Monograph of the Egyptian Octopuses Order: Octopoda (Cephalopoda: Mollusca). Part III

Rafik Riad¹

Abstract: Octopuses, cuttlefishes, squids and nautilii are important representatives of the class Cephalopoda. They play an important role in the sea food industry and also represent one of the main sources of protein food. The Cephalopods belong to the third trophic position in the food chain and progress one or two stages with age (Clark, 1966). All are carnivorous. They prey on a variety of crustacean and fish organisms. They themselves can be preys of diving birds, pelagic and benthic fish's seals and whales. It is … Show more

The geography of body size in cuttlefishes (Cephalopoda, Sepiidae)

This study explores body size in sepiids (Cephalopoda, Sepiidae) on the interspecific scale and provides an overview of their geographical distribution. Results reveal a highly skewed distribution of body size variation for raw values and a nearly normal distribution for log-transformed data. However, normality is not statistically validated due to the overrepresentation of small and large species. The geographical distribution of sepiids reveals five main clusters: Atlantic, Cape Basin, Indian Ocean, Asia-Pacific, and Australian. On average, clusters display more or less the same mean body size pattern except the Cape Basin cluster, which is statistically different from the others (smaller interspecific mean body size). The reasons remain unclear but a phylogenetic effect is suspected as southwest African coastal waters concentrate species from the ‘Hemisepius’ complex which is made up of small species. Sepiids do not obey Bergmann’s rule: species from high latitudes do not tend to be larger than species from low latitudes.

The present study identifies one species of the genus Octopus in the order: Octopoda (Cephalopoda: Mollusca), recorded forthe first time in the Iraqi coastal waters and Arabian-Persian Gulf. The study extended from January 2019 to December of thesame year. The Octopus specimens were seasonally obtained from the fishing trawlers operating in the Iraqi coastal waters inthe South of Al- Fao District, Basrah- Iraq, NW Arabian Gulf. The Octopus was identified as O. vulgaris in Iraqi coastal watersdepending on morphological features. The habitats of living specimens are briefly described. Some observations were reported on the occurrence of this species and the measurement of some environmental factors. The species was identified up to spe-cies level using standard literature. This species looks similar morphologically to the species which is already identified from the other areas around the world. The present study records significant expansion in the distribution range of this species.

Background and objective Antiepileptic drug Depakine® is often used, although it can cause birth defects in both human and animals. This study’s goal was to assess the Octopus vulgaris extract’s (OE) ability to protect against the hepatotoxicity caused by Depakine in an effort to advance its clinical application. Patients and methods Four groups of adult male Wistar rats (150–180 g b.w.) have been designed at random (10 rats each) as: 1) healthy control group; 2) healthy rats treated orally with OE (50 mg/kg/day); 3) rats administrated orally with Depakine® (500 mg/kg/day); 4) rats treated with OE in combination with Depakine. Results and conclusion After 6 weeks of treatment, the results demonstrated that OE was effective in lowering Depakine®-induced hepatotoxicity. This was shown by a significant rise in liver glutathione (GSH), superoxide dismutase (SOD), and catalase (CAT) values as well as albumin and total protein levels. Additionally, there was a considerable drop in the serum levels of tumor necrosis alpha (TNF-α), interlukin-1beta (IL-1β), interlukin-4 (IL-4), interlukin-6 (IL-6), and interlukin-10 (IL-10), which exacerbated the structural recovery of the liver’s histological image. Conclusion: OE was highly effective in reducing the oxidative stress caused by Depakine® and protecting the liver from its toxic effects. OE is a viable supplement candidate for liver protection against the negative effects of that antiepileptic medication.
