Lysmata amboinensis is an omnivorous shrimp species known by several common names including the Pacific cleaner shrimp. It is considered a cleaner shrimp as eating parasites and dead tissue from fish makes up a large part of its diet. The species is a natural part of the coral reef ecosystem and is widespread across the tropics typically living at depths of 5–40 metres (16–131 ft).
Lysmata amboinensis can reach a body length of 5–6 centimetres (2.0–2.4 in) and have long white antennae. Mature shrimp are pale in colour with longitudinal bands on their carapace; one central white band with wider scarlet red bands on either side. The shrimp has a long larval stage and unusual sexual maturation, initially being male but becoming a functional hermaphrodite once mature.
Lysmata amboinensis is popular in home and public aquaria where it is commonly referred to as the skunk cleaner shrimp; this is due to its striking colours, peaceful nature, and useful symbiotic cleaning relationship which can also be witnessed in captivity.
Adult shrimp can reach a body length of 5–6 centimetres (2.0–2.4 in) with two pairs of long white antennae. The body and legs are pale amber in colour with longitudinal bands on the carapace: one central white band is flanked by wider scarlet red bands. There are several symmetrical white spots on the red tail. The most anterior antennae fork into two making the shrimp appear to have three pairs of antennae. As with all decapods there are 10 pairs of walking legs, with the most anterior pair having forceps (pincers). Anterior to the walking legs are a pair of white maxillipeds used for feeding. Underneath the thorax behind the walking legs are paired pleopods (swimmerets) used for swimming and brooding eggs.[Lysmata amboinesis have a pair of stalked eyes though experiments suggest they have coarse vision and are colour blind; this low spatial resolution makes it unlikely they can see the striking patterns of other shrimps or tropical fish.
Distribution and habita
Lysmata amboinensis is native to coral reefs across the tropics including the Red Sea and the Indo-Pacific Ocean. They live on tropical coral reefs between depths of 5–40 metres (16–131 ft) and are typically found in caves or reef ledges.
Life cycle
Lysmata amboinesis lay eggs which the adult shrimp keep attached to their pleopods. The early larvae are called nauplii which hatch into more developed larvae called zoeae and go through a free-floating planktonic stage. During this time they feed on other plankton and moult through 14 identified stages growing to approximately 2 centimetres (0.79 in) in length over 5–6 months. At this point the larvae will settle and metamorphose into a more mature form, though not yet the adult state. This is achieved after several moults which occur every 3–8 weeks.
Each shrimp starts out as a male, but after a few moults will become a hermaphrodite allowing them to function as both male and female in interactions with another shrimp; these shrimp have no pure female form. This form of sexual maturation is scientifically described as 'protandric simultaneous hermaphroditism' and is unique to Lysmata shrimp amongst other decapod crustaceans. In one spawning, adult shrimp will lay between 200–500 eggs which are initially attached to the pleopods and are greenish in colour; the eggs swell and lighten in colour before hatching and a few will turn silver on the day of hatching. The eggs hatch around dusk releasing 3–4 millimetres (0.12–0.16 in) long larvae into the free-floating pelagic zone.
Behaviour
Lysmata amboinesis do not live in large groups, more often in pairs, and while omnivorous it is believed they derive much of their nutrition from cleaning parasites and dead tissue from fish. Their mating behaviour has been observed in captivity where it involves little ritual: a pair of fully mature hermaphroditic shrimp will alternate moulting timing, mating occurs shortly following a moult when one shrimp acting as the male will follow the other acting as the female which will brood the fertilised eggs; when the next shrimp moults the roles, and therefore apparent sex, will reverse.
In captivity L. amboinesis have been seen to be socially monogamous showing such aggression that if they are kept in groups of more than 2 individuals one pair will kill the rest. While they are not generally seen in large groups in the wild it is unknown if they are socially monogamous in their natural environment.
Symbiosis
Lysmata amboinesis, like other cleaner shrimp, has a symbiotic relationship with 'client' fish in which both organisms benefit; the shrimp gain a meal from eating parasites living on large fish and the clients benefit from the removal of parasites. Cleaning organisms including shrimp and fish can congregate in one location on a reef in what is called a "cleaning station" which fish will visit when required; cleaning shrimp perform a rocking dance from side to side to signal their services when fish approach. Removal of parasites under captive conditions happens mainly at night though it is unknown whether this is due to shrimp or host fish behaviour.Additionally, cleaning services provided by the shrimp aid wound healing of injured fish supporting the symbiosis hypothesis. L. amboinesis is also commonly found living in caves with their client fish, such as moray eels, providing the shrimp with protection from predators.
Because of the benefits of cleaner shrimp to the fish they clean, Lysmata amboinensis and other species have been suggested as potentially useful to aquaculture.
