A marine researcher might say, “The conservation of mysticeti species is important for the preservation of marine biodiversity.”
In a discussion about marine tourism, someone might mention, “Observing mysticeti in their natural habitat is a popular activity for eco-tourists.”

75. Pinnipedia

Pinnipedia is a scientific term used to describe a group of marine mammals that includes seals, sea lions, and walruses. These animals are adapted for both land and water and have flippers for swimming.

For example, “Pinnipedia have a layer of blubber to keep them warm in cold waters.”
A marine biologist might say, “The study of pinnipedia helps us understand their behavior and reproductive strategies.”
In a conversation about marine protected areas, someone might mention, “Pinnipedia often use beaches as breeding grounds, so it’s important to protect their habitats.”

76. Sirenian

Sirenians are a group of marine mammals that include manatees and dugongs. The term “sea cow” is often used to refer to these gentle giants due to their large size and herbivorous diet.

For example, a marine biologist might say, “I had the opportunity to study sirenians in their natural habitat.”
In a conversation about endangered species, someone might mention, “The conservation efforts for sea cows have helped increase their population.”
A tourist visiting a coastal area known for manatees might ask, “Where can I go to see sea cows in the wild?”

77. Proboscidea

Proboscidea is the order of animals that includes elephants, mammoths, and mastodons. The term “tuskers” is often used to describe these animals due to their long, protruding tusks.

For instance, a nature documentary might mention, “Tuskers are known for their impressive tusks, which can reach several feet in length.”
In a discussion about prehistoric animals, someone might say, “Mammoths were magnificent tuskers that roamed the Earth thousands of years ago.”
A wildlife enthusiast might share a photo and caption it, “Look at this majestic tusker I spotted on safari!”

78. Artiodactyla

Artiodactyla is an order of animals that includes even-toed ungulates, such as cows, pigs, and deer. The term “cloven-hoofed” is often used to describe these animals, as their hooves are divided into two parts.

For example, a farmer might say, “Cows are cloven-hoofed animals, which means their hooves split into two.”
In a conversation about wildlife, someone might mention, “Deer are artiodactyls with cloven hooves.”
A person discussing animal anatomy might explain, “The cloven-hoofed structure of artiodactyls allows for better weight distribution and stability.”

79. Carnivora

Carnivora is an order of animals that includes carnivorous mammals such as lions, tigers, and bears. The term “meat eaters” is often used to describe these animals due to their diet primarily consisting of meat.

For instance, a zoologist might say, “Lions are members of the Carnivora order, known for their prowess as meat eaters.”
In a discussion about food chains, someone might mention, “Apex predators like tigers play a crucial role as carnivores in maintaining ecosystem balance.”
A wildlife photographer might capture an image of a bear catching a fish and caption it, “Witnessing a true meat eater in action!”

80. Perissodactyla

Perissodactyla is an order of animals that includes odd-toed ungulates, such as horses, rhinoceroses, and tapirs. The term “odd-toed ungulates” is often used to describe these animals, as they have an odd number of toes on each foot.

For example, an equestrian might say, “Horses belong to the Perissodactyla order, characterized by their odd-toed structure.”
In a conversation about endangered species, someone might mention, “The conservation efforts for rhinos are crucial to protect these magnificent odd-toed ungulates.”
A wildlife enthusiast might share a photo of a tapir and caption it, “Check out this unique odd-toed ungulate I spotted in the rainforest!”
