Sea Cucumbers Habits And Biology
Sea cucumbers ( Holothuroidea) are marine animals with elongated bodies and leathery skin containing a single gonad (reproductive gland). They are named for their resemblance to the cucumber plant.
What Do Sea Cucumbers Eat In The Wild?
Sea cucumbers benthic feeders, meaning they live on the seafloor and get their food from there. Sea cucumbers use their retractable tentacles to trap food material and insert it in their mouths for digestion.
Facts About Sea Cucumbers
Sea cucumbers don’t have a true brain. Instead, they have a variety of nerve endings found throughout the skin, giving them a sense of touch and a sensitivity to the presence of light.
Frequently Asked Questions (FAQ)
Most echinoderms spines are visible, whereas sea cucumbers have ossicles (small bones) embedded in their skin. These bones provide evidence to the clue of the species identity. You can examine the ossicles under a microscope.
Summary
There you have it! The answers to the question, “what do sea cucumbers eat?” and more.
Feeding
Sea cucumbers feed on tiny particles like algae, minute aquatic animals, or waste materials, which they gather in with 8 to 30 tube feet that look like tentacles surrounding their mouths. The animals break down these particles into even smaller pieces, which become fodder for bacteria, and thus recycle them back into the ocean ecosystem.
As Prey and Food
Sea cucumbers, particularly eggs and young larvae, are prey for fish and other marine animals. They are also enjoyed by humans, especially in Asia, and some species are farmed as delicacies.
Defensive Adaptations
When threatened, some sea cucumbers discharge sticky threads to ensnare their enemies. Others can mutilate their own bodies as a defense mechanism. They violently contract their muscles and jettison some of their internal organs out of their anus. The missing body parts are quickly regenerated.
Reproduction
Sea cucumbers can breed sexually or asexually. Sexual reproduction is more typical, but the process is not very intimate. The animals release both eggs and sperm into the water and fertilization occurs when they meet. There must be many individuals in a sea cucumber population for this reproductive method to be successful.
Sea Cucumber Diet
These animals aren’t the best hunters in the seven seas, preferring to scavenge their food rather than track it down. They generally eat a mixture of plankton, algae, and other small organisms, as well as waste. Sea cucumbers are omnivores, meaning that they eat both plant and animal material, depending on what is available.
Habitat
You can find sea cucumbers just about anywhere, although most of them prefer to stay in the shallows. Many sea cucumbers prefer tropical waters, making their habitats in the Indian Ocean and Pacific. Spot sea cucumbers on coral reefs and near sandbars, where they like to feed.
Amazing Organs
One of the fascinating aspects of sea cucumbers is how they defend themselves against predators. In addition to burrowing, sea cucumbers can shoot out their internal organs via their anuses and regrow new ones. By getting rid of their internal organs, sea cucumbers can temporarily confuse predators, allowing the sea cucumber to get away quickly.
Many Variations
In addition to being an ancient animal, sea cucumbers come in many different shapes and sizes. There are 1,250 known species of sea cucumbers. Since many of these incredible animals live on the ocean floor in the sea’s deeper regions, we might never know how many real varieties there are.
Feeding And Starvation In Sea Cucumbers
Like most marine invertebrates, sea cucumbers are capable of going for long periods of time without feeding before they show any outward signs of a problem. Even when they do show obvious signs of starvation, most people do not know what to look for in these unusual animals, and will likely miss the warning signs.
Sea Cucumber Defense Responses
I would not be doing anyone a favor if I did not point out that most popular aquarium texts have dire warnings about the dangers of including one of these animals in your reef tank (e.g., Delbeek and Sprung 1994a; Delbeek and Sprung 1994b; Fenner 1998; Paletta 1999; Tullock 1997).
So Which Cucumbers Are Safe For A Reef Tank?
Well, to recap what we’ve learned so far, different species tend to have different specific sets of chemical defenses, and those chemicals tend to have different effects on different potential predators.
