Sloths' reputation as lazy, slow and stupid creatures owes much to French naturalist Georges Buffon, who described the tree-dwelling mammal as the 'lowest form of existence' back in 1749. Buffon's assessment has endured for centuries, but much of the criticism directed at sloths is unwarranted. As zoologist Lucy Cooke explains for The Day, the sloth's sluggish lifestyle is a deliberate survival strategy that has enabled it to maintain a place on Earth for nearly 64 million years.
But sloths don't just live life in slow motion: They might even be able to put their metabolism on pause, a new study published in PeerJ suggests. The slowpoke is now the only mammal known to be capable of temporarily shutting down its metabolism without entering into a state of lethargy or hibernation, a behavior that's more typical of reptiles and birds, Jason Bittel reports for National Geographic.
According to a blog post published on the Costa Rica-based Sloth Conservation Foundation's website, this scenario plays out when sloths experience very hot or cold temperatures. Most mammals facing similarly extreme conditions, or those that fall outside of a comfortable temperature range known as the thermoneutral zone, respond in a manner completely anathema to the sloth's slow-down.
Within the thermoneutral zone, most mammals can control their body temperature without using up too much energy, but outside of it, they must expend vast amounts of energy. As zoologist Rebecca Cliffe, the study's lead author and co-founder of the Sloth Conservation Foundation, tells Bittel, animals' physical responses to hot and cold, such as shivering, sweating and panting, help them regulate their internal temperature but take a heavy toll on energy levels.

Reptiles and birds, on the other hand, don't have a thermoneutral zone. When it's cold, they expend minimal amounts of energy, and when it's hot, they use lots of energy. As the foundation notes, this occurs because the animals are unable to control their body temperatures, and metabolic processes tend to work faster at hotter temperatures regardless of whether they're operating in mammals, cold-blooded critters or avian fliers.
Scientists have long known that sloths defy easy categorization. Sloths are often likened to reptiles, Cliffe writes for The Conversation, because they both adopt a slow pace in order to conserve energy. It would make sense, therefore, for sloths experiencing high temperatures to exhibit a higher metabolic rate and sloths experiencing low temperatures to use up very little energy.

To test this hypothesis, Cliffe and her team placed eight three-fingered sloths into individual, temperature-controlled chambers and monitored their oxygen levels as the temperature rose and fell. As the chambers got hotter, the sloths used up more oxygen (and energy), but once the thermostat hit 86 degrees Fahrenheit, energy levels started sliding back down.

This reduction in metabolic rate at high temperatures is the exact opposite of what typically happens in all other animals.
Instead of using up vast amounts of energy when trying to cool down, the sloths in the study actively depressed, or slowed down, their metabolism—and they did it without entering a state of torpor, aestivation or hibernation (essentially all synonyms for periods of intentional inactivity).
When other large mammals face extremely hot or cold temperatures, they can enter a similar hypometabolic, or lowered metabolism, state, but in doing so, they tend to become lethargic. As Roberto Nespolo, an evolutionary biologist at the Austral University of Chile, tells National Geographic's Bittel, such states find the animals' body temperatures dropping dramatically and rendering them unresponsive. The sloths, however, maintained their body temperatures while remaining fully awake.

