Description
The Quadricolor Nudibranch T-Shirt puts black-and-white stripes and yellow-orange detail on a broad red sponge, bringing a small reef animal into bold view. Based on Cobi Hay Yacobi’s Red Sea photograph, the design combines a photographic nudibranch with an artistically interpreted sponge.

The animal behind the quadricolor nudibranch T-shirt
This striped animal is a marine gastropod mollusk, one of the nudibranchs whose adults lack an external shell. The plume rising from its back consists of gills used to breathe. At 2Dive, its striped appearance has earned it the nickname “pajama slug.”
Chromodoris quadricolor inhabits the western Indian Ocean, including the Red Sea, and eats sponges. Photographs often place it on red sponges, while observations also document feeding on dark ones. Explore the Australian Museum’s Sea Slug Forum account for its markings and feeding records. The scene here brings the animal and a red sponge into close view.
Photographic stripes on an artistic red sponge
The nudibranch retains its photographic detail on an artistically interpreted red sponge. Broad folded lobes form an irregular oval, and the animal sits toward the lower-right side. The shirt color shows around the open outline: White gives the red a light surround, while Black and Navy provide a darker setting. A small 2Dive logo sits below the artwork.

Chromodoris quadricolor T-shirt fabric and artwork
The Bella+Canvas 3001 is a unisex jersey T-shirt with short sleeves, a crew neck and a retail fit. White, Black and Navy use 100% Airlume combed and ring-spun cotton. The light, breathable fabric weighs 4.2 oz/yd² (142 g/m²), making the shirt an easy choice for everyday wear.
A ribbed knit collar, tapered shoulders and side seams shape the garment, with a tear-away label at the neck. Use the measurements below to compare it with a shirt you already enjoy wearing. The garment and artwork measurements serve different purposes: one guides fit, while the other tells you how much of the front the design occupies.
Including the small logo below the artwork, the print measures approximately 11.00 x 9.58 in (27.9 x 24.3 cm) on L to 5XL. It scales down proportionally to about 91% on M, 82% on S and 75% on XS.

Wear Chromodoris quadricolor as a small discovery
Chromodoris quadricolor offers a different kind of marine shirt from a large fish silhouette. The red shape is easy to notice first, with the striped animal adding the smaller discovery. Choose it if you enjoy artwork that has a clear overall form and something more to examine within it.
Keep the rest of an outfit simple when you want the sponge outline to read clearly. Compare the preview with an open overshirt or jacket you already wear, checking how much of the artwork remains visible. The Chromodoris quadricolor design can be the colorful piece in an otherwise quiet combination.
For a gift, consider someone who searches for nudibranchs on dives or enjoys photographing tiny subjects. Chromodoris quadricolor gives that interest a specific expression.
