Lagoon dives

Diving has been very good lately. When we go outside the bay, we almost always see whales, and hear their song from the moment our ears are underwater and we've calmed enough to actually listen.
I don't know if there are more species, but I have positively identified Southern Right and Humpback whales last week, and quite a few are accompanied by calves.

For divers that have not been in the water for a long while and need to get back underwater gradually, and for divers that are enthusiastic about our artificial reef program, we organize lagoon dives.

I really like lagoon dives. First of all, there is the feeling of "being home". You might live in a nice area, be able to hike in a beautiful forest, but taking a short walk in your backyard does not take away from that beauty. Simply, what's in your backyard is different, and intimately known to you. You probably planted what's there to begin with, and looking at the birds visiting your bird-feeder from the comfort of your armchair is a different activity than going for a hike in the forest.

There are three spots in the lagoon where we go regularly, Legoland, The Graveyard and the Mouth.

We mostly go to the last one, the Mouth, for snorkeling sessions.
On the way, we often spot a flock of Flamingos.

The area covers the base of the rocky cliff, actually not "real" rocks, but ancient coral deposits, a length of about hundred by twenty meters, with barely more than three meters depth.
As you can see, it's well within the reach of beginner snorkelers.

The area is teeming with life. I have spotted Lion Fishes as small as a centimeter in length, among more mature ones of close to twenty centimeters.

There are also numerous eels, juvenile and mature.

Of course, it's not all about fish, there are also many crustaceans (Cleaner Shrimps, Hermit crabs), gastropods (Cowrie Shells, Nudibranch, Sea-Cucumber, Shaggy Sea-Hare) and of course all the flora.

A short distance away, we can observe Sea-horses, 

Pipefish and Razor Fish

Closer to the Water Sport Center, we have Legoland. So called because it consists of elements built with concrete blocs, used like one would use Lego blocks to build a playground.

The lagoon bottom is mostly flat sand, so any asperity will offer a refuge to fish and other creature from the fishermen, whose nets don't discriminate between edible and non-edible species, small or big individuals.

In my mind, the presence of so much fish life in the immediate proximity shows the artificial reef is beneficial to the fish population.

It's not uncommon to have a school of Kingfish circle around us on the way down.

At the bottom, we see quite a few resident Orangespotted Rockcod

Butterflyfish, Snappers, Parrotfish and many others I still haven't been able to identify.

The Graveyard is a different experience. Although the initial motivation in the construction of the reef was to provide a solid surface to which sea creatures would attach, the opportunity for having fun was too strong to resist. The shape of the concrete slabs evolved to resemble tombstones, and that's how the name of the reef was found. For a modest fee (about R100), you can inscribe your own tombstone (mother-in-law's names are popular, and so are the names of competing companies) and sink it yourself.

The rockcods like to hang at the foot of the tombstone.

The reef currently covers an area of over forty meters diameter, with dozens and dozens of tombstones. We also added a few "fish-houses" built with concrete blocks of the same model as Legoland. I have observed clouds of larvae in these fish-houses develop to juvenile fish.

This reef is a favorite destination for night dives, adding to the spookiness of the experience...

So when the tide table doesn't allow us to go out of the mouth, diving inside the lagoon can be an enriching experience.

Mantaaaaaa!

Big excitement! Shortly after we started descending, a Manta Ray came to see what all this agitation was about, and circled us for almost ten minutes.

The viz was rather good, so our group was spread over quite an area, and the Manta came over every single diver, more than once. We had all leisure to examine it, and the six Remoras that accompanied it.

This was really a good start of a dive that will remain in everyone's memory.

I didn't have my camera with me, so I'm relying on Gavin's generosity for the pictures in this post. One advantage to that is that for once there's a pic of me (hello Mom!) :

Gavin's mastery of the underwater colours is outstanding. Here is one of his pics, taken around 12m depth, using only natural light (no external lighting):

Fantastic conditions

This was a busy week-end with notable visits by a group from Maputo, and Trish and Graham stopping on their way through Africa.

The conditions were the best I've had in Bilene in the last month. The wind had shifted around quite a bit over the past few days, flattening the sea. The calm swell made the launch through the mouth very easy, the smoothest rides we've had so far.


As we dropped, a school of Kingfish circled around us. I'm not sure whether they are resident on the reef, or whether there's a different school every time we dive at Shark Alley.

More photos from the dive here

On this dive, I noticed what I think is an anemone, maybe a tube anemone, but if anyone could confirm, I would appreciate it. When approached, it retracts into the leathery foot very quickly.
If you look at the other pictures, there's another photo of a similarly behaving "anemone", of a different colour.

Some sad news: we went out to look at the seahorses, really struggled to find some, and while we were swimming around some of our group on the beach saw local fishermen with handfuls of seahorses they had just caught. My suspicion is thus confirmed: the seahorses in that spot have been fished out...

More about that in a different post...

A couple of dives...

There are very few of us on the boat today, so we load it with spare cylinders and head out for a double-tank dive.
The wind of the previous night has created a cross swell that is a little unpleasant for the ride, but it's still better than some of the conditions we had a couple of weeks ago.
Our first destination, since we enjoyed the dive there so much two days prior, is Shark Alley. On our previous visit, we explored the Northern side, so this time we drop on the South end of the reef.
The viz is not as good as two days ago, but we don't need that much to see the profusion of fish greeting us under the surface.
The reef on this side is very interesting, with huge boulders creating overhangs and caves where the fish seek refuge.
We even see a honeycomb moray eel completely out of its hole, inside a shallow cave.

There is also a profusion of Twobar Clownfish, small and big (Cobus and Ian remark they've seen a pair of the biggest they've ever seen on this dive)

We surface after 46 minutes, having gone all the way to Pride Rock, with still some air to spare, but wanting to keep a decent amount of bottom dive for our next dive.
After changing cylinders, comparing our impressions about the dive, having a bite to eat (for some of us), and stretching our Surface Interval Time, we slowly travel to Babylon.
As is usual on this reef, a huge amount of fish, big and small, awaits us.  One notable encounter is with a curious Trumpetfish:

and of course the encounter with the Scorpionfish just before the end of the dive:

Clearing water, and disappearing seahorses...

Went for a double tank dive today, at Shark Alley (which is becoming my favorite site) and Pride rock. The visibility has been steadily (although too slowly for my taste) improving, each dive reveals bigger and bigger pictures of the reefs structure.
As in previous dive, there was an amazing quantity of fish, big and small, which made the dive very enjoyable.

In the late afternoon, we went to our usual spot in the lagoon to spot the seahorses, and I found it extremely difficult to find one, where we spotted dozens yesterday...

(More Seahorse photos here )

Was it too late in the day, was the tide wrong, did they all go to a party where we weren't invited?

Let's see tomorrow if we see them at a different time.
