Slide 1 of 5
The Deep Sea Floor
DEPTH: 4,000 meters
A Hostile Habitat
The deep ocean floor is very tough to live in. Land animals would be crushed instantly because of two massive challenges:
• Total Darkness: No sunlight ever reaches the deep floor.
• Heavy Pressure: The heavy ocean water pushes and squeezes down.
The Pressure Squeeze
Imagine an elephant standing on your thumb! Deep-sea creatures need soft, flexible bodies so they do not break or get squished.

Living Light
BIOLUMINESCENCE
Bio-Glow
Bioluminescence is living light. Since it is pitch black, animals use chemical reactions to glow in the dark!
1. Catching Food
Using a glowing bulb to trick prey into swimming close.
2. Scaring Predators
Using sudden flashes of light to startle big animals and escape.

Pressure Protection
SOFT BODIES
Avoiding the Crush
How do abyssal animals stay safe? They do not have heavy, hard bones like land animals do.
No Air Lungs
No empty, air-filled organs that could collapse. Liquid-filled bodies stay same-sized under pressure.
Jelly Flesh
Squishy, water-rich flesh that does not crack or compress when water squeezes it.
Bendy Bones
Soft cartilage bones (just like the tip of your nose!) that can bend easily without breaking.

Lexile: 650L (SDC Scaffolding)
[¶1] The abyss is the deepest part of the ocean. It is very cold and completely dark because sunlight cannot reach it. The water also has heavy pressure . This means the heavy water squeezes everything like a giant hand. Human lungs would be crushed instantly here. But deep-sea animals have special bodies that do not get squished.
[¶2] Because it is dark, many deep-sea animals make their own light. This is called bioluminescence (bio-glow). They mix natural chemicals inside their bodies to shine. For example, the female Anglerfish has a glowing bulb on her head. She uses this bright light to lure curious little fish closer, then she eats them!
[¶3] Deep-sea fish do not have hard, heavy bones. Instead, their bones are made of soft, bendy cartilage (like the soft stuff in your ears). They also have jelly-like skin. Because their bodies are made of water and soft jelly, the heavy ocean pressure cannot squeeze or crack them.
[¶4] Plants cannot grow in the dark, so there is no sunlight-driven food. Instead, food falls from the top of the ocean. This food is called marine snow . It is made of tiny bits of dead plants and animals that float down like snowflakes. Animals crawl along the muddy ocean floor to eat this snow.
Word Bank & Helper Guide
Pressure: The heavy pushing force of the ocean water.
Bioluminescence: Living light made inside an animal's body.
Cartilage: Soft, flexible bone-like tissue.
Marine Snow: Leftover food drifting down from the surface.

The Threat of Cold
COORDINATES: COLD REGIONS
Why Ice Hurts Cells
Living cells are mostly filled with water. When water freezes, it expands (gets bigger) and makes sharp ice crystals.
• Sharp Spikes: Sharp ice needles poke and tear the soft cells.
• Cell Bursting: Cells break and burst open when frozen.
The Freezing Danger
Because freezing destroys cells, animals must stop ice from forming inside their blood, or keep their core body parts warm!

Biological Armor
ANTIFREEZE PROTEINS
Chemical Shields
Some cold-water fish make special proteins that act like antifreeze shields inside their blood.
1. Blocking Ice
The proteins latch onto tiny ice dots and stop them from growing bigger.
2. Low Freezing
Their blood stays liquid even when the ocean water is below freezing!

Sharing Warmth Inside
How do ducks or wolves stand on ice without freezing their toes? Their legs act like warm-air pipes!
Warm blood coming from the hot heart flows right next to cold blood coming back from icy feet .
The warm pipes heat up the cold pipes before the cold blood can reach the heart. This keeps the core organs hot!

Warm Blood in Freezing Places
Lexile: 670L (SDC Scaffolding)
[¶1] Polar areas are extremely cold. In the winter, the temperature gets much colder than your freezer! This cold weather is very dangerous for living cells. Because animal cells are mostly filled with water, cold weather can freeze them. When water freezes, it expands (gets bigger) and forms sharp, pointy ice crystals . These sharp crystals can poke, tear, and break cells.
[¶2] To stop this damage, some polar fish have developed antifreeze proteins inside their blood. These special proteins latch onto microscopic ice crystals before they grow too big. This stops the crystals from poking and breaking their blood cells. Because of this, their blood stays liquid even in freezing salt water!
[¶3] Warm-blooded polar animals, like wolves, ducks, and penguins, have another clever trick. They use a system called countercurrent exchange to keep their blood warm. This happens inside the blood vessels of their legs. In a normal body, cold legs cool down the whole animal. But in polar animals, warm pipes and cold pipes are twisted tightly together.
[¶4] Warm blood coming down from the heart runs right next to icy blood coming back up from the cold feet. The hot blood warms up the cold blood before it reaches the heart. This keeps the animal's heart and core organs at a safe, warm temperature. It also keeps their feet from losing too much heat to the snow!
Word Bank & Helper Guide
Ice Crystals: Sharp ice needles that can tear open cells.
Antifreeze Proteins: Blood chemicals that block ice crystals from growing.
Vessels: Small tube pipes that carry blood.
Countercurrent: Heat sharing between warm and cold blood vessels.

ENVIRONMENT: DRY DESERTS
Drying Out
Deserts are extremely hot and dry. Without water, bodies dry out. This is called desiccation .
• Evaporation: Sweating and heavy breathing drains water reserves.
• No Rain: Deserts can go months with zero water.

Staying Cool in the Hot Desert
Lexile: 650L (SDC Scaffolding)
[¶1] Deserts are very hot and dry. It rarely rains, and the hot sun shines all day. This extreme heat is dangerous. Without water, an animal's body can suffer from desiccation (drying out). When an animal dries out, its body cannot function properly. To survive, desert species have developed clever tricks to save every drop of moisture.
[¶2] One clever trick is called estivation . This is a long summer sleep. When the desert gets too hot and dry, animals like the African bullfrog go deep under the sand. They make a thick slime cocoon around their skin. This cocoon acts like plastic wrap, keeping existing water locked inside their bodies while they sleep.
[¶3] Other desert animals have redesigned their internal bodies to save water. The kangaroo rat, for example, has super kidneys. These organs recycle water inside its body, letting them excrete very dry waste. They also have cold noses that catch water vapor when they breathe out. This puts moisture back into their throat!
[¶4] Kangaroo rats also make metabolic water inside their cells. They do not need to drink liquid water pools. Instead, when they digest dry seeds, their cells perform a chemical reaction to split and blend molecules into fresh, clean water!
Word Bank & Helper Guide
Desiccation: Drying out completely due to heat.
Estivation: A deep summer sleep underground.
Metabolic Water: Water made inside cells from dry food.
Recycle: Reusing water instead of wasting it.
