1. Llama
Llamas (Lama glama), members of the Camelidae family, are domesticated animals originally from the Andes Mountains in South America. Standing 5.5–6 feet (1.7–1.8 meters) tall at the head and weighing 250–450 pounds (113–204 kilograms), they are built for high-altitude environments with their thick wool coats and padded feet. Llamas come in various colors, including white, brown, gray, and black, often with striking patterns.
Herbivorous, llamas feed on grasses and shrubs, using their three-chambered stomachs to efficiently process tough vegetation. These social herd animals communicate through vocalizations and body language, with a calm demeanor but a tendency to spit when irritated. Females give birth to a single cria after an 11-month gestation, and herds often work together to protect young.

2. Lobster
Lobsters, marine crustaceans from the order Decapoda, inhabit coastal waters, rocky crevices, and reefs in temperate and tropical oceans worldwide. Depending on the species, they range from 8–24 inches (20–60 cm) in length and weigh 1–15 pounds (0.5–7 kilograms), with some reaching even larger sizes. Lobsters come in a variety of colors, including greenish-brown, blue, and red, the latter appearing after cooking.
Omnivorous scavengers, lobsters feed on fish, mollusks, algae, and organic debris, contributing to ecosystem balance. Solitary and nocturnal, they use their long antennae to sense surroundings and hunt at night. Females carry thousands of eggs under their tails, releasing planktonic larvae that drift before settling on the ocean floor. Growth requires molting their hard exoskeleton, a vulnerable period.

90. Leech
Leeches, members of subclass Hirudinea within class Clitellata, inhabit freshwater, marine, and terrestrial environments worldwide. They vary in size from 0.2 to 16 inches, with soft, segmented bodies and suckers at both ends for attachment and movement. Their coloration ranges from black and brown to green and striped patterns. Parasitic leeches feed on blood, using sharp jaws to pierce the skin and secrete anticoagulants to ensure smooth feeding.
Their hosts include fish, amphibians, and mammals, while non-parasitic species consume detritus, insects, or small invertebrates. Leeches are solitary, actively swimming or crawling to find food or hosts by detecting movement and chemical cues. Hermaphroditic by nature, leeches exchange sperm to reproduce, laying fertilized eggs in cocoons attached to vegetation or submerged surfaces. Some species carry their cocoons or young until they are self-sufficient.

91. Limpet
Limpets, marine gastropods from families like Patellidae and Lottidae, inhabit rocky intertidal zones worldwide. Measuring 0.4–2 inches long, they have cone-shaped shells that protect against predators and water loss. Their muscular foot enables a firm grip on rocks, even in strong waves. Shell colors range from gray to greenish, blending with their surroundings.
Limpets feed on algae, scraping it from surfaces with their radula, a ribbon-like structure with tiny teeth. They are most active during high tide, grazing and leaving characteristic marks on rocks. During low tide, they return to “home scars,” ensuring safety and moisture retention.
Reproduction occurs through broadcast spawning, with eggs and sperm released into the water. Limpets lack parental care, and larvae eventually settle on rocks to mature. Some species transition from male to female during their lifespan.

92. Lamprey
Lampreys, members of the jawless fish class Agnatha, are ancient vertebrates found in freshwater rivers and streams worldwide. Depending on the species, they range from 6 to 40 inches in length and weigh 0.1 to 5 pounds. Their elongated, eel-like bodies lack paired fins, and parasitic species have circular, jawless mouths lined with sharp, tooth-like structures for attaching to hosts.
Parasitic lampreys feed on fish blood and bodily fluids, while non-parasitic species do not feed as adults, relying on energy reserves from their larval stage. They are solitary except during spawning, when they migrate to gravel-bottom streams to construct nests, or redds. Females lay thousands of eggs, fertilized by males, with no parental care. Hatchlings, called ammocoetes, burrow into sediment and filter-feed for years before transforming into adults.
