I am a returning student intrigued by larval development, extreme habitats, inverts (especially cephalopods and crustaceans), marine conservation and science communication. Where these interests will take me, I don't know exactly but with my family's excellent support it will be an interesting journey!
Ok. I said for each of the Ocean in the Classroom projects fully funded I would put up a post about one invert from the deck of cards I have been working on, along with a sneak peak at a card. So, since the Making Waves, Oceans and Landforms got fully funded, and in honor of Nautilus Night I bring you the Cephalopod of Diamonds - The Chambered Nautilus.Classification for the Chambered NautilusKingdomAnimaliaPhylumMolluscaClassCephalopodaOrderNautilidaFamilyNautilidaeGenusNautilusSpeciesN. belaue........

We've got two new Ocean Inspired Donors Choose projects that have been funded in the Oceans in the Classroom Challenge! The first one that was funded on Thursday was the awesome Invertebrates in my Tank project that will provide lots of kids with the opportunity to explore one of our favorite subjects: marine inverts! The Inverts in my Tank card is the 6 of Spades — The Slipper Snail, Crepidula fornicata.Classification for the Atlantic Slippersnail KingdomAnimalia PhylumMollusca ClassBivalv........ Read more »

After posting to the Scallop of Hearts to TO95%, I remembered it’s Blog Action Day for the cause of climate change awareness.
One of the major concerns with climate change relates to habitat changes for the plants and animals. Will aspen survive anywhere in the United States? What trees will be able to survive in [...]... Read more »

Time to celebrate the funding of Mrs. M.'s project, Coral Reef Flip Books, part of the Ocean Bloggers Oceans in the Classroom Initiative. Yesterday I asked for input on which card to feature, and the results are in: with 33.33% of the "vote" the Scallop of Hearts gets the next preview here. I should note that the picture on this card is likely to change before the final version, when we hopefully will get an image of a live animal without too many epibionts (organisms that live on the surface of........

It's been a bit quieter around here than Kevin and I prefer, but now the finals are all done and I can finally say "I can has cheezburger wit dat?"Seriously though, in the next month or so there will be some changes in this space... in the mean time:Did you know there are 198 invertebrates listed under the Endangered Species Act? Yep, inverts make up 34% of the 575 animals protected under ESA. But is this good or bad that inverts are underrepresented here?? Care to guess how many of those 198 a........ Read more »

Roger Hanlon, from the Woods Hole Marine Biological Laboratory, came out to UCONN's Avery Point campus to present for our Friday seminar series. His presentation was a good overview of his lab's work on cephalopod camouflage behavior over the past decades, with the majority of the discussion on the work they have done recently with the cuttlefish Sepia officinalis. So I hope you will bear with me while I gush on a bit about my favorite group of animals and their amazing adaptations, which allow ........ Read more »

Yummm… necrophagous larvae, or maggots, of the Blue Blow-Fly,Cynomyopsis cadaverina (Robineau-Desvoidy). The larvae of many species of fly feed on dead tissue. This is highly useful as an ecosystem service as they very effectively clean up any carrion that is missed or left over from any larger scavengers.
Some species maggots feed only on necrotic [...]... Read more »

Differential Grasshopper by Eclectic Echoes ©2008 BY-NCDid you know that the Differential Grasshopper (Melanoplus differentialis) prefers wilted or damaged sunflowers? This one is seen on a sunflower that was damaged in recent winds we had here (tail end of Hanna). I wondered why it was that the grasshoppers (2 found) and the evidence of grasshopper activity – chewed leaves and copious amounts of feces – was all on the damaged sunflowers and not on the still healthy plants.In 1984, A.

Cyamus ovalis Photo: Vicky Rowntree, University of UtahIn an earlier post, I joked (well half joked) about the need to save the whale lice, even if you don't care about the right whales. I thought today I would expand on the brief comment about the lice and their special relationship with whale and how they can actually tell us about the populations of right whales and their evolution.
