Off the coast of Massachusetts, an ordinary lobster trip suddenly turned into a once-in-a-lifetime encounter with nature.
On a summer morning off Salem, a New England fisherman looked down at his traps and realised one lobster inside was unlike anything he had seen before. Its shell wasn’t the usual muddy brown. It was a vivid, electric blue that seemed almost artificial against the grey Atlantic swell.
A strange flash of blue on the deck
In July 2025, lobster fisherman Brad Myslinski was working aboard his boat, the Sophia & Emma, in the waters off Salem, Massachusetts. Among a routine haul of American lobsters, one animal stopped him in his tracks.
Instead of the standard brown‑green armour that blends with the rocky seabed, this lobster glowed an intense bright blue, from its claws to the tip of its tail. For a fisherman who spends countless days at sea, that kind of surprise is rare.
Marine educators estimate that only about one in two million American lobsters is blue, and the chance of actually catching one is closer to one in 200 million.
The figures come from specialists at the Northeastern University Marine Science Center in Nahant, just up the coast from Salem. The odds are so low that many commercial fishers will work their entire career without seeing a single blue lobster in their traps.
From trap to science centre star
Realising he had found something extraordinary, Myslinski decided not to sell the lobster. Instead, he contacted a local science teacher, who put him in touch with staff at the Marine Science Center.
There, the lobster was welcomed not as seafood, but as a living teaching tool. Students from a nearby high school gave it a fitting name: Neptune.
Neptune now lives in a rocky touch tank at the centre. The tank mimics the subtidal environment off New England, with stones, crevices and a constant flow of seawater. Around the bright blue crustacean swim tautog (a local reef fish), along with sculpins, crabs and green sea urchins.
Neptune behaves like any other lobster: it loves mussels, prefers to stay tucked under rocks and only ventures out when it feels safe.

The animal’s rarity lies almost entirely in its colour, not in its behaviour or anatomy. In every other respect, it is a standard American lobster, Homarus americanus, the same species that fuels a multimillion‑dollar fishery from Maine to Canada.
Why this lobster is electric blue
The question that fascinates visitors is simple: how can a wild lobster be such a piercing shade of blue?
Scientists at the centre point to a rare genetic mutation. Neptune’s body produces an unusually large amount of a protein complex called crustacyanin. This protein is found in many crustaceans, including lobsters, crabs and prawns.
How crustacyanin colours a lobster
- Crustacyanin binds to pigments inside the lobster’s shell.
- In typical lobsters, that mix produces a brown‑green colour.
- When crustacyanin is overproduced, the pigment shifts towards an intense blue.
- When cooked, the protein breaks down and the underlying red pigment appears, which is why all lobsters turn red in the pot.
For Neptune, this overabundance of crustacyanin pushes the colour into what staff describe as “electric blue” — far brighter than the muted blue tinge sometimes seen in the fishery.
The mutation doesn’t seem to harm Neptune; it simply makes the lobster stand out dramatically in a habitat where camouflage is usually the key to survival.
A whole palette of rare lobsters
American lobsters are typically a mottled brown‑green. That shade provides effective camouflage among rocks, algae and sand on the seafloor. Yet every so often, genetics shuffle the deck in a surprising way.
Marine biologists and fishers have documented a small but striking list of colour variants:
| Colour type | Approximate rarity | Notes |
|---|---|---|
| Blue lobster | ~1 in 2,000,000 | Caused by excess crustacyanin, like Neptune |
| “Cotton candy” lobster | ~1 in 100,000,000 | Pastel pink and baby blue shell |
| Calico lobster | Very rare | Speckled with orange and black patches |
| Yellow lobster | Extremely rare | Bright yellow or golden shell |
| Albino (white) lobster | Among the rarest | Lacks pigment entirely, ghost‑white appearance |
Neida Villanueva, a doctoral student working in Professor Jonathan Grabowski’s lab at Northeastern, notes that these unusual colours arise from different genetic quirks affecting pigments and shell proteins. Each rare specimen tends to draw intense media attention, partly because the colours look almost too perfect to be natural.
Long‑lived crustaceans with a cellular trick
Beyond their colours, American lobsters fascinate scientists for another reason: their potential lifespan. Some individuals may reach ages of 80 to 100 years, outliving several generations of fishers working the same grounds.
One key factor is an enzyme called telomerase. In many animals, including humans, telomerase activity declines with age. That decline is linked to the shortening of telomeres, the protective caps at the end of chromosomes, and to gradual cellular ageing.
Adult lobsters keep producing telomerase throughout their lives, allowing their cells to keep dividing and repairing for far longer than in most animals.
This doesn’t make lobsters immortal, but it helps explain why some can grow very large and old, provided they avoid predators, fishing gear and disease. In theory, a lobster like Neptune could live decades in captivity under stable conditions.
Why blue isn’t always an advantage in the ocean
For Neptune, life in an aquarium is far safer than life on the seabed would have been. That intense blue, impressive to human eyes, could be risky in the wild.
Predators such as cod or larger fish focus on movement and contrast. A bright blue shape on a dark rock may be easier to spot than a mottled brown shell. In nature, standing out is rarely a good survival strategy unless it signals toxicity, which is not the case for lobsters.
By living in a research centre, Neptune avoids those risks and becomes a conversation starter. Families see a living example of genetic variation, marine ecology and sustainable fishing all in one tank.
From viral photos to real‑world science
Images of rare lobsters often circulate widely online, sometimes stripped of context. A striking photo may go viral, while the underlying science stays in the background. Centres like the one in Nahant try to use that initial burst of interest as a teaching moment.
Visitors who come to see “the blue lobster from the news” are introduced to broader topics: how commercial lobster fisheries are managed, how climate change affects the Gulf of Maine, and how local ecosystems function below the surface.
Neptune serves as a gateway to talk about genetics, climate, and the daily reality of working fishers in New England.
Key terms that make sense of the story
For anyone new to marine biology, a few technical words crop up around Neptune’s case. Understanding them helps make sense of what this lobster represents:
- Crustacyanin: a protein complex in crustacean shells that binds to pigments and changes their apparent colour, especially towards blue tones.
- Mutation: a small change in DNA. Most have no obvious effect, some can be harmful, and a tiny fraction, like Neptune’s, simply alter appearance.
- Subtidal zone: the area of seabed that remains underwater even at low tide. American lobsters usually live here, among rocks and crevices.
- Telomerase: an enzyme that maintains chromosome ends. In species like lobsters, continuing telomerase activity helps cells keep dividing.
What a one‑in‑200‑million catch tells us about chance
Stories like Neptune’s highlight how much of nature is shaped by probability. The genetic mutation itself is rare. The lobster then had to survive long enough to grow, end up in a specific fishing ground and finally wander into the right trap on the right day.
For fishers, these odds put such animals into a different category. While the rest of the catch is part of their livelihood, a specimen like Neptune becomes something else entirely: a reminder that even in a heavily worked sea, there are still surprises waiting just below the surface.
