Incredible Knysna Marine Sightings

Marine Life Sightings on the Knysna Lagoon & Indian Ocean

The waters of the Knysna Lagoon and the iconic Knysna Heads are home to remarkable marine life. On our Scenic, Marine and Sunset cruises, guests regularly encounter playful dolphins, curious seals, abundant birdlife, and seasonal whale sightings along the Garden Route coastline.

Bottlenose dolphins are frequently seen near the Knysna Heads and in open waters beyond the channel. Watching them swim alongside the vessel is a highlight of any ocean sailing experience.

Cape fur seals are often spotted basking on the rocks or playfully navigating the currents near the Heads.

During whale season (typically June–November), Southern Right and Humpback whales may be seen offshore, breaching and tail-slapping in spectacular displays

The Knysna Lagoon is rich in bird species, including African fish eagles, cormorants, terns, herons, and black oyster catchers — making it a paradise for bird enthusiasts.

Ocean Sightings

HUMPBACK & SOUTHERN RIGHT WHALES

These gentle giants migrate along the coast, with peak viewing season from June to November.  Ocean Sailing Catamaran Boat Tours and cruises are popular for viewing these marine mammals in season.

SUNFISH

Sunfish are so called because of their habit of drifting at the surface as if basking in the sun.   Ocean Sailing Charters, often encounter these majestic ocean creatures while on out on their catamaran cruises.

DOLPHINS

Knysna is a premium dolphin watching destination, offering all year round sightings of Bottlenose, Humpback and Indo-Pacific Humpback dolphins all along its coastline.  Our boat-based Scenic Day, Marine Adventure, and Sunset tours, departing from Thesen Island, provide regular close encounters, often spotting these dolphins alongside seals, sharks, and whales.

THE KNYSNA SEAHORSE

It is the only seahorse that is earmarked as endangered.  They are endemic to the Knysna, Keurbooms and Swartvlei estuaries on the south coast of South Africa. Seahorses swim upright and rely on their curled tails to cling to reeds and seagrass.  Sightings are rare, however, you might just find yourself lucky to see these elusive lagoon creatures in their natural habitat.  

TURTLES

Green and Loggerhead Turtles are occasionally sighted in the Knysna Lagoon during stranding season (February to July), while out on a cruise with Ocean Sailing Charters.  Stranded hatchlings are often found along the beaches of the Garden Route between March and October, as cooler weather conditions make survival more challenging.

MAKO SHARK

Arguably the fastest fish in the sea the maco shark can attain bursts of speed of up to 45 km/h and are often seen performing spectacular leaps from the water – this characteristic behaviour is not fully understood.

RAGGED TOOTH SHARKS

Ragged-tooth sharks have a plump, dark-brown to olive-grey body and a pale underbelly – the numerous dark spots fading with age.

ORCA or KILLER WHALE

Orcas belong to the dolphin family and occur occasionally throughout the year.

HAMMERHEAD SHARK

Unlike most sharks, hammerheads usually swim in schools. We often see them from the yacht while out in the ocean.

GREAT WHITE SHARKS

The great white shark is known for its size, with mature individuals growing up to 6.4 m in length and 3,324 kg in weight. They are also spotted more regularly during the winter months.

BRYDES WHALE

Brydes Whales are permanent residents and can be seen in our waters year round.

CAPE FUR SEAL

A large colony of Cape Fur Seals lives on the Robberg Peninsula, they are often spotted in the lagoon and can be very entertaining to watch.

AFRICAN PENGUIN

Also called Jackass penguins, they make donkey like braying sounds to communicate.

CAPE COMMORANT

Is an endangered seabird that is endemic to South Africa. Famous for its glossy green-black plumage, distinct turquoise eyes, and bright orange gular pouch, it is a highly gregarious species known to forage in massive, offshore flocks

CAPE KELP GULL

Cape Kelp Gulls can be seen picking up shellfish and repeatedly flying up several meters and dropping them onto the rocks below in order to break them open.

BLACK OYSTER CATCHER

South Africa’s second most endangered coastal bird.

Land Sightings

BUSHBUCK
A common occurrence throughout the Garden Route, these beautiful creatures are quite shy and scatter quickly when disturbed.
DASSIE
Dassies can often be seen running around on the rocks at Robberg Nature Reserve.
VERVET MONKEY
In addition to very interesting behavioural research on natural populations, vervet monkeys serve as a nonhuman primate model for understanding genetic and social behaviours of humans. They have been noted for having human-like characteristics, such as hypertension, anxiety, and social and dependent alcohol use.
GRYSBOK
The Cape or southern grysbok is a small antelope that is endemic to the Western Cape region of South Africa.
MONGOOSE
Some species can learn simple tricks. They can be semi-domesticated and are kept as pets to control vermin. However, they can be more destructive than desired; when imported into the West Indies to kill rats, they destroyed most of the small, ground-based fauna.
BLUE DUIKER
Blue duikers stand around 35 cm tall at the shoulder and weigh 4 kg. They are among the smallest species in the antelope family.
LEOPARD
The Elusive Robberg Leopard has been spotted a few times and spoor is regularly seen to verify his existence.
CARACAL
Today, many people consider the caracal an “exotic” pet, although they do not behave domestically in captivity. Despite its wild attitude, attempts have been made to crossbreed caracals with domestic cats to produce a “domestic” caracal.
GENET
Genets are slender cat-like animals with a long body, a long ringed tail, large ears, a pointed muzzle and partly retractile claws. Their fur is spotted, but melanistic genets have also been recorded.
