What are sea pens?
Sea pens can be one of the most unique creatures in the ocean environment. They are sea cnidarians who live in clusters and resemble one individual creatures that are very reminiscent of an old -fashioned pen. These creatures, known as polyps, cooperate in favor of the whole organism.
Sea pens come in different colors and sizes. They can grow up to 2 feet (60 cm) in length and often occur in tropical waters, but can also be found in colder waters. Their color ranges from dark orange to yellow and white. Some even express the characteristics of bio-liniscence at night.
found on the bottom of the ocean DNA, their shape is very distinguishable. They can be found at a depth of up to 225 feet (68.5 m). They are present in both coastal waters and in deeper coastal waters, where the stream is calmer. However, because they are hanging feeders, they need some type of stream to move the food to their grip.
although the sea perajs are very easy to overlook and notThey can be much known about them, they can be one of the most abundant types of Cnidarians on the planet. In fact, one researcher estimates that the weight of the tissue in the sea loners would be equal to or overcome the weight of all other Cnidarians together. Given this abundance, it is somewhat surprising that there was no further research on them.
Sea pens open in full beauty at a time when they begin to feed. They are suspension feeders, which means it depends on the driving of organic particles and zooplankton to gain their energy. Once the sea pen is feeding, then retreat and download. This process usually takes place several times a day.
Sea pens are particularly vulnerable to some predators. Sea stars, especially very much by sea pens. Sea pens can also fall into a number of diseases, including a parasitic form of green algae. However, if it remains without preditation or illness, sea pens can live andPs 15 years old.
Sea pens can also be maintained in aquariums and tropical varieties can be very popular. However, they do not have to be recommended for amateurs because they have a significant amount of space and expertise in their care. They must be fed with a special meal and need a sand base at least 1 foot (30 cm) to give them a good anchor.
