  • This is the pectoral fin of a 12.8m female Bryde’s whale (Balaenoptera edeni brydei) that appeared to have been brought into port on the bow of a ship. Though the cause of death was not entirely clear, the ship was known to have traveled for four to five days from China to Thailand. The whale could have died from impact, as suggested by the broken pectoral fin shown here. The whale was covered with bite marks from cookie cutter sharks, indicating that it was probably not one of the Gulf of Thailand’s resident Eden’s whales.

  • This is an adult pygmy blue whale (Balaenoptera musculus brevicauda) entangled in a fishing net. The net was wrapped around the base of the whale's fluke, with substantial net and rope trailing behind. As is visible in this image, rope stretched up both sides of the whale and appeared to be caught in the whale's mouth. I came across this whale in shallow, green, murky water, approximately 60 meters depth. The whale was still able to swim, though it appeared exhausted. It did not fluke, and the netting was not visible from the surface. Sadly, this whale most likely died shortly after this encounter.

  • This sequence of 17 images shows a humpback whale (Megaptera novaeangliae australis) executing a forward breach. As the whale emerges from the ocean, water streams off the animal’s body, as well as from the sides of the whale’s mouth. The whale exhales with great force as it surfaces, creating a cloud of water vapor, then inhales through open nostrils before plunging back into the water. The entire sequence spans just over one second of time. Image 3 of 17.

  • This is a male Eden’s whale (Balaenoptera edeni edeni) known as Mesa, demonstrating the Drawbridge technique for feeding on anchovies. The whale raises his head above water to approximately eye level, then drops his lower jaw rapidly as if lowering a drawbridge. He then maintains a stationary, mouth-open position for an extended period of time, sometimes up to 30 seconds, during which time anchovies jump into his mouth. When he collects sufficient fish, he closes his mouth and reenters the water. Mesa is part of an isolated population of Eden’s whales, which are a neritic member of the Bryde’s whale complex, that live in the shallow waters of the Gulf of Thailand. It is likely that there are 50 or less in the population. Photo 7 in sequence of 7 photos illustrating beginning of Drawbridge technique.

  • This is a young Eden’s whale (Balaenoptera edeni edeni) in the Gulf of Thailand side-lunging through a mass of fish, likely Sardinella sp., that this whale and its mother had aggregated by swimming in a large circle. This circle and side-lunge technique has become the dominant foraging technique since 2017, replacing the open-mouth trap feeding strategy that had been prevalent since the 1990s. I believe this reflects a change of target prey. The whales adapt their foraging strategies to target species.

  • This is milk that escaped from the mouth of a female humpback whale calf (a very white one that I nicknamed Snow White) after nursing from her mother. Calves often open their mouths and appear to gulp water after they nurse, possibly to flush excess milk. Note that the milk was thick and coagulated in the seawater. This makes sense, as the milk has a high fat content in order to support the high caloric demand of a growing calf.

Calf #14 was one of the injured calves, with multiple wounds that may have been inflicted by a pod of marine mammals, possibly false killer whales (Pseudorca crassidens). I had nine encounters with this mother and calf over a period of 33 days. During that period, a male escort was with them for at least 14 days. The female, calf, escort group traveled from Vava'u to Toku Island and back to Vava'u.

  • These four humpback whales were part of a heat run comprising six testosterone-fueled males in pursuit of a single fertile female. Swimming at high speed, the whales appeared from the blue haze below, charging toward the surface in a mad rush. I dived down and waited in mid-water for them. <br />
<br />
As this group of four hurtled past me, I experienced a surge of adrenalin, triggered by the simultaneous exhilaration and apprehension of such a close encounter with a quartet of 40-ton animals. <br />
<br />
The four whales pictured here are all male, one of which is blowing bubbles--a common behaviour that may signify aggression when observed during heat runs. <br />
<br />
The female surfaced some distance away together with the other males, which certainly explains why these whales were in such a rush!

  • This is the view from beneath a male humpback whale calf (Megaptera novaeangliae) playing at the ocean surface. The calf had just lifted its caudal region out of the water, then flipped over so that his belly was facing upward while he spun his body around. This had the effect of whipping his fluke in a circle, leaving a wake of bubbles, froth and whitewater as seen here. This type of play behavior is typical among healthy humpback whale calves.

  • Four bowhead whales (Balaena mysticetus) swimming together. These individuals were part of a large social gathering of the endangered Sea of Okhotsk subpopulation.

  • This bowhead whale (Balaena mysticetus) is a part of the endangered Sea of Okhotsk subpopulation, with population estimates in the low hundreds. This individual was turned upside-down while performing loud percussive slaps on the ocean surface with the dorsal surface of its fluke. Orca rake marks are visible on the corners of the whale’s fluke. The whale was part of a large social gathering, comprising well over 50 whales. This whale’s tail slapping could be heard for a long distance. When this whale stopped, the gathering dissolved, with whales breaking moving away as singles and in smaller groups.

  • This North Pacific humpback whale (Megaptera novaeangliae kuzira) was part of a group of whales that engaged in cooperative bubble-net feeding for several days. One morning, this whale breached multiple times, prompting the other whales in the group to breach and pectoral slap for an extended period of time, as they ended their social foraging behavior and the whales went their separate ways.

  • This humpback whale was part of a bubble-net feeding group in Icy Strait, Alaska. This breach was one of a series of breaches and pectoral slaps that occurred in tandem with the end of social foraging, with the whales going separate ways.

  • Breaching humpback whale (Megaptera novaeangliae australis) demonstrating incredible power as it launches itself from the ocean

  • This sequence of 17 images shows a humpback whale (Megaptera novaeangliae australis) executing a forward breach. As the whale emerges from the ocean, water streams off the animal’s body, as well as from the sides of the whale’s mouth. The whale exhales with great force as it surfaces, creating a cloud of water vapor, then inhales through open nostrils before plunging back into the water. The entire sequence spans just over one second of time. Image 17 of 17.

  • This is an adult female humpback whale that repeatedly held her fluke above the surface of the ocean while resting in a head-down position, such that her body was oriented vertically in the water. There was significant peeling or shedding of skin from the fluke’s dorsal surface, as seen in this photo. Though the peeling was most likely due to normal sloughing off of skin, it was reminiscent of how human skin peels when sunburned. I speculate that another possibility could be that the whale may have had sunburn as a consequence of her resting behaviour. Date of encounter was 18 August 2017. See separate detail photograph of skin recovered from the fluke of this whale.

  • This is a piece of skin that was shed from the dorsal surface of the fluke of a female humpback whale. The whale repeatedly held her fluke above the surface of the ocean while resting in a head-down position, such that her body was oriented vertically in the water. There was significant peeling or shedding of skin from the fluke’s dorsal surface, most likely due to normal sloughing off of skin. I speculate that another possibility could be that the whale may have had sunburn as a consequence of her resting behaviour. Note the pattern of the skin. Date of encounter was 18 August 2017. See separate photos of fluke above water.
