The majority of the cocoons hatched only one hatchling. Pheretima, Perionyx excavatus, Glossoscolecidae, Acanthodrilidae, and Eudrilidae are also species of earthworms that you may not know of just by looking at their name. dKoL!8Ka#EV,@V!\j8ZFbp6EE<9cn=N6j0nf;(&;QU6bUD')c@\ The incubation period of cocoons of P.excavatus was ±19 days. In laymans' terms, that means that the "collar" of the mature P. excavatus is much closer to its head than the E. fetida's. There are 3 main types of earthworms; the compost worm, the earth-worker worm, and the root-dwelling worm. Cocoons were produced at a mean rate of 1,1 cocoons per worm per day. In the present study the Eudrilus eugeniae were grown in cow dung and their life cycle were studied in different days of intervals like 15, 30,45 and 60 days.

Perionyx excavatus is an earthworm with an iridescent blue or violet sheen on its skin which can be seen clearly under bright light. Thus, it is crucial to establish P. excavatus as a model system to investigate mechanisms of CNS regeneration. Once the perionyx excavatus reach a length of about 7.5cm. It is also found in parts of South America, Puerto Rico, and some areas of the United States (south of the Mason Dixon line and Gulf Coast region). In die reël het slegs een wurm per kokon uitgebroei. Ultra structure observed under Scanning Electron Microscope (SEM) revealed that wall of the cocoon is porous (which helps in aeration) and the terminal part of the cocoon is softer than that of middle part which … The effect of ECF on cell cycle analysis and mechanism of cell death have also been investigated.

The blue worms display four distinct type of colours at different stages of sexual maturity. Each of the four earthworm species differed considerably in terms of responses to and tolerance of different temperatures. The life cycle and the potential of Perionyx excavatus for breaking down organic wastes and turning it into rich soil amendment has been documented by various authors under controlled conditions (Kale et al 1988; Reinecke and Hallatt 1989, Hallatt et al 1990; Reinecke et al 1992; Hallat et al 1992). However, there is scanty information on the abundance and diversity of the gut bacterial flora in different earthworm genera fed with a similar diet, particularly Eisenia foetida and Perionyx excavatus.
