TABLE 2. Abundances and densities (individuals/10 cm 2) of Tardigrada in the different sea regions sampled during expeditions ANDEEP 1, 2, 3 and ANDEEP-SYSTCO. A total of 1,210 of the 1,397 individuals from a total of n=130 core samples were identified to genus and mostly to species level (see Tables 3–4).
