Is the sea apple an animal or a living plant?Unique marine life

Mondo Science Updated on 2024-02-01

In the vast ocean, there are countless mysterious creatures hidden, among which there is a creature called the "Sea Apple", whose name sounds like a fruit, but in fact it is very different from the apple we are familiar with. What kind of legend of sea creatures is hidden behind this strange name?

First, let's clear up a common misconception: sea apples are neither apples nor plants. In fact, it is a round and large sea cucumber that belongs to the animal kingdom. To be more precise, sea apples are one of the echinoderms, which are specifically classified in the genus Hyacucumber, Crunopodae, Guashenaceae, and Pseudopterocarpus. The peculiarity of this creature is its spherical or ovoid appearance, as well as the mouth wrist located at the top, around which many tentacles grow. These tentacles are not only a tool for sea apples to hunt, but also a medium for them to communicate with the outside world.

Despite its enticing name, the sea apple has a far cry from the fruit. Its body takes on a variety of vibrant colors, including yellow, pink, and orange, among others, which shimmer in the ocean. Sea apples can often reach around 10 centimeters in size, which makes them stand out among the many marine creatures.

Among marine life, sea apples are known for their unique filter-feeding properties. They feed mainly on plankton, such as rotifers and other tiny organisms suspended in the water. This filter-feeding lifestyle allows sea apples to play an important role in the marine food chain. However, it is interesting to note that despite the ability of sea apples to prey on small plankton, they do not consume much of their daily food intake due to the limitations of their digestive system.

In captivity, sea apples may require specific foods to sustain their vital activities. This includes frozen, liquid, or dried phytoplankton, among others. Breeders need to pay close attention to the food needs and feeding environment of sea apples to ensure their health and growth.

In addition to their unique appearance and eating habits, sea apples have another striking feature: they are able to move. Unlike most plants, sea apples have some ability to move autonomously. Although they are not very fast, this ability allows Sea Apples to escape danger or find a more suitable living environment when necessary.

Sea apples are mainly found in the waters of Australia, a vast expanse of sea that provides them with abundant food** and a suitable living environment. However, with the continuous changes in the marine environment, the survival of sea apples also faces certain challenges. Therefore, protecting the marine environment and maintaining biodiversity is essential to ensure the survival of marine life such as sea apples.

When raising sea apples, keepers need to be careful not to mix them with marine organisms with hard spines. This is because sea apples have a soft body surface and are susceptible to damage. In addition, in order to ensure the healthy growth of sea apples, farmers also need to regularly monitor the water quality, temperature and other feeding conditions, and adjust the feeding strategy in time.

It is worth mentioning that sea apples have important scientific value in the study of marine life. Through the study of sea apples, scientists can gain insight into the physiological structure of marine organisms, their habits, and their interactions with the marine environment. These studies not only help to reveal the mysteries of marine life, but also provide an important scientific basis for marine ecological protection.

Overall, sea apples are a unique and fascinating sea creature. They are distinguished by their bright colors, peculiar shapes, and unique filter feeding properties. However, with the continuous expansion of human activities and the increasing changes in the marine environment, the survival of marine organisms such as sea apples is also facing unprecedented challenges. Therefore, we need to pay more attention to and protect these precious marine biological resources, so that they can continue to write their own legends in the blue ocean.
