Sagittiferidae

Sagittiferidae Symsagittifera schultzei Scientific classification Kingdom: Animalia Phylum: Xenacoelomorpha Class: Acoela Order: not assigned Family: Sagittiferidae Genera Antrosagittifera Convolutriloba [1] Praesagittifera Sagittifera Symsagittifera Sagittiferidae is a family of Acoela. Contents 1 Systematics 2 Characteristics 3 Species 3.1 Antrosagittifera 3.2 Convolutriloba 3.3 Sagittifera 3.4 Symsagittifera 4 References Systematics The family is divided into five genera ( see taxobox ) and contains about 20 species (Turbellarian taxonomic database, 2006). The affinities of the genera are as yet unclear. Some biologists prefer to exclude the genus Praesagittifera , leaving into the family only the genera with sagittocysts. [2] Characteristics Sagittiferidae are small flat worm-like animals. Several of them grow symbiotic algae Tetraselmis in their body cavity and t...

ArangoDB Graph Traversal fails inspite of increased heap size

Image
0 ArangoDB Version: 3.3.14 Heap Statistics for application: { total_heap_size: 39108608, total_heap_size_executable: 3670016, total_physical_size: 37433512, total_available_size: 8735662896, used_heap_size: 28891504, heap_size_limit: 8769069275, malloced_memory: 16384, peak_malloced_memory: 168484640, does_zap_garbage: 0 } I have a traversal api which traverses through 3 vertices and returns around 300 document vertices. For 200 I get the proper response but when I increase the number of vertices to 300, the traversal api throws an error invalid string length. I have increased the heap space for application to 8GB but as can be seen below the heap_used is way far too less. I am quite not sure if this issue is during serialization to JSON as there is sufficient heap memory available or...

Fragmentation (reproduction)

Image
Fragmentation in multicellular organisms is a form of asexual reproduction in which an organism is split into fragments. Each of these fragments develop into matured, fully grown individuals that are identical to their parents. The splitting may or may not be intentional – it may or may not occur due to man-made or natural damage by the environment or predators. This kind of organism may develop specific organs or zones that may be shed or easily broken off. If the splitting occurs without the prior preparation of the organism, both fragments must be able to regenerate the complete organism for it to function as reproduction. Fragmentation, also known as splitting, as a method of reproduction is seen in many organisms such as filamentous cyanobacteria, molds, lichens, many plants, and animals such as sponges, acoel flatworms, some annelid worms and sea stars.
