Bright yellow snail species discovered in Florida Keys gets named after delicious cocktail

CHICAGO — A newly found vivid lemon-hued snail species within the Florida Keys has earned its title from the area’s well-known Margarita cocktail. The marine creature’s vibrant citrus shade may be a defensive mechanism towards predators, in accordance with researchers.

The Florida Keys, a sequence of tropical islands, boasts the one residing coral barrier reef within the continental United States and is house to quite a few distinctive species. Enter the Margarita snail.

These eye-catching yellow creatures, together with their lime-green counterpart from Belize, are distantly associated to the frequent land snails, recognized for his or her backyard slime trails. Distinctive of their habitat selections, these worm snails sometimes calm down early in life, anchoring themselves to a spot, by no means to maneuver once more.

“I discover them significantly cool as a result of they’re associated to common free-living snails, however when the juveniles discover a appropriate spot to reside, they hunker down, cement their shell to the substrate, and by no means transfer once more,” explains the research’s lead writer, Dr. Rüdiger Bieler, in a media release. “Their shell continues to develop as an irregular tube across the snail’s physique, and the animal hunts by laying out a mucus net to entice plankton and bits of detritus.”

Having devoted over 40 years to learning Western Atlantic invertebrates, Dr. Bieler, additionally the curator of invertebrates at Chicago’s Subject Museum, expressed shock at solely lately encountering these snails, highlighting their inconspicuous nature. He recognized these species as family members to the invasive “Spider-Man” snail found off the Florida Keys in 2017.

“Many snails are polychromatic – throughout the similar species, you get completely different colours. In a single inhabitants, even a single little cluster, one may be orange, one may be grey,” Dr. Bieler notes. “I feel they do it to confuse fish and never give them a transparent goal, and a few have warning coloration.”

The researchers initially believed the lime-green and lemon-yellow snails to be of the identical species. Nonetheless, DNA sequencing revealed stark variations.

Consequently, the workforce launched a brand new genus for these snails, named Cayo (Spanish for “small, low island”). The yellow snail turned Cayo margarita, impressed by Jimmy Buffet’s “Margaritaville.” The lime snail was christened Cayo galbinus, translating to “greenish-yellow.”

Notably, these Cayo snails share traits with one other worm snail genus, Thylacodes. Regardless of being solely distantly associated, each have vibrantly coloured heads rising from their shells.

“Our thought is it is a warning shade. They’ve some nasty metabolites of their mucus. That additionally would possibly assist clarify why they’re in a position to have uncovered heads – on the reef, all people is out to eat you, and should you don’t have any defensive mechanism, you’ll be overgrown by the corals and sea anemones and all of the stuff round you,” Dr. Bieler hypothesizes. “It looks like the mucus would possibly assist deter the neighbors from getting too shut.”

With global water temperatures rising and coral reefs dying, these snails might quickly multiply.

“It’s one other indication that proper below our noses, we have now undescribed species. That is in snorkeling depth in a closely touristed space, and we’re nonetheless discovering new issues throughout us,” concludes Dr. Bieler.

The research is revealed within the journal PeerJ.
