Note on an old female monk seal that died in Croatia in 2014

by Prof. Dr Đuro Huber, Biology Department, Veterinary Faculty, Zagreb, Croatia

The individual concerned was photographed for the first time on 08 March 2009 by the Monk Seal Group (Jasna Antolović, chair) in the Nature Park Kamenjak at the tip of the Istria peninsula. Confirmed sightings of the monk seal in the area started already in 2004. However, at that time the animal did not have the distinguishable scars on the base of the neck and the base of the hind left flipper. It can be stated that this animal stayed in the area at least for five years and probably almost for 11 years. Automatic cameras pictured her on many occasions in the meantime, but she was also seen several times around the island of Cres, as well.

Since the winter of 2013/14 she was frequently found resting on public beaches not exhibiting fear of people. On 21 February 2014 Đuro Huber observed and photographed her in a perfect physical condition sleeping on a beach and breathing 6 times per minute. Some foamy yellow liquid was seen coming out of her nose on several occasions. Jasna Antolović once provided a bacteriological test of the liquid and Pseudomonas aeruginosa bacteria were determined. The seal continued to use beaches near urban areas through summer 2014 when the same beaches were crowded with people. Even close proximity approaches by humans on the shore and in the water were tolerated.

A new sighting of the Mediterranean monk seal in the Marmara Sea

Non-open access journalsÖzgür Emek Inanmaza, Özgür Değirmenci and Ali Cemal Gücü. 2014. A new sighting of the Mediterranean Monk Seal, Monachus monachus (Hermann, 1779), in the Marmara Sea (Turkey). Zoology in the Middle East, 60 (3): 278-280. DOI:10.1080/09397140.2014.944438

[…] In total six caves displaying Monk Seal resting/breeding characteristics (see Karamanlidis, Pires, Silva, & Neves, 2004; Gucu, Gucu, & Orek, 2004) were discovered. There was clear evidence in one of those cases, namely the peculiar odour and tracks on the inner sandy beach, and this indicated the recent presence of a seal in the cave. The cave had a surface opening with an inner area and a platform formed by sand, pebbles and large boulders. During the surveys, seals were sighted at four different occasions on 21 April, 27-30 May and 14 June 2014, and were recorded on a video. […]

New report on monk seals of Gyaros, Greece

1st Annual Conservation Status Report of the Mediterranean Monk Seal Population at the island of Gyaros

Recent Publications

[…] Annual pup productivity

The minimum mean annual number of births (n = 7.75) recorded at the island of Gyaros is one of the highest recorded for the species in the Mediterranean Sea and could be higher if systematic assessments of natality were conducted throughout the breeding season at each site in the years 2004 – 2011. Systematic surveys of annual pup production at Cabo Blanco in the Western Sahara (González et al., 2002), the Northern Sporades, Kimolos & Polyaigos, and at Karpathos & Saria (MOm, 2007) yielded counts of 25.0, 8.4, 7.9, and 3.7, respectively.

Tourism could help save Mediterranean monk seals, but if unmanaged it will only accelerate their demise

Giuseppe Notarbartolo di Sciara


[…] Unfortunately, the monk seal breeding season happens to coincide in part with the peak of the tourist season, a coincidence likely to result in making the seals even more endangered than they already are, as I had the opportunity of documenting yesterday in an undisclosed location of the Northern Dodecanese, in Greece.

There, sheltered on a small sandy beach at the far end of a large cave carved in the cliff of a small, uninhabited islet, lives today a female monk seal with her small pup. As it happens, the location is also very popular with tourists from nearby islands, who converge there aboard day-trip boats organised by local operators, as well as with their own vessels; and the word has spread that seals can be visited in the cave.

Well-managed, tourism could be a bonus for monk seal conservation because of the high value that visitors attribute to such charismatic animals. This value can be harnessed to the benefit of the local communities, which would then strive to protect the seals or, at a minimum, stop destroying them. However, in the current total absence of management, anyone can imagine the amount of disturbance that this seal pair is subjected to, in a most critical phase of their existence and in a moment in which their quiet and peace should be guaranteed at all costs.

New publication confirms coastal diet for Mediterranean monk seal

Recent Publications

Non-open access journalsAlexandros A. Karamanlidis, P. Jeff Curtis, Amy C. Hirons, Marianna Psaradellis, Panagiotis Dendrinos and John B. Hopkins III. 2014. Stable isotopes confirm a coastal diet for critically endangered Mediterranean monk seals. Isotopes in Environmental and Health Studies, http://dx.doi.org/10.1080/10256016.2014.931845.


Understanding the ecology and behaviour of endangered species is essential for developing effective management and conservation strategies. We used stable isotope analysis to investigate the foraging behaviour of critically endangered Mediterranean monk seals (Monachus monachus) in Greece. We measured carbon and nitrogen isotope ratios (expressed as δ13C and δ15N values, respectively) derived from the hair of deceased adult and juvenile seals and the muscle of their known prey to quantify their diets. We tested the hypothesis that monk seals primarily foraged for prey that occupy coastal habitats in Greece. We compared isotope values from seal hair to their coastal and pelagic prey (after correcting all prey for isotopic discrimination) and used these isotopic data and a stable isotope mixing model to estimate the proportion of coastal and pelagic resources consumed by seals. As predicted, we found that seals had similar δ13C values as many coastal prey species and higher δ13C values than pelagic species; these results, in conjunction with mean dietary estimates (coastal=61 % vs. pelagic=39 %), suggest that seals have a diverse diet comprising prey from multiple trophic levels that primarily occupy the coast. Marine resource managers should consider using the results from this study to inform the future management of coastal habitats in Greece to protect Mediterranean monk seals.

First monk seal images from the maternity cave of the Desertas Islands

by Rosa Pires, Parque Natural da Madeira Service

For the second year in a row, Mediterranean monk seal images have been collected from the automatic cameras installed in the maternity cave of the Desertas Islands. Together, these are the first images ever taken of monk seals inside a cave in Madeira.

The cameras were installed when there was no seal activity in the cave, in order to avoid any possible disturbance.

Although the 13,000 images have yet to be properly analysed, a first look confirms once again that this system is actually an excellent tool to monitor the population. The pictures are now of a better quality (light and framing), improved by the experience gained during the first implementation of the system in 2012.

The results obtained during 2012 allowed us to observe events and situations which would otherwise have been missed, including two dead pups and two others alive. The total of 5 births counted in 2012 was the highest number ever recorded in the Desertas Islands — and is another indication that the monitoring of the population has improved significantly using this technique.

The peak activity of monk seals inside of the cave was recorded in October, coinciding with the occurrence of the largest number of births.

The continuation of this work and its expansion into other areas used, or with the potential to be used, by monk seals is undoubtedly an excellent investment in the monitoring of this species and consequently for its conservation.

Open access journalsErdem Danyer, Işıl Aytemiz, Ali Cemal Gücü, Arda M. Tonay. 2014. Preliminary study on a stranding case of Mediterranean monk seal Monachus monachus (Hermann, 1779) on the Eastern Mediterranean coast of Turkey. Journal of the Black Sea / Mediterranean Environment 20(2): 152-157. [Download]


The Mediterranean monk seal Monachus monachus (Hermann, 1779) is one of the critically endangered species in the world and in the northeast Mediterranean Sea there is a continuously breeding population. On 28 February 2014, 3-3.5 months old, male Mediterranean monk seal stranded near Yasilovacık Harbour, Mersin. Gross necropsy was carried out one day later. The seal was emaciated and lungs were pneumonic. This paper summarizes the preliminary findings of the gross necropsy.
