Match each mouth adaptation to its purpose.

Duckbill Jaw

Feeds throughout the water

Sword on front upper jaw

"Vacuums" up food off the bottom; eats aquatic insects, vegetation

Terminal (at the end of the snout)

Feeds on prey it sees above it or at surface of water ; small fish, aquatic insects

No teeth

Feeds on other (and bigger) fish

Strong jaws and well-developed teeth

Grasps its prey

Very Large mouth

spears food

Very small mouth

Eats Plankton

Angled upward/longer lower jaw

Swallow prey whole, shrimp, crabs, small fish

Sucker - Shaped

Eats small food like Zooplankton

What do Terminal, under the snout with long upper jaw, Ventral, and jaws with barbells (feelers) have in common?

They all only eat plants

They all eat small fish

They all eat larger fish

They all feed off of the bottom

Match each scale adaptation to its purpose.

Bony armored scales

Used for protection; speed not needed to catch food

Large scales

Fish more streamlined and fast-moving to catch prey

Small or non-existent scales

Protection

Match each eye adaptation to its purpose.

Eyes on same side of head

Uses eyes to see food

Eyes on top of head

Likely feeds off the bottom and relies on barbells/whiskers to detect food

Small eyes

Lies flat on bottom of water

Large eyes

sits on bottom and looks up

Match each body adaptation to its purpose.

Mimicry

Protection from predators

Slower Metabolism

Can look like a plant or a venomous organism to avoid predators

Electric Organs

Attracts mates or prey in darker waters

Poison skin 

Navigation, prey location, and communication. Some can produce strong electric fields to stun potential prey.

Efficient Enzymes

Can poison predators, so predators stay away

Extra fat in cell membrane

Help speed up chemical reactions in the body in very cold waters

Bioluminescence

Less energy needed in very cold waters

Non- Venomous and Venomous Spines

Insulation to prevent cells from freezing

Match the body shape to the type of swimmer.

Horse shaped

Thin side to side, shorter, disk shaped

Fusiform, torpedo shaped body

Oval, Long body

Round Body

hump backed

Oval, very Long, eel like, body

Box Shaped

Horizontal disk, flat from top to bottom

Triangle shaped

Rounder back, flat belly

Slow swimmer

Rests on the bottom

Open water swimmer

Fast swimmer/stable in fast water/Agile

Match each color adaptation to its purpose.

Light colored belly

Swims in open water

Dark on top

Hides in weeds for protection or to ambush prey

Uniform, no markings

Hides in rocks or on the bottom

Mottled (a lot of pattern)

Less visible to predators above it, predators have difficulty seeing it from above

Horizontal or Vertical Stripes

Less visible to predators below it, predators have difficulty seeing it from below

Match each reproductive adaptation to its purpose.

Egg deposited in nests

hidden from predators

Live bearers

Protected by adults

Egg deposited in bottom

Dispersed in high numbers

Floating eggs

Stable until hatching

Eggs attached to vegetation or rocks

Few babies, but high survival rate

Match each caudal fin adaptation to its purpose.

Lunate/Concave caudal fin

Strong, fast continuous swimmer

Rounded lobed caudal fin

able to swim in and around cracks and crevices.

Truncated/Straight caudal fin

Fastest swimming fish and maintain a rapid speed for long durations

Continuous caudal fin with dorsal and pelvic fins

Strong, but slow, swimmers and can do quick burst of speed

Large Torked or Tri-lobe caudal fin

Strong, slow swimmers

Double truncated caudal fin

Slow swimmer able to make sharp turns and to move in short bursts very fast from a standstill.

Match each other fin adaptation to its purpose.

Finlets

For protection or to stiffen fins for swimming

Strong pectoral fins

Bottom Dwellers

Dorsal fin acts like a lure

Open water swimmers

Anal fin attached 2/3 length of body and fused with caudal fin

Able to provide an upward lift, can jump out of water

Spines on fins

Gives superior control in the water, moving forward and backward with a minimum of wasted energy.

Large Pelvic fins

To attract prey

Small pelvic fins

a cooling and heating system after or before high-speed bursts.

High dorsal fin that covers most of back

To improve swimming speed

Wing-like pectoral fins

To walk along the bottom of the ocean
