We’re here to tell you a tail about the blue whale. 

Baleen it or not, blue whales are the largest known animal to have ever existed on Earth! Their tongues alone can weigh as much as an elephant, and their hearts are as large as a small car. In the summer and fall feeding seasons, blue whales travel to the California coast, including Monterey Bay National Marine Sanctuary, to gulp down shrimp-like krill (about four tons a day, to be exact!).

New research teases apart complex effects of naval sonar on whales

Mongabay – March 28, 2019

Whales can behave quite differently in response to sonar depending on where they live and what they’re doing, new research has found.

The pair of studies, on different species and in different oceans, adds to scientists’ understanding of how to protect whales from these sounds. Navies use sonar to detect stealthy submarines, and researchers have linked sonar training exercises to hearing loss, deadly mass strandings, and interference with whale communication.

Most strategies to temper the effects of sonar use the volume of the noise as a guide, Brandon Southall, a biologist at the University of California, Santa Cruz, said in a statement. But loudness didn’t turn out to be the best predictor of blue whales’ (Balaenoptera musculus) responses to a series of sonar blasts in research published March 4 in the Journal of Experimental Biology.

“Some whales responded when the sound was barely audible, while others seemingly ignored it and kept feeding at quite loud levels,” said Southall, the paper’s lead author.

First North Atlantic Right Whale Calf Sighting…

The first sighting of a North Atlantic right whale calf in Cape Cod Bay
this year occurred on April 7th. The calf and its mother, #1204, were
sighted by the aerial survey team at the Center for Coastal Studies
(CCS), making this the first calf sighting in the bay since 2017 as no
calves were seen in 2018. This calf was first seen near Amelia Island,
Florida on January 17th
and is the third calf out of a total of only
seven to be seen this year.

#1204 was first seen in 1982 and is at least 38 years old, she last gave
birth six years ago and is one of the most successful mothers in the
population as this is her ninth calf (#1240 and #1334 have also had nine
calves). She was sighted in Cape Cod Bay in April and May of 2018 and
was most likely pregnant with her new calf at the time of those
sightings. CCS reported in their post announcing the sighting
that out of the nine calves she’s had, this is only the second one that
#1204 has been documented with in Cape Cod Bay. We wish #1204 and her
calf the best as they swim and feed in Cape Cod Bay and hope to see the
other calves and their mothers in the bay soon!

There is currently a 10 knot speed restriction for all vessels in Cape
Cod Bay (a federal restriction on vessels over 65 feet and a state
restriction on vessels under 65 feet) along with a ban on lobster traps
until April 30th. It is also illegal to approach a North Atlantic right
whale within 1,500 feet without a federal research permit. This includes
boaters, kayakers, paddle-boarders, swimmers, light aircraft and drone
pilots. However, as CCS states, “the right whales often feed very close
to shore, offering whale watchers on land unbeatable views” of North
Atlantic right whales. Even with these protections – which are
unfortunately only seasonal and are lifted at the end of April –  these
whales still face threats from ship traffic and marine debris
in Cape Cod Bay during this time. Thankfully it is currently safer than
many areas North Atlantic right whales visit but the battle goes on to
make sure they’re truly safe.

North Atlantic right whale #2642, known as Echo, in a SAG (Surface Active Group) with multiple males in Cape Cod Bay on March 27, 2019. Sometimes right whales gather in groups like this at the surface to play but they also engage in this behavior in order to mate. Researchers at the Center for Coastal Studies observed that this one was for mating and saw that at least one male in the group successfully copulated with Echo so hopefully we’ll see her with a calf next year!
