그동안 많은 애완동물들을 키우며 인터넷으로 찾아가며 공부했던게 기억나서 키워본 아이들을 정리해보려한다.
우파루파는 멕시코의 상징이며 세계적으로 사랑받는 애완동물이며 생존의 절대 강자로 다리, 꼬리, 심지어 심장의 일부가 잘려도 재생된다한다.
2008년에 우파루파를 키우게 되었다. 우파루파의 먹이인 실지렁이는 피비린내와 이상한 비주얼 때문에 적응하는데 시간이 필요했다. 하지만 곧 나는 실지렁이에 적응을 했고, 실지렁이 먹이주는걸 안 무서워하는 내가 먹이주는 담당이 되었다. 우파루파를 열심히 키우다보니 알을 낳았다. 2009년 1월 1일 할머니 집에 가는동안 부화한 새끼들을 부화통으로 옮기지 못해서 혹시 부화하고 나온 새끼들이 죽을까봐 어항을 싸들고 할머니 집에 갔던게 기억 난다.
In the meantime, I remember that I had been studying with lots of pets and surfing on the internet.
Axolotl, it is a symbol of Mexico, a world-loved pet, and the absolutely amazing at survival. It can survive when its leg, tail, or even parts of the heart are cut.
In 2008, I started to grow up an axolotl. The earthworm, a prey of the axolotl, First, I needed time to adjust on the earthworms because of the bloody and strange visuals. But soon I became accustomed to the earthworm, and I became the feeder because I was the only one who wasn't afraid of earthworms. After a few months, Alxotil gave birth to eggs. January 1, 2009, New Year, I remember that our family carried their cage to prevent eggs from dying.
The axolotl, Ambystoma mexicanum, also known as the Mexican walking fish, is a neotenic salamander related to the tiger salamander. Although the axolotl is colloquially known as a "walking fish", it is not a fish, but an amphibian. The species was originally found in several lakes, such as Lake Xochimilco underlying Mexico City. Axolotls are unusual among amphibians in that they reach adulthood without undergoing metamorphosis. Instead of developing lungs and taking to the land, adults remain aquatic and gilled. Axolotls should not be confused with waterdogs, the larval stage of the closely related tiger salamanders, which are widespread in much of North America and occasionally become neotenic. Neither should they be confused with mudpuppies (Necturus spp.), fully aquatic salamanders that are not closely related to the axolotl but bear a superficial resemblance. As of 2010, wild axolotls were near extinction due to urbanization in Mexico City and consequent water pollution, as well as the introduction of invasive species such as tilapia and perch. They are currently listed by CITES as an endangered species and by IUCN as critically endangered in the wild, with a decreasing population. Axolotls are used extensively in scientific research due to their ability to regenerate limbs. Axolotls were also sold as food in Mexican markets and were a staple in the Aztec diet.[9] Surveys in 1998, 2003, and 2008 found 6,000, 1,000, and 100 axolotls per square kilometre in its Lake Xochimilco habitat, respectively. A four-month-long search in 2013, however, turned up no surviving individuals in the wild. Just a month later, two wild ones were spotted in a network of canals leading from Xochimilco. The city is currently working on conserving axolotls by building "axolotl shelters" and conserving remaining and potential habitats for the salamanders. Description A captive axolotl A sexually mature adult axolotl, at age 18–24 months, ranges in length from 15 to 45 cm (6 to 18 in), although a size close to 23 cm (9 in) is most common and greater than 30 cm (12 in) is rare. Axolotls possess features typical of salamander larvae, including external gills and a caudal fin extending from behind the head to the vent.[citation needed] Their heads are wide, and their eyes are lidless. Their limbs are underdeveloped and possess long, thin digits. Males are identified by their swollen cloacae lined with papillae, while females are noticeable for their wider bodies full of eggs. Three pairs of external gill stalks (rami)originate behind their heads and are used to move oxygenated water. The external gill rami are lined with filaments (fimbriae) to increase surface area for gas exchange.