Notes On Endangered Species Table

Many species vital to ensuring that today’s environment will thrive are becoming extinct. If a species is slowly dwindling, and in imminent danger of becoming nonexistent, this species is considered to be endangered. “One in four mammals, one in eight birds, one third of all amphibians and 70% of the world’s assessed plants on the… IUCN Red List are in jeopardy” (IUCN, 2016). According to the International Union for Conservation of Nature, or IUCN, upwards of 16,000 species are threatened with extinction, including both plants and animals (IUCN, 2016). Before becoming endangered, a species will show warning signs, either by starting to lose biological diversity or by losing the habitats for that species to flourish in, or in the worst case, both. The word endangered can sometimes be confused with threatened, extirpated, or extinct. Extirpated refers to the state of a species where its population has died out in a certain area or range, but other populations of said species still exist elsewhere (Olden, Julian D., 2008). When a species is considered threatened, or vulnerable, this refers to the state of the species being susceptible to endangerment and extinction (“Extinction crisis escalates”). So if a species is threatened, the first signs of endangerment come along, which are similar signs to that of a species in danger of becoming threatened, including lack of genetic diversity, or overhunting may be evident. (“Extinction crisis escalates”). When a species is labelled

Habitat: Their habitats are on crops, arable and waste land, gardens. Commonly on footpaths and in

Eastern Massasauga Rattlesnake. The eastern Massasauga is a small thick-bodied venomous rattlesnake, averaging a length of about 2 feet. It is grey or light brown with large chocolate brown botches on its back and sides. The eastern Massasauga rattlesnake has been a candidate species for listing under the Endangered Species Act since 1999 (64 FR 57535 57547, December 25, 1999) (USFWS 2015t).

The adult Great Blue Heron is a blue-gray color. They have a black stripe above their yellow eyes. The stripe extends to the back of the neck turning into a plume of feathers like a ponytail. They have gray, shaggy neck feathers with streaks of white, black, and rust-brown. They

All species are found in North America and tend to be nocturnal, but they inhabit relatively unique niches, which is evident in various minute differences between the species, including fur and nose size. C. townsendii tends to live in evergreen forests that have a moderate climate while C. mexicanus lives in higher, more humid and mountainous habitats. For this reason, C. townsendii has a darker, thicker coat; not only does it act as better natural camouflage, but the coarse, thick hair protects it well from the environment. C. refenisquii is found primarily in the Southwestern United States, but migrates frequently due to the changes in

An environment with a lot of vegetation and their preys is ideal for them. They are perfect hunters with ability to stalk their prey with patience and stealth. They then capture their meals with one strong leap. These animals live in solitary or in territories. One unique thing about them is that the females do not share the same territory with each other. Territories for males usually tend to overlap. The territories are established with scent markings and the size varies extremely. The size ranges from twenty five to thirty square miles for males and five square miles for females (Sunquist & Fiona

The boat-billed herons average height for a full grown adult is about 20 inches. They weight usually about 600g or 1.3 pounds. They have a unique black patch at the base of the hind neck. The animals feathers are a pale grey to white color,they have a chestnut colored belly and black on their side near the hip and ribs. They also have a scoop like bill, so they can scoop up their prey. They have wings that they fly with, as their main source of transportation. The have eyes, ears, and a beak that help them to find their prey, but mostly rely on touch. To protect themselves they raise their dark feathers that are located on their heads.

The birds live in many areas in the United States--around freshwater and seawater. They are birds of prey with a wingspan of 60’’. They are white bodied with a black stripe coming from their eye to their wings which are black also.

The fur on these animals differ from red to brown, sometimes grey. They have long wings. Their black ears point forward, and have wrinkled lips and their tails go beyond the third tail membrane; that is where they got their name. A lot of people say that their tails look like a mouse's. Their Kingdom is the Animalia, their Phylum is Chordate. This animal is a Chordate because they have nerve fibers,

The caterpillars look very intimidating for many reasons. They are a reddish-brown color with orange-brown stripes. It has rows of keen black stripes and two horns on its head. The

The adult females lay eggs stacked on each other which resembles a cactus spine. The larvae feed by burrowing into a pad which can kill their host plant. They have three flights in the southeastern United States which is in late March to May, July to August, and late September to mid-November. They have one host and that is the pricklypear cacti. They are native to Argentina but now found in southeastern United States. They do need some management because they need to be prevented from spreading further.

Hatchlings are 1 inch long while adults are 8-10 inches long. With this breed, the females are dominant in size than the males. Females begin to hatch eggs when they are 6

Since the beginning of life itself, some species have lived and prospered while other species have gone extinct never to be seen again by mankind. Because of this, some would claim that extinction is natural and not significantly problematic to the world that we live in. Others, however, understand that due to climate change, habitat loss, and poaching, more and more species are becoming endangered which leads to a chain reaction that can be devastating to ecosystems. Species such as the Chinook salmon, gorillas, tropical sharks, and polar bears are all directly affected by climate change, species such as northern spotted owls, Sumatran tigers, and lemurs are greatly harmed due to habitat loss, and species such as the sea turtle, Javan rhinoceros, African elephant, and the Red-Fronted Macaw are all affected by poaching driving them all closer and closer to becoming extinct.

The color of their fur is yellowish gold and brown tipped. The color changes during different seasons and climates.
