Marine Mammal Spotlight - Toothed Cetaceans

There are at least 61 species of toothed whales dolphins and porpoises, ranging from the largest 16-20m sperm whale to the smallest 1-1.2m Hector dolphin.

Hectors

Hector's dolphins

Kaikoura is unique for both the sperm whale and the hector dolphin, both of which could be observed almost daily off the coastline. A total of around 9 different toothed whales and dolphins have been positively identified on more than one occasion off the Kaikoura coast which include: dusky dolphins, bottlenose dolphins, southern right whale dolphins, pilot whales, killer whales and the beaked whales, all being beautiful creatures to see in the wild.

Odontoceti’s use their teeth to seize prey such as fish or squid, which is then generally swallowed whole.  In order to locate and catch their food, the toothed whales and dolphins, like bats have developed a sonar or echolocation system, in which sounds are emitted from their heads and reflect off solid objects.  The returning echo is interpreted by the whales and dolphins and enables them to determine the size, composition, distance and direction of the object they have focused on.  The sperm whales echolocation sounds like the rhythmic clicking sounds of a clock – such as this example.

The sperm whales echolocation is what we listen out for when using our captains use our purpose built hydrophones, listening out for the rhythmic clicking sound (like the ticking of a clock) as they are in search mode of their prey or navigating their way.

In addition to their echolocation most toothed whales and dolphins have developed the ability to communicate by using clicks, whistles, squeaks, squeals and some such as the orca have even developed dialects which differ from pod to pod.

Many toothed whales and dolphins utilize these communication skills to help catch their prey and form social groups to hunt cooperatively. 

One way you can tell toothed whales & dolphins from baleen whales if by their blowholes with toothed whales and dolphins having one blowhole and baleen whales having two. Another difference being that baleen whales have a small throat and large tongue whereas the toothed whales & dolphins have a large throat and small tongue.

***WHALE WATCH KAIKOURA UPDATE***

Over the last week we have had around 3 to 4 sperm whales feeding close inshore which has made for some fantastic sightings. There has also been a humpback whale visiting Kaikōura over the last couple of weeks which has been making itself known on our tours also much to our crew and customers delight. Dolphins, NZ fur seals and marine birds have also regular viewings on our tours.

For guests who are planning on joining us over the next week please note NZTA have issued a notice to all travellers that State Highway 1 Coastal Route south from Kaikōura to Christchurch is closed to all traffic from 8pm on Sunday 26 March to 7am on Tuesday 4 April. This is to allow remedial work to take place and to make the coastal route more resilient during times of unfavourable weather. Please use Inland Route 70 which is open 24/7 during this time, please also allow extra time in your travel plans when using this alternative route.

Progress is being made on the repair of the Kaikōura Marina and we continue to switch between using a berth and our modified trailer unit for launching our vessel Tohorā, when and where possible we are also making use of the public jetty that we have modified, (this is a first for us but when presented with challenges we have embraced them post-earthquake and used our ingenuity) this is due to tidal restrictions and repair work as a result of the coastline lifting by +1.0m. It is anticipated that the Kaikōura Marina will be fully operational by the middle of this year.

Currently our available tour times are based around the tide times on the day and may differ from the tour times originally advertised, please bear with us as we continue to work toward being fully operational again. For an update on the tour times available please contact our Customer Service team directly either by email on res@whalewatch.co.nz or phone +64 3 319 6767 or free phone 0800 655 121 (within NZ) and they will be able to help you with your inquiry.  Please note we are operating at a reduced capacity in the interim with up to 3 tours available per day, please contact our team prior to arriving in Kaikōura to secure a space on one of our tours and to save disappointment.
