Pearl Fish 1:  “It must clean inside of the sea cucumber because he cleans up the whole ocean, he is the ocean’s janitor.”

Pearl Fish #2:  “How does he do that?”

Pearl Fish #1:  “It moves along the ocean floor using its tentacles.  It takes in sand, eats the organic matter (carbon containing compounds such as living things), and poops what is left.”

Pearl Fish #2:  “Ugh.”

Pearl Fish #1:  “No.  The poop is good for the ocean.  It helps in making coral reefs and might reduce acidification ( making the water more acidic, which is not good).”

Pearl Fish #2:  I don’t see any gills.  How does that thing breathe?”

Pearl Fish #1:   “Through its 🤬!  But that is not the only weird thing going in and out of its 🤬.

Pearl Fish #2:  “What do you mean?”

Pearl Fish #1:  “Well.  When a sea cucumber feels threatened, scared or even too full, it will do a strange thing to fix it called evisceration (removing its own body parts).   When a sea cucumber eviscerates, it throws out its inner organs, mostly through its 🤬.   But the organs aren’t lost.  The sea cucumber grows them back in about one and one half weeks.”

Pearl Fish #1:  “Let’s go meet my friends.  They are inside the sea cucumber-he can hold about 15 of us.”

Paint the bumpy part white. Then I painted the area between what would become the teeth red for gums, but you could easily leave it white too.

If your egg carton has holes in the top you can just hot glue a piece of cardboard over them and then paint the rest green.

Cut off the last two bumps on both egg cartons. This makes a spot for you to put in your hand (fingers on tops and thumb on the bottom), so your dragon can open his mouth to eat the villagers talk. If I had been thinking I would have cut off the back of the egg carton before painting it.

One of the sections you cut off becomes the dragons eyes with a little black paint and hot glue.

Then you should have something that looks a bit like this. I made hits be a dragon, but he could easily be a dinosaur or an alligator too.

The next step is to make a neck to hide your arm. If you are lucky you have an old long sleeved shirt that matches lying around, so you can just cut off the sleeve and use it. (I happened to have an old green sweater that worked well! If not you have to sew a sleeve. Then you hot glue it around the entire back of your dragon (including his teeth; it helps keep him together).

All you have to do now is insert your hand and put on a show (or eat the other puppets)!

The girls really enjoy their dragon, but he is a bit big for their little hands. This puppet is best operated by an older child or an adult. In our case Daddy makes the best dragon. Eli really enjoyed him and kept coming up to the puppet, yelling "BITE," and giggling as he ran away!

Giant clams are huge molluscs that can grow up to 1.5 meters and weigh as much as 230 kilos. They have zigzag shaped opening with large protruding brilliant blue iridescent lips. Many are found in the Great Barrier Reef off the north-eastern coast of Australia.
Can Giant Clams Eat Humans?
Giant Clam - Description What Do Giant Clams Look Like?

The Giant clam is the world's largest sessile (attached to a fixed location) mollusc in the world. It has a rather uninteresting hinged double-sided shell with a serrated zigzag pattern on it. The two halves of the shell hinge on one side and are held together by strong muscles. This shell may have blotches of colour. The most notable characteristic of this clam, besides its huge size, is its beautiful blue iridescent lips. Because of these large lips, the giant clam cannot, unlike other clams, close its shell completely. At the centre of its blue lips it has two siphons (tubes) which it uses to suck in water and also eject waste.

Giant Clam's Big Blue Lips Why the Giant Clam's has Blue Lips

The giants clam has special iridescent cells, called iridocytes, in its lips that give them their beautiful blue and aqua colour. These brilliant coloured lips actually serve a very useful purpose - they direct sunlight into the interior of the clam providing the sunlight necessary for algae it hosts in its lips.

These clams live in a symbiotic relationship with algae. This symbiotic relationship is referred to as mutualism, because both clam and algae mutually benefit from their partnership. Typically the shallow coral reefs the clams live on is exposed to levels of sunlight strong enough to kill the algae. But by hosting the algae within its body, clam provides the algae with a safe and sunny environment. The algae in return produce sugars and proteins which they share with the clam.

The clam can open and close its shell thereby expanding or contracting the surface and angle of its mantel to manage the amount of light penetrating to its microscopic algal tenants below. It can also lighten or darken its colour pigmentation to regulate light penetration.

Why are its lips blue?

The reason the giant clam's lips are blue is because the clam's iridocytes transmit mainly red and blue light, the wavelengths that the algae photosynthesise most efficiently, and deflect much of the green and yellow wavelengths because it's of no use to the algae. This is what gives the clam's lips their colour. Interestingly the algae themselves are a dull grey-brown colour.

Giant Clam - Diet What Do a Giant Clams Eat?

Giant clams are filter feeders that suck in large quantities of water through an inhalant siphon which is usual a flat hole in its mantel. The water is circulated over its gills where a sticky mucus causes microscopic plankton and other particulate organic matter from the water to adhere to it. Tiny hair-like structure called cilia continuously sweep these food particles towards the clam's mouth and into its digestive system. Digestive waste is excreted through an anus. And filtered water is ejected through an exhalent siphon with a tubed spout.

