For Hoff Yeti Crabs Food, Sex, and Birth Determine Living Space At Vents  

Within just a few short centimeters the temperature drops from 350?C to -1.5?C (692 to 29.3?F). At 2.6 kilometers deep in the Antarctic Ocean lies the East Scotia Ridge (ESR) dotted with hydrothermal vents. Here, in this unique spot the world’s coldest ocean is in contact with one of the seafloor’s hottest environments. Life residing at hostile vents […]

What the hell is a “Sea Hawk” anyway?

With the […]

5 Reasons Why Great White Sharks are the Blackberry of the Seas

The following post is authored by Lindsay Gaskins as part of the Sizing Ocean Giants project. This post originally occurred on the Story of Size. 1. They are sleek yet functional. The aesthetics are impeccable, and signal just how well designed these sharks/smartphones are. Blackberry is one of the most easily-recognizable brands out there, and not for nothing. Its […]

Ocean Sunfishes: The Eeyore of the Sea

The following post is authored by Catherine Chen as part of the Sizing Ocean Giants project. This post originally occurred on the Story of Size. Sixty million times. That’s really big, but just how big? 60 million kilometers is almost half the distance from the Earth to the sun. 60 million times bigger is a baby born at […]

What is the world’s largest barrel sponge?

It is the 2.5 meter (8.2 feet) diameter giant (photo below) that was a tourist attraction for scuba divers visiting Curac?ao in the Caribbean in the early 1990s.  Unfortunately frequent touching by scuba divers likely caused lesions that lead to an infection of the sponge tissue (show as the dark spot pointed to by the arrow in the […]

Six Reasons to Supersize

The following post is authored by Caroline Schanche as part of the Sizing Ocean Giants project. This post originally occurred on the Story of Size. For those who have seen elephant seals up close and personal, there is no questioning the fact that elephant seals are not afraid to put on the pounds. This guy surely doesn’t seem […]

The weird sizes and exotic shapes of nematode worms

FACT: We study evolution in nematodes by constructing trees out of their penis size. Ok, well a “penis” in male nematodes is actually a hard copulatory spine called a genital spicule–males physically pry open the female’s vulva–but you get the idea. What better way to open a blog post about the story of size? Marine nematodes are […]

Growing Large on Jelly

The following post is authored by Caroline Schanche as part of the Sizing Ocean Giants project. This post originally occurred on the Story of Size Would you convert to a diet of cucumber? Could you do what the leatherbacks have done? None of us can really imagine surviving solely on foods such as cucumber or […]

Why isn’t the Giant Isopod larger?

What I want to discuss, and I use this word specifically as after 10 years contemplation I seem no closer to an answer, is why the Giant Isopod is, well, giant? Mosely noted in 1880 Other [animals] attain under them gigantic proportions. It is especially certain crustacea which exhibit this latter peculiarity, but not all […]

Sizing Ocean Giants: The Paper!

I am elated to announce the publication of Sizing Ocean Giants, a tome on the sizes of everything from Giant Barrel Sponges and Giant Isopods to Great Whites and Sperm Whales.  You want Giant Oarfish?  We got them!  You want Leatherback Turtles? We got them too? And we’ll throw in a Colossal Squid as a bonus. […]

Sharks and lasers, not just for evil geniuses

In midsummer 2009, under the intense Mexican sun, a whale shark, MXA-182, arrived at Holbox. He is injured. A nasty cut nearly severs his right pectoral fin. His fin eventually heals, but a hole completely through his fin still persists. The hole’s shape earns MXA-182 the nickname of Keyhole. In 2009, Keyhole is at Holbox […]

Sleuthing the Largest Snail

Earlier this year, I spent a few days tracking down the world’s largest snail. It is my own contribution to the Sizing Ocean Giants project. The Australian Trumpet shell, Syrinx araunus, is generally agreed to be the largest living snail. Shell lengths at the high end usually range around 2.5 feet (~0.75 meters). My goal had […]

The Nubbly Bits of Blue Whales

The following post is authored by Catharine Chen as part of the Sizing Ocean Giants project. This post originally occurred on the Story of Size. Adapted from Just So Stories by Rudyard Kipling. Long, long ago, there was a Blue Whale (Balaenoptera musculus) who ate everything in the ocean but a small fish. Fearing for his life, the fish […]

Integrating Research and Outreach Through Massive Ocean Animals

With 5 stunning Duke University undergraduates, I participated in an experiment, one in which science outreach and research were not separate spheres. “Time to put away the research and do some outreach.” “I don’t have time for outreach...Show More Summary

It’s Size Week At Deep-Sea News

This week at DSN we are dedicating to size. Actually, I’m dedicating it to size. Since I am the grand poobah in charge, everyone else has gone along.   Why size? First, me a superteam of students and scientists are authors of a paper coming out Tuesday at PeerJ, the culmination of the Sizing Ocean Giants […]

ROV gets caught in turbidity current, lives to tell the tale.

Imagine you are yodeling whilst snowshoeing in a majestic mountain range. All of a sudden you hear a rumble. You look up to see a white wall of snow heading towards you. You, unfortunately, are about to be engulfed by an avalanche. Now imagine you are an ROV sampling whilst exploring in majestic submarine Mendocino Canyon. You see a […]

These are a few of my favorite species: The magnificent and very large sponge Monorhaphis chuni

Within the glass sponges (Hexactinellids), so called because of scaffolds of silica spicules they form, resides a family of sponges, the Monorhaphididae. Family here is used in taxonomic sense to delineate substantially different types of organisms. Think the differences between cows and giraffes, both artiodactyls but in different families. But in the common meaning of […]
