animal can often be unpredictable and surprise us with their unusual behaviour , but some newsworthy critters take this even further , provide scientists and the public completely regulate .
While the uncanny behaviour on this listing are a will to the complex brains of our furry , finned and ramification - tongue friends , there ’s also a dark side to some of these acts . Humans stay on to disrupt and put down the natural worldly concern in 2023 , putting many fauna under pressing and causing some to act in uncanny way . Here are 10 of the foreign animal demeanour document in 2023 .
A juvenile orca carries a large piece of a rudder after attacking a boat in the Strait of Gibraltar.
Kangaroo tries to drown dog
In October , a man get a video of a kangaroo as it try on to drown hisdog . Mick Moloney had to rescue his dog Hutchy from the Murray River in Victoria , Australia , after a manful eastern gray kangaroo ( Macropus giganteus ) held Hutchy ’s head underwater . Moloney got Hutchy to safety but take a lick from the kangaroo for his efforts .
This is n’t the first timekangaroos have behaved this way around our canine companions , and the marsupial was belike just face out for its own safety . kangaroo have learned to hop into water to defend themselves against attacks from eye tooth .
Crocodile has “virgin birth”
research worker denote the firstcrocodile"virgin parentage " in June . A female American crocodile ( Crocodylus acutus ) laid a clutch of eggs at a reptilian park in Costa Ricaafter being alone for 16 year . This soma of nonsexual reproduction had never been document in crocodiles before , although it ’s sleep together to pass in lizards , snakes , birds andsharks .
The crocodile ’s clutch bag did n’t hatch , but genetic depth psychology of a foetus within one of the egg revealed it was almost selfsame to the mother . The subject ’s authors noted that offspring digest in this way of life often suffer freakishness and do n’t pull round .
Dolphins raid crab pots
Bottlenosedolphinswere spotted steal bait from black cat in westerly Australia . The dolphins used their noses and teeth to pilfer Pisces from nets mean for crab . Wildlife conservationists filmed this behavior for the first time in 2023 , revealing the different waysdolphins learn to start the fishers ' wad .
" The most canonical edition is that the dolphinfish grabs the bait which sits on a draw or alloy oarlock inside the crab pot , " filmmaker Axel Grossmann tell Live Science in November . " So basically the dolphin pull the fish off the oarlock or break it down into comestible firearm . "
When fishers tried putting lure underneath the pots , the dolphin see to flip them over , and when they tried using sweetener boxes , the dolphins determine to open up them . Eventually , fisher and conservationist developed a dolphinfish - proof blueprint .
Kangaroos perceive pet dogs as a threat because they closely resemble dingoes, one of their native predators.
Elephant peels banana
A zooelephant teach herself to peel bananasby watching zookeepers . Pha , a female Asianelephant(Elephas maximus ) at the Berlin Zoo in Germany , rend off the stem of a banana tree , pinches the frayed skin with her trunk and uses the yield ’s weight to peel . It ’s an clever twist on the human method , which normally involves two hand and apposable thumbs .
Keepers at the zoo used to feed Pha peeled bananas when she was a calf , which is probably where she got the idea . Pha only flake off mature banana tree with brown spots . She eat gullible and icteric banana whole and rejects brown banana . When fed in a radical where her banana tree might get stolen by other hungry elephants , she skin only her last banana , presumably to bask it .
Crocodiles save dog
Three mugger crocodiles ( Crocodylus palustris ) apparently serve a young dog that had been chamfer into a river by a pack of feral dogs by nudging it to safety . The research worker who find the consequence interpret thecrocodiles ' actions as empathy . They also report that the species appear to use sticks as bait to fascinate nesting birds and is attracted to flower . However , an sovereign expert was skeptical of their findings .
" Crocodilians do have a sophisticated suite of behaviour , " said Duncan Leitch , a life scientist who specializes in the neurophysiology of reptile at the University of California , Los Angeles , told Live Science in September . " But some of these conclusions are using a human definition of intelligence and trying to get that in crocodilian reptile . "
Whale kelping goes global
Researchers first documentedhumpback whales(Megaptera novaeangliae ) play with seaweed in 2007 , but the behavior , known as " kelping , " is now so widespread , it ’s become a world-wide phenomenon . Seaweed potentially act as a consistency bush for the whales , and they may utilize it to remove parasites , cover their hide or just play with it .
" It ’s something they do together as a societal event or by themselves , " Olaf Meynecke , a investigator at Griffith University ’s Coastal and Marine Research Centre in Queensland , Australia , told Live Science in September . " They put the seaweed on their head and roam around in it ; they attempt to move it around with their thoracic V as well . "
Orca eats seven sea otters whole
In September , scientists discover a beachedorca(Orcinus grampus ) withseven intact sea otters in her belly . Orcas do n’t normally eat sea otter ( Enhydra lutris ) and typically jaw the marine mammals they do eat , so researchers were puzzled why this orca gobbled down the ocean otters whole .
To make matters even stranger , this killer giant was found on the glide of one of the Commander Islands in the Russian Far East , far from the orcas ' normal range between the Gulf of Alaska and the sea-coast of California . One of the sea otters was stick between the orca ’s oral tooth decay and esophagus , which could have been the reason for the orca ’s demise .
Ants detect cancer in urine
In January , researchers discovered thatantscansniff out Cancer the Crab using their antenna . Silky pismire ( Formica fusca ) normally use the olfactory receptors in their transmitting aerial to find food for thought or mates , but the researchers trained them to find tumor instead .
Once the ants learned to associate the urine of tumor - bearing rodents with sugar , the investigator found that the ants spent 20 % more time next to urine samples from cancerous rodent than next to urine sample from goodish rodents . The ants could swear out as cheap and efficient cancer detector in the future , though much more science take to be done first , the researchers said . Dogs can also find out to sniffle out malignant neoplastic disease , but researchers come up that pismire are easier to condition .
Mice kill largest flying birds
Invadingmice killed eight wandering albatrosses(Diomedea exulans ) — the world ’s great flying doll — on a remote island between South Africa and Antarctica . The mouse have been eating native seabird biddy on Marion Island for 10 , but take down adults is a newfangled phenomenon — and it ’s worrying conservationists .
Humans inadvertently introduce mansion mouse ( Mus muscle ) to the island in the nineteenth C after the gnawer hitch a drive on ships . The island ’s native wildlife is n’t fit out to defend itself against rodents because it did n’t evolve alongside the mice . The Mouse - Free Marion project will endeavor to use rodenticide to drink down off the mouse before they can do any further damage to wandering albatross and other threatened species that call the island home .
Orcas sink two boats
Orcas in the Strait of Gibraltarsank two boats in 2023 and attacked a bit of others withruthless efficiency . Why orcas have started attack sauceboat is an open question , but the behavior may halt froma traumatic experience , play , frustration or a irregular fad within the population .
In the 1980s , an orca population in the Pacific went through a form of carrying dead Salmon River on their heads for no obvious reason , so it ’s possible for orcas to pick up impermanent behaviors and learn them to each other . The interconnected gravy boat attacks are just one example of howorcas show their terrifying intelligence .
The dolphins learned how to steal crab bait out of pots and nets.
Scientists in India observed mugger crocodiles (Crocodylus palustris) interacting with a dog that had been chased into the river by a feral pack.
Humpback whales (Megaptera novaeangliae) playing with seaweed is a behavior known as kelping.
A stranded female orca (Orcinus orca) was found with six sea otters (Enhydra lutris) inside her stomach.
Since they don’t have noses, ants use their antennae to sniff out cancer.
Eight adult wandering albatrosses (Diomedea exulans) were found dead on Marion Island.
