My last post was about my dive on the HMAS Swan Wreck during my holiday in Dunsborough with a few friends. The next day (17 January 2010), I went snorkeling in the Yallingup Lagoon. That was my second snorkel in the calm waters of the Yallingup Lagoon. I snorkeled there the first time in 2007 and was immediately impressed with the ease of the snorkel and the variety of marine life in the lagoon. The lagoon is the best snorkeling spot (that I know) for anyone who just begins snorkeling.
The Yallingup Lagoon is truly an amazing spot to snorkel because you snorkel next to some big wave breaks. And regardless of the wind, the lagoon is more or less calm. In other words, even with the big waves in sight, you know you are pretty safe in the lagoon.
The lagoon is quite shallow, about one meter or less in most part of it. Underwater, I found some seagrass patches as well as places with sandy and reefy patches. The sandy area appeared to be good for swimming. So, the Yallingup Beach really caters for the surfers, snorkelers, and swimmers.
Another view of the lagoon. The two persons in the photo were standing at the edge of a shallow reefy area, with a sandy area (light blue) ahead of them. The dark blue/green areas are the seagrass.
In this snorkel, I explored the left end of the lagoon, which is near a carpark. The lagoon was teeming with marine life. As soon as you hit the water, you would start seeing schools of fishes swimming around you. But what really impressed me was that every time I turned over a rock I would see some marine creatures.
This rock had an elephant snail (red arrow; the black creature) (Scutus antipodes) and a feather star (green arrow) (Cenolia trichoptera) sitting on it.
On this rock, there were a number of abalones (yellow arrows), two elephant snails (green arrows) and a sea cucumber (red arrow).
A purple sea urchin sitting next to a feather star. I also saw a few slate-pencil urchins in rock crevices.
Another shot of the pretty feather star.
A brittle star - a wriggly, fast-moving little animal
Some tiny sea squirts under a ledge. Each of these little stalked spheres had two large holes. This resembles other stalked and attached sea squirts which have an inlet and an outlet for water in their body. Each of the small spheres was about 1 cm or less in diameter. Behind these little sea squirts were the feathery arms of a feather star (or maybe more than one star).
Over the reef and the seagrass areas, there were heaps of zebra fish (Girella zebra) swimming around. In this group, there was one or two breams too.
There were also many striped trumpeters (Pelates octolineatus) in the lagoon, although not as common as the zebra fish.
And I saw a few small schools of old wives (Enoplosus armatus). It was quite an incredible experience as I would have to free-dive a few meters to see a school of old wives in South Cottesloe. But here in the Yallingup Lagoon, they were just one or two feet below the surface.
Other fishes I saw over the seagrass and the seaweed-covered reef included western scalyfin, six-banded coralfish (moonlighter), western king wrasse, goatfishes, and trevally. I even saw a southern eagle ray resting on a sandy patch not far from shore. There were also quite a number of fishes that I still haven't worked out their names.
When you snorkel in the Yallingup Lagoon, you must check out what's waiting for you under the ledges of the shallow reef - lots of fishes. In this spot, I saw lots of old wives (at least 30 of them) and some stripeys (Microcanthus strigatus). Who would have thought you would find all these fishes in just three feet of water!
Finally, seeing this zebra fish with a metal hook through it's mouth sure gave me a little shock!
