Short-Finned Pilot Whale:
There are currently two recognized species of pilot whale, the short-finned and long-finned. In Japan, there are two morphologically and geographically distinct populations of short-finned pilot whales, one northern and one southern. It is believed that they are in fact separate subspecies however further examination is required.
Pilot whales are large, robust animals with a bulbous head and no discernible beak. The flippers are long with a pointed tip, though in the short-finned form they are more curved, slightly shorter and the ‘elbow’ is less defined than in the long-finned form. The dorsal fin is set forward on the body and varies in shape depending on age and sex. The tail flukes also have sharply pointed tips plus a distinct notch in the middle and concave edges. The short-finned pilot whale is jet black or dark grey with a grey or white ‘saddle-patch’ over its back behind the dorsal fin. It has a grey or almost white anchor shaped patch on its chest and a grey or white stripe which goes diagonally upwards behind each eye. Male short-finned pilot whales are on average 5.5m in length & weighing up to 3,000kg, whereas female short-finned pilot whales on average are 4.3m in length & weighing up to 1,500 kg. Males are thought to live to be about 45 years of age whilst females are thought to survive into their 60’s.
Short-finned pilot whales are highly sociable and are rarely seen alone. They are found in groups of between 15-50 animals, though some pods are as large as 60 individuals. Super-pods of hundreds of individuals are not uncommon and may swim abreast in a line several miles across with adults occasionally porpoising when swimming fast. They are sometimes seen logging and will allow boats to get quite close. They rarely breach, but may be seen lobtailing, spyhopping and surfing in the wake of large waves. Short-finned pilot whales have a preference for water about 1000m deep and are often found on continental slopes where their main prey item, squid is abundant. The typical diet of the short-finned pilot whale appears to consist of squid and fish, as well as other cephalopds, such as octopuses. However the short-finned pilot whales have been reported to harass sperm whales and dolphins, so marine mammals may also be included in their diet. This species usually feeds at night, making deep dives in search of prey.
Their highly social nature and strong familial bonds could explain why this species is amongst those cetaceans that most frequently mass-strand. The short-finned pilot whale live in a matri-lineal or female based society and females have been known to care for a calf that is not their own. After weaning, young male short-finned pilot whales may move to a new group, whereas the females tend to stay in the pod to which they were born. The name “pilot whale” comes from an early idea that these pods are piloted by a leader, typically known as the matriarch.
The worldwide population of short-finned pilot whales is unknown and although they are not thought to be threatened on a global scale, several populations are hunted. Targeted in Japanese drive fisheries, in the Faroe Islands The Grind, and other hunts elsewhere. The short-finned pilot whale is also favoured as a display species in aquariums around the world. Other threats to the species include entanglement in fishing nets and noise pollution. The IUCN lists the species as Data Deficient.

In Taiji: 2017/2018 Taiji Drive hunt quota allows for 101 Short-Finned Pilot Whales
The first drive hunt in Taiji this season was a nursery pod (mainly mothers and their calves) of short-finned pilot whales on September 3, 2017.
In some instances a drive can last for almost an entire day and for hour after hour the dolphins are relentlessly chased. In those long hours of pursuit, while the dolphins are driven towards the cove, the brutal reality of the hunts is driven home – No matter the species, the hunts are torture for dolphins. Kept in a continuous state of “fight or flight,” vast amounts of energy are mobilized as the pod attempts to evade the hunters.
And for seven hours on September 3, 2017 the first pod of pilot whales this season, fought for their lives, struggling against the deafening sounds of boat engines, of poles being banged (designed to confuse the dolphins’ sensitive navigation systems) and the sheer willpower of the hunters themselves. By early afternoon, it became clear the dolphins were losing the battle. Their swimming became noticeably slower, and several times the pod refused or were unable to move. However with the boats so close to the pod, they had no choice but to keep moving, ultimately swimming right into the cove.
Boats and skiffs quickly left the cove, leaving the pod alone for the rest of the day and night. Many juveniles were seen in the pod, huddled close to their mothers. Little heads bobbed up and down while the adults continued to circle the tightly-knit group. The scene was horrifying, for, unlike the dolphins who are unaware of their fate, we have a good idea of the atrocities that will unfold tomorrow.
On the second day, 10 pilot whales were slaughtered and 3 juveniles were taken for captivity. The remaining pilot whales were kept for a second night. Exhausted and terrified, missing 13 pod members. Their fate would be determined the following morning. On Day 3, after slaughtering 10 more today (not including 1 that was floating in the bay all day) the hunters rushed out to attempt another drive leaving the remaining juveniles in the cove. Eventually they released the young Pilot whales and all boats returned empty handed.
A total of 21 dead Pilot whales and 3 taken for captivity, over the course of 3 days. These images below are proof of the cruel nature of the captivity industry. Trainers who claim to love and care for these animals remain under the tarps while the hunters slaughter those the trainers do not want. We can all put a stop to this by helping everyone connect dolphin shows with these horrifying slaughters.
