I was eight years old and wasn’t aware of all the arrangements being made for our journey as a family to London in 1950. My mother was in great pain and wished to visit specialists in London. My father reluctantly had to sell our property in Queensland. The day before we boarded the ship, Father unwillingly said goodbye to his five-year-old cattle dog, Spider, who was loved by us all. Father’s friend Sandy was to be his guardian while we were overseas, as he had been getting to know Spider for many weeks.
Six weeks later, an airletter arrived from Sandy, giving my father the news that Spider had run away just two weeks after we had sailed. Sandy had advertised constantly on ABC and other regional newspapers. Despite many “sightings”, the dog was never found. It seems Spider just kept running and searching for us. As he was cattle dog, my father thought he would shoe or dingo-trapped, because of his appearance. But our family thought that Father held a secrets hope that Spider was still alive.
We sailed back to Australia two years later and re-established our home. My father immediately began his own search for Spider. One cold winter’s Saturday morning eight months after our return, my father had a call from an elderly lady living on her own on the outskirts of the town. As she told my father on the telephone, it was “just glimpses of a dingo-type dog in the shadows” of her disused tennis court. That was enough for my father to interrupt my homework.
We set off in his blue and black Jensen car which he had brought back from England. It was hardly the right vehicle for the rough roads we travelled that day. Five and a half hours later, we found the run-down old property. Sadly, she told my father that the “dingo dog” hadn’t been around for a few days. My father had a strange look in his eye. He put two fingers to his lips and did his special whistle for Spider.

Last summer, Hilda worked as a volunteer with dolphin trainers at a sea life park. Her job was to make sure the tanks were free of any items so that the trainers could train the dolphins to fetch specific items. However, one day after cleaning, one of the dolphins, Maya, presented Hilda with a candy wrapper from the tank. When Katherine, the trainer, saw this, she blamed Hilda for her carelessness. Upset but not discouraged by this event, Hilda decided to do some spying on Maya.
The next morning, Hilda arrived at the park early. She put on her scuba gear (水下呼吸器) and jumped into the tank for her usual, underwater sweep. Finding nothing in the tank, she climbed out of the water just in time to see Katherine jumping in on the other side. After what happened yesterday, Hilda knew what she was doing. She watched as Katherine performed her underwater search, but Hilda wasn’t surprised when she surfaced empty-handed.
During the tank sweeps, Maya had been swimming playfully, but now the dolphin stopped suddenly and swam to the back part of the tank where the filter (过滤) box was located. She stuck her nose down behind the box and then swam away. What was Maya doing back there? Hilda wondered. She jumped back into the water and swam over to take a look behind the box, and her question was answered. Hilda then swam across the tank following Maya’s path and emerged from the water to find Katherine removing her scuba gear. As Katherine turned around, her mouth dropped open. There was Maya at the edge of the tank with a comb (梳子) in her mouth waiting for her treat.
“Maya! Where did you get that?” demanded Katherine, taking the comb and throwing her a fish. “I know where she got it,” declared Hilda climbing out of the tank with a handful of items still wet from their watery, resting place. “What’s all this?” Katherine asked, obviously confused.

Parrots are prey animals, which means that other predators (捕食者) in the wild, such as hawks or snakes, are looking to make them into a meal. This one factor influences parrots’ behavior in your house more than any other.
Parrots are most easily hurt when feeding on the ground. Membership in a group plays an important function in ensuring their safety and improving their chances of survival from attacks by predators. The most common predators of parrots include hawks, snakes, cats, monkeys, and bats. Some predators make attacks only during the day while others hunt in the night.
As prey animals, parrots are constantly watching out for danger and they instinctively (本能地) react to risks. Their first choice is to take flight. However, if this is not possible, they will fight with their powerful beaks to defend themselves.
Because their biggest enemy is the hawk, parrots are especially reactive to quick movements from above and behind. For this reason, it is wise to avoid quick, sudden movements near your bird. This is a built-in reaction not subject to logic or reason. Simple and relatively harmless household objects can draw extreme fear responses from a bird. For example, a balloon may represent a hawk or a vacuum hose (吸尘器软管) may be the same as a snake in your bird’s mind.
As prey animals, parrots are often frightened by exposure to new household items or strangers. It is important to expose your bird to safe experiences and changes starting at a very young age to build flexibility and improve their adaptability. Variety in diet and toys, travel, and exposure to new people and places all help to make your bird more flexible and adaptable to change.

