Megavertebrate Week


The writers at Deep Sea News are big fans of all things invertebrate. We bend over backwards trying to convince people that deep-sea worms, isopods, anemones, and squid are the coolest animals anywhere on Earth. We stick up our noses at charismatic megafauna like sea turtles and whales, thinking “What could possibly be so interesting about air breathing animals with bilateral symmetry?”

We recognize that “normal people” like the vertebrates, especially the marine megavertebrates. People identify with seals, penguins, and sea lions in ways that invertebrate biologists will never understand or aspire to. No one loves a lobster. We rescue them from the boiling pot as children, and hide them from our parents in the bathtub (this is true). We love to catch them and eat them with butter. We love the efficiency in their design, and the vagueries of their life history, but we’ll never feel the same emotion for a lobster that a dolphin trainer feels for their animal. No way. Invertebrate biologists just don’t go there.

Don’t get me wrong. I believe there is something very special about the megavertebrates. They make good habitat for parasites. Oops. Sorry. I mean,… they have a connection to people. This hit me once when I was preparing a testimony for the Ocean Commission in Hawaii. I sat on a porch the night before writing of the whales of yore, enraptured by their treacherous demise, when an upwelling of emotion came over me suddenly. I was petrified by a thought. If we hunted these whales nearly to extinction, I wondered, what else are we capable of? Are all seven species of sea turtles endangered because of the human race? Is this a sign? A portent of doom? Could we be next?

Megavertebrates tug our heartstrings because these animals are the most like us. We recognize ourselves in their expressions. We can even picture ourselves in their skin– diving deeply like whales, resting on the beach like seals, swimming playfully like dolphins, lying on our backs wrapped in kelp like otters. Part of us longs to be there with them, away from the worries of the modern world.

So we follow them now, into the deep blue sea. Welcome to Megavertebrate Week. Over the course of the next few days we’ll explore deep diving behavior in whales, turtles, and elephant seals, tune in to some important conservation happenings, tap into new research, and learn a few things along the way. Enjoy the postings we offer this week, please. Several first-time writers will be contributing. Comment often if you can. Thanks for reading.

  1. megavertebrate or charasmatic megafauna… whichever sobriquet you prefer, this cnidarian-loving reader couldn’t agree more that the big marine stuff is still very cool… it’s a face thing… and love the pie chart for perspective… i thought another diagram (link below) might also add some context since it’s always worth reminding non-eukaryote types how small a twig on the bush of life the “animal pie” (including the big stuff) occupies… looking forward to the megaverts…

  2. Thanks, Rick. Good to have you with us.
    Love your blog and image map. Farewell Don Ho.

  3. I’m currently reading the Rifters scifi series. It’s about a bunch of deep sea divers in THE FUTURE. :)

    Oooh, there’s something I’d like to share with you. It’s from one of my favorite web comics. This particular strip features the most cunning of all sea critters:

  4. I am working on my Master’s in Conservation Biology, and naturally, I’m attracted to any articles that feature turtles, terrapins and tortoises. So yea, I’ll drop by as often as I possibly can :)

  5. I am stoked about Megavertebrate week. Yes Peter, the more you could put about sharks, the more hooked I’ll be. I love all the big guys!
