Physical Description

Data about Priapulida
  • sexual dimorphism
    Sexual dimorphism is a phenotypic difference between males and females of the same species. The prototypical example is for differences in characteristics of reproductive organs. Other possible examples are for secondary sex characteristics, body size and morphology, ornamentation and behavior.

Additional detail integument
  • integument
    integument differs between males and females. Includes the size, number, distribution or shape of cilia, scales, spines, hooks, bristles, feathers, hair, horns and teeth. Although not integmental structures, the antlers of mammals are included in this category because they are analogous in function to the sexually-selected horns and spines of other animals.

Ecology

Data about Priapulida
habitat
Additional detail intertidal zone
  • intertidal zone
    The area of the foreshore and seabed that is exposed to the air at low tide and submerged at high tide, i.e., the area between tide marks.

Additional detail marine biome
  • marine biome
    An aquatic biome that comprises systems of open-ocean and unprotected coastal habitats, characterized by exposure to wave action, tidal fluctuation, and ocean currents as well as systems that largely resemble these. Water in the marine biome is generally within the salinity range of seawater: 30 to 38 ppt.

Additional detail marine sediment
  • marine sediment
    Marine sediment is a sediment that accumulates in the flat or very gently sloping areas of the deep ocean basin floor. The three main types of marine sediment, also known as pelagic sediment, are siliceous oozes, calcareous oozes, and red clays.

Additional detail sediment
  • sediment
    Sediment is an environmental substance comprised of any particulate matter that can be transported by fluid flow and which eventually is deposited as a layer of solid particles on the bedor bottom of a body of water or other liquid.
