Life in the under-anemone: Because looking isn’t actually seeing

Posted by | PADI underwater naturalist, The Incredible Showcase, Underwater Naturaliast Course, Underwater Photography | No Comments

It was sometime around the second week of March when something special had taken place, a big change, in the lives of a pair of false clownfish.

Living at about five meters deep over at Nemo’s reef, with beige-coloured tentacles and a pinkish-purple base, sat a magnificent sea anemone. Everything in the anemone appeared to be much the same, the fish couple who lived with it were busy cleaning out the anemone, lapping up its dying tentacles and parasites, while the anemone stood firmly guarding the couple from harm. The anemonefish were constantly swimming through the anemone’s tentacles, as was usual, to help it breathe. The anemone took what the anemonefish pooped and the fish ate what the anemone pooped. Business as usual! And yet something was markedly different in this anemone home.

There was something going on in one corner of the anemone that kept taking the fish pair back there. Was somebody hurt? Were they hiding a stash of food?

No… it was babies!

Attached to a cleared patch of rock under the tentacles of the anemone were hundreds of pairs of eyes on the tops of alien-like bodies, swaying gently in the current. In addition to protecting the anemone and themselves, the anemonefish must now protect their offspring.

They looked to be quite old already, which could only mean that they had been laid about a week before. It would be just a few more days before full moon would approach and larval fish would emerge. This meant focussed and dedicated work for the devoted father who was responsible for their care. While the female continued to take care of the anemone and daily duties, he concentrated on the babies, vigorously fanning the water with his fins, oxygenating, cleaning and doing everything required to make sure they survive. Both parents were invested.

A clownfish once hatched will have to live out its plankton phase until it is ready to find and settle into an anemone of its own and take on the forces of the underwater universe.

As dive professionals we sometimes think twice before talking about certain animals in our pre-dive briefings because we feel divers might find them too common or ordinary to be specifically mentioned. As we grow in dive experience, there is a natural tendency to create a hierarchy of coolness that we set for the marine life that is out there and the animals that we wish to see. Novelty, rarity and massiveness are definitely key factors in how high up in the list animals are positioned, and those that are seen often enough are further down, closer to the more ‘beginner diver stuff’.

There is definitely an appeal is seeing manta rays, sharks and turtles. They are enigmatic, extraordinary and closer to extinction than a damselfish. This extraordinary nature of the marine world, however, does not end here. There are so many phenomenal animals, interactions and communities that occur so commonly, we often fail to really see them entirely. And the loss is ours.

No two reefs or animals or behaviours are exactly the same when seen twice, even the most ordinary of things. That is just how dynamic the ocean truly is. Now you might ask- if there is so much beauty and wonder in the ordinary, why is it that we don’t see it? Perhaps we aren’t looking carefully enough. Perhaps we do not know what to look for. There is no special skill or talent required to do so. The secret is curiosity and patience. Wait, observe and soon, the animals will let you into their extraordinary world.

A peek into the sex lives of the stonefish.

Do You Love Me? A peek into the sex lives of the stonefish.

Stonefishes may be the most venomous group of fishes in the world, they may have some of the most potent ‘verrucotoxin’ venom ever studied and a full blown sting from a stonefish might kill you in under an hour, but should one powerful defence mechanism define their entire existence?

Stonefishes are primarily solitary animals that use extensive camouflage and stealth to catch their prey, typically fish. Seeing a stonefish fully out in the open is not particularly common, let alone finding one that is actively moving around. Unless it is mating season!

From what has been observed in the wild, stonefish males can go to elaborate lengths to court a female. Once she lays her egg mass on the seabed, the male swims over her eggs to deposit his sperms. Sometimes courtships can turn into an elaborate congregation where multiple males try to win over a female.

The stings produced by the dorsal spines of stonefish can induce intense pain, respiratory weakness, damage to the cardiovascular system, convulsions and paralysis, at times death. But hey, even the most brilliantly venomous animals can have a – I’m just a boy, standing in front of girl, asking her to love him’-moment, as we see in this beautiful video of male stonefish chasing after a female, captured by our stellar divemaster Saw Montu in Nemo’s Reef!