Nespolo says the team's new findings remind him of birds' energy patterns. King penguins, for example, appear to conduct deep sea hunts without warming their stomachs, potentially saving energy and enabling them to stay underwater for longer periods of time.
The explanation behind this unexpected strategy is likely related to the 'metabolic knife edge' Cliffe says sloths navigate on a daily basis. All animals must balance the energy they consume with energy taken in to ensure their survival; for sloths, this is a highly tenuous task. Sloths can only eat a specific group of leaves, and unlike most animals' nutrient-rich food sources, these leaves are both lacking in nutrition and difficult to digest. As a result, sloths have to keep a careful eye on the amount of energy they use each day.
Ultimately, sloths facing scorching temperatures can probably do little beyond moving into the shade and lying still rather than wasting energy on panting, sweating or similar cool-down efforts.
'You depress your metabolism and you just sit still and wait for the heat to pass,' Cliffe tells Bittel. 'So it does make sense, but it was totally unexpected.'
Question: 'What does the Bible say about laziness?'Answer: Newton's first law of motion states that an object in motion tends to remain in motion, and an object at rest tends to remain at rest. This law applies to people. While some are naturally driven to complete projects, others are apathetic, requiring motivation to overcome inertia. Laziness, a lifestyle for some, is a temptation for all. But the Bible is clear that, because the Lord ordained work for man, laziness is sin. 'Go to the ant, you sluggard! Consider her ways and be wise' (Proverbs 6:6).
The Bible has a great deal to say about laziness. Proverbs is especially filled with wisdom concerning laziness and warnings to the lazy person. Proverbs tells us that a lazy person hates work: 'The sluggard's craving will be the death of him, because his hands refuse to work' (21:25); he loves sleep: 'As a door turns on its hinges, so a sluggard turns on his bed' (26:14); he gives excuses: 'The sluggard says, ‘There is a lion in the road, a fierce lion roaming the streets'' (26:13); he wastes time and energy: 'He who is slothful in his work is a brother to him who is a great waster' (18:9 KJV); he believes he is wise, but is a fool: 'The sluggard is wiser in his own eyes than seven men who answer discreetly' (26:16).
Proverbs also tells us the end in store for the lazy: A lazy person becomes a servant (or debtor): 'Diligent hands will rule, but laziness ends in slave labor' (12:24); his future is bleak: 'A sluggard does not plow in season; so at harvest time he looks but finds nothing' (20:4); he may come to poverty: 'The soul of the lazy man desires and has nothing; but the soul of the diligent shall be made rich' (13:4 KJV).
What Is A Sloth Animal
There is no room for laziness in the life of a Christian. A new believer is truthfully taught that '…it is by grace you have been saved, through faith—and this not from yourselves, it is the gift of God—not by works, so that no one can boast' (Ephesians 2:8-9). But a believer can become idle if he erroneously believes God expects no fruit from a transformed life. 'For we are God's workmanship, created in Christ Jesus to do good works, which God prepared in advance for us to do' (Ephesians 2:10). Christians are not saved by works, but they do show their faith by their works (James 2:18, 26). Slothfulness violates God's purpose—good works. The Lord, however, empowers Christians to overcome the flesh's propensity to laziness by giving us a new nature (2 Corinthians 5:17).
In our new nature, we are motivated to diligence and productiveness out of a love for our Savior who redeemed us. Our old propensity toward laziness—and all other sin—has been replaced by a desire to live godly lives: 'He who has been stealing must steal no longer, but must work, doing something useful with his own hands, that he may have something to share with those in need' (Ephesians 4:28). We are convicted of our need to provide for our families through our labors: 'If anyone does not provide for his relatives, and especially for his immediate family, he has denied the faith and is worse than an unbeliever' (1 Timothy 5:8); and for others in the family of God: 'You yourselves know that these hands of mine have supplied my own needs and the needs of my companions. In everything I did, I showed you that by this kind of hard work we must help the weak, remembering the words the Lord Jesus himself said: 'It is more blessed to give than to receive'' (Acts 20:34-35).
As Christians, we know that our labors will be rewarded by our Lord if we persevere in diligence: 'Let us not become weary in doing good, for at the proper time we will reap a harvest if we do not give up. Therefore, as we have opportunity, let us do good to all people, especially to those who belong to the family of believers' (Galatians 6:9-10); 'Whatever you do, work at it with all your heart, as working for the Lord, not for men, since you know that you will receive an inheritance from the Lord as a reward. It is the Lord Christ you are serving' (Colossians 3:23-24); 'God is not unjust; he will not forget your work and the love you have shown him as you have helped his people and continue to help them' (Hebrews 6:10).
