Whale sharks are easy. Basking sharks are hard. Whale sharks usually inhabit warm, tropical waters, while baskers prefer cooler, temperate regions.

I had dived in Makako Bay, Hawai’i, many times over many years without seeing a single knobby sea star. The first time I encountered one, however, it wasn’t just one, but more than a hundred of them together. They were all gone a day later, and I haven’t seen one since.

A few white southern right whales are born each year, but this leucistic trait is not a permanent feature. Their coloration usually gives way to a lighter gray in adulthood, indicating they were white at birth and distinguishing them from the more common darker whales.

Le dragon de mer commun (Phyllopteryx taeniolatus) n’a rien de commun. Présent uniquement dans les eaux côtières tempérées de l’Australie, ce spectaculaire parent de l’hippocampe —également appelé dragon de mer feuillu— peut atteindre 45 centimètres de long. Il arbore de magnifiques couleurs et d’élégantes excroissances cutanées en forme de goutte.

Like many octopuses, the female greater blue-ringed octopus (Hapalochlaena lunulata) is a semelparous animal, which means she reproduces once and then dies.

While photographing the wrecks throughout the day, I noticed a few wobbegong sharks, but they were difficult to photograph as they rested under ledges or in sheltered spots.

Chaque année, les baleines à bosse quittent leurs aires d'alimentation de l'océan Austral pour rejoindre les îles Australes, où elles viennent mettre bas et élever leurs petits dans les eaux abritées autour de Rurutu. Les observateurs peuvent ainsi y étudier leurs comportements naturels sans pratiquement les perturber.

The Australian sea lion (Neophoca cinerea) is the only pinniped endemic to Australia.
