Is a starfish a herbivore or omnivore?
Nearly 2,000 species exist. Although the five-arm species is the most common, some sea stars have as many as 40 arms. Most are carnivores, using specialized organs to feed on mussels, clams and other slow-moving organisms.

Can u eat starfish?
After boiling it, remove it from the water, and break its limbs to eat the greenish-brown flesh inside. Deep-fried starfish is also a common street food in China.

Do starfish eat other starfish?
In addition to coral, these spiny stars eat worms, shrimp, clams, snails, and algae. They will even eat other smaller starfish. Their highly variable diet makes it difficult to feed them in aquariums. The best thing to do is to provide a steady supply of larvae and other zooplankton.
What group do starfish belong to?
class Asteroidea Starfish belong to the class Asteroidea, derived from the Greek words “aster” (a star) and “eidos“ (form, likeness, appearance). There are more than 1600 species of starfish alive today, and they have an important role in the community structure of the ocean floor.

What type is a starfish?
Classification: Starfish are also referred to as sea stars because of their star-shaped appearance. They are a part of the phylum Echinodermata and are related to sand dollars, sea urchins, and sea cucumbers. Echinoderms are found in nearly all marine habitats and constitute a major proportion of the biomass.
What type of animal is starfish?

Is a starfish a consumer or producer?
A starfish is a tertiary consumer in the ocean ecosystem.
Is it OK to touch starfish?
"Simply put, starfish absorb oxygen from water through channels on their outer body. You should never touch or remove a starfish from the water, as this could lead to them suffocating. "Sunscreen or the oil on our skin can harm sea creatures which is another reason not to touch them."
Why do starfish legs fall off?
(Phys.org) —A team of marine biologists has found that some starfish lose a leg when faced with too-warm environmental conditions.
What happens if you cut off a starfish arm?
While most species require the central body to be intact in order to regenerate arms, a few tropical species can grow an entirely new starfish from just a portion of a severed limb. Starfish regeneration across species follows a common three-phase model and can take up to a year or longer to complete.
Can a starfish come back to life?
Starfish can regenerate their own arms Arms can take months, even years to fully regenerate, so it has to be a pretty serious situation to lose one. Incredibly, if the severed leg is not harmed, it can heal itself and even regenerate – resulting in a genetically identical starfish.

Starfish themselves are not toxic, but they can contain toxins known as paralytic shellfish poison (PSP), which are produced by a species of algae.
Can starfish explode?
A 2006 report described the particle and field measurements of the Starfish diamagnetic cavity and the injected beta flux into the artificial radiation belt. These measurements describe the explosion from 0.1 milliseconds to 16 minutes after the detonation.
What happens if you cut a starfish in half?
While most species require the central body to be intact in order to regenerate arms, a few tropical species can grow an entirely new starfish from just a portion of a severed limb. Starfish regeneration across species follows a common three-phase model and can take up to a year or longer to complete.