5 . Young soldiers, far away from home and missing their families, discover a bear cub. That’s how the story of Wojtek begins, back in 1942. He was alone in the mountains of Iran; nobody knows how he got there.
When the exhausted Polish soldiers came upon Wojtek, they were immediately struck with emotions. They had been away from their loved ones for a long time. They needed something to pick their spirits up. So, they nursed the baby bear with milk from a bottle and named him Wojtek, which means: a warrior to whom fighting brings joy.
Wojtek was officially adopted into the army. He traveled with the army to the Middle East, providing comradery and entertainment. He would wrestle with the men, chase after oranges they cast for him and follow them about like a puppy. He became their connection to humanity in a time when the light of peace seemed so far away. And, like a child, he was also playful. In the desert heat, he learned how to break into the showers and turn on the water. He could also be seen pulling trunks of empty gun shells with the men or standing at attention in formation. Wojtek was also the chief frightener of new members: He would literally bear hug them and hold them upside down for a good laugh.
Getting through the hardship of war takes something extraordinary, something unexpectedly dangerous to preserve your mental state. That’s what Wojtek did for the men who had been so long in the fog and uncertainty of World War II. A playful bear became the symbol of strength and adaptability. Thankfully, wars ended but Wojtek was not forgotten. He was shipped with a group of men to a farm in Scotland, which was a fitting place to retire for a bear with so much military experience. Wojtek was a local celebrity. Stories of him kicking a soccer ball, attending local dances and parties, and enjoying jam and honey are still told today. And to everyone who knew him, Wojtek was the one that made a difficult time a little more bearable.

6 . A blue hole is a special kind of underwater cave found inland or in the sea, which forms when the earth above a cave falls in and water fills the space.
An inland blue hole’s water is very still and has different layers. A layer of fresh rainwater floats on top of salt water; the fresh water keeps oxygen from the atmosphere from reaching the salt water; brightly colored bacteria live where the two layers meet.
Diving into blue holes is very dangerous. Near the top of the blue hole, there is a layer of toxic gas, which causes itching, headache, and—in large amounts—death. Divers must also be fast. They have to get in and out of a cave before their oxygen runs out. Additionally, divers have to follow a guideline as they swim through a blue hole because it is very dark inside. Without the guideline, they may get lost.
If blue holes are so dangerous, why do explorers and scientists risk their lives to explore them? The reason is that these underwater caves can provide valuable scientific information. They provide clues about geology, archaeology, and biology. For example, some blue hole creatures probably haven’t changed for millions of years.
The blue holes could even provide clues about astrobiology. For example, divers have found bacteria there that can live without oxygen. Astrobiologist Kevin Hand says the bacteria may be similar to forms of life that might exist on Jupiter’s fourth largest moon, Europa. “Our study of life’s extremes on Earth,” he says, can help increase “our understanding of habitable environments off Earth.”
In addition, the oxygen-free environment of the blue holes preserves bones of humans and animals that fell into the caves long ago. By studying blue holes, we can understand what life was like in prehistoric times. As cave diver Kenny Broad says, “I can think of no other environment on Earth that is so challenging to explore and gives us back so much scientifically.”

7 . Endangered polar bears are breeding (繁殖) with grizzly bears (灰熊), creating “pizzly” bears, which is being driven by climate change, scientists say.
As the world warms and Arctic sea ice thins, starving polar bears are being forced ever further south, where they meet grizzlies, whose ranges are expanding northwards. And with that growing contact between the two come increasing hybrids (杂交种).
With characteristics that could give the hybrids an advantage in warming northern habitats, some scientists guess that they could be here to stay. “Usually, hybrids aren’t better suited to their environments than their parents, but these hybrids are able to search for a broader range of food sources,” Larisa DeSantis, an associate professor of biological sciences at Vanderbilt University, told Live Science.
The rise of “pizzly” bears appears with polar bears’ decline: their numbers are estimated to decrease by more than 30% in the next 30 years. This sudden fall is linked partly to “pizzly” bears taking up polar bears’ ranges, where they outcompete them, but also to polar bears’ highly specialized diets.
“Polar bears mainly consumed soft foods even during the Medieval Warm Period, a previous period of rapid warming,” DeSantis said, referring to fat meals such as seals. “Although all of these starving polar bears are trying to find alternative food sources, like seabird eggs, it could be a tipping point for their survival.” Actually, the calories they gain from these sources do not balance out those they burn from searching for them. This could result in a habitat ready for the hybrids to move in and take over, leading to a loss in biodiversity if polar bears are replaced.
“We’re having massive impacts with climate change on species,” DeSantis said. “The polar bear is telling us how bad things are. In some sense, “pizzly” bears could be a sad but necessary compromise given current warming trends.”

