These animals are diverse, aquatic, and primarily photosynthetic organisms belonging to the kingdom Protista, ranging from microscopic single-celled forms to large multicellular forms like kelp (seaweed). They are not true plants, lacking specialized structures like roots and leaves, but they form the base of many aquatic food webs and produce a significant portion of the Earth's oxygen. These animals can be green, brown, red, or golden, depending on their pigments, and are found in nearly all aquatic environments, including saltwater, freshwater, and brackish water.
Algae.
These animals are small, soft-bodied insects, often pale in color, that live in social colonies and feed on wood and other materials containing cellulose. They have three body segments, six legs, and straight, beaded antennae. These animals are distinct from ants by their broad waist (vs. constricted in ants) and their two pairs of equal-length wings. While they play a role in decomposing wood in nature, their consumption of cellulose can cause significant structural damage to homes and other wooden structures
Termite.
A large, stout, venomous lizard with short legs, found in the deserts of the southwestern U.S. and northwestern Mexico, characterized by black, beaded skin with bright yellow, orange, or pink patterns.
Gila Monster.
You go at red, but stop at green. What am I?
A watermelon. You eat the red part, and you stop eating at the green part.
What tastes better than it smells?
The tongue.
These animals are cube-shaped, translucent, venomous marine animals found in tropical and coastal waters worldwide, named for their distinctive box-like bells and armed with potent stinging tentacles. Known as sea wasps, they are active predators that hunt fish and crustaceans using a relatively sophisticated nervous system and a complex set of 24 eyes. While most species' stings are painful but not lethal, a few species possess venom so deadly that it can kill an adult human in minutes.
Box Jellyfish.
These animals are large, winged insects characterized by two pairs of membranous wings, an elongated, segmented abdomen, and large, compound eyes that cover most of their heads. They are known for their exceptional flight abilities, including hovering and flying backward, and are effective aerial predators of other insects. Found on every continent except Antarctica, dragonflies are also recognized for their diverse and often vibrant colors and can range in size from less than an inch to over five inches long.
Dragonfly.
These animals are small to medium-sized, primarily nocturnal reptiles with unique adhesive toe pads that allow them to climb surfaces, and many species can make vocalizations like chirps or clicks.
Gecko.
I’m a god, a planet, and I measure heat. What am I?
Mercury.
No matter how little or how much you use me, you change me every month. What am I?
A calendar.
These animals are flat, bottom-dwelling fish characterized by their compressed bodies and two eyes on one side of their heads (the "eyed" side), which allows them to blend into the seafloor to ambush prey. Their colored side is typically brown, gray, or olive, featuring spots that provide camouflage, while their underside is white. These animals are active predators that feed on shrimp, crabs, and other fish, and they spend much of their lives in coastal waters and estuaries.
Flounder.
These animals have stout, hairy bodies, feathery or thread-like antennae, and wings covered in dust-like scales. They vary greatly in size, are typically nocturnal, and rest with their wings flat or wrapped around their bodies.
Moth.
These solitary creatures have stout bodies, short legs with sharp digging claws, long snouts, and poor eyesight, but a strong sense of smell for finding insects and invertebrates to eat. While most dig into the ground to escape predators, some species, like the three-banded armadillo, can roll into a protective ball.
Armadillo.
A seed with three letters in my name. Take away two and I still sound the same. What am I?
A pea.
What do you see once in June, twice in November, and not at all in May?
The letter "e."
These animals are large, gray, herbivorous aquatic mammals, often referred to as "sea cows" due to their diet of aquatic plants. They have a stout, tapered body, two flippers, and a paddle-shaped tail, which they use for swimming. These gentle giants are known for their slow movement, though they can swim quickly for short bursts. They must surface to breathe air but can hold their breath for extended periods. These animals are closely related to elephants and have rough, wrinkled skin covered in sparse, sensitive hairs that help them sense their surroundings.
Manatee.
These animals are primitive, omnivorous insects that can be found globally, though they prefer warm, humid environments and are primarily nocturnal scavengers. They possess chewing mouthparts, a hardened exoskeleton, and three life stages: egg, nymph, and adult. Their specific characteristics, including size, color, and the presence and development of wings.
Cockroaches.
These animals are small, stocky, and toad-like reptiles found in North America, known for their flat, camouflaged bodies, spiny scales, and a crown of distinctive horns on their heads. They possess a unique defense mechanism of squirting blood from their eyes to deter predators like coyotes and wolves, and can inflate their bodies to appear larger. Primarily insectivores, they specialize in eating ants and other insects, and their coloration allows them to blend in with their desert or prairie habitats.
Horned Lizard.
You can touch me, you can break me and you should win me if you want to be mine. What am I?
Heart.
What has 13 hearts but no other organs?
A deck of cards.
These animals are known for their ability to rapidly inflate their bodies with water or air to deter predators, and most are poisonous, containing the potent toxin tetrodotoxin in their organs and skin. These fish have scaleless, often spiky skin and a distinctive beak formed by four fused teeth used to crush shellfish and other hard-shelled prey. They are found in tropical and subtropical waters worldwide, inhabiting coral reefs and both saltwater and freshwater environments.
Pufferfish.
These animals are small, wingless insects, typically 1-8mm long, with reddish-brown bodies, piercing-sucking mouthparts, and powerful hind legs for jumping. Their bodies are flattened from side to side, and they have spines to help them stay on a host. These external parasites feed on the blood of mammals and birds, and have a four-stage life cycle (egg, larva, pupa, adult). They are parasitic, which means they rely on a host, and their bites can cause itching and transmit diseases.
Fleas.
It uses its long, yellow, forked tongue to smell its surroundings and locate prey, which it ambushes using sharp claws and serrated teeth. Its bite is venomous, causing blood loss and rapid. The world's largest lizard, growing up to 10 feet long and weighing over 300 pounds, with a tough, scaly, dark gray or brownish hide, powerful, muscular legs and tail, and a flat head with a rounded snout.
Komodo Dragon.