[citation needed] Four-gill slits lined with gill rakers are hidden underneath the external gills. Axolotls have barely visible vestigial teeth, which would have developed during metamorphosis. The primary method of feeding is by suction, during which their rakers interlock to close the gill slits. External gills are used for respiration, although buccal pumping (gulping air from the surface) may also be used to provide oxygen to their lungs. Axolotls displaying variations in color Axolotls have four pigmentation genes; when mutated they create different color variants. The normal wild type animal is brown/tan with gold speckles and an olive undertone. The four mutant colors are leucistic (pale pink with black eyes), albino (golden with gold eyes), axanthic (grey with black eyes) and melanoid (all black with no gold speckling or olive tone). In addition, there is wide individual variability in the size, frequency, and intensity of the gold speckling and at least one variant that develops a black and white piebald appearance on reaching maturity. Because pet breeders frequently cross the variant colors, animals that are double recessive mutants are common in the pet trade, especially white/pink animals with pink eyes that are double homozygous mutants for both the albino and leucistic trait. Axolotls also have some limited ability to alter their color to provide better camouflage by changing the relative size and thickness of their melanophores. Habitat and ecology Axolotl in captivity The axolotl is only native to Lake Xochimilco and Lake Chalco in the Valley of Mexico. Lake Chalco no longer exists, having been drained as a flood control measure, and Lake Xochimilco remains a remnant of its former self, existing mainly as canals. The water temperature in Xochimilco rarely rises above 20 °C (68 °F), though it may fall to 6 to 7 °C in the winter, and perhaps lower. The wild population has been put under heavy pressure by the growth of Mexico City. The axolotl is currently on the International Union for Conservation of Nature's annual Red List of threatened species. Non-native fish, such as African tilapia and Asian carp, have also recently been introduced to the waters. These new fish have been eating the axolotls' young, as well as its primary source of food. Axolotls are members of the tiger salamander, or Ambystoma tigrinum, species complex, along with all other Mexican species of Ambystoma. Their habitat is like that of most neotenic species—a high altitude body of water surrounded by a risky terrestrial environment. These conditions are thought to favor neoteny. However, a terrestrial population of Mexican tiger salamanders occupies and breeds in the axolotl's habitat. The axolotl is carnivorous, consuming small prey such as worms, insects, and small fish in the wild. Axolotls locate food by smell, and will "snap" at any potential meal, sucking the food into their stomachs with vacuum force. 학명 : Ambystoma mexicanum 생물학적 분류 계: 동물계(Animalia) 문 : 척삭동물문 강 : 양서류 목 : 도롱뇽목 과 : 점박이도롱뇽과 멸종위기등급 IUCN Red List 위급(CR), CITES 부속서 II 식성 벌레, 곤충, 작은 물고기 등 특징 멕시코 중부에 위치한 호히밀코 호에 서식하는 점박이도롱뇽과의 일종으로, 액솔로틀과 우파루파로 불리고 수명은 10년 정도 이다. 성적으로 성숙하기까지는 18~24개월이 걸리며, 이때 몸길이는 15~45cm이다. 먹이로는 실지렁이와 모기유충 및 작은 어류를 잡아먹는다. 다 자란 후에도 겉아가미를 지니고 있는 특징을 가지고 있다. 또한 번식이 쉽고 잃어버린 신체를 쉽게 재생하고 놀라운 장기이식 능력(다른 우파루파의 장기를 이식 받아도 거부반응이 전혀 없다)을 가지고 있다. 이로 인해 우파루파는 유전자 발현, 발생학, 신경생물학 및 재생의 규칙의 학문 및 의학적인 연구에 사용되고 있다. 분포: 멕시코 중부에 위치한 호히밀코 호, 할코 호이다. 야생개체는 멕시코 시의 상수도 수요를 충족하기 위해 이루어지는 인위적인 호수 수원 고갈로 인해 멸종위기를 맞고 있다. 현재 야생개체는 면적이 줄어들고 있는 호히밀코 호에만 서식하고 있다 📚 Reference Naver 지식백과 우파루파 https://en.wikipedia.org/wiki/Axolotl |
