Weekly Photo Challenge: Three’s A Crowd

I thought it might be fun to participate in the Weekly Photo Challenge since the theme this week is one of my specialties!  These yellow coral gobies make their home inside an empty beer bottle.

Are You My Mother?

Spring is in the air and it seems like all the little animals are twitterpated.  Outside my kitchen window, two sparrows are building a nest, and a robin has already laid eggs in my wisteria bush.  Under water, similar developments are taking place.  Each time I dive, I look for animals with eggs, or nests of eggs.  The attraction of documenting new life is irresistible to me.  Perhaps it is my maternal instincts, but I often wonder if these little creatures ever know who their mother is?

Cardinal fish are fascinating in that the male fish will gather all the eggs in his mouth and brood them until they hatch.  He will periodically open his mouth wide, and aerate the eggs.  When they are pink, as in the image above, they are newly laid.  Later, the eggs will turn silvery and the eyes of the fry will be visible, as in the image below.  In this case, the babies may hatch to discover who their father is, but wonder about mommy.

Another parent who stays with its eggs until they hatch is this tiny goby.  Sometimes, both parents will care for the eggs, aerating them with their fins.



Both male and female yellow bearded gobies stay with their eggs until they hatch as well.  These fish lay their eggs deep inside the hard corals where they live to help protect them from predators.

And in the image below, a male and female robust ghost pipe fish await the arrival of their brood which are developing inside a pouch which the female has made between her pelvic fins.  The interesting thing here is that after the eggs have been deposited into this pouch, small branches will grow from her skin and attach to the eggs.  It is thought this acts as a sort of umbilical cord.  Although the robust ghost pipe fish is related to other pipefishes such as sea horses, it is the female, not the male who has the brooding pouch.

Clearly, there are responsible mothers AND fathers in the kingdom of the fishes.  We may never read about the tiny newborn fish who wandered around asking the kitten, the hen, and the dog, the cow and the snort, “Are You My Mother?”

Hair, Hair, Everywhere!

One of the freaky things about the under water world is discovering creatures that are “hairy.”  It never occurred to me that a fish could have hair, or a lobster or crab for that matter.  The interesting thing about hairy critters is that they blend in so well with their environment which is often made up of hair-like substances.  One of my favorites is the hairy frogfish.


The Striated Frogfish (Hairy Variation) has all these filiments growing from it.  They live in or near filamentous algae and at about one or two inches long, are very hard to see.  They have a fuzzy lure atop the head which they use to attract fish.  The frogfish has a very quick strike and can eat another fish it’s own size.

Another hairy fish is the Yellow coral goby, or bearded goby.  It lives inside hard coral where it hides from predators.  This fish definitely has a cute factor with it’s chin stubble and big blue eyes.  What a heart breaker.


The Shortpouch Pygmy Pipehorse is an interesting critter that is covered with various sized skin flaps.  It can be found living in sea grass and is only a few centimeters long.


This fun critter is a Hairy Squat Lobster.  It lives on giant Barrel Sponges and blends into it’s pinkish environment.  It’s carapace is covered with numerous long white bristles.

The Algae shrimp (nicknamed hairy shrimp) are some of the most obscure tiny critters to be found.  They are only about 1/4 inch at best.  If you look closely, you can see that both specimen have a belly full of eggs.

One day I hope to have an image of a hairy octopus (Yes!  Octopus!)  And the Lacey Scorpionfish has a coif that rivals the most cryptic of marine animals.  The amazing world of hairy creatures continues to inspire me, and lures me back to the water again and again in search of it’s crazy inhabitants.

California’s Underwater Halloween Party

To celebrate Halloween and in honor of all things orange, I thought it might be fun to go through my archives in search of images of orange sea life found in California.  Of course, the top prize goes to last weeks post of the orange and black nudibranch that made it’s first appearance in California.  But surprisingly, there are quite a few creatures of the orange persuasion in the sea!

 The Geribaldi is the California State Marine Fish.  It is found mostly in shallow coastal waters in Southern California.


The male fish builds a nest of red algae every year in the same place, attracting females to lay their eggs.  The female will check out several nests before she decides on one.  These fish protect their nests while they are brooding.   They are the largest of the damsel fish.  I have found that I can attract them to me by tapping two rocks together.  They are curious, and unafraid of divers.

When a juvenile, the Geribaldi has bright electric blue spots.

The Spanish Shawl is a nudibranch that takes the cake when it comes to dressing for Halloween!  It’s orange mane and purple robe put it fully in the Halloween category, but those maroon colored rhinophores make it very eccentric.

Sea Stars are a rarity nowadays along the California coast because of the devastating Sea Star Wasting Syndrome that has been wreaking havoc on our echinoderms.  I found this guy just last month, and was intrigued by it’s texture and color.  He is certainly a survivor as he is the only sea star I have seen for months.

This Skeleton Shrimp gets double Halloween points.  One for being a skeleton (well not really, but they look like they are), and one for being mostly orange.  These guys are tiny (only 5 to 8 mm long), and have so much character.

Here is a Bluebanded Goby that is found all over the place in Catalina.  They are tiny and this one was hiding in a deserted tube worm’s hole.  When he poked his head out, he seemed to have his tiny teeth barred.

Last, but not least, and certainly not all of the orangey types, is a Simnia.  This is a kind of snail that pulls its foot up over it’s shell.  It is very hard to see while under water because it appears brown and is perfectly camouflaged with the sea fan it lives on.  But just add light, and WOW!


Waterdog Photography, Brook Peterson wishes you a happy and safe kickoff to the upcoming holidays!
