Red sea urchin Mesocentrotus franciscanus
Sea urchins belong to a group of marine invertebrates called
echinoderms, which means spiny-skinned animals. They are related
to sea stars, sea cucumbers, and sand dollars. Like their
relatives, sea urchins do not have a brain or heart. (Aquarium of

All killer whales will remain one species — for now, according to marine mammal committee
A formal proposal to designate resident and Bigg’s killer whales as
separate species has been rejected by a committee widely recognized as
the authority in naming new marine mammal species. The proposal for new
orca species, put forth by a team of geneticists and marine mammal
biologists, was based on the distinct genetic, physical and behavioral
differences observed between resident killer whales, which eat fish, and
Bigg’s, or transient, killer whales, which eat marine mammals.

A String of Supreme Court Decisions Hits Hard at Environmental Rules
A spate of decisions over the past two years by the Supreme Court has
significantly impaired the Environmental Protection Agency’s authority
to limit pollution in the air and water, regulate the use of toxic
chemicals and reduce the greenhouse gasses that are heating the planet.
This term, the court’s conservative supermajority handed down several
rulings that chip away at the power of many federal agencies. Coral

Washington on-guard for troublesome mussel found in Idaho
Washington is upping efforts to keep an invasive freshwater mussel from
gaining a shell-hold in the state’s rivers and lakes, using tactics
ranging from DNA testing to shellfish-sniffing dogs. Quagga mussels can
cause major problems as layers of them crust over components of
hydroelectric dams and locks, or clog drinking water or irrigation
systems. Fisheries and fish ladders that allow salmon to bypass dams
could be disrupted, too. The mussels can also outcompete native species,
throw off water quality, and otherwise degrade ecosystems. Bill Lucia
reports. (Washington State Standard)
