Endangered Animals That Need Our Rescue

Axolotl

Tuesday, August 23rd, 2011

There are many types of animals that are critically endangered. Axolotl will be a tadpole all their life even if they become big. They grow in a very unique way, because they retain their larval features for the rest of their lives. Unlike the tadpoles that become frogs as they grow up, the axolotl, though it is amphibious, stays in the water as it grows and remains a tadpole for the rest of its life. The Axolotl is an endangered species that can only be found in Xochimilco Lake, near Mexico City. They have exposed gills stretching behind their heads where they breathe.

Endangered

The Axolotl is unfortunately on the brink of extinction. The axolotl is a top predator in the lake. However, due to the introduction of other predators in this area, competition is threatening the axolotl. This is why it is considered an endangered species. The axolotl is also exported as pets. Many people think that axolotl is a very cool pet to have. They capture and export this animal, which is also another reason why this animal is considered an endangered species.

Protective measures

The Mexican Wildlife Service has been making actions to protect and preserve the axolotl. They work with international endangered species organizations to bring an increase in the numbers of this animal. There have been many progresses with the actions being done by the Mexican Wildlife Service. They are educating people in the area about the threats that poaching and habitat destruction have on these animals.

Human Acts

Humans made the Xochimilco Lake very dirty. Sewages and dirty water from different towns are being dumped into this lake. Human beings are destroying the natural habitat of the axolotl. This is one of the main reasons for the endangerment of this species. The axolotl is an endangered species also because people put different fishes in the lake. This introduction of new species in the lake disrupts the balance of the ecosystem. Predation and competition from the introduced species causes the endangerment of the axolotl. Fortunately, axolotl are now protected. People are not allowed to catch them for export or for pets anymore.

Aztec Legend

The axolotl is an Aztec legend. Some people calls it the “water monster” while other people calls it the “Mexican Walking Fish.” Despite of the urbanization of the towns in Mexico, axolotl has fortunately survived. However, it is now an endangered species. Scientist is now acting to save the axolotl from extinction. They predict that this animal may be completely extinct in about 5 years. If the axolotl is extinct Mexico will not just lose their biodiversity but also a part of their culture.

Poison Dart Frogs

Friday, May 13th, 2011

Poison Dart Frogs remain on the world’s most critically endangered list of animals. They are normally found in places such as Central and South America’s rainforests and as their name suggests, they contain certain levels of toxicity. They are able to release toxins from their skin. However, thanks to their noticeable appearance and bright colors, one can easily identify and keep distance from the frogs. They come in all sorts of color combinations. The reason Poison Dart Frogs remain as one of the most endangered animals so no different than other tropical animals.  The causes are mainly climate change, habitat loss, use of fertilizers and pesticides, or acid rain and attention needs to be directed on saving these frogs so that the life cycle doesn’t get disrupted.

There are about less than 200 known species of poison frogs today so you can imagine how much of an impact the environment is having on these amphibians. In their adult state, they reach a size of only 2-5cm in length and weigh only a few grams. So while they can be very dangerous, their size would also make them seem vulnerable, especially when it comes to effects of pollution and climate change. Their size would be a good reason why they are near extinction.

Rescuing these dart frogs is important because they control the population of various pests. As you can imagine with the life cycle, if not enough of them are available to take on this task, we would have problems of overpopulation or under population. This is likely a problem that spawns with species being extinct so while we should make an effort to protect Poison Dart Frogs, animals in the rainforest that remain crucially endangered should also be protected!