8 . What makes people so special? Tool use, self-consciousness, language, and culture are high on the list, but in fact all of these characteristics can be found elsewhere in the animal kingdom. Humans and apes are close relatives, so it is perhaps not surprising that chimpanzees use tools or that gorillas (大猩猩) have a sense of fair play, even rejecting carrots (which they normally accept) when they see their neighbors getting grapes. But the qualities that we often think of as uniquely human exist not just on land, but in the ocean as well.
Among the invertebrates, octopuses (八爪鱼) are known for their intelligence, even exhibiting evidence of playfulness, tool use, and personality. But these skilled predators live alone and consequently lack culture. Dolphins, on the other hand, are large-brained, long-living, social- group-based predators, and it is here that we find the greatest similarity to human-like culture and awareness.
Culture depends on the ability of animals to pass on things they have learned to others. Many animals have culture in this sense, but what sets dolphins apart is what they pass on. Some bottlenose dolphins hold sponges in their mouths that they use as tools to sweep for fish hiding on the ocean floor. This ability is handed down through generations (especially in females), with some families — grandmother, mother, and daughter — all feeding in this highly specialized way.
Another characteristic that dolphins share with humans is their ability to recognize themselves in a mirror. When facing a mirror, most animals behave as though they are interacting with another individual. Even in humans, the ability to recognize that the image in a mirror is oneself does not occur before the age of 18 months. Dolphins not only recognize themselves, but if a black mark is put on the body of a dolphin, it will spend extra time at the mirror to look at the mark.

9 . Any parent of growing teenagers knows their kids’ appetite (食欲) can be extremely large. Now, imagine having a young dinosaur checking the fridge. The out size appetites of growing dinosaurs reshaped food chains in their environment and crowded out other carnivores (食肉动物), according to a new study.
Most groups of animals have many small-sized species, somewhat fewer medium-sized species and the fewest large-sized species. However, the extinct dinosaurs—especially carnivores had plenty of species no bigger than modern-day chickens and also many extremely big species, but few medium-sized ones.
Scientists wondered whether teen dinosaurs crowded out medium-sized adults by taking advantage of the habitats and food sources those species might have taken. To test the idea, Katlin Schroeder, a Ph. D. student at the University of New Mexico (UNM), combed a global collection of data to determine the size of more than 550 dinosaur species in 43 ancient ecosystems.
“In most communities, plant-eating dinosaurs were in multifarious sizes. But carnivores were completely different,” Schroeder says. Plant-eating dinosaurs came in a range of sizes, while carnivorous dinosaurs between 100 and 1, 000 kilograms were quite rare. “The size of the carnivorous dinosaur is surprising. It’s as if you went to the savanna, a large flat area of grassy land, and saw nothing in size between a small fox and a lion,” Schroeder says. “Patterns in all the dinosaur communities studied are very similar. We saw the gap in species’ sizes for years, but never measured it.”
Schroeder and paleontologists Eelisa Smith of UNM and Kathleen Lyons of the University of Nebraska, Lincoln, modeled the role that young carnivorous dinosaurs might have played in ecosystems. “If the teen dinosaurs are really using up this space, how many of them would you expect?” Smith says. Their study showed that “the teenagers fill the gap,” she says. “If you fill them in, then you get a community that looks like what you’d expect.”
“The effect maybe stronger in meat eaters because each carnivorous dinosaur species hatched (孵化) from small eggs; then they grew very quickly. They had to change diets and hunting methods to adapt to their new sizes and compete with a range of other species along the way,” Erickson, another scientist, says.
“The study’s stress on how animals’ niches (生态位) can change as they grow offers fresh understandings,” says Mike Benton, a scientist at the University of Bristol.
