display youthfulness, social status or strength among narwhals.
Narwhals can dive about 1,6 km deep in the ocean. Cracks in the sea ice above allow them to pop up for air when they need it.
Global trade is bringing invasive species to new environments around the world. Is that always a bad thing?🤔
Continue reading this thread to learn more about these species.
1) An invasive species is a type of animal, plant, fungus or any other living thing that has arrived in a new environment and can harm other species there. You might hear the term "invasive species" used interchangeably with...
2) "naturalized species," "exotic species," "noxious species" and "non-native species." Although each of these terms has a slightly different meaning, they all refer to members of a species living in an area they aren't originally from.
