Octopuses Make Food for Weird Critters
In addition to humans, the octopus makes a meal for a wide range of animals. Some of its predators include sharks, eels, fish, and orcas. But it also provides nourishment for several parasites and “hangers-on”. And that’s only when it’s alive. Even when dead the octopus still provides food for many scavengers, big and small. Check out this cool article to learn more about the important role that the octopus plays in the marine food web.
Pakistan Hosts ‘First’ Dolphin And Whale Show
A maritime museum in Karachi, Pakistan is hosting its first marine mammal show this week. A beluga whale, a dolphin and a sea lion will perform for the public three times a day. The show was made possible by Russia’s growing role in the international trade of marine mammals — the beluga came from Moscow and the dolphin is on loan from Russia. The show has, of course, ignited yet another debate about keeping marine mammals in captivity.
Price of bluefin tuna falls at Tokyo auction
The celebratory first auction of the year at Tokyo’s Tsukiji market was held on Sunday. Sushi restaurateur Kiyoshi Kimura paid 7.36m yen (more than US $70,000) for a 230kg (507lb) bluefin tuna. This might sound like a lot of money for a single tuna, but it’s only five percent of what he paid at the auction last year (155m yen / US $1.7m). Kimura also set the record for highest bid in 2012. However, the high prices don’t always reflect high quality. Stocks of the Pacific, Southern and Atlantic bluefin tuna have fallen dramatically over the last 15 years, but demand continues to grow.
