Copepod/Class
What are the characteristics of copepod?
Copepod Characteristics
- Copepod size varies from 2 mm to 1 cm in length.
- The body of copepods is teardrop-shaped, contains a thin, almost transparent exoskeleton, and two pair of antennae (shown below).
- Copepods lack a circulatory system and gills.
- Waste products are excreted via specialized maxillary glands.
What is a nauplius in crustaceans?
A nauplius (plural nauplii) is the first larva of animals, classified as crustaceans. Nauplius larvae belong to the phylum Arthropod. It body consists of a thorax and abdomen, head and telson*1. This organism has a single, median eye at the front of its head.
What adult form develops from a nauplius?
branchiopodal development As the nauplius feeds and grows, it gradually changes into the adult form—the body becomes segmented, or jointed, and additional limbs…
Do copepods have a carapace?
Copepods lack compound (i.e., multifaceted) eyes. Unlike most crustaceans, they also lack a carapace—a shieldlike plate over the dorsal, or back, surface. Some species feed on microscopic plants or animals; others prey on animals as large as themselves.
Are copepods phytoplankton or zooplankton?
Tiny crustacean zooplankton called “copepods” are like cows of the sea, eating the phytoplankton and converting the sun’s energy into food for higher trophic levels in the food web. Copepods are some of the most abundant animals on the planet.
What kingdom does a copepod belong to?
Animal
Copepod/Kingdom
Is a copepod a Holoplankton?
What are Holoplankton? Holoplankton spend their entire lives as part of the plankton. This group includes krill, copepods, various pelagic (free swimming) sea snails and slugs, salps, jellyfish and a small number of the marine worms.
Is nauplius phytoplankton or zooplankton?
The nauplius is a zooplankton and feeds on detritus. As with all zooplankton, nauplii play an important role in the productivity of marine habitats.
Which group retains their Nauplius eye into adulthood?
Notostraca
Larval stages The eye is known for that reason as the “naupliar eye”, and is often absent in later developmental stages, although it is retained into the adult form in some groups, such as the Notostraca.
Is Nauplius phytoplankton or zooplankton?
What kind of organism is a nauplii?
A nauplius (plural nauplii) is the first larva of animals, classified as crustaceans. Nauplius larvae belong to the phylum Arthropod. It body consists of a thorax and abdomen, head and telson* 1 . This organism has a single, median eye at the front of its head.
What are the main features of a nauplius?
In some species, however, the naupliar stages are passed in the egg, and a cyprid larva is released into the plankton. The main features of a nauplius are a simple, unsegmented body, three pairs of appendages (antennules, antennae, and mandibles), and a single, simple, “naupliar” eye. Nauplius larvae are found in the life cycles of cirripedes,…
How many legs does a nauplius crustacean have?
In crustaceans the larva, called nauplius, does not differ substantially in mode of life or means of locomotion from the adult but has fewer appendages than the adult. A typical crustacean nauplius has three pairs of legs and an unpaired simple eye. Additional pairs of appendages and paired compound eyes…
What kind of body does a nauplius larva have?
reproduction branchiopodal development In branchiopod: Reproduction and life cycles …its life cycle as a nauplius larva, which has a simple undivided triangular body and three pairs of appendages: antennules, antennae, and mandibles.
