• A Heart as Big as a Whale

    A Heart as Big as a Whale0

    This is a replica of a blue whale heart, life-sized. An adult can crawl through it with little difficulty. The replica is on display at the Museum of New Zealand Te Papa Tongarewa. Since a real blue whale heart has never been recovered from a dead whale, the builders had to rely on whaler’s records,

  • Nudibranch’s Colorful Defense

    Nudibranch’s Colorful Defense0

    Most sea-dwellers evade predators by camouflage, a hard shell, or very fast responses. So, it would seem that the thousands of nudibranch’s (or “sea slugs”) wouldn’t have a chance; they’re brilliantly colored, slow and soft.

SAM, the Sample Analysis at Mars, is a scoop that had previously been using its instrumentation to search for methane, produced by life on Earth, in Mars’

  • Ocean’s Crown of Thorns

    Ocean’s Crown of Thorns0

    The tropical Pacific and Indian oceans are home to an unusual sea star. The Crown of Thorns (COT) lives by crawling over coral reefs, eating coral polyps as it moves along. It’s almost too successful: the sea star is one of the things wreaking devastation on Australia’s Great Barrier Reef. Populations of the star are