Aren’t you rooting for the hobbling young male in this pair of lovers?!

Dining etiquette for an Octopus | The Incredibles Showcase

How do octopus eat their prey

Dining etiquette for an octopus: Dig in with all hands!

Nemo’s reef is a fantastic place to spend hours watching these animals just,be. We follow them quietly, as they go about doing their daily things around the shallows of Nemo’s. That alone is one lifetime of diving right there! People often make the mistake of getting way too close to an octopus. Sure, it is sitting there in its crevice, changing colour in response to divers and that is rather cool! But what would be even cooler and perhaps much less disruptive for the octopus, is if we were to curb the excitement and give the animal enough space to get back to its life. This can in fact be plenty times more extraordinary a sight to behold than a tense octopus hiding in a hole! Here we see a young octopus that frequents the ‘first barrel sponge rocks’ area at Nemo’s reef. All of us have met this octopus over the past few weeks and she/he is now very comfortable around divers. When we first saw it, a diver was ten inches away from it with a camera, as it hid inside a crevice, perhaps thinking to itself – Hurry up mister, I’m starving and you’re in my way. As soon as said mister left the scene, the octopus was on the move! We suppose one can identity an octopus with a ravenous appetite by how thoroughly it inspects each rock, tickling every crevice simultaneously with every arm. Note how it expands each arm, turning its entire body in to a large web-like umbrella to trap any molluscs, crustaceans or tiny fish that get flushed out during its invasion.Once prey is in hand, an octopus might crush it, pry it open, or drill a hole in it, drain in some toxins or simply slurp it up, depending on the nature of its catch. Owing to its highly efficient, powerful and thorough hunting technique, an octopus on the hunt is almost always surrounded by a mob of other fish-a mix of allies and competitors possibly. Here we see a few juvenile groupers, wrasses, goatfishes and a tiny cloud of exasperated damsels. Isn’t this simply fascinating?

The Angler Flounder (Asterorombus Intermedius)

The Art & Science Of Floundering About

 

We all know what a flounder is, and we’ve surely heard of anglerfish, but what in the world is an angler flounder? As though the flounder and angler were each not sci-fi enough, evolution has fashioned this beautiful animal, a.k.a Asterorombus intermedius!

With intricate and elaborate head-to-toe camouflage and a stiff lure protruding from the tip of its mouth, the angler flounder takes the most effective adaptations of two very good predators and blends into something like a super-predator of the sandy bottom. But, why go through all that effort? Is procuring a meal really that difficult in the wild?

For many of us humans these days, finding food would probably mean, cooking a meal after heading over to the market, going to a restaurant, opening the fridge for a quick bite, making a phone call and ordering in (in increasing order of tech sophistication but in decreasing order of per capita effort?). You and I don’t really have to forage, chase or hunt for our food, sustenance and survival. But animals in the wild do, every single time, requiring sophistication and effort! As prey get smarter and harder to catch, predators have no choice but to evolve better strategies to make sure they have that meal on their plate. It is never an overkill.

The angler flounder on the hunt has heightened senses- it swivels each eye, keeping a look out for potential prey- a watchman goby or partner shrimp maybe? Hidden from view by its granular pattern and colour, carefully it crawls over the sandy bottom with webbed fins, waving its bait, casually but concertedly-come fishy-fishy-fishy…

Camouflage for a flounder is extremely effective but also a lot of work. There is the technical aspect of the chromatophores and pigments that need to be constantly redistributed amongst the flounder’s tissues, just the right amount and at just the right time, to give it the right colour, texture and hue. This requires the thinking aspect, where should I position myself? What should I blend in as? Am I on rock or sand or both? Of course, this is where the cleverness aspect comes in- there comes the goby, it is going to turn in my direction in…3…2…1… BAMMM! Meal.

While we might appreciate the beauty of these animals and their wild schemes, it helps to also appreciate all that goes in the making. Take something like camouflage, for instance. The next time you are trying to get too close to a flounder or scorpionfish or any camouflaged animal for that matter, for the thrill of a better view, a photograph or to instigate movement, remember that disturbing it will not only blow its cover, but also cost it a day’s meal!
