Answers:

1. This species is considered to be depleted in at least 50% of many parts of its range (Philippines, PNG, India, Indonesia, Madagascar), and is considered overexploited in the South Pacific, and the majority if its range. For example, there has been a more than 60% decline over the past 30 years in at least one region (New Caledonia). In East Africa, it is heavily exploited, but the statistics are unreliable. No data from western Australia is available. Depletion refers to commercially unviable, and estimated to represent an approximately 90% loss or greater. In areas where it is considered overexploited, populations are difficult to estimate based on regional and local fishing effort, but harvests have declined and based on traditional fisheries definitions, overexploited is estimated to be at least 30% above maximum.

2. It is characterized by it's large size, warm colors, and pointed, star-shaped teats covering the entire body, grouped in rows of 2 and 3

3. The steps they need to take is to stop overfishing them (scuba diving) because they are losing too much of them and also they have a medium-high market value

4. Yes, they are considered a keystone specie. They are found along slopes and passes within reef zones and along outer reef flats to depths of 35 m, but is more common in waters from 10-20 m.

Rainbow Parrotfish - These fish are unique because of their unusual mouthparts. Their teeth are fused together, which creates a parrot-like beak. They are declining due to destruction of its mangrove habitat, as well as overfishing. These parrotfish are considered a keystone species because they eat seaweed/macroalgae that would otherwise smother corals.

By Carter M,
Australian sea lions have been endangered since 2008. There are 81 recorded breeding sites, but there are more than 100 pups produced at only seven of those sites. Current estimates suggest there is a total population of 3,204 Australian sea lions to date.

What makes the species unique?
Australian sea lion feces have nutrient-rich poop that is important for regions along Australia's South West coastal ecosystems.

Why are they in decline?
Australian sea lion hunting in the 19th century led to colonies of these animals being wiped out. Sea lions are also sensitive to changes in temperature, especially due to climate change.

What steps can be taken to save them?
The only real way to prevent further deaths, is to not allow these sea lions to go beyond a specified area from the shore so fishers do not kill them with nets or hunting weapons.

Are they known as a keystone species?
Yes, the Australian sea lions are a keystone species, in part because of their nutrient-rich poop, and otherwise because they regulate much of the marine ecosystem along the coastal waters, feeding on the multitude of small aquatic organisms.

Axolotls in Lake Chalco in the Valley of Mexico.

2022-11-08 18:09:11 UTC

Animal: Axolotl <3
What makes the ✨unique✨? Due to a rare condition called 'neoteny', they retain most of their larval features into adulthood, so they have all the features of a tadpole
(Source: https://www.bluereefaquarium.co.uk › blog › education)
Why are they in decline? Axolotls are in decline due to over fishing :(
(source: https://www.bluereefaquarium.co.uk › blog › education)
What steps are being taken to save Axolotls? through the creation of ajolotarios, or axolotl habitats, where the amphibians can reproduce and grow in a clean and safe environment.

Lethariella togashii is a very rare species of fungi, but no detailed assessments of population size and its decline exist. One subpopulation out of six (ca 17%) is considered extinct. Further decline by the destruction of habitats (montane coniferous forests) due to human activities, forest fires and tree cutting, is possible.

My animal is the Snow Leopard.

Some of its threats to it's population include residential and commercial development, tourism, climate change, invasive species and disease, human intrusions and more. Hunting to be more specific.

Well first it's an awesome leopard which is definitely a reason it's unique but also they are the top predator in their ecosystems, also seems to maybe affect water and if they are doing good then so does a lot of other species and the largest freshwater reservoir on our planet.

Some efforts to help not cause it to die out are site and area protection and surveillance, habitat restoration and education

Snow leopards are indeed considered a keystone species

Brazil - Brazilian Merganser

655307 — 2022-11-08 18:20:55 UTC

1. The Brazilian Mergansers species is declining because they are very sensitive to habitat degradation and loss primarily due to human actions. There are possibly fewer than 250 birds left.
2. They are unique because of its long, sharp-edged beak that has a great number of teeth-looking edges.
3. A Brazilian-based survival breeding program. "The hope is the birds bred at the facility could ultimately be the foundation for a future wild release project, which would help replenish the declining population."
4. They are not known as a keystone species.

Glaucous Macaw Anodorhynchus glaucus is listed as Critically Endangered under criteria D.According to the International Union for Conservation of Nature (IUCN), the Glaucous Macaw is on the Red List as “Critically Endangered — Possibly Extinct.” The IUCN believes that there are fewer than 20 living in the wild, and the loss of the species was caused by depletion of habitat through agriculture and housing.

It has a long tail and a large bill. It has a yellow, bare eye ring and half moon-shaped lappets bordering the mandible, The bird's disappearance probably is linked to trapping of live adults for the wild bird trade and the wholesale felling of the yatay palm, Butia yatay, the nuts of which appear to have constituted its main food.

steps to help them are to stop bird trade and by breading them in captivity.

All surgeonfish have very small scales giving them an unusual appearance. Many are able to change their coloration in intensity and color according to their mood. The surgeonfish is in decline because of the slow degradation of coral in the surrounding areas making it to where they have no places to live. The only steps that can be taken to save surgeonfish is to preserve coral reefs and make sure they do not become extinct because several types of fish would slowly follow after. They are not a keystone species.

