Deanna Derosia is an illustrator and biologist born and raised in the sunny Treasure Coast of Florida.  Growing up next door to nesting sea turtles, strolling alligators, and bright pink spoonbills ignited her curiosity for the natural world, and inspired her to preserve unique habitats like Florida’s for generations to come.  She founded her business Sealacanth Studios to now help others explore our natural world, discover its oddities, and learn about their own next door critters through

the storytelling quality of art.

"Sealacanth" is a play on words for the first animal that inspired Deanna to study biology - the Coelacanth.  This living fossil was once assumed to be the "missing link" between sea and land dwellers, and in the same sense, Sealacanth Studios strives to be a much needed link between science and art.  The coelacanth also reminds us that even though extinction is a possibility, we don't know all the things nature hides from us. There's always potential to reverse the harm we've done if we still have hope.
