AY Honors/Camelids/Answer Key

1. Explain the differences between the Dromedary and the Bactrian camel. Why are both recognizable and important?

There are two (or three counting wild) subspecies of camel.

Dromedary or Arabian

• One hump
• Hot climates. Original habitat was southern Asia and the Middle East, but now they can be found throughout the desert regions of the Middle East, India and Africa.
• much shorter coat
• typically brown, however, there are also black and white individuals, with almost every shade in between
• padded feet ideal for sand, that can easily be punctured by stones and other sharp objects.
• one baby at a time
• babies are dependent on their mothers for anywhere from 12 to 24 months
• they tend not to breed until they are about three years old for females, and six years old for males
• much more common

Bactrian

• two hump
• Cold climates Much more northern climate than the dromedary including the Siberian steppe and the cold, arid deserts of Central and Eastern Asia. In the winter, temperatures in their native habitat can drop as low as –29° Celsius (–20° F).
• long, shaggy coat that helps protect them in the cold winter months. They shed their long fur in the summer, when they are faced with high temperatures
• typically dark brown to beige in coloring,
• wide feet that facilitate walking across snow and sand, but their feet are tougher and can stand up to their more rocky environment
• one or two babies (although one is much more common) and continue nursing them for up to a year and a half. The young aren’t completely independent until they’re five years old, thought they can bear young of their own between three and five years.
• Much rarer, severely threatened in the wild

The domesticated Bactrian camel has served as a pack animal in inner Asia since ancient times. With its tolerance for cold, drought, and high altitudes, it enabled travel such as the caravans of the Silk Road.The wild form has dwindled with limited remaining populations. ts range in the wild is restricted to remote regions of the Gobi and Taklamakan Deserts of Mongolia and China, migrating from the desert to rivers in Siberia during winter. A small number of wild Bactrian camels still roam the Mangystau Province of southwest Kazakhstan and the Kashmir valley in India. There are feral herds of Bactrian camels in Australia.

The two types are sometimes bred together, producing an even bigger, stronger camel useful for plowing and other work. Camel wrestling (a sport where male camels are exposed to an in heat female and then allowed to fight each other) almost exclusively uses cross bred camels.

Recent research suggests that wild camels may be another species, possessing a different number of chromosomes.

2. Describe the following characteristics of camels:

a. Three uses attributed to them

1. Pack animals. As pack animals, the bactrains are virtually unsurpassed, able to carry 170–250 kg (370–550 lb) at a rate of 47 km (30 miles) per day, or 4 km/h (2 mph) over a period of four days.
2. Source of milk, used for drinking, cheese, yogurt etc
3. Source of fiber and leather for various uses
4. Used for sport - camel racing and camel wrestling are examples

b. Amount of water they drink

Camels can go for months without water, but when they drink they can gulp down up to 57 liters at once.

c. Three survival traits

1. Bactrian camels belong to a fairly small group of animals that regularly eat snow to provide their water needs. Any animals living above the snowline are obliged to do this as snow and ice are the only forms of water during winter, and by doing so their range is greatly enlarged. The latent heat of snow and ice is enormous compared with the heat capacity of water, demanding a large sacrifice in heat energy and forcing animals to eat only small amounts at a time.

1. While camels are herbivores, in times of scarcity they have been known to gnaw on bones, eat shoes, gobble up tents and other weird things.

1. Camels can eat plants that are dry, prickly, salty and/or bitter and can ingest virtually any kind of vegetation. Their ability to feed on a wide range of foods allows them to live in areas with sparse vegetation. With tough mouths that can withstand sharp objects such as thorns, the digestion process begins. The first time food is swallowed it is not fully chewed. The partly masticated food (called cud) goes into the stomach and later is brought back up for further chewing.

1. Wild Bactrian camels can drink salt marsh water but domesticated ones can not.

d. Origin

God made camels and they were on the ark. |Research shows the Bactrian camel is thought to have been domesticated (independently of the dromedary) sometime before 2500 BCE, in Northeast Afghanistan, or southwestern Turkestan. The dromedary camel is believed to have been domesticated between 4000 BCE and 2000 BCE in Arabia but more likely at least some camels were always domesticated.

