| 説明 | For Hector's dolphin's on the Black Cat in Akaroa harbour, day two of my friends visit from London. I took them over the Port hills to Akaroa. We had such a beautiful day and they enjoyed the trip.The cruise is packed with highlights including the rare, NZ native dolphin - the Hector's Dolphin, as well as penguins and other sea birds. And you'll see giant volcanic sea cliffs and hear about Akaroa's fascinating past. Cruises depart every day, weather permitting.The Back Cat is modern catamaran, the 60 foot /20 metre Black Cat (previously the Canterbury Cat), is perfect for viewing the natural wonders of Akaroa Harbour. For More Info: www.blackcat.co.nz/akaroa-harbour-nature-cruises.htmlHector's dolphin (Cephalorhynchus hectori) is the best-known of the four dolphins in the genus Cephalorhynchus and is found only in New Zealand. At approximately 1.4 m in length, it is one of the smallest cetaceans, and New Zealand's only endemic cetacean.Hector’s dolphin is the smallest of the dolphins. Mature adults have a total length of 1.2–1.6 m (3 ft 10 in–5 ft 3 in) and weigh 40–60 kg (88–130 lb). The species is sexually dimorphic, with females being slightly longer and heavier than males. The body shape is stocky, with no discernible beak. The most distinctive feature is the rounded dorsal fin, with a convex trailing edge and undercut rear margin.The overall appearance is pale grey, but closer inspection reveals a complex and elegant combination of colours. The back and sides are predominantly light grey, while the dorsal fin, flippers, and flukes are black. The eyes are surrounded by a black mask, which extends forward to the tip of the rostrum and back to the base of the flipper. A subtly shaded, crescent-shaped black band crosses the head just behind the blowhole. The throat and belly are creamy white, separated by dark-grey bands meeting between the flippers. A white stripe extends from the belly onto each flank below the dorsal fin.At birth, Hector’s dolphin calves have a total length of 60–80 cm (24–31 in) and weigh 8–10 kg (18–22 lb). Their coloration is the same as adults, although the grey has a darker hue. Four to six vertical pale stripes, caused by fetal folds affecting the pigmentation, are present on the calf’s body until an age of about six months.For More Info: en.wikipedia.org/wiki/Hector%27s_dolphin |
