Even though responsible scuba diving instructors hesitate to make trips to known seal caves, the rumor of a seal sighting quickly becomes a tourist attraction for many. Eds. [1] Monk seals prefer hunting in wide-open spaces, enabling them to use their speed more effectively. [10] Its common name comes from short hairs on its head, said to resemble a monk. [53], In early 2018 a mother and her pup were spotted around Paphos Harbour in Cyprus. This page was last edited on 28 October 2020, at 16:54. Monk seals have a slender body and are agile. [4] Data analysis indicates that only 29% of pups born between September and January survive. [citation needed], On 20 July 2019, a monk seal was spotted in Protaras bay area in Cyprus .[57]. All the other remaining subpopulations are composed of less than 50 mature individuals, many of them being only loose groups of extremely reduced size often less than five individuals.[1]. The Environment and Urbanization Minister of Turkey announced on 18 November 2019 that a plan was proposed to further preserve the species to allow the sub species of Foa, Gkova, Data and Bozburun to increase in numbers.[62]. [59] MOm is greatly involved in raising awareness in the general public, fundraising for the helping of the monk seal preservation cause, in Greece and wherever needed. They are known to forage mostly at depths of 150 to 230 feet (46 to 70m), but some have been observed by NOAA submersibles at a depth of 500 feet (150m). However, monk seals of the Cabo Blanco colony may have a gestation period lasting slightly longer than a year. Soon after, it showed signs of weakness and it was taken to a rehabilitation centre to try to save it. Hawaiian monk seals are mostly solitary and don't live in colonies like sea lions or other seals. Vaccination studies and vaccination programs. Males were probably slightly larger than females, which is similar to Mediterranean monk seals. Weighing between 375-450 pounds (170-205 kg) and 7-7.5 feet (2.1-2.3 m) in length, females are slightly larger than males. [54], In November 2018, a young monk seal was spotted at the coast of Karavostasi in Cyprus, only to be found dead at the same area a few days later. [33] Anthropogenic or human impacts include hunting (during the 1800s and 1900s) and the resulting small gene pool, continuing human disturbance, entanglement in marine debris, and fishery interactions. Cabo Blanco, in the Atlantic Ocean, is the largest surviving single population of the species, and the only remaining site that still seems to preserve a colony structure. From NOAA, several programs and networks were formed. It collected severely underweight female pups, placed them in protective care, and fed them. They are thought to be polygynous, with males being very territorial where they mate with females. [37], It is also important to consider the mothers who nurse their pups. Monk seals have two pairs of retractable abdominal teats, unlike most other pinnipeds. [44], The Recovery Plan for the Hawaiian Monk Seal identifies public outreach and education as a key action for promoting the conservation of the Hawaiian monk seal and its habitat. From NOAA, several programs and networks were formed to help the Hawaiian monk seal. Diseases of aquatic organisms, 121(2), 85-95. [17][18][19], Colonies on the Pelagie Islands (Linosa and Lampedusa) were destroyed by fishermen, which likely resulted in local extinction.[20]. On their bellies, there is a white stripe, which differs in color and shape between the two sexes. [19]:104105 Their typical lifespan is 25 to 30 years. Despite the fact Kaimana beach is popular and busy, Rocky has been routinely hauling out on this beach for several years. When monk seal pups are born, they average 14 to 18kg (30 to 40lb) and 1m (40in) in length. Toxoplasmosis in a Hawaiian monk seal (Monachus schauinslandi). [36][37] To prevent accidents and preserve monk seal, local city council acquired special educational boards and installed on city beaches. [3] The Hawaiian monk seals are adopted to be Hawaii's state mammal. NOAA is funding considerable research on seal population dynamics and health in conjunction with the Marine Mammal Center. [30], Cabo Blanco, in the Atlantic Ocean, is the largest surviving single population of the species, and the only remaining site that still seems to preserve a colony structure. [23][24], Entanglement can result in mortality, because when the seals get trapped in marine debris such as fishing nets, they cannot maneuver or reach the surface to breathe. In more recent times, they have left their former habitat and now only use sea caves for these activities. [45], On 7 April 2015, a large floating "fish" was reported near Raouche, Beirut in Lebanon, and collected by a local fisherman. [12], The Hawaiian monk seal is part of the family Phocidae, being named so for its characteristic lack of external ears and inability to rotate its hind flippers under the body. Caribbean monk seals had a relatively large, long, robust body, and could grow to nearly 8 feet (2.4m) in length and weighed 375 to 600 pounds (170 to 272kg). The males feature dark black hair while the females are dark brown or grey. Community programs such as PIRO have helped to improve community standards for the Hawaiian monk seal. The program also creates networks with the Native Hawaiians on the island to network more people in the fight for conservation of the seals. [33], Low juvenile survival rates continue to threaten the species. Their gestation period, lactation period, and sexual maturity age are unknown. Adult males are 140 to 180 kilograms (300 to 400 pounds) in weight and 2.1 metres (7 feet) in length while adult females tend to be, on