Fishing trophies, back in the day
by Peter Etnoyer in Deep Sea News
What better way to get at the question of recreational fishing impacts to ocean wildlife than to study historical pictures of the day’s catch on the docks at Key West, Florida? The American island paradise is legendary, frequented by Ernest Hemingway and other huntsmen since the early 1950’s.
Trends in the size and types of trophy [...]... Read more »

Friday Deep-sea Picture: Sea cucumber stampede
by Peter Etnoyer in Deep Sea News
Boggling bioturbators, Batman. It’s a wild herd of holothurians. Run for yur lives! Elasipodid holothurians are a dominant component of the mobile invertebrate megafauna on the Porcupine Abyssal Plain, northeast Atlantic. They occur in high densities over large areas (Smith et al. 1997).
Yes, but, where are they going? They’re up to something, for sure, never [...]... Read more »

Gigantothermy: Size Matters
by Peter Etnoyer in Deep Sea News
by Bryan Wallace for Deep Sea News
When you think of cold marine environments, you probably think of blubber-wrapped seals, whales, and walruses, big, furry bears, or a huddled mass of penguins. What do those animals have in common? They are endotherms, their body temperature maintenance depends on consistently high levels of heat generated (and retained) [...]... Read more »

Friday Deep-sea Picture: Basking Shark
by Peter Etnoyer in Deep Sea News
Basking sharks can measure 35 feet or longer, are known to live in temperate waters around the world, but their wintering grounds were unknown until very recently. Discovery News reports that satellite tags placed by Greg Skomal of Massachusetts Marine Fisheries are bringing new revelations about these mysterious animals. Five basking sharks swam more than [...]... Read more »

Deep-diving adaptations of Leatherback turtles
by Peter Etnoyer in Deep Sea News
An article by Bryan Wallace for Deep Sea News.
The deep-sea is as far removed from atmospheric oxygen as anyplace on Earth, but a select few air breathers are undeterred. (No, I’m not referring to intrepid deep-sea human researchers.) These extraordinary critters frequently venture into the deep-sea, despite their vital link to air the above the [...]... Read more »

Deep-corals are world’s oldest animal
by Peter Etnoyer in Deep Sea News
It hasn’t been too long since Brendan Roark first reported that deep-sea corals off Hawaii are clocking in as the world’s oldest animal. At four thousand years old, the Leiopathes sp. black corals beat the quahog clams, which live to be four hundred, and they beat the tortoise Jonathon, who’s 176. Of course, these deep-sea [...]...

Finding Nemo by DNA parentage analysis
by Peter Etnoyer in Deep Sea News
Since the first observations of transoceanic dispersal in marine snails (Scheltema 1971), long distance transport for marine animals has been a kind of Holy Grail for marine conservation science. Marine protected area (MPA) networks make sense to coral lovers, for instance, because most coral reef fish have pelagic larval durations exceeding 30 days. Lobster larvae [...]... Read more »

World’s oldest animal captured alive, on video
by Peter Etnoyer in Deep Sea News
Deep Sea News has been following the story of the world’s oldest living animals, the deep-sea Leiopathes black corals and Gerardia gold corals from 300m depth in hawaii. Both are zoantharian or “zoanthid corals” that excrete a strong proteinaceous axis. The branches of these corals suggest gold coral colonies can be as old 2700 years, and [...]... Read more »

Bacterial assemblages in deep Lophelia coral
by Peter Etnoyer in Deep Sea News
DSN friend and colleague Dr. Christina Kellogg published a new paper this month characterizing the bacterial assemblages of deep Lophelia pertusa coral in the Gulf of Mexico.
Two Lophelia-specific bacterial groups were identified: a cluster of gammaproteobacteria related to sulfide-oxidizing gill symbionts of seep clams and a group of Mycoplasma spp. The presence of these groups [...]... Read more »

Friday Picture: Have your coral and eat it, too?
by Peter Etnoyer in Deep Sea News
People accept the idea of echinoderm predation on shallow reef building corals. The voracious Crown of Thorns seastar Acanthaster planci is a familiar coral antagonist on the Great Barrier Reef, part of a natural process that may or may not be amplified by anthropogenic disturbance. Asteroid predation on deep-sea corals is more difficult to demonstrate. [...]... Read more »
