European jackal
The European jackal is the largest of the golden jackals, with animals of both sexes measuring 120–125 cm (47–49 in) in total length and 10–13 kg (20–29 lb) in body weight. One adult male in North-Eastern Italy is recorded to have reached 14.9 kg (33 lb). The fur is coarse, and is generally brightly coloured with blackish tones on the back. The thighs, upper legs, ears and forehead are bright reddish chestnut. Jackals in Northern Dalmatia have broader than average skulls, which is thought to result from human induced isolation from other populations, thus resulting in a new morphotype.
Tille trevally
The tille trevally is a large species, growing to a maximum known length of 80 cm and a recorded weight of 7.3 kg. It is similar in general appearance to most jacks in the genus, having a compressed, oblong body, with the dorsal profile more convex than the ventral profile, particularly anteriorly. This curvature gives the fish a discernibly 'blunt' head and steep snout, which is the most obvious identifying feature of the species. The dorsal fin is in two distinct sections; the first consists of eight spine and the second of one spine and 20 to 22 soft rays. The anal fin consists of two anteriorly detached spines followed by one spine and 16 to 18 soft rays, while the pelvic fins have one spine followed by 18 soft rays. The lateral line is moderately arched anteriorly, with 53 to 54 scales in this section, while the straight section contains none to two scales and 33 to 42 strong scutes. The breast is completely scaled. The species has well-developed adipose eyelids, while its dentition consists of an outer row of widely spaced canines and an inner band of villiform teeth in the upper jaw, with a row of widely spaced conical teeth on the lower jaw. The tille trevally has 22 to 25 gill rakers and 24 vertebrae.
