New species of sea slug discovered by UCSB marine scientist

Sometimes, treasures can be found in your own backyard –– especially if you know what to look for. This is what happened to Jeff Goddard, project scientist with the Marine Science Institute at UC Santa Barbara.

Goddard was working in the tide pools at Carpinteria Reef, in Carpinteria State Park, Calif., when he found a new species of nudibranch –– a group of sea slugs noted for their bright colors and delicate forms.

Recognizing it as new, Goddard carefully documented the living specimen before preserving it and sending it off to Terrence M. Gosliner, an authority on the taxonomy of sea slugs at the California Academy of Sciences in San Francisco. Goddard kept the slug in his lab for a few days, until it laid an egg mass, and was also able to observe its early development and hatching larvae.

Gosliner named the new sea slug after Goddard when he described it –– and one other newly discovered species of California nudibranch –– in the Sept. 15 online edition of the Proceedings of the California Academy of Sciences.

"The shallow-water nudibranch fauna of Southern California especially is well known, so it was pretty exciting to find a new species right under our noses here in Santa Barbara County," said Goddard. "Only one specimen was found, so now we need to find out where more are hiding, what they feed on, and whom they interact with."

Goddard said that he was honored that Gosliner chose to name the new species after him. The scientific name is Flabellina goddardi, and it measures about 30 millimeters long when stretched out and crawling. The genus Flabellina also includes the well-known "Spanish shawl" nudibranch, Flabellina iodinea. Goddardi is now the fifth species of Flabellina known from California.

In the scientific article, Goslinger writes: "Flabellina goddardi is named for friend and colleague Jeff Goddard who found the only specimen of this distinctive species. Jeff is the consummate naturalist with superb powers of observation."

For the scientific record, Goddard describes the new species as "characterized externally by its smooth rhinophores; long tail and cephalic tentacles; pointed foot corners; red and orange tipped cerata; and lack of pigmentation on the head, body and head tentacles."

Goddard discovered the sea slug in 2008. As with many taxonomic discoveries, the finding often takes a couple of years for documentation, comparison with known species, and publication. Meanwhile Goddard and his colleagues will continue searching for more specimens of the newly described species.

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
