More than great whites: East Coast waters host dozens of shark species

Sure, the great whites get all the attention, but there are lots of other sharks in the sea you are swimming in this summer.

The coastal waters off the Eastern U.S. host dozens of shark species, from sand to dusty, and some can be ten feet long. And for the ninth year, National Oceanic and Atmospheric Administration scientists this spring caught and tagged sharks as they congregated in the warm waters between Florida and Delaware. As waters warmed, some of the species moved North - including into New England.

The U.S. only began regulating shark fisheries in 1993 - today they watch over 39 species - and there are great unknowns about the sharp-toothed group, from diet to longevity. The survey scientists record the sex and location of each animal. Dead sharks are dissected at sea to get parasite, DNA and blood samples and researchers collect other data to determine shark age, growth and food habits. Ultimately, researchers hope to get a better handle on shark populations.

The researchers, from the Northeast Fisheries Science Center lab in Narragansett, RI caught 1,675 sharks from 19 different species this year - an all time record. Most were sandbar, tiger and dusky sharks although some Atlantic sharpnose – a four foot long shark that eats shrimp and small fish - and one great white were also caught.

Don't worry - It’s rare for any shark species – even great whites for all their Jaws lore – to attack humans. But next time you go swimming, be aware a giant fish may be very close by.

  1. How dunderheaded is it for a blog called Green Blog to have its single photo be one of a dead shark, and one that looks like it was fished to death?

    Wouldn't a photo of live sharks in the sea - or better yet, a series showing what sharks actually live in East Coast waters - be more appropriate?

    Sloppy, lazy photo editing. Boston.com can be better than this.

  1. That picture is disgusting-- hey, let's celebrate and party while killing our fellow species!!! Most shark species are in trouble all over the world, and the loss of the apex predator in the ocean is already having devastating effects on the ecological balance.

    I wonder if Mr. Spielberg has contributed mightily to Oceana and other worthy organizations hoping to save our ocean waters, for all the shark-killing hysteria he has induced over the years, at a mighty profit.

  1. There's a shark in that picture?

  1. thought this was illegal?
    this bull-spit is infuriating, killing for sport is outrageous. Shame on you.

  1. We have swum with sharks many times, on about every third or fourth dive. They go on about their business, and we go on about ours. We would never think of catching and killing one, as shown in Ms. Daley's photo, any more than we would hunt other reef fish. If Ms. Daley cannot report from similar experience, she should leave the topic to someone else who can.

  1. Animal Rights wackos oppose fishing.

  1. Why would you use a photo from a shark tournament in this article? Shark tournaments are extremely wasteful and should be prohibited. Shark populations throughout the world are overfished and glorifying killing these vulnerable top predators is shameful.

  1. What a bunch of nutballs. "Sharks and other reef fish". Yes, there are sharks- and those on the East Coast are not imperiled.

  1. While I have no problem with fishing for sharks, when done within the regulations, it does seem odd that the article is on a shark tagging survey, and the picture is from a fishing tournament. Wouldn't a picture showing how a shark is tagged been more informative and appropriate? I'm fairly certain that the researchers take pictures while on their survey.

  1. why would anyone kill a fish if they weren't going to eat it?

    seems like an insane waste of fossil fuels to get there, other fish to catch it, and then the fossil fuel to come back just for the excitement of killing something that is minding it's own business.
    isn't there a recession or something?

    least you could do is eat it.

    then again, americans are so fat that maybe they should start burning energy to kill things rather than wait in a 2 mile traffic jam to eat a fast food hamburger.

  1. No one is opposing fishing here, but these tournaments target the big old female fish that are critical for a species survival. Not to mention the bycatch rate of sharks is tremendous and they just slowly suffocate when they become trapped in gillnets or tossed back in the water without any fins. Sharks are disappearing all over the world because we're fishing them out. Plain and simple and we need to stop this.

    They take a long time to be sexually mature (some over 30 years!) and only have one or two babies at a time. So if we go about killing them for sport we're not going to have sharks around for much longer. I love fishing, but when tournaments target fishes like sharks there won't be any around for my kids to catch when they grow up. A much better plan is to make these tournaments tag and release. This way by affixing a tag we can learn more about sharks than we would by just killing them. Slaughtering sharks for sport is just inhumane and un-American.
