Chondrichthyes General Characteristics and Examples Free Biology

Abstract - Data on chondrichthyes fished during 16 surveys as part of the MEDITS project carried out from 1994 to 2009 on trawlable bottoms up to 800m depth in all seas around Italy are.

Chondrichthyes or cartilaginous fishes are the sharks and their relatives. They have jaws and paired fins, paired nostrils, scales, two-chambered hearts, and skeletons made of cartilage rather than bone. They are divided into two subclasses: Elasmobranchii ( sharks, rays and skates) and Holocephali ( chimaera, sometimes called ghost sharks).

Understanding key aspects of the biology and ecology of chondrichthyan fishes (sharks, rays, and chimeras), as well as the range of threats affecting their populations is crucial given the rapid rate at which some species are declining. In the Eastern Tropical Pacific (ETP), the lack of knowledge, unreliable (or non-existent) landing statistics, and limited enforcement of existing fisheries.

Chondrichthyes The three Domain System

Chondrichthyes (/ k ɒ n ˈ d r ɪ k θ i. iː z /; from Ancient Greek χόνδρος (khóndros) 'cartilage', and ἰχθύς (ikhthús) 'fish') is a class of jawed fish that contains the cartilaginous fish or chondrichthyians, which all have skeletons primarily composed of cartilage.They can be contrasted with the Osteichthyes or bony fish, which have skeletons primarily composed of bone tissue.

In the present work, an overview of the demersal (sharks‐chimaera) and bottom dwelling (batoids) of experimental survey international bottom trawl survey in the mediterranean (MEDITS) data, from 1994 to 2013, is provided. The analysed data refer to a wide area located off the southern coast of Sicily, namely south of Sicily (according to the general fisheries commission for the mediterranean.

This collection represents the third in Italy for number of items and, with a total of 45 species placed in 21 families, is among the most important Chondrichthyan collection housed in Italian naturalistic museums. In particular, with 145. Elasmobranchs Pleurotremata (26 species) the collection is the fourth in Italy for number.

Sharks, batoids (rays and skates), and chimaeras are grouped in the class Chondrichthyes. 1,282 species of chondrichthyans are described globally. These include 1,226 of Elasmobranchii species (537.

This chapter reviews the current state of knowledge about global chondrichthyes bycatch, including how the combination of biological characteristics of these species and the impact of different fishing methods reflect their vulnerability to bycatch. Specifically, it summarizes the present status of elasmobranchs and chimaeras bycatch worldwide. Following this, it illustrates the main.

In 2014, the first global assessment of Chondrichthyes predicted that 24% of 1,041 species of sharks, rays and chimaeras were threatened. Now, a reassessment by Dulvy et al., in Current Biology.

Chondrichthyes MarineBiology

In this contribution the checklist of chondrichthyans of Calabria (Central Mediterranean, southern Italy) is reported. Data presented is derived from twenty years of opportunistic and active surveys from 2000 to 2020. A total of 55 species of chondrichthyans is present in Calabrian seas: 33 sharks, 20 rays, and 2 chimaeras. These species represent approximately 62% of the total reported for.
