suffered depletion in oxygen and died, whereas animals decompressed using slow<br />
decompression rates survived. These findings made evident the critical effect <strong>of</strong> rapid<br />
decompression on mammals. Conversely Treude et al. (2002) studied the metabolism<br />
and decompression tolerance <strong>of</strong> several species <strong>of</strong> scavenging lyssianoid amphipods<br />
in the deep Arabian Sea. During the experiment the amphipod were decompressed<br />
from their ambient at 3950-4420 m depth to atmospheric pressure during recovery.<br />
Specimens <strong>of</strong> the genus Paralicella did not survived decompression <strong>of</strong> more than 300<br />
bar, and because <strong>of</strong> its limited decompression tolerance this genus might be classified<br />
as stenobathic. On the other hand Abyssorchomene distincta and Eurythenes gryllus<br />
had a high tolerance to pressure changes. Both species were recovered without<br />
apparent decompression problems and were classified as eurybathic. These results are<br />
very important since it is evident that some invertebrate species are able to tolerate<br />
decompression without detectable lethal effects; which could be the case <strong>of</strong><br />
echinoderm embryos and larvae.<br />
