How are Diadema sea urchins ecologically beneficial?

Sea urchins in the genus Diadema are among the dominant grazers and forces of erosion of the substratum in shallow tropical reef environments. They compete with other herbivores and also influence the interactions between algae and coral.

Can you pee on a sea urchin sting?

The biggest problem is that sea urchin spines often break off under the skin, so be very careful when plucking out the spines. Soak in vinegar—Urban legend has it that human urine, or pee, will treat both jellyfish stings and sea urchin spines, but peeing on the afflicted area does not actually work.

What is the role of sea urchins in the ecosystem?

Sea urchins are important herbivores on coral reefs, and in some ecosystems they play a critical role in maintaining the balance between coral and algae. Their role can be especially important on reefs where other herbivores (such as parrotfishes and rabbitfishes) have been depleted.

What is the ecological importance of sea urchins?

Sea urchins play an important ecological role in the delicate balance of marine ecosystems. As it feeds mainly on algae, present on the rocky substrate at a depth between the surface and about 80 metres, it is classified as one of the most efficient herbivores (or grazers) in the marine environment.

What is Diadema setosum?

Diadema setosum is a species of long-spined sea urchin belonging to the family Diadematidae. It is a typical sea urchin, with extremely long, hollow spines that are mildly venomous. D. setosum differs from other Diadema with five, characteristic white dots that can be found on its body.

Is the Diadema setosum the oldest sea urchin?

Morphological analysis confirms this conclusion, adding weight to the concept of D. setosum being the most basal of the Diadema and possibly the oldest extant species in the genus. Like other venomous sea urchins, the venom of Diadema setosum is only mild and not at all fatal to humans.

What triggers the spawning of Diadema setosum?

Other cues, such as the phases of the moon have been observed to affect the spawning of D. setosum populations. The species has been found to trigger spawning events in concordance with the appearance of a full moon. Evolutionarily, Diadema setosum is considered one of the oldest of the known extant species in the genus Diadema.

What are the characteristics of Dendrocystis setosum?

A few other minor characteristics in D. setosum include bluish spots on the organism’s genital plates and similar blue spots ( iridophores) arranged in linear fashion along its test. An apical ring is absent in the species, along with calcareous platelets on its apical cone.