average, slightly larger, at 180 to 270kg (400 to 600lb) and 2.4m (8ft) in length. [12] Monk seals as a whole vary minutely in size, with all adults measuring on average 8 feet (2.4m) and 500 pounds (230kg). [9] Although no direct links between infectious diseases and seal mortality rates have been found, unidentified infectious diseases could prove detrimental to relocation strategies. The coastal caves are, however, dangerous for newborns, and are causes of major mortality among pups when sea storms hit the caves. [26] The total population of Hawaiian monk seals is in decline the larger population that inhabits the northwest islands is declining while the smaller population on the main islands is increasing. One cause of this low survival rate is the timing of high surf around the areas of breeding, creating a threat to young pups. [43], To raise awareness of the species' plight, on June 11, 2008, a state law designated the Hawaiian monk seal as Hawaii's official State Mammal . The habitat of this pinniped has changed over the years. The breeding season takes place throughout the year, excluding the fall, but peaks during April and May. The complex politics concerning the covert opposition of the Greek government towards the protection to the monk seals in the eastern Aegean in the late 1970s is described in a book by William Johnson. [3] The nostrils are small vertical slits which close when the seal dives underwater. This is also the time when caves are prone to wash out due to high surf or storm surge, which causes high mortality rates among pups, especially at the key Cabo Blanco colony. The mother does not eat or leave the pup while nursing. [8] This low genetic variability was allegedly due to a population bottleneck caused by intense hunting in the 19th century. In an influential 1977 paper, Repenning and Ray proposed, based on certain unspecialized features, that they were the most primitive living seals. [39] Less than a month later on 25 August 2014 this female monk seal was found dead in the Mrtvi Pu bay near ian, Croatia. [27][28] In 2010, it was estimated that only 1100 individuals remained. When it is not hunting and eating, it generally basks on the sandy beaches and volcanic rock of the Northwest Hawaiian Islands. In November 2014, an adult monk seal was reportedly seen inside the port of Limassol, Cyprus. [41] Since 2001, toxoplasmosis has killed at least eleven seals. NOAA. The Hawaiian monk seal has the lowest level of genetic variability among the 18 pinniped species. Protected Resources Division." [35] In summer 2014 sightings in Pula have occurred almost daily and monk seal stayed multiple times on crowded city beaches, sleeping calm for hours just few meters away from humans. [47], On 6 January 2016, a monk seal climbed aboard a parked boat in Kuadas. The growing population there was approximately 150 as of 2004[24] and 300 as of 2016. The monk seal's physique is ideal for hunting its prey: fish, lobster, octopus and squid in deep water coral beds. [40] U.S. military forces hunted them during World War II, while occupying Laysan Island and Midway.[40]. [33] Lobsters, the seals' preferred food other than fish, have been overfished. Greece is currently investigating the possibility of declaring another monk seal breeding site as a national park, and also has integrated some sites in the NATURA 2000 protection scheme. Evidence points to monk seals migrating to Hawaii between 411 million years ago (mya) through an open water passage between North and South America called the Central American Seaway. Like other monk seals, this species had a distinctive head and face. According to the scientists involved in local projects to protect the animals, this was the first ever documented sighting of a monk seal swimming in a river. No other seals in the world have this feature. [23], The pups are born on beaches and nursed for about six weeks. The Isthmus of Panama closed the Seaway approximately 3 million years ago.[17]. The size and shape of it is unique for each one of them. [9]. [30] In 2006, twelve pups were born in the main islands, rising to thirteen in 2007, and eighteen in 2008. On 8 March 2011, the BBC Earth news[30] reported that a pup seal had been spotted on 7 February while monitoring a seal colony on an island in the southwestern Aegean Sea. It is illegal to kill, capture or harass a Hawaiian monk seal. Hawaiian monk seals mainly prey on reef dwelling bony fish, but they also prey on cephalopods, and crustaceans. They are the only earless seals found in tropical climates. Fish stock decline in the Caribbean starved the remaining populations. [37] Some of the infectious diseases that pose a threat to the Hawaiian monk seal populations include distemper viruses, West Nile Virus, Leptospira spp., and Toxoplasma gondii. Further investigations revealed that she was pregnant with a pup. Its grey coat, white belly, and slender physique distinguish them from their cousin, the harbor seal (Phoca vitulina). [47] Identification and mitigation of these and other possible factors limiting population growth represent ongoing challenges and are the primary objectives of the Hawaiian monk seal conservation and recovery effort. [14] The nostrils are small, vertical slits, which close when the seal dives under water. All three monk seal species were classified in genus Monachus until 2014, when comparison of the species' mitochondrial cytochrome b DNA sequences led biologists to place the Caribbean and Hawaiian species in a new genus, Neomonachus. This was the first sighting of the species in the region since Lebanese authorities claimed to have found a population of 1020 other seals on their coasts 70 years earlier.
