is a vertical fault in a cliff that has widened after exposure to strong waves - creating water pressure that can shoot up through the hole.
Fearnbach called positioning directions at a rapid pace that would rival that of a veteran auctioneer, and Durban piloted the hexacopter several feet above the blowhole
. Some of the blow landed on a sterilized petri dish on top of the drone.
are dependent on weather: air temperature and pressure interact to create the stunning effects when air travels from higher to lower density.
Unlike other baleen whales, the two blowholes
on right whales are widely separated, causing their spouts to be seen as two distinct sprays.
They breathe air through blowholes
that lead to their lungs (unlike fish that breathe using gills).
As a result whales now use blowholes
starfish still hide in sandy rock pools and koalas have strong arms and flattened faces.
3.5 feet long is the size of a remote-controlled helicopter used to collect snot from whales' blowholes
. The mucus samples will help scientists learn about bacteria living inside the animals.
. Blowholing issues are often due to pinholes or other irregularities in the PTH plating, and can be very difficult to address.
All types of discontinuities in the walls of the casts, including the blowholes
, conduct to the diminishing of the mechanical properties.
The whales also have an unusual hunting technique where they make "nets" of bubbles with the air they expel from their blowholes
. First the whales make a deep dive and then they swim to the surface in a spiral pattern while they release a steady stream of bubbles.
Numerous parties report significant increases in blowholes
. These increases vary from a few percentage points to double-digit hikes.
While we don't have blowholes
, we do share a number of traits with humpback whales: we are warm blooded, breathe air, give birth to and nurse' live young.
