Renate Khalaf’s Cleaner Shrimp – Urocaridella renatekhalafae

Renate Khalaf’s Cleaner ShrimpUrocaridella renatekhalafae – a clear cleaner shrimp in the family Palaemonidae. It was identified as a species new to science in 2018, and was named in honor of the discoverer’s mother, Renate Khalaf.

Two important notes:
1. Shows that not everything you see has been identified yet
2. That you can name thing for your mom.

Etomology – Oura Greek meaning “tail” and Latin Carid meaning “crustacean”

Spotted Porcelain Crab

Spotted Porcelain Crab, Neopetrolisthes maculata

Spotted Porcelain Crab –  Neopetrolisthes maculata, lives as commensal in large sea anemones. Sitting among the stinging tentacles and filtering planktonic food from the currents.

Entomology Neopetrolisthes – neo Greek for “new”, petro – Latin & Greek for “rock”, olisthes – L & G for “slippery”
Entomology Maculata comes from the Latin root macula, meaning “spot, stain”

Ambon Crinoid Shrimp a master class in camouflage

Amboinensis Crinoid Shrimp - Periclimenes amboinensis
Amboinensis Crinoid Shrimp – Periclimenes amboinensis

Ambon Crinoid Shrimp or Feather Star ShrimpPericlimenes amboinensis – Hiding among the arms of the crinoid this little shrimp wondered if I could see him.

Small in size, between 1 – 1.5 cm, they can be highly variable in colors – Yellow, White,Black,Blue,Orange,Green,Brown and in combination of colors, all depending on the host Crinoid that it lives on, for camouflage.

Crinoids, also known as “feather stars” or comatulids are harmless, colorful creatures. They are among the most ancient and primitive of ocean invertebrates. Crinoids are Echinoderms (Phylum Echinodermata, meaning “spiny skin”). To feed, they extend their arms to catch bits of plankton or detritus (waste matter) passing in the current, making them “suspension feeders”.

Etymology of amboinensis Means “from Ambon” the island in the Lesser Sunda Islands, Indonesia.

Etymology of Crinoid – Greek word krinon, “a lily”, and eidos, “form”

Whitemargin Stargazer Fish

WhitemMargin Stargazer - Uranoscopus sulphureus
Whitemargin Stargaser look’n up at ya

Whitemargin Stargazer fishUranoscopus sulphureus – Stargazers are not a fish to mess with. They have double-grooved poison spines behind the operculum and above the pectoral fins and wounds can be quite serious. Stargazer possess electric organs located in a specialized pouch behind the eyes and can discharge up to 50 volts, depending on the temperature of the water at the time! Because stargazers are ambush predators which camouflage themselves and some can deliver both venom and electric shocks, they have been called “the meanest things in creation”. The fish is often locally known as the mother-in-law fish.

Inhabits reef flats but is rarely seen because it lies buried in the bottom most of the time, with only the eyes showing. When buried, the cirri on the edge of the mouth serve to keep out the sand during respiration. The oral lure is used to attract the prey within striking range of the mouth.

This little fellow was only about 15cm long but they get to a maximum length of 45.0 cm.

Etymology: Uranoscopus: Greek, ouranos = sky + Greek skopein = to watch

Spider Decorator Crab

Spider Decorator Crab - Camposcia rutusa
Spider Decorator Crab – Camposcia rutusa

Spider Decorator CrabCamposcia retusa
The choice of noxious or stinging organisms as decorations implies that attaching them provides protection from predators by aposematism (warning) rather than by crypsis (camouflage), and there is direct observational evidence for this, e.g. that octopuses in tanks avoided decorated crabs. The relationship of crab and organisms such as sea anemones used as decoration may be mutualistic, offering protection to the crab and food to the anemone.

The crab tears a piece of adornment in its claws, chews it, and then rubs it firmly on its body until it catches on the “Velcro-like hooked setae”, curved hairs which permit camouflage materials to be attached. The carefully chosen decoration is supplemented by cryptic behavior, such as remaining still by day, and freezing when predators approach.

Yellow Barred Jawfish

Yellowbarred Jawfish – Opistognathus randalli


Yellowbarred – Tiger – Gold specs jawfish, Opistognathus randalli
Found singly with just his head showing in rock lined burrows on sand and rubble areas. They feed mainly on benthic crustaceans, invertebrates and zooplankton.

Jawfish are usually found in self-constructed burrows with just the head showing waiting for their prey, they have huge mouths for the size of head.
After mating the males incubate the eggs in their mouths!

The Golden Fireworm - Chloeia flava
Golden Fireworm – Chloeia flava

The Golden FirewormChloeia flava#PolychaeteA segmented #bristleworm belonging to the family #Amphinomidae. They have an elongated body made of 37 visible segments, each of them has a distinctive ocelli (simple eye), which is purple or dark color with a white outline and placed in the middle of the upper side. Small gills are present on both external side of the back just before the bristles and on almost all the segments.The body is covered laterally with calcareous spines or setae, they have bristle aspect which are whitish, fine, sharp and venomous.

Candy Crab

Candy Crab - Hoplophrys oatesi

Candy CrabHoplophrys oatesi – A very colorful crab that grows from 1.5 to 2 cm. It lives on various species of soft coral in the #Dendronephthya genus. It camouflages itself by mimicking the colors of the polyps among which it hides. It adds further camouflage by attaching polyps to its carapace. Colors vary depending on the color of the coral, and may be white, pink, yellow or red.

The first pair of legs of this species has small claws. The body has pointed spines with a red and white pattern, similar in appearance to the host coral.

Funeral Nudibranch

The Funeral Nudibranch - Jorunna funebris
Funeral Nudibranch

The Funeral NudibranchJorunna funebris, gets is name from the black and white coloration. It feeds on a blue sponges (Neopetrosia sp.), which makes it poisonous, and able to secrete chemicals that make them distasteful or toxic.

As a members from the family Discodorididae they are able to retract its gills into a gill pocket. Many species are able to break off part of their mantle to distract predators. They generally have a narrow foot compared to the wide mantle skirt.

Halimedia Crab - Huenia heraldica
I blend in

Introducing Huenia heraldica, the Halimeda Crab. Its ability to camouflage in Halimeda algae (duh!) is nothing short of remarkable.
Halimeda algae is a smart object to mimic since very few organisms enjoy dining on this hard algae.

This species is a decorator crab; It sometimes attaches rigid fronds of halimeda algae to its rostrum in front of the eyes to enhance its camouflage.
