A deep sea crab that lives on the ocean floor
  • noun
  • Specialized
: geryónido
  • The biology of geryonids is fascinating, as these deep-sea crabs have adapted to live on the ocean floor.

Examples

  • As the world demand for crustacean meat of all kinds continues to rise, interest has grown in the potential for commercial exploitation of deep-water geryonid crabs.

    Academic text (1992)
  • Chaceon granulatus is apparently a very large geryonid, with maximum weights of 2.02 kg and 1.51 kg recorded for male and female specimens, respectively.

    Academic text (1992)
  • Presently, there are two major geryonid fisheries in the Atlantic.

    Academic text (1992)
  • A brief review of the present status, distribution, and fishery potential of Pacific geryonids in general is included.

    Academic text (1992)
  • Individual archipelagoes in the Western Pacific possess relatively small areas at suitable depths for geryonid exploitation. Collectively, however, this area must be considerable.

    Academic text (1992)
  • The recorded depth range (250-900 m) is similar to that of other geryonids, but the large numbers of females caught below 700 m are atypical.

    Academic text (1992)
  • It is possible that similar populations of geryonids exist on the slopes of several Indo-Pacific archipelagoes.

    Academic text (1992)
  • Manning (1990) has noted that red geryonid species are often found in deeper water than tan ones; this tendency has now been recorded intraspecifically for C. granulatus.

    Academic text (1992)
  • Commercial fisheries targeting geryonids have increased in the Atlantic Ocean due to rising demand.

  • Researchers study the habitats of geryonids to understand their role in the ocean ecosystem.

Morphology

geryonid = Geryon (opaque) = geryon + id

The taxonomic base is an obscure proper name and '-id' is a specialist suffix, so the compound is not transparent to average learners.

Etymology

Geryonid comes from the mythic name Geryon, a 'giant' with three bodies, and naturalists gave his name to a family of deep-sea crabs because of their strange, strong look. So a geryonid is a deep-sea crab in that family.
