According to the Southern Metropolis Daily, a dwarf sperm whale (Kogia simus) was stranded at a beach in Daya Bay on the 23rd of May. The report stated that over a dozen people joined in the rescue effort, using their hands to spread seawater over the cetacean to help moisten its skin before pushing the animal to deeper water. The animal eventually swam away on its own.
Staff at the Daya Bay Fisheries Provincial Nature Reserve Management Office said that dwarf sperm whales are “very rare” in the waters around Daya Bay. The species is known to generally live in deeper water near the continental shelf. The animal was noted to have red blotches and scars indicating disease or parasites.
on the 12 of May 2016 I posted about a dwarf or pygmy sperm whale that washed up dead at Sao Wan Ho (Hong Kong), click here for the blog post and images.
Pictures published by Xinhuanet this week show a Chinese White Dolphin swimming in the San Niang Wan area of Guangxi, far west of Hong Kong.

A dolphin concern group published on its social media page that one chinese white dolphin (Sousa chinensis) and four finless porpoises (Neophocaena phocaenoides) were found stranded between Saturday the 17th and Monday the 19th of February. Autopsy scans found food remains in the dolphins, showing they were not starved to death. However, they showed multiple fractures. It is feared they were hit by motorboats as they had injuries on their heads and necks.
One finless porpoise was almost cut in half by what is thought to have been a boat propeller.
The adult Chinese white dolphin was found stranded at Mo To Chau. It was a 2.5-meter female, at least 10 years old, and with signs of choking, bone fractures and serious bone dislocation. The death of an adult female is a great loss to the species’ population growth, with numbers in Hong Kong down from over 120 some years ago to 47 at present.
In the past three years there have only been 3-4 stranded cetaceans in tyhe months of January and February. This year, more than 10 dead cetaceans have been discovered in the same period.
High-speed boats are always a big threat to dolphins and some might be hit by propellers and never be discovered. The Dolphin Conservation Society of Hong Kong (HKDCS) has urged the government to launch a speed restrictions on boats around dolphin and porpoise habitats or even ban them from entering these areas.
According to the HKDCS only one new-born Chinese white dolphin was recorded last year. With the loss of another adult female dolphin, there is a dwindling chance of recovery of the local population.
A HK fishing groups social media account has reported a finless porpoise (Neophocaena phocaenoides) being freed from a floating fishing net on the 18th of February.
It’s not clear who the net belonged to and how long the animal was trapped in it.
According to Around DB magazine a porpoise was found stranded at Palm Beach (presumably Cheung Sha Beach) on the 26th of October (2017). Judging from the images the dead animal looks to be a finless porpoise (Neophocaena phocaenoides) and about 120 cm in length (adult).
Xinhua reported on the 22nd of July (2017) that a rare rough-toothed dolphin (Steno bredanensis), named Jiangjiang, was released back to sea earlier this week, two months after it beached itself and was rescued in Guangdong Province.
The 2.2-meter male dolphin was found stranded on the coast of Heisha Bay near the city of Jiangmen (200 km west of Hong Kong) on May 3. It was suffering breathing troubles, according to Yang Naicai, a vet who joined the rescue operation.
Rescuers checked the dolphin’s breathing, gave an injection of antibiotics, and provided food and medicine to help it regain its strength.
The animal was housed in a pool designated for dolphin rescue at the Pearl River Estuary Chinese White Dolphin National Nature Reserve.
“We maintained round the clock monitoring, hoping for a miracle,” said Chen Hailiang, from the reserve.
The dolphin, which weighs around 100 kg, was released back to the sea on Thursday as its physical condition had returned to normal.
Although the rough-toothed dolphin, a national second class protected species, can be found in deep tropical, subtropical and temperate waters around the world, it is a rare visitor to Chinese coastal waters.
In 2014, a rough-toothed dolphin stranded in Guangdong died despite rescue efforts.
A Chinese white dolphin (Sousa chinensis) was found dead on the morning of the 19th of July (2017) floating in the sea near Cheoc Van beach in Coloane.
Local animal rights group Anima (Macau) was alerted to the presence of the deceased animal by a concerned citizen. Anima president, Albano Martins, speculated that the dolphin may have collided with a maritime vessel in the Pearl River Delta estuary.
The Anima president also said that Macau’s Marine and Water Bureau has retrieved the deceased animal and is arranging for the body to be disposed.
Sightings of dead dolphins off the coast of Macau are a relatively rare occurrence, but several have been documented in recent years.
