So, what has caught my eye online today?

• Science Daily reports on a study of cleaner wrasse behaviour which looked at cooperation between cleaner wrasse pairs in servicing larger fish. At one point I was thinking about getting a cleaner wrasse for the tank which hold by moon wrasse, two maroon anemonefish, a bicolor angel and three humbug dascylluses, but apparently the cleaner wrasse is rather persistent in seeking food and will harass tank mates too much in a small tank. They also tend not to get enough to eat and often die early. I’m now holding off on cleaner wrasse until I have a really big tank with some big fish.
• Another Science Daily story discusses cooperation between spinner dolphins while hunting. “To match their 3,200-calorie-per-day diet, they need to eat at least 650 fish each night – plus enough extra to fuel the energy they burn during the hunt, perhaps another 200 to 300 fish.”
• Cairns’s Trinity Wharf, an old and rather dilapidated building on the south side of the City centre, is finally going to be upgraded to provide a decent arrival point for cruise ships. The existing facility really is awful. The upgrade is long overdue.
• Wired Science reports on a solar system 10.5 light years away that may have Earth-like planets. We still don’t have a means of observing Earth-sized planets at these distances, but future equipment should be able to do so. No reality TV broadcasts have yet been detected coming from the system, so intelligent life may be a possibility.
• At Scientific Blogging, Massimo Pigliucci has an interesting post up about the platypus genome and what it tells us about evolution.
