The “Proyecto ESPER” is a research program established between the Royal Belgian Institute of Natural Sciences and the Universidad Peruana Cayetano Heredia with the support of the Directorate General for Development Cooperation (DGDC) - Belgian Development Cooperation

Here we are finally. Our underwater exploration has just started.
Our delay is due to the hard time we had to get hold of the diving equipment shipped from Brussels by air cargo. The Peruvian customs are not easy to handle. We spent 7 hours at the airport on Monday 17th, filling forms, dealing with officials, unpacking/repacking our 239 kg of equipment. Finally after a stop at the bank… everything was ready to take out… the next day, since it was too late to re-enter the warehouse.

We still had to complete our equipment before taking the road. We first rent a pick-up (that made the largest hole in our budget). Then, on Tuesday night we collected Eduardo at the airport.
On Wednesday Philippe progressed through his driving training through Lima (a real corrida) to reach the unique diving shop in Peru and purchase diving weights. We also had to build up an oxygen diving rescue kit (No DAN equipment available here). Without the help of Yuri, shopping in Lima would never have been possible.

Finally on Thursday we had completed our first tank fillings and were ready for our first immersions. Pucusana, one hour south of Lima was our target as training before the real things would start north.
As the ESPER Proyecto is not just a collecting trip, but also an educational project, in the frame of the Belgian cooperation to the development of Peru, several students will have the opportunity to participate to the field work.
Rodrigo Castro from UPCH (Universidad Peruana Cayetano Heredia) was the first one.

We left Lima in the afternoon of Friday 21 with more than 500 kg of equipment.

Unloading the equipment after a dive in Bahia Tortuga



Thursday September 27
We are on our way since almost a week by now and have reached Trujillo after several stop-overs.
Chancay was our first base, from where we had to dive in Ancon. Unfortunately the weather was too windy, the Ocean too rough to dive and we decided to head further north.
Casma “Ciudad del Eterno sol” was reached Saturday 22 at night. Katherine Altamirano from UNMSM (Universidad Nacional Mayor de San Marcos) , the second student joined us for four days. Considering the amount of equipment, the places where we stay need to have rooms at ground level and if possible an area where to rinse the diving gear, install the noisy compressor at night in order to charm our guests for at least 2 hours… The Hotel ”El Farol” was the ideal place where to stay to reach different sites during the following days.

Sunday 23: North of Casma. Two shallow dives in Bahia Tortuga. Easy departure from the beach.

Monday 24: Bahia Samanco. Two dives in Punta Ansumo and Caleta Colorado.
It wasn’t easy to reach the sea, the road through the dunes had been covered by a thick layer of sand. Right time to appreciate the four wheel drive!



Tuesday 25: Chimbote. Two dives in Islote Ferrol and Isla Blanca. The harbor is a busy place with hundreds of fishing boats. Luckilly Yuri has worked with IMARPE (Instituto del Mar del Peru) in the past where we were welcome to get dressed and leave the truck safely.

Yuri would like to find a sponge as big as that... may be soon!


No, Katherine hasn't been sick!
The boat was just covered all over with guano...

Every time we need to dive, we have to find the help from fishermen willing to rent us their boat.

So far our dives were conducted smoothly, although a strong swell makes it rather difficult to take photographs and collect specimens. Quite often we roll upside down, or we are pushed several meters away from our target.

Thursday 26: After packing and loading the truck we reached Trujillo at night, where we are presently hosted by Yuri’s parents. This will be our base for the next two days of underwater exploration.

The main observation after a few immersions is that in this region the sponge biodiversity is rather low. Two or three Calcarea species and less than 10 species of demosponges. Hopefully we will find a larger number of species once we reach the Islas Lobos de Afuera in a few days. From there we will be unable to reach Internet and you will have to wait for the next episodes of our adventure.

The expedition will start on September 17.
Our first dives are planned off San Lorenzo Island near Lima.


Very little is known about the Porifera fauna of Peru despite the ecological importance of that group and its potential source of economical revenue, since it is one of the richest marine natural sources of new chemical structures. As part of a National Action Plan for Marine Biodiversity Assessment, the Universidad Peruana Cayetano Heredia (UPCH) has launched a program to inventory the diversity of taxonomic groups along the entire coast of Peru. Since 2004 the RBINSc is coordinating such an inventory in Southern Chile in cooperation with the Museu Nacional of the Federal University of Rio de Janeiro (MNRJ) and the Muséum d’histoire naturelle de Genève (MHNG). Enriched with three years of collaboration including 5 expeditions, our group will extend its geographical area of investigation to Peru, in cooperation with local scientists and institutions. Within the first year of our project, we plan to inventory the sponge fauna in 10 localities already under study for other taxa, roughly from Lima to the Ecuadorian border. This study will allow local scientists to develop a reference collection of Porifera, becoming acquainted with basic protocols for the identification of species within this Phylum, and will possibly also allow the determination of northern distribution limits for several species known from the central Chilean coast.
