Scientific identify: Boulengerula taitanus
Scientific classification:
Phylum: Chordata
Class: Amphibia
Order: Gymnophiona
Family: Caeciliidae

What does it appear like? This is a protracted and skinny animal, and superficially it resembles an earthworm. Adults are 20-33 cm in size, and alongside the size of the metal blue physique are small encircling grooves, which give the animal a segmented look. The head and tail are bullet formed. The eyes of this amphibian are a lot diminished and are hid beneath bone and pores and skin. A pair of small sensory tentacles will be projected from the top. 

Where does it dwell? This species is simply identified from the Taita hills and their fast neighborhood in southeastern Kenya. It is a fossorial animal, and spends nearly all of its time underground. The caecilians are widespread in soils of forests and agricultural landscapes.


Caecilians make wonderful dad and mom. They make investments a substantial amount of time and vitality of their younger to guarantee they've the most effective begin in life. Nowhere is that this extra obvious than within the Taita hills caecilian of Kenya. It has been identified for a very long time that the feminine would lay her eggs in a subterranean lair and jealously guard them till they hatched by coiling her sinuous physique round them. It was additionally identified that the fetuses of this species had well-developed tooth.

The presence of these tooth in such younger animals puzzled scientists, and the total signifi cance of them has solely not too long ago been found. It seems the entire nurturing conduct of this animal is much more sophisticated and attention-grabbing than initially assumed.

The younger caecilians stick with their mom for round two months after they hatch. Only mammals often present this degree of maternal care, and it was unclear precisely what the younger had been doing for such a protracted time period. Caecilians should not have mammary glands and teats like mammals; subsequently, extending intervals of breast feeding are out of the query.

The slender, pink younger most likely survive on yolk shops for his or her fi rst few days of life, however scientists videotaping captive litters observed some odd conduct. The younger could possibly be seen nuzzling and butting their mom’s physique, and it was ultimately discovered that they had been peeling offthe outermost layers of her pores and skin and consuming it.

When females of this species are brooding, their pores and skin turns into pale and thickens significantly till it's twice as deep as that of a nonbrooding feminine. The pores and skin cells change from the traditional fl at, lifeless selection to succulent parcels fi lled with proteins and fat. To allow the younger to peel away this nutritious pores and skin they're born with quite a lot of small, hooklike tooth. On this nutritious weight-reduction plan of maternal pores and skin, the offspring thrive, and each week their physique size will increase by 11 %. After two months of feeding on this manner, the younger have grown sufficiently to allow them to go away their mom and go their very own manner.

Key Facts

  • Around 170 species of caecilians have to date been identifi ed, however due to their very secretive methods and barely visited habitats, it is vitally seemingly that many extra species are nonetheless to be found. They vary in measurement from 10 to 150 cm. They are all discovered within the tropics.
  • The caecilians first seem within the fossil document greater than 150 million years in the past. They have turn out to be so nicely tailored to a subterranean existence that they've misplaced lots of the typical outward traits of the amphibians.
  • Of all of the land-living vertebrates, solely the birds haven't any actually subterranean representatives. The amphibians have the caecilians, the reptiles have the worm-lizards and snakes, and the mammals have the moles and a large number of different burrowing kinds. An underground life guarantees ample food and relative security from floor predators, however it requires main adjustments to the animal’s physique. In amphibians and reptiles, these adjustments have led to animals that look strikingly related.
  • One of the distinctive options of the caecilians is the pair of small tentacles discovered between the eyes and nostrils. These will be projected and withdrawn and rely upon many muscle tissues and different options sometimes related to the vertebrate eye. Their precise perform is unknown, however it's thought they collect small samples of air for the style organs within the roof of the mouth. In snakes that is achieved by the fl icking tongue.
  • Most caecilians are terrestrial burrowers, excavating tunnels through the use of their inflexible, compact head as a battering ram. Some species will enterprise to the floor through the evening or if their tunnels are flooded by heavy rains.
  • Some of the caecilians within the household Typhlonectidae are aquatic in addition to being the biggest of these limbless amphibians. The Typhlonectidae are solely present in South America and lack the little tentacle that each one different caecilians have. The aquatic species have a fleshy fin extending alongside the rear part of their physique enabling them to swim by the water in the identical manner as an eel.
  • All caecilians are carnivorous. They have an under-slung jaw, enabling them to subdue and eat suitably sized prey encountered of their tunnels. Worms will typically be taken, as will different soft-bodied invertebrates of the soil and leaf litter.
  • Other than pores and skin feeding, the caecilians present a spread of reproductive oddities. Many species give delivery to dwell younger, and the fetuses of some species are nourished inside the feminine on uterine milk and the thick lining of the uterus. The fetuses have elaborate gills. In the terrestrial species, these are very lengthy and branching, extending from simply behind the top of the child amphibian. In the aquatic species, these gills appear like small, leaf-shaped sacs. In the adults of all however one species, the job of gasoline alternate is taken over by lungs.