Giant clams also supplement diet this with sugars (glycerol) and proteins produced by the microscopic algae that they host within their mantel. The algae feed on carbon dioxide and other products supplied by the giant clam and using photosynthesis with the light directed to them by the clam's iridocytes produce these nutrients for the clam.

Giant Clam - Habitat Where Do Giant Clams Live?

Giant clams are sedentary animals that are found in the relatively shallow water not more than 20 meters deep. Once a young clam larvae finds a suitable location on the reef it attaches itself to the reef and stay there for the rest of its life. They inhibit inhabits reefs and lagoons with good sunlight penetration.
Great Barrier Reef - Coral, Animals, Plants and Attractions
Giant Clam - Reproduction & Life Cycle Giant Clam Babies

Giant clams are hermaphrodites. They have both male and female reproductive organs but they don't self-fertilise.

They release millions of eggs and sperm into the water through their siphon where they intermix with eggs and sperm from other giant clams and are fertilised. This spawning, known as broadcast spawning, is synchronise by chemical signalling using a substance referred to as the spawning induced substance that individual clams release into the water signalling their readiness to spawn. Many individuals then time the release of their eggs and sperm to have the best opportunity of being cross-fertilised by other clams. Spawning is most common during the incoming tide and lasts for 30 to 180 minutes. .

Once fertilised the eggs float in the water for about 12 hours before the larvae hatch out and immediately start to develop a shell. Within a few days the little clams descend to the bottom the ocean and for the first few weeks will move from place to place in search of a suitable location. It will then attach itself to the ocean floor and remain there for the rest of its life.

Even though million upon millions of eggs and sperm are produced very few clams survive into adulthood. A giant clam reaches adulthood in 4 to 9 years and can live for up to 100 years.

Giant Clam - Attack Legend Can Giant Clams Eat Humans?

There are many unfounded legends, myths and tales about attacks by giant clams. These tales usually claimed that these giant clams gobbled up unwitting divers. A U.S. Navy diving manual even gave detailed instructions on how to free oneself form the grip of a giant clam.

Today the giant clam is known to be non-aggressive. It will only close is shell in self-defence. It is possible that a human could get a limb caught during such a closure and drown as a consequence. But this is very unlikely because the clam closes its shell very slowly, giving a person plenty of time to extricate themselves.

Giant Clam - Threats & Predators What Treats Do Giant Clams Face?

Marine Predators

Giant clams are preyed upon by many animals much smaller than themselves. They include snails, eels and starfish that nip off pieces of the giant clam's lips.

Humans

One of the major treats facing giant clams are humans who harvest them for their shells, as displays in their aquariums and for their flesh which is considered a delicacy in some countries. This has led to a drastic decline in the number of these beautiful clams world-wide. The giant clam is listed as vulnerable to extinction.

Giant Clam - Conservation Status

The giant clam is considered to be vulnerable because of humans. As with all plants and animals the giant clam is protected in the Great Barrier Reef sanctuary.

Evisceration

Evisceration is a method of autotomy  (removing one's own body parts) involving the ejection of internal organs used by animals as a defensive strategy. Sea cucumbers (Holothuroidea) eject parts of the gut in order to scare and defend against potential predators such as crabs and fish.

While these crabs are aggressive and prey on other small invertebrates, they also have a number of predators themselves. According to the Alaska Department of Fish and Game “Species which prey upon hard-shelled Dungeness crab include humans, sea otter, octopus and Pacific halibut; larger Dungeness crabs and staghorn sculpin are important predators on juvenile Dungeness crabs in some areas.” In terms of humans as a predator, many commercial fisherman consider dungeness crab as one of the most valuable fisheries. However, according to the Ocean Conservancy although they are a tough species environmental conditions may also be a large threat,  “Ocean acidification changes the chemistry of our oceans, scientists and fishermen are just beginning to understand how it will impact this important species."

Dungeness crabs have a lot of appendages. Describing the crab's anatomy, The National Park Service reports “Two pairs (antennae) are for touch and smell”, this helps them locate their prey. “A number of modified appendages act as a mouth, used for cutting, picking, sorting and pulverizing food”, this allows them to easily catch and eat their prey.  “The pincers, the most recognizable appendage, are used for grasping, tearing and defense." This helps them defend against predators. Lastly, they state a very cool fact " Crabs are able to regenerate lost appendages."

Most Dungeness crabs live in the Pacific Northwest, their name comes from Port of Dungeness Washington. According to the Ocean Conservancy “Dungeness crab prefer sandy or muddy parts of the ocean floor, especially around eelgrass beds.” BioExpedition explains that “They are a brown color that allows them to easily blend into their surroundings.” This makes sense as they live in sand and mud. Bio Expeditions further explains “They feature a very hard shell that they molt several times over the span of their life so that they are able to continue growing." Some Dungeness crabs will live up to 10 years! That's older than me!