Common name
Lysmata amboinesis within the marine aquarium trade is commonly referred to as the skunk cleaner shrimp, white-banded cleaner shrimp or scarlet cleaner shrimp due to its appearance, however this last name is also sometimes used for Lysmata debelius.
In the aquarium
Many species of Lysmata, including L. amboinesis, are commonly kept in salt water aquaria; they are safe and beneficial since they will clean both the tank and fish but not harm corals. For these reasons they are often kept in both home and public aquaria for educational purposes, sometimes in 'touch pools' which allow visitors to put their hand in the water so the shrimp will clean their hand.
Despite significant efforts L. amboinesis remains difficult to culture in captivity, though adults will regularly spawn eggs. The cycle from spawning to adult form takes approximately 6 months during which time the vast majority of larvae die. As such most shrimps sold in the aquarium industry are wild-caught, this has led to concern about the negative effects of their removal on natural reefs though there is currently no evidence of an effect.
Mespilia globulus, commonly known as the Globular Sea Urchin, is a small, spherical sea urchin found in tropical shallow reef habitats. It's characterized by its radially symmetrical, globe-shaped body and relatively small spines, usually brown, red, or dark in color. This sea urchin can grow up to 5 cm in diameter and is known for its algae-eating habits.
Here's a more detailed description:
Size and Shape: The Globular Sea Urchin is small, with a maximum diameter of about 5 cm. Its body is spherical, making it resemble a small, spiny ball.
Spines: It has relatively short spines, which can grow up to 2 cm long. These spines are typically brown, red, or dark in color.
Habitat: Mespilia globulus is found in shallow, tropical reef habitats.
Diet: It is a herbivore, primarily feeding on algae at night.
Behavior: During the day, it often hides on rocks or in crevices, emerging at night to graze on algae. It also exhibits a unique covering behavior, using sponges, shells, and algae.
Appearance: The urchin's radial symmetry and short spines are distinguishing features.
Other Names: It is also known as the Sphere Sea Urchin or the Tuxedo Urchin
Lysmata debelius is a species of cleaner shrimp indigenous to the Indo-Pacific. It is popular in the aquarium trade, where it is known as the fire shrimp, blood shrimp or scarlet cleaner shrimp.
Lysmata debelius grows up to 3 centimetres (1.2 in) long, with males and functional hermaphrodites appearing similar. It has a red body, with conspicuous white antennae and white tips to the third to fifth pereiopods. There are white dots on the cephalothorax and legs; white dots on the abdomen distinguish L. splendida from L. debelius.]
Lysmata debelius is one of a group of species in the genus Lysmata that has the role of a cleaner shrimp in reef ecosystems, alongside L. amboinensis, L. grabhami and L. splendida.[5] It is a popular aquarium pet.
Lysmata debelius is a hermaphrodite and therefore any two individuals may mate. The hatching of eggs, moulting, and copulation cycle is identical to that of L. wurdemanni, yielding weekly batches of zoeae from each pair.

Pavona corals are a genus of colonial, stony corals known for their various growth forms and common names like "Cactus Coral," "Potato Chip Coral," or "Lettuce Coral". They are part of the Agariciidae family and are distinguished by having clearly defined septocostae connecting corallites, resulting in a flower-like pattern on their surface. Pavona species exhibit a range of colors and growth forms, including columnar, club-shaped, or plate-like colonies.
Here's a more detailed look at Pavona corals:
Key Features:
Colonial:
They grow in colonies, forming various shapes like plates, branches, or columns.
Stony Corals:
They are a type of hard coral, meaning their skeletons are made of calcium carbonate.
Corallites:
They have shallow depressions called corallites, which are the individual polyp chambers within the colony.
Septocostae:
These are radial structures connecting the corallites, creating a distinct pattern on the coral's surface.
Zooxanthellae:
They contain symbiotic algae called zooxanthellae, which provide them with nutrients through photosynthesis.
Growth Forms:
Pavona corals can exhibit different growth forms, including columnar (Pavona clavus), plate-like (Pavona cactus), and branched (Pavona frondifera).
Examples of Pavona Species:

Corythoichthys haematopterus (известна като мрежовидна морска игла или драконолицева морска игла) е вид малка тропическа морска риба от семейството на морските игли и морските кончета (Syngnathidae). Тя се отличава със своето издължено тяло, специфични шарки и интересен начин на размножаване.
Разпространение и местообитание
География: Среща се широко в тропическите води на Индо-Тихоокеанския регион — от източното крайбрежие на Африка до Вануату, Южна Япония и Северна Австралия.
Дълбочина: Обитава изключително плитки води, най-често между 0 и 3 метра (понякога до 21 метра).
