[18] The fur coats of males is generally black, and brown or dark gray in females. There is no vaccine for this disease and it is extremely difficult to treat. Their gestation period, lactation period, and sexual maturity age are unknown. Monk seals have a slender body and are agile. Introduction to Seals. Now that they have gone extinct, we are left to wonder what the Caribbean would be like if these majestic animals were still alive today unnafected by humans. Currently, around 1,700 monk seals remain. [26][27], 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. Infected cats rarely show any signs of infection. Many of the monk seals slipping back into the main Hawaiian Islands in the early ’70s landed first on the shores of Niihau, the island closest to the Leewards. In fact, Pōhaku might not be alive today if someone hadn’t promptly reported her logging. Shortly after NOAA rescued Pōhaku, a young male monk seal (RKC1) was found dead on the windward side of Oʻahu. NOAA team conducting an ultrasound exam to assess RO28/Pōhaku condition. Currently, its entire population is estimated to be less than 600 individuals scattered throughout a wide distribution range, which qualifies this species as endangered. And even if successful, the life-saving efforts she has undergone in treatment are intensive, laborious, risky to the animal and the caregivers. While opinions on the precise causes of this epidemic remain divided, the most likely cause is a morbilivirus or a toxic algae bloom. on May 07, 2020, Stay informed of all the latest regional news around NOAA Fisheries, The Toll of Toxoplasmosis: Protozoal Disease Has Now Claimed the Lives of 12 Monk Seals and Left Another Fighting to Survive, New Study Reveals Most Impactful Threats to Main Hawaiian Islands Monk Seals, 20 Memorable Marine Stories, Videos, and Photos of 2020. Pups are about 3.3 feet (1 m) long and weigh around 33–40 pounds (15–18 kg), their skin being covered by 0.4-to-0.6-inch (1.0 to 1.5 cm) fur, usually dark brown or black. Adults were darker than the paler and more yellowish younger seals. This could include capturing individuals on multiple occasions to monitor for disease exposure or actual illness.The seals would have to bear the cost of this enhanced monitoring, but it may be the only way we can save lives until the source of this issue is more holistically addressed. Juveniles and subadults prey more on smaller octopus species, such as Octopus leteus and O. hawaiiensis (nocturnal octopus species), and eels than do adult Hawaiian monk seals. The species may have evolved in the Pacific or Atlantic, but in either case, came to Hawaii long before the first Polynesians. [22]:104–105 Their typical lifespan is 25 to 30 years. Four Hawaiian monk seals were successfully released Aug. 5 on Midway Atoll National Wildlife Refuge after spending more than 10 months in Kailua-Kona’s marine mammal hospital. Credit: Jeffreyw (CC BY 2.0). Adult seals feed mostly on larger octopus species such as O. cyanea. Shark attacks cause a high pup mortality, from 19% to 39%. The Greek Alonissos Marine Park, that extends around the Northern Sporades islands, is the main action ground of the Greek MOm organisation. Its current very sparse population is one more serious threat to the species, as it only has two key sites that can be deemed viable. 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. [3] The two genera of monk seals, Monachus and Neomonachus, comprise three species: the Mediterranean monk seal (Monachus monachus), the Hawaiian monk seal (Neomonachus schauinslandi), and the Caribbean monk seal (N. tropicalis), which became extinct in the 20th century. As of 2020, it's thought that there are roughly 500 pairs of monk seals remaining in the world. Fish stock decline in the Caribbean starved the remaining populations. They likely bore a single pup every two years. Once back in the wild, he spent a few weeks exploring the Kalaupapa peninsula with other weaned pups, before making the journey to Oʻahu. They are known to forage mostly at depths of 150 to 230 feet (46 to 70 m), but some have been observed by NOAA submersibles at a depth of 500 feet (150 m). They prefer hunting in wide-open spaces, enabling them to use their speed more effectively. The Isthmus of Panama closed the seaway 3 Mya. Indoor cats not only live much longer, healthier lives than outdoor cats, but they are also far less likely to contract the parasite. In ancient Greece, the Mediterranean monk seals were placed under the protection of Poseidon and Apollo because they showed a great love for the sea and the Sun. It will outline a suite of actions that we believe will reduce the impact of toxo on monk seals and other native wildlife in Hawaiʻi. [32] These two key sites are virtually in the extreme opposites of the species' distribution range, which makes natural population interchange between them impossible. Given the small size of the monk seal population, every individual is important. They feed mainly on bony fish and cephalopods, but they are opportunistic. Additionally, their slender, torpedo-shaped body and hind flippers allow them to be very agile swimmers. [38] As early as 1688, sugar plantation owners sent out hunting parties to kill hundreds of seals every night for blubber oil to lubricate machinery. Monk seals are polygynous, and group together in harems. Males were probably slightly larger than females, which is similar to Mediterranean monk seals. †Neomonachus tropicalis. 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.
