Haematological changes in African lungfish, Protopterus annectens after aerial exposure.
نویسنده
چکیده
Specimens of the west African lungfish, Protopterus annectens (mean weight 294.3 g mean length 38.1 cm), procured from Agulu lake at Agulu in Anambra state, Nigeria were removed from the ambient water and exposed to complete aerial life for a period of seven consecutive days after which some of their haematological changes were determined. There were significant polycythaemia, leucocytosis, thrombocythaemia and elevation of haemoglobin contents (p<0.05). The importance of these haematological adjustments which the fish makes whilst subjected to complete aerial habitat prior to aestivation are discussed.

Hearing of the African lungfish (Protopterus annectens) suggests underwater pressure detection and rudimentary aerial hearing in early tetrapods.
In the transition from an aquatic to a terrestrial lifestyle, vertebrate auditory systems have undergone major changes while adapting to aerial hearing. Lungfish are the closest living relatives of tetrapods and their auditory system may therefore be a suitable model of the auditory systems of early tetrapods such as Acanthostega. Therefore, experimental studies on the hearing capabilities of l...
متن کاملHearing in the African lungfish (Protopterus annectens): pre-adaptation to pressure hearing in tetrapods?
Lungfishes are the closest living relatives of the tetrapods, and the ear of recent lungfishes resembles the tetrapod ear more than the ear of ray-finned fishes and is therefore of interest for understanding the evolution of hearing in the early tetrapods. The water-to-land transition resulted in major changes in the tetrapod ear associated with the detection of air-borne sound pressure, as evi...
متن کاملAestivation and brain of the African lungfish Protopterus annectens
Scientists have long been fascinated by animals undergoing aestivation, a state of torpor at high temperature, due to its great potential in fields ranging from medicine to space travel. The brain of the African lungfish is able to coordinate a whole-body response to induce aestivation and to arouse from aestivation.
متن کاملFunctional subdivision of fin protractor and retractor muscles underlies pelvic fin walking in the African lungfish Protopterus annectens.
African lungfish Protopterus annectens can produce rotational movements around the joint between the pelvis and the pelvic fin, allowing these animals to walk across benthic substrates. In tetrapods, limb rotation at the hip joint is a common feature of substrate-based locomotion. For sprawling tetrapods, rotation can involve nine or more muscles, which are often robust and span multiple joints...
متن کاملTrackways Produced by Lungfish During Terrestrial Locomotion
Some primarily aquatic vertebrates make brief forays onto land, creating traces as they do. A lack of studies on aquatic trackmakers raises the possibility that such traces may be ignored or misidentified in the fossil record. Several terrestrial Actinopterygian and Sarcopterygian species have previously been proposed as possible models for ancestral tetrapod locomotion, despite extant fishes b...
