  • This is a male humpback whale calf (Megaptera novaeangliae) with his mother. The calf had just finished nursing and was making its way to the surface to breathe. While still at depth, the calf opened and closed its mouth several times. This behavior often happens during or after nursing.

  • Humpback whales (Megaptera novaeangliae) in Chatham Strait, Alaska emerging from the water with their mouths wide open to feed on schools of fish. There are fish, probably herring, visible in the photo. From this angle, there is a clear view of the baleen hanging down from the top of the humpback whales' mouths.

  • This is a striated frogfish (Antennarius striatus) with its mouth open, providing a clear view of the inside of the fish's mouth. The fish's mottled body pattern and its dermal spinules (which resemble hairs), provide the frogfish excellent camouflage.

  • This is a view down the throat of a male Zoarchias major eelpout that has opened its mouth during a confrontation with another male. When the males square off with one another, the size of each male’s mouth plays a role in establishing dominance. It may be possible that the pattern inside the mouth is used for displays, threats and other communication as well. Deep inside the throat are teethlike structures facing toward the rear, quite likely serving to make escape difficult for prey.

  • Adult female sperm whale (Physeter macrocephalus) at the ocean surface with her mouth open. This whale has just surfaced from foraging in deep water. There is a small piece of squid on the tip of her lower jaw. She has many visible scars left by the suckers of Architeuthis sp. giant squid, which seem to be among the primary prey hunted by sperm whales in the waters of Ogasawara (the Bonin Islands) in Japan.

  • Two mature male Zoarchias major eelpouts opening their mouths as wide as possible during a protracted confrontation. From personal observation, it seems likely that the size of the mouth when wide open serves as a means of relative strength comparison. This type of behavior is exhibited during the spring and summer months, presumably associated with reproduction.

  • This is a male fat greenling (Hexagrammos otakii) opening his mouth, which is a behavior that many fish exhibit. This individual was watching over several clutches of developing eggs, which were situated behind the fish and thus obscured from view in this image.

  • Two male Zoarchias major eelpouts with mouths wide open facing off in the middle of Sargassum hemiphyllum algae. The fishes blend-in well with both the coloration and texture of these brown algae and other surrounding vegetation and substrate, providing some measure of protection in the form of camouflage from larger fish patrolling the reef.

  • This is a female Zoarchias major eelpout approaching another one that has occupied a hole in the reef. The aggressor has clamped her mouth on the occupying fish in an attempt to intimidate and force her out of the hole. Individuals of this species engage in such battles over holes while they are in shallow waters. Females and males alike intimidate both females and males in a continual process of claiming and losing holes. The holes themselves are often those used by blennies, which have been displaced by these fish, but return to the holes once these fish disappear. The purpose of these battles is not clear.

  • A group of humpback whales (Megaptera novaeangliae) engaged in cooperative foraging behavior commonly referred to as bubble net feeding. The whales find and encircle schools of fish, blowing bubbles as they do so to create a net around the fish and drive them to the surface. The whales then surround the fish and charge up in unison through their prey with mouths wide open. By working together, the whales are able to herd large schools of fish that would be more challenging for a single whale to capture. Photograph taken in Chatham Strait, Alaska.

  • Two male Zoarchias major eelpouts engaged in competitive battle, mouths wide open. The fish on the left is ensconced in a hole in the coral, while the challenging fish on the right is fully exposed in the water column. These fish, called ookazunagi in Japanese, engage in this behavior during the spring and summer, presumably as part of their reproductive process. Despite these confrontations, it does not appear that the fish inflict harm on one another.

In this image, the frogfish's illicium (rod) and esca (lure) are folded back and tucked away on top of the fish's head, comprising the front-most of three dorsal fins. The white hair-like protrusions on the fish's body are small amphipods known as skeleton shrimp (Caprellidae). This photograph was taken three days prior to this fish spawning with a smaller female.
