Monkfish Look Like They Could Bite Your Foot Off

This fish looks like it was designed by Stephen King, with its angular gaping mouth, needle-like teeth, and beady eyes. Imagine your reaction if you were enjoying a refreshing dip in the ocean then you looked down and saw that face staring up at you. I pride myself on surfing with the sharks in the bracing New England ocean, but seeing that crazy face by my feet might just leave me unhinged for a minute. These fish range throughout the North Atlantic, and as far south as Florida, so I know they’re around.

Really, though, your odds of encountering a monkfish are very low and if you did, they probably wouldn’t attack you. They usually hang out on the ocean floor, where they lie in wait, lure in prey with a filament-like “esca” that sprouts from between their eyes, and snatch up whatever unfortunate little fish happens to show interest.

As effective as this strategy seems to be, this bottom-dweller does get up near the surface every now and then – to eat birds. Researchers have recently discovered little puffins in the bellies of monkfish that were caught between 275 and 495 feet down, off the coast of Chatham, MA. Monkfish fish get around! And, I will confess, I didn’t even know we had puffins in New England.

I would really love to see some Crittercam  footage of a monkfish swimming up from the dark, cold depths and rushing a cute little unsuspecting puffin. Pow! Like a shark attack, but smaller and uglier. I’m going to be thinking about this the next time my feet are dangling off my surfboard (although researchers think the puffins were diving down 10 or 20 feet when the monkfish nabbed them). Still – as if the shark anxiety wasn’t bad enough.

Here are some other interesting monkfish facts (these and more can be found in this fact sheet from World Wildlife Fund).

  • Monkfish are also called goosefish, bellyfish, allmouth, and lawyer (that last one seems a little harsh).
  • These fish have been found almost 3,000 feet down.
  • They can eat things larger than they are, and are not very picky. Cod, lobster, and birds are all fair game.
  • Monkfish was not considered marketable in the U.S., until a government funded marketing campaign convinced people they were missing out on something that Europeans had been onto for a while.

 While monkfish have yet to show any interest in eating us, we do seem to enjoy eating them. In New England alone, commercial landings have averaged 35 million pounds a year since 1990. Hopefully this important and unique Gulf of Maine dweller will be able to withstand the  fishing pressure that is now upon them. Given the state of collapse of our cod fishery, healthier bottom dwelling fish stocks are being increasingly targeted to help sustain the fleet. This sort of action might backfire if populations of monkfish and other groundfish begin to plummet as the cod have, leaving fishermen with less and less. Worse, there are pressures on groundfish other than fishing, like warming seas and ocean acidification, which make it important that we set some habitat aside for our ocean ecosystems to adapt and build resiliency to our changing environment.

As odd looking and voracious as monkfish are, they are an important part of our New England ocean ecosystem. I hope that our fisheries managers and researches keep tabs on monkfish populations so we don’t imperil this true ocean oddity. Especially since I haven’t seen that Crittercam footage yet.

Sheepshead Fish Teeth

Sheepshead Fish are a True Ocean Oddity

April is National Humor Month, so here’s some evidence that nature can tell a good joke. Meet the sheepshead fish. I can tell you all about where it lives, how big it gets, all the usual statistics. But wouldn’t you rather know about those teeth?

Sheepshead fish eat all kinds of things – from soft-bodied marine worms to clams and barnacles – so they need teeth that can accommodate this dietary range. Teeth like ours, as it turns out (although I’m not sure we could crunch up a clam shell). They also have a bonus feature we lack –  extra rows behind the front teeth.

Crazy teeth aside, they are a pretty attractive looking fish, with vertical black and silver stripes that have earned them the nickname “convict fish.”

These odd little fish are actually quite common – ranging from Cape Cod to Florida. In spite of the impressive looking chompers, they only get to be about 30 inches long, and 15 pounds. I hear they are tasty and popular with recreational fishermen, but I’m not sure I could get past those teeth.

 

Ocean Oddity: Sea Cucumber Feasting on Plankton Buffet

Categories: Ocean Oddities

Brian Skerry snapped this feeding sea cucumber in New England’s chilly waters, off the coast of Maine. To learn more about this real-life sci-fi creature, we spoke to Dr. Rick Hochberg of the University of Massachusetts at Lowell, who filled us in on the details. Based on this extreme close-up of the animal’s mouth and tentacles, Dr. Hochberg guesses that this is a Psolus fabricii, commonly called the scarlet psolus.

“The color of this subtidal sea cucumber is generally scarlet to orange (at least around the oral tentacles), but the body may be somewhat brownish. They can grow to about 8 inches long and are often found associated with hard substrata (rocks, reefs) where they spend their time feeding on suspended food in the water column (e.g., plankton). The picture shows the animal bending one of its ten oral tentacles toward its mouth to clean off the microscopic food that is caught by the extremely numerous and fine, mucus-coated tentacles.” Yum!

Did you know that June is National Zoo and Aquarium month? If you want to see creatures like this marvelous sea cucumber close up, now is a great time to pay a visit to your local aquarium. Here in New England, we have one of the country’s finest – the New England Aquarium, where Brian Skerry is an explorer-in-residence. Support these important institutions with a visit to the NEAq, or your local aquarium this month.

Ocean Oddity: Right Whale Baleen

Categories: Ocean Oddities

Alien species? Even better: this is an amazing close up shot of the baleen of a right whale.

The right whale opens its mouth while it feeds, using its baleen to skim out the nutrient rich zooplankton it needs to maintain its super thick blubber layer. Right whales feed near the surface, making it possible for Brian to capture this fantastic image.
