Seahorses, pipefishes, ghost pipefishes and shrimpfish. Part 7 of my documentary, "Mucky Secrets", about the fascinating marine creatures of the Lembeh Strait in Indonesia.

In this video I take a look at members of the order Syngnathiformes, ray-finned fishes with long tubular snouts and elongate bodies.

The spotted seahorse, Hippocampus kuda, also known as the common seahorse, adapts its skin color to blend in to its environment. It has small hairs which gather algae and other matter to increase the camouflage. It feeds on small crustaceans, and its eyes can move independently to maximize its field of vision. It anchors itself to the seabed using its prehensile tail. The male seahorse incubates eggs then fetuses in a brood pouch on its belly until they are ready to hatch.

The tiny pygmy seahorse, Hippocampus bargibanti, is perfectly camouflaged amongst the branches of gorgonian seafans. Pygmy seahorses are so small and well camouflaged that they were only discovered in 1969 in a sea fan that had been collected by staff of an aquarium.

Pipefishes (Syngnathinae) are closely related to seahorses. They share the same long snout and toothless mouth, but have a straight body with ridges running along it. The ornate pipefish, Halicampus macrorhynchus, is well camouflaged to match its environment. The short-tailed pipefish, Trachyrhamphus bicoarctatus, resembles a gorgonian sea whip, and we see a translucent gorgonian shrimp, Manipontonia psamathe, standing on its back.

The banded pipefish, Dunckerocampus dactyliophorus, is a type of flagtail pipefish. The large, colorful tail fin makes it a faster and more agile swimmer than most other pipefishes and is used in courtship and territorial displays. Like seahorses, it is the male that incubates the young. Females compete to deposit their eggs in compartments under its abdomen. Scientists have suggested that the process of sexual selection continues after copulation. The males tend to fertilise and nurture the eggs of attractive females, while the eggs of less attractive females may be neglected or even digested by the male as he prepares for future pregnancies.

Ghost pipefish, family Solenostomidae, are usually found in pairs and are very highly camouflaged. Robust ghost pipefish, Solenostomus cyanopterus, are common in the Lembeh Strait, as are ornate ghost pipefish, Solenostomus paradoxus. We encounter a female ornate ghost pipefish churning her eggs between her pelvic fins to aerate them.

Finally we encounter a school of rigid shrimpfish, Centriscus scutatus, also known as grooved razor-fish, on a night dive.

There are English captions showing either the full narration or the common and scientific names of the marine life, along with the dive site names.

Squat lobsters, hermit crabs, true crabs and sea urchins. Part 3 of my documentary, "Mucky Secrets", about the fascinating marine creatures of the Lembeh Strait in Indonesia.

In this video we first look at more marine crustaceans. First we meet squat lobsters. The elegant squat lobster, Allogalathea elegans, lives commensally on the arms of crinoid feather stars. It feeds on plankton collected by its host, and its colour often matches the crinoid for camouflage.

Next we encounter squat lobsters of the Galathea genus fighting for territory on branching sponges at TK 2.

Hermit crabs don't have a hard carapace like other crabs, so they recycle an empty gastropod shell to protect their soft abdomen. They carry their adopted home around with them, and long eye stalks ensure that the crab has a wide angle of view. We encounter whitespotted hermit crabs, Dardanus megistos, living in empty cone shells and conch shells. We also meet an anemone hermit crab, Dardanus pedunculatus, carrying sea anemones on its back in a classic example of mutual symbiosis.

We then meet a pair of box crabs, Calappa sp.. The male box crab carries the female everywhere with him until she has moulted her shell and is ready to mate.

Camouflage is important for Lembeh's true crabs. We encounter a rear-spined elbow crab, Aulacolambrus hoplonotus, and a decorator spider crab, Achaeus sp., perfectly camouflaged in their environment.

A zebra crab, Zebrida adamsii, clings to the spines on the underside of a highly venomous flower urchin, Toxopneustes pileolus, using the last segment of its legs which has evolved into a hook.

Blue-spotted urchins, Astropyga radiata, are also highly venomous and gather in groups at dive sites such as Hairball. Juvenile emperor red snappers, Lutjanus sebae, often shelter amongst these sea urchins in a commensal relationship.

There are English captions showing either the full narration or the common and scientific names of the marine life, along with the dive site names.

Anemonefish, shrimps and mantis shrimps. Part 2 of my documentary, "Mucky Secrets", about the marine life of the Lembeh Strait in Indonesia.

In this video we take a look at the mutually symbiotic relationship between saddleback clownfish, a type of anemonefish, and the sea anemones found in the Lembeh Strait. The anemone's stinging tentacles provide protection for the clownfish, which are immune to the sting. The clownfish chase sway polyp-eating predators, and their feces provide food for the anemone.

We then see how partner shrimps (commensal shrimps) also benefit from a commensal relationship with sea anemones. The shrimps use the anemone's tentacles for protection, but the anemone doesn't appear to benefit in any way.

We then take a look at emperor shrimps and sexy shrimps (squat shrimps), then finally at mantis shrimps. A number of different species of spearing mantis shrimps and smashing mantis shrimps live in the Lembeh Strait. They all have extremely advanced eyes and a very fast attack with their claws.

There are English captions showing either the full narration or the common and scientific names of the marine life, along with the dive site names.

    [ Info ] Wannadive is safe! Hi, Firefox and Chrome users may experiment some difficulties in accessing Wannadive with their web browser. An ugly screen is telling Wannadive could provide malwares and not be safe!... Our ad server has been attacked Sept 15, and we did fix the problem a couple of hours later. Wannadive is now 100% safe. What still happen? Firefox and Google uses a database to track websites where malwares were detected. We ask Google to remove Wannadive from this database but it can takes a few hours/days? :-( Waiting for Google update, you can use a different web browser to access your favorite dive site atlas and community: Internet Explorer or Opera. Those browsers don\'t check Google\'s database. All the best, Wannadive team
