New Recorded of Saltwater Crocodile Crocodylus porosus Schneider, 1801 from East Coast Mangrove Ecosystem in Surabaya, East Jawa, Indonesia

A single specimen of saltwater crocodile Crocodylus porosus Schneider, 1801 (1.50 cm in length) was captured and photographed by a local fisherman by gill net at fishpond around mangrove ecosystem of east coast Surabaya on December 2020. The location where the estuarine crocodile caught is an important wetland area in Surabaya with an excellent mangrove cover. Wonorejo mangrove location is about 10 km from the centre of Surabaya, the second-largest city in Indonesia. This finding is considered as a first reported of C. porosus in Surabaya, and at the same time is proof of the importance of the mangrove area on the east coast of Surabaya as a habitat for wildlife that must be conserved appropriately. Routine monitoring of mangrove areas, including their wildlife, is essential so that they are not displaced by the development of the city which changes the land function to become a residential area.

Names of Large Exotic Animals and the Urheimat of Japonic

This article argues that three words designating large tropical animals not endemic for Japan: kisa ‘elephant’, tora ‘tiger’, and wani ‘saltwater crocodile’ were borrowed into Japonic from Austroasiatic or Kradai languages. If so, this becomes another important piece of evidence for locating the Urheimat of the Japonic Language family in Southern China and/or Northern South-East Asia driving yet another nail into the coffin of the ‘Altaic’ theory. Since all these words are disyllabic, they also contribute to the reconstruction of the disyllabic words in Austroasiatic and Kradai. This is especially important in the case of Kradai, where in spite of the rather recent fall of the monosyllabic curtain, the idea about the ‘primordial’ nature of the monosyllabic structure is still enjoying considerable support.

Feeding Regime and Management of Captive Saltwater Crocodile, Crocodylus Porosus in Kota Tinggi, Johor

Crocodylus porosus is the largest species of crocodile and can be found in estuarine and riverine area in Malaysia. Crocodile in captivity can be found in Malaysia for various purposes such as tourism, conservation and leather industry. However, the management practice in established crocodile farm varies across park for example in terms of feeding regime. Thus, this study focusses on the feeding regime of C. porosus in captivity and evaluation of management of crocodile of Teluk Sengat Crocodile Farm. This study was carried out for 35 days in two different ponds of Teluk Sengat Crocodile Farm, Kota Tinggi, Johor. The results show majority of the food given to crocodile were chicken (64%), followed by fish (28%) and prawn (8%). Prawn was only given to juvenile crocodile every day, while fish and whole chicken were given to adult crocodile once a week. The feeding frequency are adequate for the juvenile crocodile however, the feeding quantity for adult pond are worrying. Future research should be conducted on other captive population of C. porosus in other areas in Malaysia as well to better understand the overall management practices in Malaysia.

Integrating local perspectives into conservation could facilitate human–crocodile coexistence in the Ayeyarwady Delta, Myanmar

Conservation will always fail when it does not address the drivers of biodiversity loss, which in many cases involves understanding human behaviours and the attitudes that underlie them. The saltwater crocodile Crocodylus porosus is a keystone species in mangrove wetlands but also a dangerous predator that affects people's safety and livelihoods. Although saltwater crocodiles are protected under the Myanmar Biodiversity and Protected Area Law, the government has not integrated local people's attitudes into conservation and management. As a consequence, saltwater crocodiles, although categorized as Least Concern on the IUCN Red List, are restricted to a single protected area, Meinmahlakyun Wildlife Sanctuary, in Myanmar. To examine local attitudes towards the species, we investigated local knowledge about the environment, crocodiles, habitats and threats, awareness of human–crocodile conflict, and perceptions of the benefits and impacts of saltwater crocodile conservation through questionnaires in 244 households in 17 villages. We found that people were highly knowledgeable about the local environment, saltwater crocodiles, and their habitats. People with seasonal livelihoods that rely on natural resources from Meinmahlakyun had negative attitudes towards crocodile conservation. People were likely to have negative attitudes if they perceived there were no benefits from conserving the species. Law enforcement through restricting resource access does not enhance conservation success and builds resentment towards the conservation of the species. Local people suggested that, as a basis for management, understanding risks posed by crocodiles was the best approach to facilitate human–crocodile coexistence in the Ayeyarwady delta region.
