This is the incredible story of a whale rescue and the response of the whale to her rescuers.
The humpback whale was on the migratory route around the California coast when she became terribly entangled in crab trap lines. Her life was at great risk.
She was tangled up in weighted ropes up to 240 feet long around her tail, her flipper and even in her mouth. The ropes were so tight they cut into her blubber and caused visible wounds. She was completely helpless and the weight of the traps was causing her to struggle to keep her blow hole out of the sea.
A rescue team of divers went out to her but she was in such a state they were unsure that they stood any chance of saving her. They were at risk themselves, as the flick of a humpback’s tail can kill a human.
But they reported that as they worked to free the unfortunate creature, she did not struggle at all and they were aware of her eyes simply following them around as they worked.
Thankfully, the rescuers were successful but must have been astonished by the whale’s heartwarming response. When she felt herself come free, she began to swim around in circles and then went up to each diver one by one and nudged them. One of the rescuers is reported as saying: “It seemed kind of affectionate, like a dog that’s happy to see you … I never felt threatened. It was an amazing, unbelievable experience.”
Her response makes us think about the common ground that humans can have with animals who might appear so very different from us. A whale-watching expert who helped co-ordinate the rescue is quoted as saying: “You hate to anthropomorphize too much but the whale was doing little dives and the guys were rubbing shoulders with it … I don’t know for sure what it was thinking, but it’s something that I will always remember. It was just too cool.”
An interesting point about our understanding of these large sea mammals was made by Gould and Gould in their book ‘The Animal Mind’. They suggest that perhaps we have been quicker to appreciate the intelligence and sentience of primates as they are so much more similar to us in their gestures and experiences, and therefore easier for us to read. We may have been slower to understand the complexity and richness of underwater creatures simply because they appear to be so very different to us.
Horses have played a huge part in our lives for hundreds of years. Yet how much do we actually know about them?
Animal welfare consultant Heather Pickett has written a special article for our animal sentience pages. It’s a fascinating read about horses’ behaviour, cognitive abilities (such as ‘thinking’) and welfare needs. Horses have remarkably complex social lives; with membership of a herd being of ultimate importance to them and sometimes roaming for up to 80km in one day. They are great diplomats, able to resolve many conflicts in order to keep the herd together.

Mares often form lifetime relationships, spending most of their time together. Their foals often become good friends too as a result. They have remarkable memory skills and have even been shown to understand that a 3-D image can be shown in a photograph. For example, horses had been trained to have a ‘favourite’ object (for example a soft toy or a frisbee), using treats as positive reinforcement. Then they were shown photos of a range of things, including their ‘favoured toy’, and more often than not they would choose the photo of that toy. In a similar experiment (Stone 2009), horses were found to be able to tell the difference between photos of people, even identical twins!
Domesticated horses are often kept stabled alone and fed on concentrated food that is eaten quickly, rather than grazing the whole day as they would do in more natural conditions. These factors sometimes lead to destructive behaviours such as weaving, biting the stable doors and pacing. The occurrence of these unnatural behaviours illustrates that horses, just like many other animals, need an environment that more closely fits their needs and fully takes into account their sentience and intelligence.
Horses are great at reading body language, even that of the humans around them – in fact a horse known as ‘Clever Hans’ was able to answer mathematical questions by tapping his hoof, based on the very subtle signals given out by the person asking the question! Even though they didn’t mean to give any secret messages to the horse, he could read small changes in facial expression or intakes of breath – and then work out what the right answer was!
Clever Hans
At the time, people thought he was working out the maths himself, and were disappointed to learn that he was reading their body language instead. But the fact that Hans could answer the questions by this method is in itself amazing. He was seeing small changes in the behaviour of his questioners which people did not see – and it took an extensive experiment for us to find out what Hans knew all along.
Other animals are also more tuned in to us than we might expect. In a previous post about Sociable sheep we found out that sheep preferred the faces of smiling people rather than stressed or angry people.
This leads us to consider, how much do animals really know about what we’re thinking?

