Stylophora pistillata, commonly called smooth cauliflower coral or hood coral, is a species of stony coral in the Indo-Pacific region. It has a branching growth form, with blunt-ended branches that thicken and become more massive as the colony matures. Corallites (the individual polyps' stony cups) are conical or hooded and partially submerged in the coenosteum (the stony framework of the colony). These corallites have a prominent, solid columella (the central column) and may have six primary and sometimes six secondary septa (stony plates forming the corallite wall). The coenosteum is covered in fine spinules. Colonies can be cream, pink, bluish, or green.
Key features of Stylophora pistillata:
Growth Form: Branching, with branches becoming thick and submassive.
Corallites: Conical or hooded, with a prominent columella and septa.
Colony Size: Up to 50 cm in diameter.
Color: Cream, pink, bluish, or green.
Habitat: Shallow water reef environments exposed to strong wave action.
Distribution: Indo-Pacific region
Symphyllia is a genus of large polyp stony (LPS) corals, characterized by their massive, dome-shaped or flat colonies with meandroid (brain-like) corallites. These corals are known for their diverse colors and patterns, often with contrasting colors between valley floors and walls. While the genus name Symphyllia is no longer taxonomically valid, with most species now classified under Lobophyllia, it's still used for CITES purposes.
Key characteristics of Symphyllia:
Colony Shape: Typically massive, dome-shaped, or flat, with meandroid valleys.
Corallites: Flabello-meandroid (brain-like), with ridges separating valleys, often with contrasting colors.
Polyps: Each corallite houses multiple polyps, indicated by the many mouth openings.
Color: Wide range of colors, often mottled, with contrasting colors between valley floors and walls.
Tentacles: They have long sweeper tentacles that can extend to sting other corals.
Habitat: Found on reef slopes and in protected areas of reefs.
Taxonomy: While the genus Symphyllia is no longer valid, it's still used for CITES (Convention on International Trade in Endangered Species) purposes, and many species have been reassigned to Lobophyllia.
Examples of Symphyllia species:
Symphyllia valenciennesi (now often classified under Lobophyllia), Symphyllia wilsoni (now often classified under Australophyllia), Symphyllia radians, Symphyllia agaricia, and Symphyllia recta.
Distinguishing Symphyllia from Lobophyllia:
Corallite Size and Structure:
Symphyllia species generally have larger, more branched corallites with more mouth openings compared to Lobophyllia.
Valley Ridges:
Symphyllia corallites often exhibit ridges dividing the interior surface (like a brain coral), while Lobophyllia corallites are often more separated.

The picturesque dragonet (Synchiropus picturatus) is a brightly colored member of the dragonet family native to the Indo-West Pacific: Philippines, eastern Indonesia and northwest Australia. It occasionally makes its way into the aquarium trade, where it is commonly known as the spotted mandarin, psychedelic mandarin or target mandarin.
Description
The picturesque dragonet may grow to a size of 7 cm in length. They have thick slime on their skin that inhibits many types of parasitic infection and minimizes the risk of disease following stress or physical trauma. This seems to help protect them from some other more aggressive fish.
Synchiropus picturatus is one of only two vertebrates known to have blue colouring because of cellular pigment, the other being the closely related Synchiropus splendidus. The name "cyanophore" was proposed for the blue chromatophores, or pigment-containing and light-reflecting cells. In all other known cases, the colour blue comes from thin-film interference from piles of flat, thin and reflecting purine crystals.
This species is quite harmless to humans and is quite peaceful with other species. The Picturesque dragonet is a marine animal that naturally lives at a temperature between 24-28 C.
A pair of Synchiropus splendidus, also known as the Splendid Mandarin, are characterized by their vibrant, multicolored appearance and unique body shape.

Turbinaria is a genus encompassing both brown algae and stony corals, each with distinct characteristics. Brown algae (like Turbinaria ornata) are marine organisms with an upright, tough thallus resembling a pinecone. They are often found in tropical waters, attached to rocks or coral heads, and can be invasive in some areas. Stony corals (like Turbinaria peltata) form colonies with corallites, which are the skeletal structures where polyps reside. They can be disc-shaped, vase-shaped, or plate-like, and are commonly found in reef environments.
Brown Algae (Turbinaria):
Appearance: Erect, radially branched, with blades or "laterals" that can be turbinate or peltate. The overall structure resembles a long pinecone.
Habitat: Primarily found in tropical marine environments, especially coral reefs.
Growth: Can be invasive in some areas, colonizing reefs and outcompeting other species.
Examples: Turbinaria ornata (Crowded or Crowned Sea Bells)
Stony Corals (Turbinaria):
Appearance: Colonial, with corallites (skeletal structures) arranged in various forms like discs, vases, or plates.
Habitat: Coral reefs in various depths and water conditions.
Growth: Can form large colonies, sometimes dominating reef ecosystems.
Examples: Turbinaria peltata (Disc Coral), Turbinaria mesenterina
Key Differences:
Structure:
Brown algae have a thallus (non-animal tissue) with blades, while stony corals have a skeletal structure with corallites.
Growth:
Brown algae can fragment and reproduce vegetatively, while stony corals reproduce sexually.
Invasiveness:
Some brown algae species are considered invasive, while stony corals are generally not considered invasive.