3. Name three South American camelids and analyze the following:

The question is a little misleading as there are four recognized species of South American camilids. llama, alpaca (two fiber types), vicuñas, and guanacos.

a. Region where it lives

Vicuñas live exclusively in South America, primarily in the central Andes at altitudes of 3,200 to 4,800 m. They are native to Peru, northwestern Argentina, Bolivia, and northern Chile, with a smaller, introduced population in central Ecuador. Peru has the largest number.

Guanaco are found in the altiplano of Peru, Bolivia, Ecuador, Colombia, Chile, and Argentina. Some Guanacos live in the Atacama Desert, where in some areas it has not rained for over 50 years. A coastline running parallel to the desert enables them to survive. Where the cool water touches the hot land, the air above the desert is cooled, creating a fog and thus, water vapor. Winds carry the fog across the desert, where cacti catch the water droplets and lichen that cling to the cacti soak it in like a sponge. When the guanacos eat the cacti flowers and the lichen, the water is transferred to them.

As domesticated versions of their wild cousins llamas and alpacas were confined to South American until exported to North America, Europe, Australia and elsewhere as livestock in the 1980s.

b. Different uses attributed

1. fiber harvesting (domestic and wild)
2. meat
3. dung used as fertilizer and fuel
4. llamas used as pack animals

c. Physical characteristics

All the South American Camilids have similar body features including a long neck and soft fiber. The current forms of the domesticated llama and alpaca (and perhaps their wild cousins) are undoubtedly the result of selective breeding for either the size and strength of the llama or the soft fiber of the alpaca. The differences are similar to differences in breeds of dogs since the South American camilids can all be easily interbreed with fertile crosses resulting. Recently scientists in the UAE used artificial insemination (to overcome the size issue) to bred a llama to a camel successfully and called it a "cama."

The main differences between the species is size and fiber quality and domestic vs wild status.

Vicuña are wild, 35 to 65 kg (77 to 143 lb) with super soft, sort fiber

Alpaca are domestic, 48 to 84 kg (106 to 185 lb) with long soft fiber

Guanaco are wild, about 90 kg (200 lb) with short soft fiber

Llama are domestic, about 130 to 200 kg (290 to 440 lb) with courser fiber

d. Diet

All camelids eat vegetation, including pretty much anything they can find. In their natural habitat food can be very scarce.

4. Do some research on predation of South American camelids. Why are these animals endangered?

The domesticated alpaca and llama are not endangered. They have been exported to many countries in the world and in the US and Canada at least, supply exceeds demand.

Both under the rule of the Inca and today, vicuñas have been protected by law, but they were heavily hunted in the intervening period. Before being declared endangered in 1974, only about 6,000 animals were left. Today, the vicuña population has recovered to about 350,000, and although conservation organizations have reduced its level of threat classification, they still call for active conservation programs to protect populations from poaching, habitat loss, and other threats. The species is listed as Least Concern.

Hunting was also an issue for the guanaco but similar conservation efforts resulted in the species being listed least concern. Estimates, as of 2011, place their numbers at 400,000 to 600,000. They have only one natural predator, the mountain lion. A few hundred guanaco are held in zoos and on farms successfully.

5. Complete a Bible study about the verse Matthew 19:24, emphasizing Jesus's words. Write 200 words about what was learned in this lesson (use Bible commentaries to understand the context; it is necessary to read all of Matthew chapter 19).

Jesus is talking about the difficulty of

6. Research five Bible verses that mention camels.

There are about 59 total verses that reference camel(s), camel hair and a camel saddle in the Bible. Here are all of them grouped chronologically:

Patriarch used Camels

Job owned 3,000 camels in Job 1:3 but he lost them in Job 1:17 before the Lord gave him 6,000 camels by Job 42:12.

Genesis 12:16 Abram/Abraham owned camels and in Genesis 24 sent them with his servant to Nahor where Rebekah was. After Rebekah waters the camels she and others rode the camels.

Jacob acquired camels Genesis 30:43 and used them for riding and as pack animals Genesis 31:17 and Genesis 32:7

In Genesis 31:34 Rachel hid an idol in her camel saddle, while sitting in the tent.

In Genesis 32:15 Jacob gifted 30 female camels and their young to his brother Esau.

