  • A large sea spider brought up in a fishing net from a depth of 300 to 400 meters in Suruga Bay off the west coast of the Izu Peninsula, Japan. The sea spider was alive and active, crawling back toward deep water when I released it.

  • Adult female sperm whale executing a playful flick of her fluke just before diving down to deep water, perhaps to forage for food. This whale was part of a larger group of 15 to 20 whales that were traveling together across a wide range, spening a lot of time at the surface between dives. The whale's powerful caudal area is clearly visible in this image, as are the unique markings on her abdominal region. These markings make it possible to identify individual whales.

It is one of many species of the king crab genus Paralomis. This juvenile was about 7cm in size. It was brought up from a depth of 1000m in Suruga Bay, Japan. The Japanese name is Ezo-Ibarabani.

  • This is a calico frogfish (Fowlerichthys scriptissimus) with a zebra-striped pattern. This body pattern is relatively rare compared to the more common mottled pattern. This species usually lives in waters 70m and deeper. The fish appears in shallower sometimes during winter months, perhaps for reproductive purposes.

  • This is a dead mature female Ancistrocheirus lesueuri squid, which is a mesopelagic cephalopod living in the range of 200 to 1000 meters depth. This specimen was found at the surface, floating upside down as pictured here. There are photophores visible on the ventral surface (facing up) and hooks on both clubs of the feeding tentacles. This squid is an important part of the diet of sperm whales in the southern hemisphere. There were many sperm whales in the area when this was photographed. This species is ammoniacal, meaning it stores ammonia ions in the arms, head and mantle tissue for buoyancy. Why this specimen would only float upside-down is unclear. Perhaps the ammonia (which is lighter than sea water) was the cause. This specimen was 40cm to 45cm.

  • Dead blue whale (Balaenoptera musculus) floating at the ocean surface. This whale was most likely killed by a ship strike that took place in the shipping lanes just south of Sri Lanka. Container ships and other large boats use these shipping lanes day-in and day-out. The shipping lanes are situated in the middle of feeding grounds for blue whales and other cetaceans, which dive down to deep water to forage for krill and other food. Photo taken under permit.

  • This is blue whale feces, discharged by a whale that had surfaced after feeding on krill in deep water in southern Sri Lanka. The neon red-orange color of the defecation is due to the whale's krill-based diet. The feces dissolve rapidly, as is apparent from the fizzing around the large clumps in this image.

  • This is the genital slit of a dead blue whale, found floating south of Mirissa in Sri Lanka. The tip of the whale's penis appears to be protruding from the animal. The whale was most likely struck by one of the many container ships in the busy shipping lanes that coincide with the feeding grounds of blue whales and other cetaceans in the area. Other photos of this whale show a deep scar in the whale's caudal area, suggestive of a direct bow strike by a large commercial ship. Photograph taken under permit.

  • This is a Stichaeus grigorjewi, sometimes called a long shanny or northern blenny. It is a deepwater species that resides down to depths of around 300 meters in the Sea of Japan and Sea of Okhotsk. Females come up to shallower water to lay eggs. This fish is edible, but the eggs contain a toxin called dinogunellin, which can cause vomiting, nausea, abdominal pain, diarrhea and other unpleasant symptoms if ingested. There are no recorded cases of deaths from consumption of eggs. As pictured here, the fish repeatedly extended and retracted a long, twisted, multi-pronged tongue-like appendage reminiscent of the lure used by stargazers (Uranoscopidae) to attract prey.

This one washed up during a mass stranding of thousands of Physalia utriculus amd other animals of the open-ocean, pelagic community. Attached to the shell were pelagic goose barnacles (Lepas sp.).

  • This is a pair of tri-spine horseshoe crabs (Tachypleus tridentatus) walking across the ocean bottom in shallow water just prior to spawning. The smaller male uses modified legs (pedipalps) to grasp onto the female in front. The female has just started to burrow into the substrate, a process which involves digging deep enough to bury the front part of her body (Prosoma) and much of her abdominal area (Opisthosoma) as well. When she eventually reaches acceptable depth and deposits eggs, the male will fertilize them. Females often deposit several clutches of eggs in the same general area before moving on to do the same in different locations.<br />
<br />
Note the gastropod riding on the female’s head. Shells, barnacles and other similar passengers seem relatively common on these horseshoe crabs.<br />
<br />
Although these animals are called crabs, they are not members of the Subphylum Crustacea. They belong to a separate Subphylum—Chelicerata—which also comprises sea spiders, arachnids, and several extinct lineages such as sea scorpions. The earliest known fossils of horseshoe crabs date back 450 million years ago, qualifying these animals as living fossils, as they have remained largely unchanged.<br />
<br />
Tachypleus tridentatus is the largest of the four living species of these marine arthropods, all of which are endangered.

  • This is part of competitive heat run with at least 14 humpback whales, far, far out in the open ocean. The seas were rough, and whales spread out over a large area. Pictured here is one whale down deep in the process of inflating his throat. This is often a precursor to blowing a stream of bubbles as a dominance display. In this instance, however, this whale was not the primary escort, and it eventually deflated its throat instead of blowing bubbles. Why it inflated and then deflated is not clear.

  • A family of sperm whales (Physeter macrocephalus) resting at the ocean surface, with the lead female holding Architeuthis giant squid in her mouth. There was a calf in this family group that was unable to dive deep for extended periods of time with the adults. It is possible that the adults were teaching the calf to consume giant squid, as the family group played with the squid for an extended period of time, with the whales shredding the squid to pieces in the process. Photographed in Ogasawara, Japan.

  • Leftover piece of a deep-water seven-arm octopus floating at the ocean surface in Ogasawara, perhaps remnants of predation by sperm whales or other toothed cetaceans. The octopus has eight arms, but the hectocotylus (a specially modified arm used in egg fertilization) is coiled in a sac beneath the right eye. Due to this species' thick gelatinous tissue, the arm is easily overlooked, giving the appearance of having only seven arms.
