Now let us look at less extremely dialectal cases. For the majority of educated speakers in Spain and parts of Latin America, neither of the two tendencies ( a or b ) is enough on its own to justify the use of le/les ; but together they are. Thus, speakers who would reject sentences like le vi for "I saw it" and le vi for "I saw her" would nevertheless accept and use le vi for "I saw him". Indeed, this use of le to mean "him" is so common in standard Castilian speech that some would call the use of lo vi to mean "I saw him" an example of loísmo/laísmo , . the dialectalism whereby lo is overused. The Real Academia's current line is that le for "him" is officially "tolerated".
Larval sponges are small 50 microns to 5 millimetres in diametre. all known sponge larvae are ciliated though the cilia may be longer, shorter or absent from different parts of their surface. After release they swim or crawl for a period of time before settling down to begin life as a new miniature sponge. Swimming species tend to have a crawling phase immediately before settling down. This free living stage may last as long as 18 to 20 days in Polymastia spp. or be as short as 4 to 6 hours in genera such as Ophlitaspongia . Larval sponges are not complicated organisms, and there is much variation between species however many species have a positive phototaxis when they first leave their parents body which switches to a negative one before they enter the presettling stage. Some species have been shown to have a preliminary negative geotaxis while most species have shown a preference for surfaces with an algal or bacterial film. As with the larval stage so the time taken for the larvae to reorganise itself into and functioning sponge varies between species so that Microciona spp. are up and running within two days while Polymastia spp. can take as long as 7 days to get themselves sorted.
