  • 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.

  • When female Pteromys volans orii squirrels go into estrus, there is usually a primary male with her. He fends off challengers and does his best to monopolize copulation opportunities. Females will mate with other males when the opportunity arises however. Here, the female has snuck out to copulate with another male. The primary male has just realized what is happening and has rushed out of the den to confront the interloper.

  • This is a Pteromys volans orii flying squirrel defecating, having assumed a comfortable seated position at the entrance of its nest for the purpose.

  • This is a male Japanese dwarf flying squirrel (Pteromys volans orii). This sub-species of Siberian flying squirrel, found only in Hokkaido, Japan and known locally as ezo-momonga, is primarily nocturnal. This imdividual was active during the day because it was competing for the attention of a female in oestrous. The squirrel’s paddle-like tail is visible from this angle, flopped over its back. This animal uses its tail somewhat like a rudder during flight, helping to adjust direction.

  • This is a Japanese dwarf flying squirrel (Pteromys volans orii) grooming itself while resting in a tree in the golden light of late afternoon. Although this species is primarily nocturnal, individuals occasionally emerge from their nests during daylight hours.

  • A female Japanese dwarf flying squirrel (Pteromys volans orii) in oestrus often attracts the attention of more than one male. When that happens, males chase one another, leap from and glide among trees, and sometimes engage in physical skirmishes. The male in the background of this image is stalking the male in the foreground in an attempted sneak-attack during one such contest for an eligible female.

  • 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.

  • 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.

  • During summer months, bowhead whales (Balaena mysticetus) like the one pictured here often visit shallow water, which provides a shelter from potential predation by orcas. As seen in this photograph, the whales can swim in water that is only just deep enough for them not to become stranded. This individual is a member of the endangered Sea of Okhotsk subpopulation.

  • 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 a female humpback whale calf (Megaptera novaeangliae australis) swimming together with her mother at depth, ventral surfaces of both whales clearly visible. The proximity of the calf to mother and similarity of body language underscores the bond between the two. This mother and calf were accompanied by at least three escort whales in a dynamic situation.
