From CIMA (Centro de Investigaciones Medioambientales del Atlántico, S.L.) (Atlantic Environmental Research Center), we want to show you what we do in and out our offices.

On this page you can find a series of small videos called «Things we do in CIMA», which will help us to explain what we do and how we do it. All this to approach the world of marine biology and oceanography.

– «Things we do in CIMA» #1: Benthic sample triad: We separate organisms from our last benthic sample (obtained from seabed) with a «triado» (separation into three different groups). In this case, we are going to separate Molluscs: animals with shell, such as snail (note that cephalopods are also molluscs, moat of them have an internal shell called «Cuttlebone»); we will also separate Annelids or Polychaetes: segmented body worms (this is a huge phylum in which more than 16.700 species have been described, including polychaete marine worms, earthworms and leeches); finally, we will separate Crustaceans: animals with exoskeleton, such as crabs (crustaceans are a large subphylum of arthropods with more than 67.000 species, including several groups of animals such as lobsters, crabs, prawns and barnacles).

What is the use of doing all this?

Knowing the quantity of mollusks, polychaetes and crustaceans gives us a rough idea of the environmental quality of the area where we have collected the sample.
