TEXT 1 - OCTOPUSES
Octopuses are fascinating creatures with a number of unique characteristics that set them
apart from other animals. Here are some of their main characteristics and interesting
curiosities:
1. Body structure: Octopuses have eight arms, each lined with suckers that they use for
grasping and manipulating objects. Their body is soft and boneless, allowing them to
squeeze through small spaces and hide in tight crevices.
2. Intelligence: Octopuses are highly intelligent and are known for their problem-solving
abilities. They can learn from experience and even exhibit playful behavior.
3. Camouflage: Octopuses are masters of camouflage and can change the color and
texture of their skin to blend in with their surroundings. They use this ability to avoid
predators and to sneak up on prey.
4. Escape artists: Octopuses are also skilled escape artists and can use their powerful
arms to open jars and manipulate objects to help them escape from aquariums.
5. Short lifespan: Most octopuses only live for a few years, with some species living as
little as six months. This is because they grow quickly and use up their energy
reserves at a faster rate than other animals.
6. Invertebrates: Octopuses are part of the phylum Mollusca, which also includes clams,
snails, and squid. They are classified as invertebrates because they do not have a
backbone or internal skeleton.
7. Ink defense mechanism: Octopuses can release a cloud of ink as a defense
mechanism to confuse predators and make a quick escape.
8. Three hearts: Octopuses have three hearts – one central heart that pumps blood
through the body and two branchial hearts that pump blood through the gills.
9. Solitary creatures: Octopuses are typically solitary creatures and only come together
to mate.
10. Physical flexibility: Octopuses are incredibly flexible creatures and can contort their
bodies in ways that most other animals cannot.

TEXT 2 - SEAHORSES
Seahorses are a group of small marine fish that are known for their unique appearance and
interesting behaviors. Here are some of their main physical features and fascinating aspects:
1. Body structure: Seahorses have a unique body structure that sets them apart from
other fish. They have a long, thin snout and a curved neck that allows them to move
their eyes independently of each other. They also have a prehensile tail that they can
use to anchor themselves to objects in their environment.
2. Coloration: Seahorses are often brightly colored and have intricate patterns on their
bodies. They use their coloration as a form of camouflage to blend in with their
surroundings.
3. Habitat: Seahorses are found in shallow, tropical and temperate waters around the
world. They prefer to live in areas with plenty of vegetation and other objects to
anchor themselves to.
4. Unique swimming style: Unlike other fish, seahorses swim upright and use their
dorsal fin to move forward. They are not strong swimmers and are often carried by
ocean currents.
5. Male pregnancy: One of the most unique aspects of seahorse biology is that the
males are the ones who become pregnant and give birth to their young. Females
deposit their eggs in a pouch on the male's abdomen, where they are fertilized and
incubated until they hatch.
6. Courtship behavior: Seahorses have elaborate courtship behaviors that involve
dancing, changing colors, and touching each other with their snouts. They also
engage in "holding hands" with their tails to reinforce their bond.
7. Threats: Seahorses are threatened by a number of factors, including habitat loss,
pollution, and overfishing. They are also heavily targeted for use in traditional
medicines and as curios.
8. Conservation efforts: Because of their unique biology and threatened status,
seahorses are the focus of a number of conservation efforts around the world. Many
countries have placed limits on the harvest and trade of seahorses, and some have
established protected areas to safeguard their habitats.
9. Size: Seahorses are relatively small fish, with most species measuring between 2
and 8 inches in length. The smallest seahorse species, the pygmy seahorse, can be
as tiny as half an inch.
10. Diet: Seahorses are carnivorous and primarily eat small crustaceans and plankton.
They use their long snouts to suck in their prey, which they swallow whole.

TEXT 3 - STARFISH
Starfish, also known as sea stars, are fascinating creatures that can be found in a variety of
marine environments. They are not actually fish, but rather echinoderms, which are a group
of marine animals that also includes sea urchins and sand dollars. One of the most
distinctive features of starfish is their five-point radial symmetry, which means that their body
is arranged in five equal parts that radiate out from a central point.
Starfish come in a variety of colors and sizes, with some species measuring just a few
inches across and others reaching over three feet in diameter. Most starfish have a rough or
spiny texture on their upper surface, which helps to protect them from predators. They also
have tube feet that are used for locomotion and for capturing prey.
Starfish are carnivores, and they primarily feed on mollusks such as clams and oysters.
They use their tube feet to pry open the shells of their prey and then push their stomachs out
through their mouth and into the shell. They then digest the prey inside the shell and retract
their stomachs back into their bodies.
Starfish have the ability to regenerate lost limbs, and in some cases, they can even
regenerate an entire body from just a single arm. This makes them unique among animals,
as most creatures do not have this level of regenerative ability. In addition to their
regenerative powers, starfish also have the ability to change their skin color in response to
their environment, which helps them to blend in with their surroundings and avoid predators.
Despite their unique abilities, starfish face a number of threats in the wild. Pollution,
overfishing, and habitat destruction are all major threats to their survival. However, there are
conservation efforts underway to protect these fascinating creatures and their habitats.

TEXT 4 - FLYING FISH
Flying fish are a unique species of fish found in oceans around the world. They are known
for their ability to launch themselves out of the water and glide through the air for distances
of up to several hundred feet. This adaptation allows them to escape predators that hunt
them from below, such as tuna and marlin.
Flying fish are usually small, measuring between 7 and 12 inches in length. They have long,
slender bodies and large pectoral fins that they use to glide through the air. They also have a
streamlined shape that helps them to move quickly through the water. Their scales are
iridescent and can appear to change color depending on the angle of the light.
There are over 60 species of flying fish, and they are found in both warm and cold waters.
They are typically found in schools near the surface of the water, where they feed on
plankton and small crustaceans. When threatened, they launch themselves out of the water
and can reach speeds of up to 37 miles per hour.
The ability to fly through the air is not unique to flying fish. Other marine animals, such as
flying squid and flying gurnards, have also developed the ability to glide through the air to
escape predators. However, flying fish are among the most skilled and efficient gliders in the
animal kingdom.
Despite their impressive aerial abilities, flying fish are still vulnerable to a number of threats.
Overfishing, pollution, and climate change are all major threats to their populations. Efforts
are underway to protect these unique and fascinating creatures and their habitats.