Среда: Предпочита защитени зони с пясъчно дъно, каменисти наноси (debris/rubble) и леко тинести рифови лагуни.
Размер: Обикновено достига максимална дължина до близо 20 см.
Окраска: Тялото е бледо или жълтеникаво, покрито с тъмни вълнообразни линии, които образуват мрежовидна структура. Опашката е червеникава с бял кант.
Биофлуоресценция: Видът притежава способността да флуоресцира. При осветяване със синя или ултравиолетова светлина, тялото му излъчва ярко жълт блясък, което вероятно помага за комуникация и камуфлаж.
Ophiarachna incrassata, widely known as the Green Brittle Star or Thick-armed Brittle Star, is a large, predatory marine echinoderm native to the Indo-West Pacific. Highly active and robust, it is famous among aquarists for its striking appearance and surprising predatory behavior.
Physical Characteristics
Size: It is one of the largest brittle stars, with a central disc (body) that can measure up to \(5\) cm (\(2\) inches) in diameter. Its five arms can grow up to \(20\) to \(25\) cm (\(8\) to \(10\) inches) long, giving the entire creature a striking span of up to \(50\) cm (\(20\) inches).
Coloration: Its base color ranges from muted or bright green to brownish-green. The central disc is typically adorned with lighter yellowish dots or markings, and the arms are often lined with alternating whitish to yellowish-white spines.
Habitat and Range
Natural Range: Widespread throughout the tropical Indo-West Pacific, spanning from the Red Sea to Hawaii and the coasts of northern Australia and Japan.
Environment: Found in shallow, tropical littoral waters, usually at depths of less than \(10\) meters (\(30\) feet). They are benthic dwellers, commonly found on reef flats tucked among coral rubble, rocks, seagrass beds, and algae.
Diet and Behavior
Feeding Habits: Unlike many brittle stars that strictly scavenge, Ophiarachna incrassata is a highly capable predator. While they will eat detritus, zooplankton, and meaty leftovers, they also actively hunt and capture small fish and other invertebrates using their thick, flexible arms.
Movement: They use their arms to crawl rapidly across the seafloor, making them surprisingly fast for echinoderms.
Temperament: They are solitary and generally secretive, often hiding in rock crevices during the day. They are known to be somewhat aggressive toward other tank inhabitants and should be kept with caution in reef aquariums containing small, sleeping fish
Common Names: Peppermint shrimp, Candy Cane shrimp, Caribbean cleaner shrimp.
Size: Small, reaching about 5.0 to 6.5 cm (2 to 2.5 inches) in length.
Appearance: Translucent bodies adorned with a network of vibrant, bright red and pink longitudinal/vertical stripes (resembling a peppermint candy) and long, white antennae. Eggs are distinctly bright green.
Habitat: Native to the Western Atlantic Ocean, Caribbean Sea, and the Gulf of Mexico; they thrive around coral reefs and rocky areas.
Diet & Behavior: They are peaceful, bottom-dwelling scavengers that eat detritus, uneaten food, and are primarily known for eating the pest anemone Aiptasia.
Peppermint Shrimp (Lysmata wurdemanni) are small, peaceful saltwater crustaceans native to the Western Atlantic and Caribbean. They are highly prized in the marine aquarium hobby for their striking candy-cane-like appearance and their natural ability to prey on pest glass anemones (Aiptasia).
Physical Characteristics
Size: Reaches a maximum length of about 5.0 to 6.5 cm (2 to 2.5 inches) as adults.
Coloration: Their bodies are mostly see-through/translucent, beautifully accented with vivid red and pink stripes spanning the length and sides of the shrimp
Eggs: Females carry distinctively bright green eggs.
Behavior & Habitat
Habitat: These invertebrates reside in coastal waters, often sheltering in the crevices of coral reefs and among submerged marine vegetation.
Diet: As scavengers, they consume decomposing organic matter, uneaten fish food, and nuisance Aiptasia anemones.
Temperament: They are highly social, aggregate-living shrimp. However, they are naturally skittish and require ample hiding spots in captivity to feel secure.
Reproduction: They are simultaneous hermaphrodites, meaning adults can reproduce as both male and female, though they cannot self-fertilize.
Aquarium Care
In the marine aquarium trade, L. wurdemanni serves as an important member of the clean-up crew. While traditionally sold as a single species, taxonomic revisions reveal that what is sold as the "Peppermint Shrimp" often includes closely related species (like Lysmata boggessi), all of which exhibit very similar appearances and anemone-eating behaviors.
The DaVinci Ocellaris Clownfish (Amphiprion ocellaris) is a captive-bred designer morph prized for its unique, swirling white markings that resemble a painter's brushstrokes. Each individual features a completely unique pattern of connected and curvy white bands.