In Genesis 37:24-26 we see that the caravan of Ishmaelites coming from Gilead had camels loaded with spices, balm and myrrh, and and were heading to Egypt. Joseph is sold by his brothers to the traders with the camels.

Camels in Egypt and the Exodus

In Exodus 9:2-4 we learn the Egyptians had camels along with horses, donkeys, cattle, sheep and goats (the Israelites might also have had camels, as the text says they had livestock too, but that God would not harm the Israelite's animals.

God in Leviticus 11:4 and Deuteronomy 14:7 declares that camels are unclean and should not be eaten.

Judges

It was impossible to count the Midianites or their camels in Judges 6:5 when they invaded the land to ravage it. Also in Judges 7:12 "The Midianites, the Amalekites and all the other eastern peoples had settled in the valley, thick as locusts. Their camels could no more be counted than the sand on the seashore."

In Judges 8 we learn that some Midianite camels wore ornaments and chains on their necks (which could be gold from the context). Gideon and others took these off the camels necks.

United Kingdom

In 1 Samuel 15:3 God commanded that the Amalekites be totally destroyed. "Do not spare them; put to death men and women, children and infants, cattle and sheep, camels and donkeys."

According to 1 Chronicles 5:21 In the days of Saul "they (the Israelites) seized the livestock of the Hagrites—fifty thousand camels, two hundred fifty thousand sheep and two thousand donkeys. They also took one hundred thousand people captive."

David's practice was to take plunder, including camels according to 1 Samuel 27:9

Four hundred young Amalekite men escaped David's band by riding off on camels in 1 Samuel 30:17-18

1 Chronicles 12:40 says that "neighbors from as far away as Issachar, Zebulun and Naphtali came bringing food on donkeys, camels, mules and oxen" while David's army was growing.

1 Chronicles 27:30 "Obil the Ishmaelite was in charge of the camels" for King David.

The Queen of Sheba (modern Ethiopia) used camels as pack animals in 1 Kings 10:2 and the parallel account in 2 Chronicles 9:1 when she came to see King Solomon.

Divided Kingdom, Exile and Return

2 Kings 8:9 says that "Hazael went to meet Elisha, taking with him as a gift forty camel-loads of all the finest wares of Damascus. He went in and stood before him, and said, “Your son Ben-Hadad king of Aram has sent me to ask, ‘Will I recover from this illness?’”"

King Asa's army when fighting the Cushites in 2 Chronicles 14:15 "also attacked the camps of the herders and carried off droves of sheep and goats and camels."

Isaiah 21:7 mentions riders on camels. Isaiah 30:5-7 says "A prophecy concerning the animals of the Negev: Through a land of hardship and distress, of lions and lionesses, of adders and darting snakes, the envoys carry their riches on donkeys’ backs, their treasures on the humps of camels, to that unprofitable nation, to Egypt, whose help is utterly useless. Therefore I call her Rahab the Do-Nothing."

Isaiah 60:6 mentions "Herds of camels will cover your land, young camels of Midian and Ephah." and Isaiah 66:20 proposes people will come on camels to Jerusalem to worship.

Jeremiah 2:22-24 compares Israel to a sexually excited "swift she-camel running here and there"! Now that's a graphic metaphor.

Jeremiah writes in Jeremiah 49 that the Kedar and the kingdoms of Hazor, which Nebuchadnezzar king of Babylon attacked will lose their camels.

Ezra's band of returning exiles had "736 horses, 245 mules, 435 camels and 6,720 donkeys." Ezra 2:66-67 and Nehemiah 7:69

Ezekiel 25:5 predicts that "I will turn Rabbah into a pasture for camels and Ammon into a resting place for sheep. Then you will know that I am the Lord."

Zechariah 14:15 says that a plague will strike the livestock, including camels, of the enemies of the Lord.

New Testament

In Mark 1:6 and Matthew 3:4 John the Baptist's clothes were made of camel’s hair, and he had a leather belt around his waist.

In Matthew 19:24, Mark 10:25 and Luke 18:25 Jesus says that "Again I tell you, it is easier for a camel to go through the eye of a needle than for someone who is rich to enter the kingdom of God.” (see Question 6 above)

Matthew 23:24 Jesus says "You blind guides! You strain out a gnat but swallow a camel."
