Crossing marine lines at TernateThe volcanic island of Ternate is located in the northern Moluccas. Little is known about the marine life of this area. During this expedition the marine diversity of Ternate will be the focus of exploration. The research team is particularly interested in certain species groups. Their presence or absence can tell us more about the geograpical boundaries of marine species in this area.
The expedition, lead by Dr Bert W. Hoeksema, will be on Ternate between 22 October and 17 November. Stay updated through this weblog!

In 1896,Kieschnick described a total of 50 sponges of which22 new to science, however his tutor wasn’t satisfi... lees verderStel een vraag / bekijk eerder gestelde vragen Highlight of the day - Nicole de Voogd & Sancia van der Meij - 6 november 2009This nudibranch (Ceratosoma sinuatum) and bivalve (genus Tridacna) do their best to look very much alike, even the color patterns of both animals can vary greatly.... lees verderStel een vraag / bekijk eerder gestelde vragen Entering the water - Charles Fransen - 4 november 2009The Naturalis 'Zeeteam' enters the water, watch the footage on YouTube (partly in Dutch):http://www.youtube.com/watch?v=cd_BQlpThxw... lees verderStel een vraag / bekijk eerder gestelde vragen Highlight of the day - Arjan Gittenberger - 1 november 2009In addition to the shrimps described by Charles Fransen, we have found a variety of other strange parasites and/or symbionts that live inside ascidians and salps.

Hide or become invisible. One way would be to spent your live inside sponges, bivalves or ascidians or you could ornament and color yourself in such a way you are not noticed by the killer fish.
