A combination of literature has been used to create this description.
| General |
- Hyalinella punctata lives in colonies that grow closely attached to the substrate
- A colony is only lightly branching and consist of thick cylindrical tubes that are closely aligned
to the substrate
- The base is formed by branching tubular extensions that hold the polyps at regular (1 mm)
distances. Zooids are in open connection with each other
- The zooids are relatively short and broad and are often tightly packed .
- The wall is transparent, jelly like and never chitinous
- Often distinctive cystid openings that are striped (ringed) all around .
- No separation walls (septa) between zooids, all zooids are closely in contact.
- Tubes that grow parallel are likely to adhere and merge
- Although the chitine zooicum is thick, soft and translucent it cannot be confused with the
gelatinous species (like C. mucedo or P.magnifica) as the gelatinous species never form branching
colonies

| Color |
Clear, light colored to transparent |
| Tentacle crown |
Horseshoe shaped tentacle crown with 40 to 70 tentacles. |
| Size |
One zooid is 1 mm long A colony maximum ?? cm in diameter |
| Statoblasts |
Both floating (floatoblasts) as sinking (sessoblasts) are formed.
Both are round without tubercles
The floatoblasts have a broad float ring
The statoblasts are found in the main tubes |
