A team of researchers led by California State University’s Professor Patrick Krug has discovered three cryptic new species of sea slugs.  The three new species were previously considered to be the same as a species known as Placida cremoniana from the Mediterranean.  One of them is named after former U.S. President Barack Obama, to honor his dramatic expansion of the Papahānaumokuākea Marine National Monument in Hawaii, as well as his administration’s commitment to fighting global climate change.  The two other species are named to honor diver-photographers.  Photographic records and literature reports suggest that additional species may occur in the Indian Ocean, tropical Australia, andRead More

A completely new group of sponges has been discovered, which scientists believe could be a key indicator species in measuring future mining impact in a region targeted for deep-sea mining of polymetallic (metal-rich) nodules. They are likely to be the most abundant nodule-dwelling animal in the area.  See also ecosystem targeted for deep sea mining.

“You can’t just accept discovering science as ‘enough,’ says California Academy of Sciences Curator of Invertebrate Zoology and Geology Terry Gosliner. “We have an obligation to explain its relevance. We need to find more ways to transfer scientific findings to the public so that we can positively impact public policy and conservation management – especially now, when the natural world is changing so rapidly.”

A diving expedition off Easter Island, 60–150 meters beneath the surface (the “twilight zone”), reveal new species of fish and invertebrates.  In collaboration with SUBELAB Pontificia Universidad Católica de Chile, a scientific team from the California Academy of Sciences became the first divers to study mesophotic ecosystems off Rapa Nui.  An orange colored sea biscuit, and four fish collected are almost certainly new species.  California Academy of Sciences Ichthyology Curator Luis Rocha plans to give the fish all Rapa Nui names in honor of the local culture.

Researchers studying a colorful group of sea slugs (also called nudibranchs) found along the California coast have named a new species in honor of Gary McDonald, a long-time staff member at UCSC’s Long Marine Laboratory.   The striking orange-red new species is about an inch long, found along the coast from Baja California to Sonoma County.   Based on the examination of over 600 images of specimens of Limacia available on Flickr and iNaturalist it appears that L. mcdonaldi sp. nov. has been common in the Monterey and San Francisco bay areas from 2014 through 2016.

A huge invertebrate diversity is hidden on the forest floor in areas of the Araucaria moist forest, Brazil. Land flatworms constitute a numerous group among these invertebrates occurring in the Neotropical region. Flatworms are considered to be top predators within the soil ecosystem, preying on other invertebrates.

The Western Australian Museum provided a chance of a lifetime: for anyone to stamp a personal imprint on biological history by naming a species. The museum’s Dr Nerida Wilson discovered this new species of nudibranch while diving off the coast of north-west Western Australia.   Thousands of people entered the competition, and at the end of an exhaustive judging process the species name chosen for this gorgeous nudribranch is … Moridilla fifo The name honours the fly-in fly-out mine workers of Western Australia, with their blue and orange coats.

Scientists have rediscovered a snail species not seen for over a hundred years after spotting a picture of the species on a citizen science website inaturalist.com.   Though the snail is common on Hon Cau Island, it is so rarely visited due to national park restrictions and its distance from Con Son Island off the southeast coast of Vietnam, that no researcher had ever traveled there to document the local flora and fauna.  Fortunately, citizen scientists are documenting species and habitat in the most far reaching locales.

Extremophile Worms Found in Colorado Cave

Extremophile Worms Found in Colorado Cave

Invertebrates, New Species May 11, 2016 at 8:47 am

As a research associate with the Denver Museum of Nature & Science’s zoology department, Dave Steinmann estimates he finds around 10 new species per year in Colorado.  But it took more than 1,000 hours of multiple independent lab tests, study for these “blood-red worms” to become official this year.  The hydrogen sulfide gas that fills the cave required a rescue team to wait outside while Steinmann explored. His discovery is significant because these “extremophile” worms — which are red, thin as pencil-lead and an inch long — show how life might have developed in other inhospitable environments like Mars orRead More
