115) Halechiniscus grevini
Halechiniscus grevini is in the Phylum Tardigrada which are water bears. They are micro-animals that can be found in the East North Atlantic Ocean and the Mediterranean Sea (Van Der Land). This creature has the ability of regenerating its sensillum, which is a filament sensory organ.
Soon after the sensillum has been amputated the hard outer honeycomb layer of the organism folds in on itself to create the joint from which the sensillum can grow from (Kristensen). Once that has been done the tormogen cells found in the basal layer of the honeycomb layer begin to proliferate and create a pocket (Kristensen). From this pocket protrudes a long structure that will make the outer layer of the sensilllum. Glial cells will also work with the tormogen cells to create a stronger, harder structure as the sensillum continues to grow and differentiate (Kristensen). Next the trichogen cells begin to proliferate and differentiate into the internal structure of the sensillum. Finally sensory cells will begin to differentiate from the cilia-supporting cells and produce the dendrites in the sensillum (Kristensen).
