As a marine biologist with a love for sand dollars, I am often asked about the size of these delicate sea creatures.
The biggest sand dollar measures up to 4 inches (10 cm) in diameter.
Sand dollars are fascinating creatures that belong to a group of animals called echinoderms, which also includes sea stars and sea urchins.
They are found in shallow waters along the coasts of many countries and are popular among beach-goers for their unique shape and intricate patterns.
Sand dollars come in a range of sizes, from tiny specimens that are less than an inch in diameter to larger ones that can grow up to five inches across.
However, there is one species of sand dollar that stands out for its impressive size.
The Species
The species that holds the record for the largest sand dollar is the Mellita granti, also known as the sea pancake. This species is found in the Gulf of California, off the western coast of Mexico.
The Size
The largest Mellita granti ever recorded measured an impressive 4.7 inches in diameter.
This is a remarkable size for a sand dollar, considering that most species are much smaller.
The sea pancake gets its name from its flat, round shape, which resembles a pancake.
The Appearance
The sea pancake is an incredibly unique-looking sand dollar.
Its body is thin and flat, with a smooth, white surface that is covered in small spines.
The spines are arranged in a radial pattern, which gives the sand dollar a star-like appearance.
The sea pancake also has a distinctive mouth located in the center of its body, which is surrounded by a ring of tiny teeth.
The Habitat
The sea pancake is found in shallow, sandy areas in the Gulf of California.
It is often found in large groups, which can make for an impressive sight.
These sand dollars are filter feeders, meaning that they use their spines to capture tiny particles of food from the water.
The Conservation Status
Like many marine species, the sea pancake is facing threats from human activities.
Overfishing and habitat destruction are major concerns for this species, as well as for many other marine animals.
It is important that we take steps to protect these creatures and their habitats, before it is too late.
Conclusion