The ability to co-operate with your companions is believed to show a higher level of thought – and is an ability once thought to be unique to humans. In a recent study hyenas were found to be great team players, with a 100% success rate in a group challenge. They had to work together to reach food from a platform which they couldn’t get to alone. It was even found that when a hyena who had worked out the ‘platform puzzle’ was paired up with one who was new to it, the experienced hyena changed his behaviour – as we would when showing someone a new task.

Chimps in Japan have been seen helping their companions out, purely on the basis of need. They would hand tools over to chimps in a nearby pen; and most notably this was most likely to happen if the chimp really needed the tool and requested it, rather than if they just wanted it to play with. This shows that chimps care about the welfare of their fellows and will assist them even if there is nothing to be gained themselves.
This helping is not just reserved for other chimps too – in a previous study by Warneken, chimps were also witnessed helping humans in a similar task and handing a stick to them on request. Videos of both of these experiments can be found below.

If by the word ‘language’ we mean a system of communication, animals have different languages of their own. Hens and chickens have over 30 different calls, which they use to alert their group to food or danger, for example. Chicks start communicating with their mother hen while they are still in the egg and cockerels have a special food call to let the hens know that food has been found. Hens make a gentle crowing sound when they are happy.

Pigs are very chatty, communicating with grunts, squeals, snarls and snorts, champing their jaws and clacking their teeth. Sows have a special call for their piglets when it’s time for the piglets to suckle. Sows and piglets keep contact with each other and with their mother by squeals and grunts. If piglets are separated from Mum, they squeal for her. Scientists found that sows responded more strongly to the desperate squeals from cold, hungry piglets than they did to calls from larger, more well-fed piglets.
Animals can also understand each other’s language. For example, some animals can understand the meaning of another’s alarm call.
Dogs and humans have a long history of living together. While dogs are often quick are picking up what humans are saying – perhaps by the tone of voice rather than by all the actual words – we humans often seem to struggle to understand dog ‘bark language.’ In this really interesting video, courtesy of the social networking site Petstreet , dog communication expert John Rogerson helps us decipher what our furry friends are wanting to tell us.
Sakura, a baby chimpanzee, is showing that chimps prefer melodic music. During a research trial to see which kind of music Sakura would chose, she preferred to listen to a pleasant melody than to discordant musical chords.

This shows us more fascinating evidence about the sentience of chimps. In this case, Sakura is in a human-designed, captive environment, which may be somewhat enriched, but which is still unnatural for a chimp. The fact that Sakura works out what to do in these circumstances tells us even more about chimp awareness and understanding. These abilities are strong indicators of animal sentience.
Sakura is not alone in preferring sweet music. Back in 2001, there was research investigating how cows reacted to fast beats or to softer music. The researchers said: “We found that slow music improved milk yields perhaps because it relaxes the cows in much the same way as it relaxes humans.”
Despite increasing awareness of animal sentience, there is still resistance to appreciating or acknowledging that animals are sentient beings and there is reluctance to peer over the barrier of “human vs other animals” that we ourselves have created.

It was previously thought that this kind of choice and preference about music was a “uniquely human trait.” So we see that Sakura and the dairy cows have overcome yet another barrier!
As reported in the Daily Mail, Clyde is blind, and Bonnie leads him “to food or water, and lets him rest his head on her haunches when he feels a bit lost. They are inseparable, and if Bonnie isn’t nearby Clyde refuses to move a paw.”
Bonnie and Clyde were rescued as strays recently and now they happily have a new home. The BBC’s One Show has a special page and film about these two great friends.
Mila is a beluga whale at an aquarium in Harbin, NE China. The pool she lives in has an arctic temperature and is also used by divers. In a recent exercise, diver Yang Yun got into trouble and was unable to kick her way back up the surface. But suddenly she felt herself being pushed upwards – Mila was rescuing her.
According to reports, “Mila had spotted her difficulties and using her sensitive dolphin-like nose guided Yun safely to the surface.”
One of the staff is quoted as saying: “Mila noticed the problem before we did. She’s a sensitive animal who works closely with humans and I think this girl owes her her life.”
Belugas are very social and because they are so chatty, they are also known as sea canaries. When you have to swim great distances under ice in the Arctic Sea, it helps to be a good communicator so you can keep up with your pod and let each other know what’s going on. Sadly, beluga whales are yet another threatened species.
