Malayan Porcupine Hystrix brachyura at Jemaluang, Johor, Peninsular Malaysia

Location: Jemaluang, Johor, Peninsular Malaysia.

Habitat: Metalled road, next to lowland swamp forest and primary forest.

Date and time: 29 August 2003, 21:45 hrs.

Description of record: An adult (head and body length 60 cm) was found on a metalled road, a victim of traffic road kill (Fig. 1.). The subject appeared to have been crushed in the abdominal region, as indicated by the naked patch extending from its back to its abdomen, and with its innards extruding from the posterior end. The larger quills had become detached from its body.

Remarks: The colour of this specimen appears brownish, in contrast to ‘typical’ examples in which the anterior part of the body is black and sharply in contrast with the white posterior. A typical example from Sungai Bantang, Johor, is shown in the inset to Fig. 1. Similar brownish specimens also appear to exist in Singapore’s central forests, 80 km to the south of Jemaluang (N. Baker, pers. comm.).

Shepherd & Shepherd (2012) summarize the range of this species as “Brunei, Cambodia, Indonesia [Kalimantan, Sumatra], Laos, Malaysia [Peninsular Malaysia, Sabah, Sarawak], Myanmar, Singapore, Thailand and Vietnam. Also found in Bangladesh, China, India and Nepal”. The state of Johor, Peninsular Malaysia thus lies in the southern part of its range.

Recent amphibians and reptiles observed at
Panti Forest Reserve, Johor, Peninsular Malaysia

Location: Bunker Trail, Gunung Panti Forest Reserve, Kota Tinggi District, Johor, Peninsular Malaysia

Habitat: Lowland secondary dipterocarp forest and freshwater swamp-forest with shallow streams.

Date and time: 27 June 2016, 07:30-12:00hrs & 17:30-21:00 hrs.

Identity of subjects and descriptions of records: Malayan Krait, Bungarus candidus (Reptilia: Squamata: Elapidae), one roadkill adult found near the entrance of Bunker Trail in the early morning, Fig. 13.

Remarks: The records presented here summarize a recent rapid herpetofaunal survey (8 hours) of Panti Forest. Among the fourteen recorded species two reptiles, Aphaniotis fusca and Bungarus candidus, were not recorded during an overnight survey undertaken in 2002 (Lim & Leong, 2016), or by more extensive surveys conducted in
2006 and 2008 (Chan et al. 2010).

Recent sighting records of five bat species from
Gunung Arong, Johor, Peninsular Malaysia

Identity of subject Fawn Roundleaf Bat (Hipposideros cervinus) (Mammalia: Chiroptera: Hipposideridae).

Location: Jalan Air Papan – Tanjung Resang, Gunung Arong Forest.

Habitat: Lowland, tall secondary forest.

Date and time: 26 March 2016, 20:00 hrs.

Description of record: An intact, freshly deceased Roundleaf Bat was found on the road shoulder of Jalan Air Papan – Tanjung Resang, a two-lane metalled road which dissects Gunung Arong Forest Reserve. The carcass had no visible evidence of injury or sickness. Measurements were taken as follows : head-body length 55.8 mm, tail length 26.0 mm, forearm length 50.5mm, tibia length 20.0 mm, ear height 13.9 mm.

Remarks: Based on the shape of the noseleaf , which has two lateral leaflets (with the intermediate leaflet narrower than the posterior noseleaf), and on the suite of measurements, this bat is identified as Hipposideros cervinus.

Hipposideros cervinus is common in primary, lowland dipterocarp forest at Krau Wildlife Reserve (KWR), Pahang, Peninsular Malaysia (Kingston et al, 2006). KWR is 230 km northwest of Gunung Arong. The range of this species is extensive: in addition to Peninsular Malaysia it also occurs in Sumatra, Java, Borneo, the Philippines, eastern Indonesia, New Guinea and Australia (Francis, 2008).

Indo-Pacific Humpback Dolphin (Sousa chinensis) at Air Papan, Johor, Peninsular Malaysia

Location: Air Papan Beach, Johor, Peninsular Malaysia.

Habitat: Coastal, shallow marine

Date and time: 03 June 2014, 18:45 hrs.

Description of observation: : A dead specimen, with an estimated total length of 2.0 metres, was observed floating in the sea, 100 metres from the beach. Over the next 30 minutes it was pushed towards the shore by wave action, and then finally coming to rest on the beach (Fig. 2.). A group of local people showed interest in the dead dolphin, but did not touch the body (Fig. 1).

Remarks: The subject is identified as Sousa chinensis based on the size and triangular shape of its dorsal fin, and on its relatively long, slender beak. The colour of this specimen is grey dorsally, and white ventrally: the species can vary considerably in colour from grey to pure white to pink, and can grow to 2.4-2.8 metres in length (Francis, 2008).

The specimen showed no obvious external injury, however a constant stream of blood was seen issuing from the corner of the mouth, suggesting it had only recently died from illness or trauma (Fig. 3.). The body appeared fresh, and exhibited no smell.

Sousa chinensis occurs in warmer waters of the eastern Indian and western Pacific oceans, as well as coastal waters in the South China Sea. Jefferson & Smith (2015) list the range countries as follows: Brunei, Cambodia, Indonesia (Sumatra, Java, Borneo), Malaysia, China, Singapore, Taiwan, Thailand and Vietnam (records from other countries are considered as unconfirmed or extralimital). Peninsular Malaysia therefore lies in the heart of the range of this species.

Air Papan is a sandy beach two kilometres in length facing northeastwards to the South China Sea. It is bounded by rocky headlands to the northwest and southeast. It is a popular holiday beach, with a profile that appears to be gently sloping.

Malay Civet (Viverra tangalunga) near Jemaluang, Johor, Peninsular Malaysia

Location: East Coast Highway at 257 km from Kuantan and 72 km from Johor Bahru, near Jemaluang, Johor, Peninsular Malaysia.

Habitat: Metalled road fringed by oil palm plantation and remnant freshwater swamp-forest.

Date and time: 21 October 2009, 09:20 hrs.

Description of observation: One example of about 50 cm head-body length was found on the side of the road, having apparently succumbed from collision with a vehicle. Hair was falling off the carcass, suggesting the
animal had been dead for more than a day.

Remarks: The Malay Civet is known to occur in both primary and disturbed forests up to 1100 metres elevation, and is also found in plantations and near villages adjacent to forest. This omnivorous animal is largely terrestrial and generally solitary in habits (Jennings & Veron, 2009: 212).
