Sperm Whale - Kaikoura New Zealand
 |
|
| [Note Guidelines] Photographer's Note |
Today's activities comprised of a Whale Watch trip out from South Beach Kaikoura. We saw two Sperm Whales. Sea conditions were okay but for a large rolling swell of approximately 1.5mtrs. This made photography challenging and this post is not as sharp and focused as I would wish. Luckily my husband and I don't suffer from sea sickness, but there were plenty on the boat that did.
SPERM WHALES
The great Sperm Whale is the largest of the toothed whales. Although the Sperm whale is easily identified it rarely shows much of its body above the water. This whale has a very distinctive huge squarish head occupying at least one-third of its body and projecting, often up to 1.5m (5ft), well beyond its lower jaw. The large head contains a cavity called the spermaceti organ which is a mass of web-like tubes filled with spermaceti oil (whaling) Scientists believe this organ is used in maintaining buoyancy and enable the whales to dive to such profound depths. They also believe this substance is involved in producing the powerful acoustic clicks the whales use for echo-location and to stun their prey.
The Sperm whale has a robust body with corrugations in the skin giving it a shrivelled prune-like appearance. The skin is dark grey or brownish grey. It is paler at the front of the head and on the belly, with white fringes to the mouth particularly in the corners.
The Sperm whale has one blowhole which gives a bushy blow projected forwards at a sharp angle to the left. There are two openings to the nasal passage divided by an external central septum but these are internal. The whale has no dorsal fin but it has a distinct triangular or rounded hump two-thirds along the body followed by a spinal ridge to broad triangular and deeply notched tail flukes. A thick 'keel' not seen in many whales runs along the underside of the tail stock.
Food: Squid, octopus, fish - [N.Hemis.] rock fish, skate, angler fish, lumpsucker, cod, brown ragfish, [S.Hemis.] cusk eel, rough fish, groper, king-fish, eels.

Pam, I've never seen even a tail of one of them...
Nice moment, nice action. Keep on bringing them whenever possible.
Wow... this is a new whale photo for me. We see the humpbacks on their migration path here in California. Thanks for sharing your vacation with us :-) Very nicely done!
