| Twelve laboratory experiments to evaluate the egestion in short time periods at the herbivorous copepod Eucalanus subtenuis, were carried out with the aim to obtain data about the morphometry, volume, faeces production rate and coprophagy index, as well as to detect some feeding strategy. Two feeding treatments with different phytoplankton size classes (measured as chlorophyll a concentration) were applied to the copepod: 0 -25 µm (pico and nanophytoplankton) and 25-85 µm (microphytoplankton). The food source was obtained from the surface water in the Caribbean central coast region, between February and May 2001. At copepods with mean total size of 1855.45 +/- 20.50 µm, faeces length fluctuated between 66.66 and 315 µm, being longer when copepods fed with... |

| A collection of porcellanid crabs was made on che Isla Gorgona, Colombia, during a one week period, sampling as completely as possible a number of different biotopes. The majority of the 16 species in six genera that were collected occurred in the formations of pocilloporid corals and between stones in the sublittoral zone. Clastotoechus gorgonensis sp. nov. lives in the burrows of the sea urchin Echinometra vanbrunti A. Agassiz in the intertidal zone. Seven species are new additions to the porcellanid fauna of Gorgona and two of them are new records for Colombia. A total of 18 species are now known to occur on Isla Gorgona. |
