BABY CORALS AND FISH SMELL THEIR WAY TO THE BEST HOME
New research suggests that these creatures, baby fish and coral larvae, smell their way to neighborhoods where the living is good. Scents emitted by certain species of adult corals draw fish and coral larvae to healthy reefs, while the noxious odor of out-of-control seaweed drives them away from damaged ecosystems.
Young fish and coral larvae are cast out into the open ocean after they are born, to swim or float away on currents to new ecosystems. Some eventually return to their spawning grounds—especially if their hometown happens to be in a protected marine habitat—while others settle elsewhere. But these days, many fish and coral larvae are finding themselves with limited options: More and more unprotected reefs have been taken over by seaweed, which smothers coral, disrupts food webs, and perhaps even poisons potential settlers.
Both fish and coral larvae have been observed navigating away from those degraded reefs and toward healthy ecosystems. A baby coral is “a bag of snot with some cilia around it. How could it go one place and not another?”…… continue reading

Boston University’s Marine Science Association is hosting the annual Lobster Ball sunset harbor cruise on the last day of classes! There will be pizza, dancing, and beautiful views of the city.
Quick ticket link: http://www.eventbrite.com/e/bu-marine-science-associations-lobster-ball-tickets-11421948355?aff=es2&rank=1&sid=1bc8104fcc8411e39e261231390f9522
Dress: Formal attire including an article of red clothing.
Everyone is invited, so invite your friends who may be interested!
Transportation: From BU, take the Green Line Inbound to Park Street. Then switch to the Red Line towards Ashmont or Braintree, get off at South Station. Switch to the SL1 (silver line bus towards Logan Airport), take 2 stops until the World Trade Center Stop. Walk northeast one block to the World Trade Center pier. This will take 40+ minutes, so plan accordingly. Taking a taxi is another option. The event ends at 10pm, so there will be plenty of time to take the T back to BU.
Food and drink: Pizza will be served and a cash bar will be available.

Peace & Fish Love,
Although we don’t have a normal meeting scheduled for this week, we did sign us up for an
Interviewing for Success workshop at the Center for Career Development. The workshop is from 6-7 pm Thursday, April 17th in Room 101 at 100 Bay State Road. This workshop is relevant to anyone so feel free to bring your friends!
See you tomorrow,
Garden Eels | Heterocongrinae
“Tightening its very muscular body to make itself rigid, a garden eel drives its pointy tail deep into the sandy sea floor. The skin in the tail contains a hard substance, so it isn’t hurt. Once the eel is deep enough, it wiggles its dorsal fin, pushing sand out of the hole. Slime from their skin cements the walls of their burrows, preventing cave-ins. Like many other reef animals, garden eels escape from predators by diving tail-first into reef-bottom burrows. When they’re not hiding, these fish sway in the current like blades of seagrass. Each eel lives in a single burrow, which they rarely ever leave.” -
