TARDIGRADE, AN
EXTREMOPHILE MICROANIMAL

Tardigrades, kriawn colloquially as water bears or moss pigtets, are a phylum |
of eight-legged segmented micro-animals. Their life is not really known,
‘however, tardigrades are able to stop their metabolism dnd become Immortal |
| (state cruptobiosis). These qualities make it an amazing super champion
à resistance animal

17. ture Applications

Diminish effectiveness of immune system makes microbes
potentially harmful and resistant for onboard crew. Pesudomonas
aeruginosa & Staphylococcus aureus are opportunistic pathog
in skin flora. With the advent of antibiotics resistant strains
these species in particular can be life threatening