Iran and the Asiatic cheetah

2022-11-08 18:23:27 UTC

The Asiatic cheetah is critically endangered, steps we can take to protect the cheetah's is to guard them such as they are already doing with 125 game guards protecting the cheetah's range. they are in decline because of prey and habit loss, car collisions. they are unique because they are important to culture and has became a symbol to country's conversation efforts. they are considered a keystone species in the India grassland

CHILEAN FLAMINGOS

One of the biggest threats to flamingo populations in the wild is lithium mining.

Smaller and paler than most of its relatives and is more accustomed to the temperate climate than Caribbean flamingos

One way to help flamingos is to buy lithium-containing electronic devices only when necessary

They are second consumers, if the went extinct more brine shrimp would populate the region. They control populations from becoming over populated by eating them.

The Euphrates softshell turtles are an important predator in aquatic systems. It's population is declining due to habitat loss and alterations, but to lesser extent being killed by fishermen and pollution. This species must be monitored of it's population size and trends, and creating nesting and breeding grounds is very important.

Ocelots are deeply endangered because their habitats have been cleared for farming and housing. One of their unique qualities are it's spotted fur which helps it hide in plain site. To help we needs to help give Ocelots a healthy environment to live in. They are a keystone species as they keep small bird and mammal levels in check

The Apollo Butterfly is endangered because of habitat destruction, air pollution affecting the insect's food plants, and butterfly collectors. Apollo Butterfly's are known for their bright, neat appearance with two pairs of white wings and a white hairy body. Things that we can do in order to save this endangered species are less air pollution, and making laws to prevent butterfly collectors from taking them. Apollo Butterfly's prefers hills and flowery alpine meadows and pastures of the continental European mountains, in Spain, Scandinavia and Central Europe, in the Balkans up to northern Greece and in the Alps between Italy and France.

1. This species is unique because it has a blue color and significant marks special to each butterfly.
2. They are endangered due to landscape-scale threats from pesticides and the development of climate change.
3. Plant more "native" plants in their environment, space them out, live with some pest presence but wash most pesticides away, limit contact with their habitat, reduce oil/gas usage.
4. They are a predatory species.

Striped Hyaena

Striped hyenas have become endangered through habitat loss.

Striped hyenas are a bit smaller than spotted and brow hyenas and are the least studied. They have a broad head with dark eyes, a thick muzzle, and large, pointed ears.

Work with communities to help them construct bomas - livestock enclosures that protect livestock from predators and ultimately mitigates human-wildlife conflict

European Mink. Its water repellent coat and the prevalence mink has in fashion for being such a small animal is what makes it unique. Habitat loss, over-hunting, competition with American mink(was introduced to europe), and decline of crayfish population(their food). Prevent over hunting and fishing of the Euro-Mink and Crayfish, kill all the American Minks, and protect their habitat. Its not a keystone species but its important due to the fact is both predator and prey.

The Japanese Paradise Flycatcher is a medium-sized bird native to southeastern Asia. They have exceptionally long tails, and also bread and live within deciduous rainforests, and are therefore threatened by logging and wood harvesting companies and the need to expand farmland and annual & perennial non-timber crops. Loss of habitat has also happened due to degradation in winter seasons. Conservation sites of there habitats have been identified and are being preserved.

African wild dog - Sub Sahara (sierra)

2022-11-08 21:42:51 UTC

https://conservationtravelafrica.org/blog/help-protect-african-wild-dogs/

Also called the painted dog or Cape hunting dog. Wild dogs are social and gather in packs of around ten individuals, but some packs number more than 40. They are opportunistic predators that hunt medium-sized ruminants, such as gazelles. In a sprint, African wild dogs can reach speeds of more than 44 miles per hour.

The causes of African wild dogs’ decline are reasonably well understood and include:

Extreme sensitivity to habitat fragmentation as a consequence of wide‑ranging behaviour;
Conflict with livestock and game farmers;
Accidental killings by snares and road accidents, and
Rampant spread of infectious diseases.

https://www.awf.org/wildlife-conservation/african-wild-dog

"Mitigate human-wildlife conflict:

Retaliation is the primary reason for African wild dog killings. We work with communities to help them construct bomas—livestock enclosures—that protect livestock from predators. We also monitor wild dog movements to anticipate and prevent a potential conflict with humans.

Engage local communities:

African Wildlife Foundation educates community members on protecting their local wildlife and equips them to do so. In the Samburu landscape, AWF, with funding from the U.S. Agency for International Development and the Dutch government employed 12 scouts from five neighboring communities. These scouts monitor the wild dogs, learning their movements and alerting herders when wild dogs are present. By providing access to new employment, AWF is able to weave conservation and economic opportunity together to incentivize wild dog protection."

Egyptian Vulture

2022-11-08 21:44:19 UTC

Known as the pharaohs chicken. They are migratory birds. Egyptian vultures face threats like poisoning poaching and electrocution and human disturbance. Vultures as a species help define the ecosystem. They dispose of dead carcasses thereby stopping the spread of disease. Without them, there will be the increase of disease across the areas. Feeding stations are being implemented for the species. As well as being observed from afar to watch what they are eating to keep them safe, since they'd eat just about anything.
