A Rare Lobster Discovery on the Coast of Cape Cod
Fishermen off the coast of Cape Cod recently made an unexpected discovery when they caught a lobster that was unlike any other. This particular lobster had a striking feature: its body was perfectly split down the middle, with one side appearing in the typical brown colour and the other side bright orange. Such a unique colouration is extremely rare, occurring in only one in 50 million lobsters.
The lobster was initially intended for the Wellfleet Shellfish Company in Eastham, Massachusetts. However, it has since been donated to the Woods Hole Science Aquarium in Falmouth, where it will be studied further. According to the company, the lobster is currently being housed in holding tanks at the Marine Biological Laboratory while the aquarium undergoes construction. Once the facility reopens, the lobster will be put on display, giving visitors a rare opportunity to see one of nature’s most fascinating anomalies.
Most American lobsters are a muddy brown colour, which helps them blend into the murky depths of the ocean. However, genetic defects can lead to more unusual colours. These mutations affect the production of certain pigments, resulting in different hues. For example:
- Blue lobsters occur at a rate of one in two million and have a defect that causes overproduction of crustacyanin.
- Orange lobsters, which appear to be already cooked due to their bright red carotenoid pigment, occur at a rate of one in 30 million.
- Albino lobsters are the rarest, with odds of one in 100 million. They are born completely white and do not turn red when cooked.
The Science Behind Split Colouration
Julia Studley, a biologist at the Woods Hole Aquarium, explained how split colouration occurs. She stated that this phenomenon happens when two fertilized, unlaid eggs come into contact with each other, causing one to absorb the other. This results in a lobster with two sets of genetic information, allowing it to store different colour pigments on either side of its shell.
This unique genetic occurrence offers a glimpse into the complexity of natural genetics. Studley added that the lobster serves as a reminder of how intricate these mechanisms are and how important they are in creating the diversity we see in the world around us.
Public Reaction and Other Unusual Discoveries
The discovery has captured the attention of many online. Social media users have expressed their excitement, with comments such as “Very cool!” and “Cuuuuute!” One user even joked, “That was incredibly unshellfish of you to donate it!”
This recent find follows another rare lobster sighting off the Massachusetts coast. A female lobster with a distinctive ‘calico’ pattern—bright orange with black and yellow speckles—was caught. Experts estimate the odds of catching a calico lobster at one in 30 million. Named Jackie, the lobster was donated to Northeastern University’s Marine Science Center in Nahant.
Jackie’s vibrant appearance is the result of a unique combination of chemical compounds, including astaxanthin, which gives lobsters their red colour and shrimp their pink hue. According to Sierra Munoz, a science educator at the center, the interaction between these pigments and proteins creates a rare mottled or freckled look.
Such unusual discoveries continue to intrigue both scientists and the public, highlighting the wonders of marine life and the importance of preserving and studying these natural phenomena.
